| | | | | | | | | | | | | | | When calculating mg_aliquot alike to #12046 use number of unique data disks in the vdev, not the total number of children vdev. Increase default value of the tunable from 512KB to 1MB to compensate. Before this change each disk in striped pool was getting 512KB of sequential data, in 2-wide mirror -- 1MB, in 3-wide RAIDZ1 -- 768KB. After this change in all the cases each disk should get 1MB.

* Default zfs_max_recordsize to 16MRich Ercolani2022-04-281-3/+3
| | | | | | | | | | | | | | | | | | | | Increase the default allowed maximum recordsize from 1M to 16M. As described in the zfs(4) man page, there are significant costs which need to be considered before using very large blocks. However, there are scenarios where they make good sense and it should no longer be necessary to artificially restrict their use behind a module option. Note that for 32-bit platforms we continue to leave this restriction in place due to the limited virtual address space available (256-512MB). On these systems only a handful of blocks could be cached at any one time severely impacting performance and potentially stability.

* Improve log spacemap load timeAlexander Motin2022-04-261-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous flushing algorithm limited only total number of log blocks to the minimum of 256K and 4x number of metaslabs in the pool. As result, system with 1500 disks with 1000 metaslabs each, touching several new metaslabs each TXG could grow spacemap log to huge size without much benefits. We've observed one of such systems importing pool for about 45 minutes. This patch improves the situation from five sides: - By limiting maximum period for each metaslab to be flushed to 1000 TXGs, that effectively limits maximum number of per-TXG spacemap logs to load to the same number. - By making flushing more smooth via accounting number of metaslabs that were touched after the last flush and actually need another flush, not just ms_unflushed_txg bump. - By applying zfs_unflushed_log_block_pct to the number of metaslabs that were touched after the last flush, not all metaslabs in the pool. - By aggressively prefetching per-TXG spacemap logs up to 16 TXGs in advance, making log spacemap load process for wide HDD pool CPU-bound, accelerating it by many times. - By reducing zfs_unflushed_log_block_max from 256K to 128K, reducing single-threaded by nature log processing time from ~10 to ~5 minutes. As further optimization we could skip bumping ms_unflushed_txg for metaslabs not touched since the last flush, but that would be an incompatible change, requiring new pool feature.

* Improve zpool status output, list all affected datasetsGeorge Amanakis2022-04-252-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, determining which datasets are affected by corruption is a manual process. The primary difficulty in reporting the list of affected snapshots is that since the error was initially found, the snapshot where the error originally occurred in, may have been deleted. To solve this issue, we add the ID of the head dataset of the original snapshot which the error was detected in, to the stored error report. Then any time a filesystem is deleted, the errors associated with it are deleted as well. Any time a clone promote occurs, we modify reports associated with the original head to refer to the new head. The stored error reports are identified by this head ID, the birth time of the block which the error occurred in, as well as some information about the error itself are also stored. Once this information is stored, we can find the set of datasets affected by an error by walking back the list of snapshots in the given head until we find one with the appropriate birth txg, and then traverse through the snapshots of the clone family, terminating a branch if the block was replaced in a given snapshot. Then we report this information back to libzfs, and to the zpool status command, where it is displayed as follows: pool: test state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-8A scan: scrub repaired 0B in 00:00:00 with 800 errors on Fri Dec 3 08:27:57 2021 config: NAME STATE READ WRITE CKSUM test ONLINE 0 0 0 sdb ONLINE 0 0 1.58K errors: Permanent errors have been detected in the following files: test@1:/test.0.0 /test/test.0.0 /test/1clone/test.0.0 A new feature flag is introduced to mark the presence of this change, as well as promotion and backwards compatibility logic. This is an updated version of #9175. Rebase required fixing the tests, updating the ABI of libzfs, updating the man pages, fixing bugs, fixing the error returns, and updating the old on-disk error logs to the new format when activating the feature.
