* Remove dependency on sharetab file and refactor sharing logicGeorge Wilson2020-07-132-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | == Motivation and Context The current implementation of 'sharenfs' and 'sharesmb' relies on the use of the sharetab file. The use of this file is os-specific and not required by linux or freebsd. Currently the code must maintain updates to this file which adds complexity and presents a significant performance impact when sharing many datasets. In addition, concurrently running 'zfs sharenfs' command results in missing entries in the sharetab file leading to unexpected failures. == Description This change removes the sharetab logic from the linux and freebsd implementation of 'sharenfs' and 'sharesmb'. It still preserves an os-specific library which contains the logic required for sharing NFS or SMB. The following entry points exist in the vastly simplified libshare library: - sa_enable_share -- shares a dataset but may not commit the change - sa_disable_share -- unshares a dataset but may not commit the change - sa_is_shared -- determine if a dataset is shared - sa_commit_share -- notify NFS/SMB subsystem to commit the shares - sa_validate_shareopts -- determine if sharing options are valid The sa_commit_share entry point is provided as a performance enhancement and is not required. The sa_enable_share/sa_disable_share may commit the share as part of the implementation. Libshare provides a framework for both NFS and SMB but some operating systems may not fully support these protocols or all features of the protocol. NFS Operation: For linux, libshare updates /etc/exports.d/zfs.exports to add and remove shares and then commits the changes by invoking 'exportfs -r'. This file, is automatically read by the kernel NFS implementation which makes for better integration with the NFS systemd service. For FreeBSD, libshare updates /etc/zfs/exports to add and remove shares and then commits the changes by sending a SIGHUP to mountd. SMB Operation: For linux, libshare adds and removes files in /var/lib/samba/usershares by calling the 'net' command directly. There is no need to commit the changes. FreeBSD does not support SMB. == Performance Results To test sharing performance we created a pool with an increasing number of datasets and invoked various zfs actions that would enable and disable sharing. The performance testing was limited to NFS sharing. The following tests were performed on an 8 vCPU system with 128GB and a pool comprised of 4 50GB SSDs: Scale testing: - Share all filesystems in parallel -- zfs sharenfs=on <dataset> & - Unshare all filesystems in parallel -- zfs sharenfs=off <dataset> & Functional testing: - share each filesystem serially -- zfs share -a - unshare each filesystem serially -- zfs unshare -a - reset sharenfs property and unshare -- zfs inherit -r sharenfs <pool> For 'zfs sharenfs=on' scale testing we saw an average reduction in time of 89.43% and for 'zfs sharenfs=off' we saw an average reduction in time of 83.36%. Functional testing also shows a huge improvement: - zfs share -- 97.97% reduction in time - zfs unshare -- 96.47% reduction in time - zfs inhert -r sharenfs -- 99.01% reduction in time Reviewed-by: Matt Ahrens <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Reviewed-by: Ryan Moeller <[email protected]> Reviewed-by: Bryant G.

* Add device rebuild featureBrian Behlendorf2020-07-031-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The device_rebuild feature enables sequential reconstruction when resilvering. Mirror vdevs can be rebuilt in LBA order which may more quickly restore redundancy depending on the pools average block size, overall fragmentation and the performance characteristics of the devices. However, block checksums cannot be verified as part of the rebuild thus a scrub is automatically started after the sequential resilver completes. The new '-s' option has been added to the `zpool attach` and `zpool replace` command to request sequential reconstruction instead of healing reconstruction when resilvering. zpool attach -s <pool> <existing vdev> <new vdev> zpool replace -s <pool> <old vdev> <new vdev> The `zpool status` output has been updated to report the progress of sequential resilvering in the same way as healing resilvering. The one notable difference is that multiple sequential resilvers may be in progress as long as they're operating on different top-level vdevs. The `zpool wait -t resilver` command was extended to wait on sequential resilvers. From this perspective they are no different than healing resilvers. Sequential resilvers cannot be supported for RAIDZ, but are compatible with the dRAID feature being developed. As part of this change the resilver_restart_* tests were moved in to the functional/replacement directory. Additionally, the replacement tests were renamed and extended to verify both resilvering and rebuilding.

* Add block histogram to zdbRobert Novak2020-06-261-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The block histogram tracks the changes to psize, lsize and asize both in the count of the number of blocks (by blocksize) and the total length of all of the blocks for that blocksize. It also keeps a running total of the cumulative size of all of the blocks up to each size to help determine the size of caching SSDs to be added to zfs hardware deployments. The block history counts and lengths are summarized in bins which are powers of two. Even rows with counts of zero are printed. This change is accessed by specifying one of two options: zdb -bbb pool zdb -Pbbb pool The first version prints the table in fixed size columns.

