* Support parallel build trees (VPATH builds)Turbo Fredriksson2015-07-171-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Build products from an out of tree build should be written relative to the build directory. Sources should be referred to by their locations in the source directory. This is accomplished by adding the 'src' and 'obj' variables for the module Makefile.am, using relative paths to reference source files, and by setting VPATH when source files are not co-located with the Makefile. This enables the following: $ mkdir build $ cd build $ ../configure \ --with-spl=$HOME/src/git/spl/ \ --with-spl-obj=$HOME/src/git/spl/build $ make -s This change also has the advantage of resolving the following warning which is generated by modern versions of automake.

| | | | | | | | | | | | | | | | | | When using 'zpool import' to scan for available pools prefer vdev names which reference vdevs with more valid labels. There should be two labels at the start of the device and two labels at the end of the device. If labels are missing then the device has been damaged or is in some other way incomplete. Preferring names with fully intact labels helps weed out bad paths and improves the likelihood of being able to import the pool. This behavior only applies when scanning /dev/ for valid pools.

* Implement -t option to zpool create for temporary pool namesRichard Yao2014-09-301-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | Creating virtual machines that have their rootfs on ZFS on hosts that have their rootfs on ZFS causes SPA namespace collisions when the standard name rpool is used. The solution is either to give each guest pool a name unique to the host, which is not always desireable, or boot a VM environment containing an ISO image to install it, which is cumbersome. 26b42f3f9d03f85cc7966dc2fe4dfe9216601b0e introduced `zpool import -t ...` to simplify situations where a host must access a guest's pool when there is a SPA namespace conflict. We build upon that to introduce `zpool import -t tname ...`. That allows us to create a pool whose in-core name is tname, but whose on-disk name is the normal name specified. This simplifies the creation of machine images that use a rootfs on ZFS. That benefits not only real world deployments, but also ZFSOnLinux development by decreasing the time needed to perform rootfs on ZFS experiments.

| | | | | | | | | | | | | zpool import's -t parameter is intended for use with -R when operating on pools that belong to other systems. Like -R, pools imported in this way should not update the cachefile unless explicitly requested. The initial implementation allowed the cachefile to be updated when -R was not used.

| | | | | | | | | | | | | | | | | | | | | zpool_events_next() can be called in blocking mode by specifying a non-zero value for the "block" parameter. However, the design of the ZFS Event Daemon (zed) requires additional functionality from zpool_events_next(). Instead of adding additional arguments to the function, it makes more sense to use flags that can be bitwise-or'd together. This commit replaces the zpool_events_next() int "block" parameter with an unsigned bitwise "flags" parameter. It also defines ZEVENT_NONE to specify the default behavior. Since non-blocking mode can be specified with the existing ZEVENT_NONBLOCK flag, the default behavior becomes blocking mode. This, in effect, inverts the previous use of the "block" parameter. Existing callers of zpool_events_next() have been modified to check for the ZEVENT_NONBLOCK flag.

Subsequent calls to zpool_events_next() and zpool_events_seek() then require the file descriptor as an argument to reposition the cursor.

* Implement -t option to zpool import for temporary pool namesRichard Yao2014-03-201-1/+5
| | | | | | | | | | | | | | | | Originally, users had to handle spa namespace collisions by either exporting the already imported pool or by specifying a new name for the pool with a conflicting name. In the case of root pools from virtual guests, neither approach to collision resolution is reasonable. This is addressed by extending the new name syntax with a -t option to specify that the new name is temporary. When specified, this sets an internal flag that is passed into the kernel to tell it that all label updates should refer to the name used in the original label. Consequently, the original pool name will be retained on export. Signed-off-by: Richard Yao <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #2189

