* Return -EOPNOTSUPP for ZFS_IOC_{GET|SET}FLAGSBrian Behlendorf2013-06-262-0/+32
| | | | | | | | | | Until these hooks are fully implemented return the expected -EOPNOTSUPP error to indicate they are not functional. This allows test suites such as xfstests to cleanly skip testing this functionality until it's implemented. Signed-off-by: Brian Behlendorf <[email protected]> Issue #229
* Allow fetching the pool from the device at mountBrian Behlendorf2013-06-261-4/+42
| | | | | | | | | | | To simplify integration with the xfstests test suite the mount.zfs helper has been extended. When passed a block device (/dev/sdX) to mount, instead of a pool/dataset, the pool name will be read from any existing zfs label and used. This allows you to mount the root dataset of a zfs filesystem by specifing any of the member vdevs. Signed-off-by: Brian Behlendorf <[email protected]>

* Register correct handlers in nvlist_alloc()Brian Behlendorf2013-06-203-4/+38
| | | | | | | | | | | | | | | | | | The non-blocking allocation handlers in nvlist_alloc() would be mistakenly assigned if any flags other than KM_SLEEP were passed. This meant that nvlists allocated with KM_PUSHPUSH or other KM_* debug flags were effectively always using atomic allocations. While these failures were unlikely it could lead to assertions because KM_PUSHPAGE allocations in particular are guaranteed to succeed or block. They must never fail. Since the existing API does not allow us to pass allocation flags to the private allocators the cleanest thing to do is to add a KM_PUSHPAGE allocator.

On dcenter, we saw that we were caching ~256GB of metadata, while the pool only had <4GB of metadata on disk. We were wasting about half the system's RAM (252GB) on blocks that have been freed. Even though these freed blocks will never be used again, and thus will eventually be evicted, this causes us to use memory inefficiently for 2 reasons: 1. A block that is freed has no chance of being accessed again, but will be kept in memory preferentially to a block that was accessed before it (and is thus older) but has not been freed and thus has at least some chance of being accessed again. 2. We partition the ARC into several buckets: user data that has been accessed only once (MRU) metadata that has been accessed only once (MRU) user data that has been accessed more than once (MFU) metadata that has been accessed more than once (MFU) The user data vs metadata split is somewhat arbitrary, and the primary control on how much memory is used to cache data vs metadata is to simply try to keep the proportion the same as it has been in the past (each bucket "evicts against" itself). The secondary control is to evict data before evicting metadata. Because of this bucketing, we may end up with one bucket mostly containing freed blocks that are very old, while another bucket has more recently accessed, still-allocated blocks. Data in the useful bucket (with still-allocated blocks) may be evicted in preference to data in the useless bucket (with old, freed blocks). On dcenter, we saw that the MFU metadata bucket was 230MB, while the MFU data bucket was 27GB and the MRU metadata bucket was 256GB. However, the vast majority of data in the MRU metadata bucket (256GB) was freed blocks, and thus useless. Meanwhile, the MFU metadata bucket (230MB) was constantly evicting useful blocks that will be soon needed. The problem of cache segmentation is a larger problem that needs more investigation. However, if we stop caching freed blocks, it should reduce the impact of this more fundamental issue.

* Fix compile warning on 32-bit systemsYing Zhu2013-06-191-1/+1
| | | | | | | | | | | | | The definition of zfs_vdev_holder casts VDEV_HOLDER into a function pointer passing to linux kernel's block layer function blkdev_get_by_path. However current VDEV_HOLDER is defined to be wider than 32 bits and the compiler warns about potential overflows.

* 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.

