* zfs-functions.in: is_mounted() always returns 1TerraTech2018-12-041-2/+7
| | | | | | | | | | | | | | The 'while read line; ...; done' loop is run in a piped subshell therefore the 'return 0' would not cause a return from the is_mounted() function. In all cases, this function will always return 1. The fix is to 'return 1' from the subshell on a successful match (no match == return 0), and then negating the final return value.

* OpenZFS 7793 - ztest fails assertion in dmu_tx_willuse_spaceBrian Behlendorf2017-03-071-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reviewed by: Steve Gonczi <[email protected]> Reviewed by: George Wilson <[email protected]> Reviewed by: Pavel Zakharov <[email protected]> Ported-by: Brian Behlendorf <[email protected]> Background information: This assertion about tx_space_* verifies that we are not dirtying more stuff than we thought we would. We “need” to know how much we will dirty so that we can check if we should fail this transaction with ENOSPC/EDQUOT, in dmu_tx_assign(). While the transaction is open (i.e. between dmu_tx_assign() and dmu_tx_commit() — typically less than a millisecond), we call dbuf_dirty() on the exact blocks that will be modified. Once this happens, the temporary accounting in tx_space_* is unnecessary, because we know exactly what blocks are newly dirtied; we call dnode_willuse_space() to track this more exact accounting. The fundamental problem causing this bug is that dmu_tx_hold_*() relies on the current state in the DMU (e.g. dn_nlevels) to predict how much will be dirtied by this transaction, but this state can change before we actually perform the transaction (i.e. call dbuf_dirty()). This bug will be fixed by removing the assertion that the tx_space_* accounting is perfectly accurate (i.e. we never dirty more than was predicted by dmu_tx_hold_*()). By removing the requirement that this accounting be perfectly accurate, we can also vastly simplify it, e.g. removing most of the logic in dmu_tx_count_*(). The new tx space accounting will be very approximate, and may be more or less than what is actually dirtied. It will still be used to determine if this transaction will put us over quota. Transactions that are marked by dmu_tx_mark_netfree() will be excepted from this check. We won’t make an attempt to determine how much space will be freed by the transaction — this was rarely accurate enough to determine if a transaction should be permitted when we are over quota, which is why dmu_tx_mark_netfree() was introduced in 2014. We also won’t attempt to give “credit” when overwriting existing blocks, if those blocks may be freed. This allows us to remove the do_free_accounting logic in dbuf_dirty(), and associated routines. This logic attempted to predict what will be on disk when this txg syncs, to know if the overwritten block will be freed (i.e. exists, and has no snapshots).

* zfs-import: Perform verbatim import using cache fileJames Lee2015-10-132-64/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change modifies the import service to use the default cache file to perform a verbatim import of pools at boot. This fixes code that searches all devices and imported all visible pools. Using the cache file is in keeping with the way ZFS has always worked, how Solaris, Illumos, FreeBSD, and systemd performs imports, and is how it is written in the man page (zpool(1M,8)): All pools in this cache are automatically imported when the system boots. Importantly, the cache contains important information for importing multipath devices, and helps control which pools get imported in more dynamic environments like SANs, which may have thousands of visible and constantly changing pools, which the ZFS_POOL_EXCEPTIONS variable is not equipped to handle. Verbatim imports prevent rogue pools from being automatically imported and mounted where they shouldn't be. The change also stops the service from exporting pools at shutdown. Exporting pools is only meant to be performed explicitly by the administrator of the system. The old behavior of searching and importing all visible pools is preserved and can be switched on by heeding the warning and toggling the ZPOOL_IMPORT_ALL_VISIBLE variable in /etc/default/zfs.

* Reorder zfs-* services to allow /var on separate datasetJames Lee2015-09-025-46/+45
| | | | | | | | | | | | | | | | | | | | | | | | | ZED depends on /var. When /var is a separate dataset, it must be mounted before starting ZED. This change moves the zfs-zed service from starting first, to starting after zfs-mount, but before zfs-share. As discussed in issue #3513, ZED does not need to start first in order to consume events made during the zfs-import and zfs-mount services. The events will be queued and can be handled later in the boot process. ZED may, however, handle sharing in the future, so it should be started before the zfs-share service. This commit also stops the zfs-import service from writing temp files to /var/tmp on shutdown and it corrects the return code for the OpenRC service.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Additional SYSV init script fixes.Turbo Fredriksson2015-06-171-7/+10
| | | | | | | | | | | | | | | | | | | | Use the 'mount' command instead of /proc/mounts to get a list of matching filesystems. This because /proc/mounts reports a pool with a space 'rpool 1' as 'rpool\0401'. The space is encoded as 3-digit octal which is legal. However 'printf "%b"', which we use to filter out other illegal characters (such as slash, space etc) can't properly interpret this because it expects 4-digit octal. We get a  instead of the space we expected. The correct value should have been 'rpool\00401' (note the additional leading zero).