This was accomplished by adding an entry to zbookmark_t, which is included in a couple of on-disk structures. That lead to the creation of pools with incorrect dsl_scan_phys_t objects that could only be imported by versions of ZoL containing that commit. Such pools cannot be imported by other versions of ZFS or past versions of ZoL. The additional field has been removed by the previous commit. However, affected pools must be imported and scrubbed using a version of ZoL with this commit applied. This will return the pools to a state in which they may be imported by other implementations. The 'zpool import' or 'zpool status' command can be used to determine if a pool is impacted. A message similar to one of the following means your pool must be scrubbed to restore compatibility. $ zpool import pool: zol-0.6.2-173 id: 1165955789558693437 state: ONLINE status: Errata #1 detected. action: The pool can be imported using its name or numeric identifier, however there is a compatibility issue which should be corrected by running 'zpool scrub' see: http://zfsonlinux.org/msg/ZFS-8000-ER config: ... $ zpool status pool: zol-0.6.2-173 state: ONLINE scan: pool compatibility issue detected. see: https://github.com/zfsonlinux/zfs/issues/2094 action: To correct the issue run 'zpool scrub'. config: ... If there was an async destroy in progress 'zpool import' will prevent the pool from being imported. Further advice on how to proceed will be provided by the error message as follows. $ zpool import pool: zol-0.6.2-173 id: 1165955789558693437 state: ONLINE status: Errata #2 detected. action: The pool can not be imported with this version of ZFS due to an active asynchronous destroy. Revert to an earlier version and allow the destroy to complete before updating. see: http://zfsonlinux.org/msg/ZFS-8000-ER config: ... Pools affected by the damaged dsl_scan_phys_t can be detected prior to an upgrade by running the following command as root: zdb -dddd poolname 1 | grep -P '^\t\tscan = ' | sed -e 's;scan = ;;' | wc -w Note that `poolname` must be replaced with the name of the pool you wish to check. A value of 25 indicates the dsl_scan_phys_t has been damaged. A value of 24 indicates that the dsl_scan_phys_t is normal. A value of 0 indicates that there has never been a scrub run on the pool. The regression caused by the change to zbookmark_t never made it into a tagged release, Gentoo backports, Ubuntu, Debian, Fedora, or EPEL stable respositorys. Only those using the HEAD version directly from Github after the 0.6.2 but before the 0.6.3 tag are affected. This patch does have one limitation that should be mentioned. It will not detect errata #2 on a pool unless errata #1 is also present. It expected this will not be a significant problem because pools impacted by errata #2 have a high probably of being impacted by errata #1. End users can ensure they do no hit this unlikely case by waiting for all asynchronous destroy operations to complete before updating ZoL. The presence of any background destroys on any imported pools can be checked by running `zpool get freeing` as root. This will display a non-zero value for any pool with an active asynchronous destroy. Lastly, it is expected that no user data has been lost as a result of this erratum.

* Add generic errata infrastructureBrian Behlendorf2014-02-211-2/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From time to time it may be necessary to inform the pool administrator about an errata which impacts their pool. These errata will by shown to the administrator through the 'zpool status' and 'zpool import' output as appropriate. The errata must clearly describe the issue detected, how the pool is impacted, and what action should be taken to resolve the situation. Additional information for each errata will be provided at http://zfsonlinux.org/msg/ZFS-8000-ER. To accomplish the above this patch adds the required infrastructure to allow the kernel modules to notify the utilities that an errata has been detected. This is done through the ZPOOL_CONFIG_ERRATA uint64_t which has been added to the pool configuration nvlist. To add a new errata the following changes must be made: * A new errata identifier must be assigned by adding a new enum value to the zpool_errata_t type. New enums must be added to the end to preserve the existing ordering. * Code must be added to detect the issue. This does not strictly need to be done at pool import time but doing so will make the errata visible in 'zpool import' as well as 'zpool status'. Once detected the spa->spa_errata member should be set to the new enum. * If possible code should be added to clear the spa->spa_errata member once the errata has been resolved. * The show_import() and status_callback() functions must be updated to include an informational message describing the errata. This should include an action message describing what an administrator should do to address the errata. * The documentation at http://zfsonlinux.org/msg/ZFS-8000-ER must be updated to describe the errata. This space can be used to provide as much additional information as needed to fully describe the errata. A link to this documentation will be automatically generated in the output of 'zpool import' and 'zpool status'.

* Use expected zpool_status_t typeBrian Behlendorf2014-02-211-2/+2
| | | | | | | | | | | | | | | Both the zpool_import_status() and zpool_get_status() functions return the zpool_status_t enum. This explicit type should be used rather than the more generic int type. This patch makes no functional change and should only be considered code cleanup. It happens to have been done in the context of #2094 because that's when I noticed this issue.