* Don't leak mount flags into kernelNed Bass2013-06-182-13/+4
| | | | | | | | | | | | | | | | | | | | | | | | When calling mount(), care must be taken to avoid passing in flags that are used only by the user space utilities. Otherwise we may stomp on flags that are reserved for other purposes in the kernel. In particular, openSUSE 12.3 kernels have added a new MS_RICHACL super-block flag whose value conflicts with our MS_COMMENT flag. This causes incorrect behavior such as the umask being ignored. The MS_COMMENT flag essentially serves as a placeholder in the option_map data structure of zfs_mount.c, but its value is never used. Therefore we can avoid the conflict by defining it to 0. The MS_USERS, MS_OWNER, and MS_GROUP flags also conflict with reserved flags in the kernel. While this is not known to have caused any problems, it is nevertheless incorrect. For the purposes of the mount.zfs helper, the "users", "owner", and "group" options just serve as hints to set additional implied options. Therefore we now define their associated mount flags in terms of the options that they imply rather than giving them unique values. Signed-off-by: Brian Behlendorf <[email protected]> Closes #1457

* Use taskq for dump_bytes()Brian Behlendorf2013-05-065-6/+69
| | | | | | | | | | | | | | | | | | | The vn_rdwr() function performs I/O by calling the vfs_write() or vfs_read() functions. These functions reside just below the system call layer and the expectation is they have almost the entire 8k of stack space to work with. In fact, certain layered configurations such as ext+lvm+md+multipath require the majority of this stack to avoid stack overflows. To avoid this posibility the vn_rdwr() call in dump_bytes() has been moved to the ZIO_TYPE_FREE, taskq. This ensures that all I/O will be performed with the majority of the stack space available. This ends up being very similiar to as if the I/O were issued via sys_write() or sys_read(). Signed-off-by: Brian Behlendorf <[email protected]> Closes #1399 Closes #1423

We also optimized the taskq implementation in zfsonlinux/spl@3c6ed54. These changes significantly improved unlink performance to acceptable levels. This patch further reduces time spent spinning on this lock by randomly dispatching the work items over multiple independent task queues. The Illumos ZFS developers stated that this lock contention only arose after "3329 spa_sync() spends 10-20% of its time in spa_free_sync_cb()" was landed. It's not clear if 3329 affects the Linux port or not. I didn't see spa_free_sync_cb() show up in oprofile sessions while unlinking large files, but I may just not have used the right test case. I tested unlinking a 1 TB of data with and without the patch and didn't observe a meaningful difference in elapsed time. However, oprofile showed that the percent time spent in taskq_thread() was reduced from about 16% to about 5%. Aside from a possible slight performance benefit this may be worth landing if only for the sake of maintaining consistency with upstream. Ported-by: Ned Bass <[email protected]> Closes #1327

For consistenty with the vdev_disk.c code the upstream version leverages the Illumos bio interfaces. This makes sense for Illumos but not for ZoL for two reasons. 1) The vdev_disk.c code in ZoL has been rewritten to use the Linux block device interfaces which differ significantly from those in Illumos. Therefore, updating the vdev_file.c to use the Illumos interfaces doesn't get you consistency with vdev_disk.c. 2) Using the upstream patch as is would requiring implementing compatibility code for those Solaris block device interfaces in user and kernel space. That additional complexity could lead to confusion and doesn't buy us anything. For these reasons I've opted to simply move the existing vn_rdwr() as is in to the taskq function. This has the advantage of being low risk and easy to understand. Moving the vn_rdwr() function in to its own taskq thread also neatly avoids the possibility of a stack overflow. Finally, because of the additional work which is being handled by the free taskq the number of threads has been increased. The thread count under Illumos defaults to 100 but was decreased to 2 in commit 08d08e due to contention. We increase it to 8 until the contention can be address by porting Illumos #3581.

| | | | | | | | | | | | | | | | | | The previous code was only waiting for the symver file. But the postinst target of the DKMS script for SPL will not only create the symvers file, but also the header spl_config.h. If we are waiting in the configure script of ZFS for the SPL symvers file, then we also need to wait for spl_config.h. Otherwise the configure script will abort because the spl_config.h is not yet available. On top of that, the function ZFS_AC_SPL_MODULE_SYMVERS is moved to the end of the function ZFS_AC_SPL to allow both checks share the with-spl-timeout parameter.

| | | | | | | | | | | | | | | | | | A deadlock was accidentally introduced by commit e95853a which can occur when the system is under memory pressure. What happens is that while the txg_quiesce thread is holding the tx->tx_cpu locks it enters memory reclaim. In the context of this memory reclaim it then issues synchronous I/O to a ZVOL swap device. Because the txg_quiesce thread is holding the tx->tx_cpu locks a new txg cannot be opened to handle the I/O. Deadlock. The fix is straight forward. Move the memory allocation outside the critical region where the tx->tx_cpu locks are held.