Primarily used in initrd scripts to allow for when filesystem needed to boot (such as /usr, /opt, /var etc) isn't directly under the root dataset. * ZFS_POOL_EXCEPTIONS Exclude pools from being imported (in the initrd and/or init scripts). * ZFS_DKMS_ENABLE_DEBUG, ZFS_DKMS_ENABLE_DEBUG_DMU_TX, ZFS_DKMS_DISABLE_STRIP Set to control how dkms should build the dkms packages. * ZPOOL_IMPORT_PATH Set path(s) where "zpool import" should import pools from. This was previously the job of "USE_DISK_BY_ID" (which is still used for backwards compatibility) but was renamed to allow for better control of import path(s). * If old USE_DISK_BY_ID is set, but not new ZPOOL_IMPORT_PATH, then we set ZPOOL_IMPORT_PATH to sane defaults just to be on the safe side. * ZED_ARGS To allow for local options to zed without having to change the init script. * The import function, do_import(), imports pools by name instead of '-a' for better control of pools to import and from where. * If USE_DISK_BY_ID is set (for backwards compatibility), but isn't 'yes' then ignore it. * If pool(s) isn't found with a simple "zpool import" (seen it happen), try looking for them in /dev/disk/by-id (if it exists). Any duplicates (pools found with both commands) is filtered out. * IF we have found extra pool(s) this way, we must force USE_DISK_BY_ID so that the first, simple "zpool import $pool" is able to find it. * Fallback on importing the pool using the cache file (if it exists) only if 'simple' import (either with ZPOOL_IMPORT_PATH or the 'built in' defaults) didn't work. * The export function, do_export(), will export all pools imported, EXCEPT the root pool (if there is one). * ZED script from the Debian GNU/Linux packages added. * Refreshed ZED init script from behlendorf@5e7a660 to be portable so it may be used on both LSB and Redhat style systems. * If there is no pool(s) imported and zed successfully shut down, we will unload the zfs modules. * The function library file for the ZoL init script is installed as /etc/init.d/zfs-functions. * The four init scripts, the /etc/{defaults,sysconfig,conf.d}/zfs config file as well as the common function library is tagged as '%config(noreplace)' in the rpm rules file to make sure they are not replaced automatically if locally modifed. * Pitfals and workarounds: * If we're running from init, remove stale /etc/dfs/sharetab before importing pools in the zfs-import init script. * On Debian GNU/Linux, there's a 'sendsigs' script that will kill basically everything quite early in the shutdown phase and zed is/should be stopped much later than that. We don't want zed to be among the ones killed, so add the zed pid to list of pids for 'sendsigs' to ignore. * CentOS uses echo_success() and echo_failure() to print out status of command. These in turn uses "echo -n \0xx[etc]" to move cursor and choose colour etc. This doesn't work with the modified IFS variable we need to use in zfs-import for some reason, so work around that when we define zfs_log_{end,failure}_msg() for RedHat and derivative distributions. * All scripts passes ShellCheck (with one false positive in do_mount()).

* Update init script to allow /dev/disk/by-id importTurbo Fredriksson2013-12-061-2/+13
| | | | | | | | | | | | Many people prefer to use by-id at import time instead of using the cache file. This can be a much better solution than the cache file in some environments so we're adding some infrastructure to allow it. This functionality is disabled by default.