* Properly link zpool command to libblkidRichard Yao2014-01-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 31fc19399e597e3391f19f1392ab120f1de0d5f2 incorrectly removed $(LIBBLKID) from cmd/zpool/Makefile.am. This meant that the toolchain was not given -lblkid, which resulted in the following build failure on Ubuntu 13.10: /usr/bin/ld: zpool_vdev.o: undefined reference to symbol 'blkid_put_cache@@BLKID_1.0' /lib/x86_64-linux-gnu/libblkid.so.1: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status That commit reworked various Makefile.am to follow best practices, so we reintroduce $(LIBBLKID) in a manner consistent with that, rather than explicitly reverting the change. Reproduction of this issue was done on a Gentoo Linux system by executing the following commands: zfs create -o mountpoint=/mnt/ubuntu-13.10 rpool/ROOT/ubuntu-13.10 debootstrap --variant=buildd --arch amd64 saucy /mnt/ubuntu-13.10 http://archive.ubuntu.com/ubuntu/ mount -o bind /dev /mnt/ubuntu-13.10/dev/ mount -o bind /proc/ /mnt/ubuntu-13.10/proc/ mount -o bind /sys/ /mnt/ubuntu-13.10/sys/ cp /etc/resolv.conf /mnt/ubuntu-13.10/etc/ (cd /mnt/ubuntu-13.10/root/ && git clone git://github.com/zfsonlinux/zfs.git) chroot /mnt/ubuntu-13.10/ apt-get install git autoconf libtool zlib1g-dev uuid-dev libblkid-dev \#apt-get install alien fakeroot vim cd /root/zfs ./autogen.sh ./configure --with-config=user --prefix=/usr make That will create a Ubuntu 13.10 chroot, fetch the sources and build test. At this point, cmd/zpool/Makefile.am was modified and the following commands were run to verify that the build issue was resolved: git clean -xdf ./autogen.sh ./configure --with-config=user --prefix=/usr make Although it is not shown here, the absence of libblkid-dev enables ZFS to build successfully without the patch. This could explain how this escaped detection until recently. A test without libblkid-dev was done to verify that the patch did not cause a regression in the absence of libblkid: apt-get remove libblkid-dev git clean -xdf ./autogen.sh ./configure --with-config=user --prefix=/usr make Additionally, the commands themselves were tested against my live system from within the chroot to ensure basic functionality. My live system had corresponding kernel modules already installed and basic commands such as `zpool list` and `zfs list` worked without incident. Lastly, this patch was also build tested on Gentoo Linux, where it caused no problems. At time of writing, these steps can be used to reproduce these results on any modern Linux system that has debootstrap installed. On Gentoo, installing debootstrap can be done with `emerge dev-util/debootstrap`. The current ZFSOnLinux HEAD revision as of writing is fd23720ae14dca926800ae70e6c8f4b4f82efc08. Once this is fixed in HEAD, either that revision or another before this fix and after 31fc19399e597e3391f19f1392ab120f1de0d5f2 will be needed to reproduce this issue. Lastly, it remains to be seen why the toolchains on the systems performing regression tests did not catch this. This is not a ZFS-specific issue, but it is something that we will want to explore in the future.

| | | | | | | | | | | | | | | | | | The vast majority of these changes are in Linux specific code. They are the result of not having an automated style checker to validate the code when it was originally written. Others were caused when the common code was slightly adjusted for Linux. This patch contains no functional changes. It only refreshes the code to conform to style guide. Everyone submitting patches for inclusion upstream should now run 'make checkstyle' and resolve any warning prior to opening a pull request. The automated builders have been updated to fail a build if when 'make checkstyle' detects an issue. Signed-off-by: Brian Behlendorf <[email protected]> Closes #1821

* Increase default udev wait timeBrian Behlendorf2013-10-221-1/+1
| | | | | | | | | | | | | | | | | | When creating a new pool, or adding/replacing a disk in an existing pool, partition tables will be automatically created on the devices. Under normal circumstances it will take less than a second for udev to create the expected device files under /dev/. However, it has been observed that if the system is doing heavy IO concurrently udev may take far longer. If you also throw in some cheap dodgy hardware it may take even longer. To prevent zpool commands from failing due to this the default wait time for udev is being increased to 30 seconds. This will have no impact on normal usage, the increase timeout should only be noticed if your udev rules are incorrectly configured. Signed-off-by: Brian Behlendorf <[email protected]> Closes #1646

* Generate libraries with correct DT_NEEDED entriesRichard Yao2013-10-101-2/+0
| | | | | | | | | | | | | | | | | | | | Libraries that depend on other libraries should list them in ELF's DT_NEEDED field so that programs linking to them do not need to specify those libraries unless they depend on them as well. This is not the case in the current code and the consequence is that anything that needs a library must know its dependencies. This is fragile and caused GRUB2's configure script to break when a dependency was added on libblkid in libzfs. This resolves that problem by using LIBADD/LDADD to specify libraries in Makefile.am instead of LDFLAGS. This ensures that proper DT_NEEDED entries are generated and prevents GRUB2's configure script from breaking in the presence of a libblkid dependency. This also removes unneeded dependencies from various files. Signed-off-by: Richard Yao <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Issue #1751

That means that the zfs/zpool utilities built from master are NOT compatible with the 0.6.2 kernel modules. Ensure you load the matching kernel modules from master after updating the utilities. Otherwise the zfs/zpool commands will be unable to interact with your pool and you will see errors similar to the following: $ zpool list failed to read pool configuration: bad address no pools available $ zfs list no datasets available Add zvol minor device creation to the new zfs_snapshot_nvl function. Remove the logging of the "release" operation in dsl_dataset_user_release_sync(). The logging caused a null dereference because ds->ds_dir is zeroed in dsl_dataset_destroy_sync() and the logging functions try to get the ds name via the dsl_dataset_name() function. I've got no idea why this particular code would have worked in Illumos. This code has subsequently been completely reworked in Illumos commit 3b2aab1 (3464 zfs synctask code needs restructuring). Squash some "may be used uninitialized" warning/erorrs. Fix some printf format warnings for %lld and %llu. Apply a few spa_writeable() changes that were made to Illumos in illumos/illumos-gate.git@cd1c8b8 as part of the 3112, 3113, 3114 and 3115 fixes.