* linux: add basic fallocate(mode=0/2) compatibilityadilger2020-06-181-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement semi-compatible functionality for mode=0 (preallocation) and mode=FALLOC_FL_KEEP_SIZE (preallocation beyond EOF) for ZPL. Since ZFS does COW and snapshots, preallocating blocks for a file cannot guarantee that writes to the file will not run out of space. Even if the first overwrite was guaranteed, it would not handle any later overwrite of blocks due to COW, so strict compliance is futile. Instead, make a best-effort check that at least enough free space is currently available in the pool (with a bit of margin), then create a sparse file of the requested size and continue on with life. This does not handle all cases (e.g. several fallocate() calls before writing into the files when the filesystem is nearly full), which would require a more complex mechanism to be implemented, probably based on a modified version of dmu_prealloc(), but is usable as-is. A new module option zfs_fallocate_reserve_percent is used to control the reserve margin for any single fallocate call. By default, this is 110% of the requested preallocation size, so an additional 10% of available space is reserved for overhead to allow the application a good chance of finishing the write when the fallocate() succeeds. If the heuristics of this basic fallocate implementation are not desirable, the old non-functional behavior of returning EOPNOTSUPP for calls can be restored by setting zfs_fallocate_reserve_percent=0. The parameter of zfs_statvfs() is changed to take an inode instead of a dentry, since no dentry is available in zfs_fallocate_common(). A few tests from @behlendorf cover basic fallocate functionality.

* File incorrectly zeroed when receiving incremental stream that toggles -LMatthew Ahrens2020-06-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Background: By increasing the recordsize property above the default of 128KB, a filesystem may have "large" blocks. By default, a send stream of such a filesystem does not contain large WRITE records, instead it decreases objects' block sizes to 128KB and splits the large blocks into 128KB blocks, allowing the large-block filesystem to be received by a system that does not support the `large_blocks` feature. A send stream generated by `zfs send -L` (or `--large-block`) preserves the large block size on the receiving system, by using large WRITE records. When receiving an incremental send stream for a filesystem with large blocks, if the send stream's -L flag was toggled, a bug is encountered in which the file's contents are incorrectly zeroed out. The contents of any blocks that were not modified by this send stream will be lost. "Toggled" means that the previous send used `-L`, but this incremental does not use `-L` (-L to no-L); or that the previous send did not use `-L`, but this incremental does use `-L` (no-L to -L). Changes: This commit addresses the problem with several changes to the semantics of zfs send/receive: 1. "-L to no-L" incrementals are rejected. If the previous send used `-L`, but this incremental does not use `-L`, the `zfs receive` will fail with this error message: incremental send stream requires -L (--large-block), to match previous receive. 2. "no-L to -L" incrementals are handled correctly, preserving the smaller (128KB) block size of any already-received files that used large blocks on the sending system but were split by `zfs send` without the `-L` flag. 3. A new send stream format flag is added, `SWITCH_TO_LARGE_BLOCKS`. This feature indicates that we can correctly handle "no-L to -L" incrementals. This flag is currently not set on any send streams. In the future, we intend for incremental send streams of snapshots that have large blocks to use `-L` by default, and these streams will also have the `SWITCH_TO_LARGE_BLOCKS` feature set. This ensures that streams from the default use of `zfs send` won't encounter the bug mentioned above, because they can't be received by software with the bug. Implementation notes: To facilitate accessing the ZPL's generation number, `zfs_space_delta_cb()` has been renamed to `zpl_get_file_info()` and restructured to fill in a struct with ZPL-specific info including owner and generation. In the "no-L to -L" case, if this is a compressed send stream (from `zfs send -cL`), large WRITE records that are being written to small (128KB) blocksize files need to be decompressed so that they can be written split up into multiple blocks. The zio pipeline will recompress each smaller block individually. A new test case, `send-L_toggle`, is added, which tests the "no-L to -L" case and verifies that we get an error for the "-L to no-L" case.