* Allow setting a lower ashift with -o ashiftMartin Matuska2013-04-121-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous patches have allowed you to set an increased ashift to avoid doing 512b IO with 4k sector devices. However, it was not possible to set the ashift lower than the reported physical sector size even when a smaller logical size was supported. In practice, there are several cases where settong a lower ashift is useful: * Most modern drives now correctly report their physical sector size as 4k. This causes zfs to correctly default to using a 4k sector size (ashift=12). However, for some usage models this new default ashift value causes an unacceptable increase in space usage. Filesystems with many small files may see the total available space reduced to 30-40% which is unacceptable. * When replacing a drive in an existing pool which was created with ashift=9 a modern 4k sector drive cannot be used. The 'zpool replace' command will issue an error that the new drive has an 'incompatible sector alignment'. However, by allowing the ashift to be manual specified as smaller, non-optimal, value the device may still be safely used.

| | | | | | | | | | For the DKMS package to successfully build the kernel-devel headers must be included along gcc, make, and perl. The ZFS code never directly invokes perl but the kernel build system depends on it. Signed-off-by: Brian Behlendorf <[email protected]> Closes #1380
* Replace the ZFS_AC_META perl dependency with awkBrian Behlendorf2013-04-021-31/+56
| | | | | | | | | The only remaining perl dependency is part of the ZFS_AC_META macro. By eliminating this and replacing it with awk we can avoid the need to pull in perl to rebuild the packages. Signed-off-by: Brian Behlendorf <[email protected]> Issue #1380
* Only require spl-devel-kmod = %{version}Brian Behlendorf2013-04-021-1/+1
| | | | | | | | | | | | | Commit f6fb7651a0d05b357dc179cc4853263ce15da6ed introduced the idea of working builds which work correctly. However, because the zfs-kmod depends on a specific 'spl-devel-kmod = {version}-%{release}' package and the release component is unique the dependency is never satisfied. This requires line was introduced to ensure the correct version of the spl is always used. In this context only the version number is required so the release component has been dropped to satisfy the dependency. Signed-off-by: Brian Behlendorf <[email protected]>
* Automake 1.10.1 compat: AM_SILENT_RULESBrian Behlendorf2013-04-021-1/+1
| | | | | | | | | | | | | | | | | | | Part of the automated testing involves building the source on Debian Lenny which ships an ancient version of automake (1.10.1). Historically, this has caused a non-fatal warning about AM_SILENT_RULES not being defined. But when the autogen.sh script was updated to use autoreconf the warning became fatal. configure.ac:31: warning: macro `AM_SILENT_RULES' not found in library autoreconf: running: /usr/bin/autoconf --force configure.ac:34: error: possibly undefined macro: AM_SILENT_RULES If this token and others are legitimate, please use m4_pattern_allow. To resolve this build issue the call to AM_SILENT_RULES has been wrapped by m4_ifdef(). This prevents the macro from being expanded on platforms where it's undefined.

* Include init scripts in packagesBrian Behlendorf2013-03-261-2/+1
| | | | | | | | | | The distribution specific init scripts where excluded from the packaging when it was reworked. The intention is to replace them with systemd equivilants. However, that work has not yet been done and the init scripts are still useful so they have been added back in to the packaging. Signed-off-by: Brian Behlendorf <[email protected]>
* Provide ${kmodname}-devel-kmod for yum-builddepBrian Behlendorf2013-03-253-3/+6
| | | | | | | | | | | | | | In order to ensure that yum-builddep pulls in all the build requirements a generic ${kmodname}-devel-kmod provides line is added. This allows a version of the development headers to be included without requiring knowledge of the kernel version. This is important because unlike rpmbuild which does correctly expand the source rpm spec file, yum-builddep does not. Without this generic provides line mock which relies on yum-builddep is unable to automatically satisfy the dependency. Signed-off-by: Brian Behlendorf <[email protected]>