* Improve OpenRC init scriptRichard Yao2013-06-181-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current zfs OpenRC script's dependencies cause OpenRC to attempt to unmount ZFS filesystems at shutdown while things were still using them, which would fail. This is a cosmetic issue, but it should still be addressed. It probably does not affect systems where the rootfs is a legacy filesystem, but any system with the rootfs on ZFS needs to run the ZFS init script after the system is ready to shutdown filesystems. OpenRC's shutdown process occurs in the reverse order of the startup process. Therefore running the ZFS shutdown procedure after filesystems are ready to be unmounted requires running the startup procedure before fstab. This patch changes the dependencies of the script to expliclty run before fstab at boot when the rootfs is ZFS and to run after fstab at boot whenever the rootfs is not ZFS. This should cover most use cases. The only cases not covered well by this are systems with legacy root filesystems where people want to configure fstab to mount a non-ZFS filesystem off a zvol and possibly also systems whose pools are stored on network block devices. The former requires that the ZFS script run before fstab, which could cause ZFS datasets to mount too early and appear under the fstab mount points. The latter requires that the ZFS script run after networking starts, which precludes the ability to store any system information on ZFS. An additional OpenRC script could be written to handle non-root pools on network block devices, but that will depend on user demand and developer time.

* Remove ARCH packagingBrian Behlendorf2013-03-062-64/+1
| | | | | | | | | | | | | | The kernel modules are now available in the Arch User Repository (AUR) via zfs. Since their packaging is maintained and superior to ours it is being removed from the tree. https://wiki.archlinux.org/index.php/ZFS Now that various distributions are picking up the packages we should eventually be able to remove most of this infrastructure. Packaging belongs with the distributions not upstream. Signed-off-by: Brian Behlendorf <[email protected]>

* Set zvol discard_granularity to the volblocksize.Etienne Dechamps2012-08-071-0/+1
| | | | | | | | | | | | | | | | | | Currently, zvols have a discard granularity set to 0, which suggests to the upper layer that discard requests of arbirarily small size and alignment can be made efficiently. In practice however, ZFS does not handle unaligned discard requests efficiently: indeed, it is unable to free a part of a block. It will write zeros to the specified range instead, which is both useless and inefficient (see dnode_free_range). With this patch, zvol block devices expose volblocksize as their discard granularity, so the upper layer is aware that it's not supposed to send discard requests smaller than volblocksize.

* Linux 3.5 compat, end_writeback() changed to clear_inode()Richard Yao2012-07-231-0/+1
| | | | | | | | | | | | | | | | The end_writeback() function was changed by moving the call to inode_sync_wait() earlier in to evict(). This effecitvely changes the ordering of the sync but it does not impact the details of the zfs implementation. However, as part of this change end_writeback() was renamed to clear_inode() to reflect the new semantics. This change does impact us and clear_inode() now maps to end_writeback() for kernels prior to 3.5.

This interface used to take the child dentry and a bool describing if the parent is needed.

This code should be audited to make sure we're doing the right thing. Signed-off-by: Richard Yao <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Issue #784
* Move partition scanning from userspace to module.Etienne Dechamps2012-07-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, zpool online -e (dynamic vdev expansion) doesn't work on whole disks because we're invoking ioctl(BLKRRPART) from userspace while ZFS still has a partition open on the disk, which results in EBUSY. This patch moves the BLKRRPART invocation from the zpool utility to the module. Specifically, this is done just before opening the device in vdev_disk_open() which is called inside vdev_reopen(). This requires jumping through some hoops to get to the disk device from the partition device, and to make sure we can still open the partition after the BLKRRPART call. Note that this new code path is triggered on dynamic vdev expansion only; other actions, like creating a new pool, are unchanged and still call BLKRRPART from userspace. This change also depends on API changes which are available in 2.6.37 and latter kernels. The build system has been updated to detect this, but there is no compatibility mode for older kernels. This means that online expansion will NOT be available in older kernels. However, it will still be possible to expand the vdev offline. Signed-off-by: Brian Behlendorf <[email protected]> Closes #808
* Relicense zfs.gentoo.in from GPLv2 to 2-clause BSDRichard Yao2012-07-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | As the Gentoo sys-fs/zfs maintainer, I receive license compatibility questions and at times, those questions can be harassing. I feel that the presence of the GPL in Gentoo's package metadata promotes such questions. zfs.gentoo.in is the only GPLv2 licensed file in ZFS, so I have taken the liberty of contacting all contributors to this file to request permission to relicense it. All of the contributors to this file have agreed to relicense it under the 2-clause BSD license. I have added their Signed-offs to this commit, in order of first contribution. Thank you everyone for being so understanding.