* Trim L2ARCGeorge Amanakis2020-06-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The l2arc_evict() function is responsible for evicting buffers which reference the next bytes of the L2ARC device to be overwritten. Teach this function to additionally TRIM that vdev space before it is overwritten if the device has been filled with data. This is done by vdev_trim_simple() which trims by issuing a new type of TRIM, TRIM_TYPE_SIMPLE. We also implement a "Trim Ahead" feature. It is a zfs module parameter, expressed in % of the current write size. This trims ahead of the current write size. A minimum of 64MB will be trimmed. The default is 0 which disables TRIM on L2ARC as it can put significant stress to underlying storage devices. To enable TRIM on L2ARC we set l2arc_trim_ahead > 0. We also implement TRIM of the whole cache device upon addition to a pool, pool creation or when the header of the device is invalid upon importing a pool or onlining a cache device. This is dependent on l2arc_trim_ahead > 0. TRIM of the whole device is done with TRIM_TYPE_MANUAL so that its status can be monitored by zpool status -t. We save the TRIM state for the whole device and the time of completion on-disk in the header, and restore these upon L2ARC rebuild so that zpool status -t can correctly report them. Whole device TRIM is done asynchronously so that the user can export of the pool or remove the cache device while it is trimming (ie if it is too slow). We do not TRIM the whole device if persistent L2ARC has been disabled by l2arc_rebuild_enabled = 0 because we may not want to lose all cached buffers (eg we may want to import the pool with l2arc_rebuild_enabled = 0 only once because of memory pressure). If persistent L2ARC has been disabled by setting the module parameter l2arc_rebuild_blocks_min_l2size to a value greater than the size of the cache device then the whole device is trimmed upon creation or import of a pool if l2arc_trim_ahead > 0.

* Resilver restarts unnecessarily when it encounters errorsJohn Poduska2020-05-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When a resilver finishes, vdev_dtl_reassess is called to hopefully excise DTL_MISSING (amongst other things). If there are errors during the resilver, they are tracked in DTL_SCRUB, as spelled out in the block comment in vdev.c. DTL_SCRUB is in-core only, so it can only be used if the pool was online for the whole resilver. This state is tracked with the spa_scrub_started flag, which only gets set when the scan is initialized. Unfortunately, this flag gets cleared right before vdev_dtl_reassess gets called, so if there are any errors during the scan, DTL_MISSING will never get excised and the resilver will just continually restart. This fix simply moves clearing that flag until after the call to vdev_dtl_reasses. In addition, if a pool is imported and already has scn_errors > 0, this change will restart the resilver immediately instead of doing the rest of the scan and then restarting it from the beginning. On the other hand, if scn_errors == 0 at import, then no errors have been encountered so far, so the spa_scrub_started flag can be safely set. A test has been added to verify that resilver does not restart when relevant DTL's are available.

| | | | | | | | | | | | | | | | | | | | | | | | | Deduplicated send streams (i.e. `zfs send -D` and `zfs receive` of such streams) are deprecated. Deduplicated send streams can be received by first converting them to non-deduplicated with the `zstream redup` command. This commit removes the code for sending and receiving deduplicated send streams. `zfs send -D` will now print a warning, ignore the `-D` flag, and generate a regular (non-deduplicated) send stream. `zfs receive` of a deduplicated send stream will print an error message and fail. The resulting code simplification (especially in the kernel's support for receiving dedup streams) should help enable future performance enhancements.

This can result in issues for redacted send/recv users who expect the deleted files to be redacted in the send streams, and not appear in their clones.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This feature allows copying existing bookmarks using zfs bookmark fs#target fs#newbookmark There are some niche use cases for such functionality, e.g. when using bookmarks as markers for replication progress. Copying redaction bookmarks produces a normal bookmark that cannot be used for redacted send (we are not duplicating the redaction object).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow a range of object identifiers to dump with -d. This may be useful when dumping a large dataset and you want to break it up into multiple phases, or to resume where a previous scan left off. Object type selection flags are supported to reduce the performance overhead of verbosely dumping unwanted objects, and to reduce the amount of post-processing work needed to filter out unwanted objects from zdb output. This change extends existing syntax in a backward-compatible way. That is, the base case of a range is to specify a single object identifier to dump. Ranges and object identifiers can be intermixed as command line parameters. Usage synopsis: Object ranges take the form <start>:<end>[:<flags>] start Starting object number end Ending object number, or -1 for no upper bound flags Optional flags to select object types: A All objects (this is the default) d ZFS directories f ZFS files m SPA space maps z ZAPs - Negate effect of next flag Examples: # Dump all file objects zdb -dd tank/fish 0:-1:f # Dump all file and directory objects zdb -dd tank/fish 0:-1:fd # Dump all types except file and directory objects zdb -dd tank/fish 0:-1:A-f-d # Dump object IDs in a specific range zdb -dd tank/fish 1000:2000 Reviewed-by: Brian Behlendorf <[email protected]> Reviewed-by: Ryan Moeller <[email protected]> Reviewed-by: Paul Zuchowski <[email protected]> Signed-off-by: Ned Bass <[email protected]> Closes #9832
