* MFC r305323: MFV r302991: 6950 ARC should cache compressed datamav2016-10-141-1/+1

The uncompressed data should be short-lived allowing the ARC to cache a much large r amount of data. The DMU would also maintain a smaller cache of uncompressed blocks to minimize the impact of decompressing frequently accessed blocks.

* MFC r277300 (by smh): Mechanically convert cddl sun #ifdef's to illumosmav2016-03-201-3/+3
| | | | | | | | | Since the upstream for cddl code is now illumos not sun, mechanically convert all sun #ifdef's to illumos #ifdef's which have been used in all newer code for some time. Also do a manual pass to correct the use if #ifdef comments as per style(9) as well as few uses of #if defined(__FreeBSD__) vs #ifndef illumos.
* MFC r287702: 5987 zfs prefetch code needs workmav2015-10-031-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rewrite the ZFS prefetch code to detect only forward, sequential streams. The following kstats have been added: kstat.zfs.misc.arcstats.sync_wait_for_async How many sync reads have waited for async read to complete. (less is better) kstat.zfs.misc.arcstats.demand_hit_predictive_prefetch How many demand read didn't have to wait for I/O because of predictive prefetch. (more is better) zfetch kstats have been similified to hits, misses, and max_streams, with max_streams representing times when we were not able to create new stream because we already have the maximum number of sequences for a file. The sysctl variable/loader tunable vfs.zfs.zfetch.block_cap have been replaced by vfs.zfs.zfetch.max_distance, which controls maximum bytes to prefetch per stream. illumos/illumos-gate@cf6106c8a0d6598b045811f9650d66e07eb332af Illumos ZFS issues: 5987 zfs prefetch code needs work https://www.illumos.org/issues/5987

| | | | | | | | | | | | | | | | 5925 zfs receive -o origin= Reviewed by: Prakash Surya <prakash.surya@delphix.com> Reviewed by: Matthew Ahrens <mahrens@delphix.com> Author: Paul Dagnelie <pcd@delphix.com> While running 'zfs recv' we noticed that every 128th 8K block required a read. We were seeing that restore_write() was calling dmu_tx_hold_write() and the indirect block was not cached. We should prefetch upcoming indirect blocks to avoid having to go to disk and blocking the restore_write(). Allow an incremental send stream to be received as a clone, even if the stream does not mark it as a clone.

It is actually making slow progress at the file deletion, but other operations (administrative and writes via the data path) "hang" until the file removal completes, which can take a long time if the file has many blocks. The deletion (or most of it) happens in a single txg, and the sync thread spends most of its time reading indirect blocks...

| | | | | | | | | | | | | | | | | | | | | | | | As of r270383, the dbuf_compare comparator compares the dbuf attributes in the following order: db_level (indirect level) db_blkid (block number) db_state (current state) the address of the element Because db_state is being considered before the element's state, changing of db_state would affect balancedness of the AVL tree, even when the address of element compares differently. For instance, in dbuf_create, db_state may be altered after the node is inserted into the AVL tree and may break AVL tree balancedness. Instead of using db_state as a comparision critera (introduced in r270383), consider it only when we are doing a lookup, that is one of the two dbuf pointers contains DB_SEARCH.

| | | | | | | | | | | | | | | | | | | | | ZFS large block support. The default recordsize remains at 128KB. A new tunable/sysctl variable, vfs.zfs.max_recordsize is added to allow adjusting the permitted maximum record size, or zfs_max_recordsize, with a default of 1MB. ZFS will not allow setting recordsize greater than zfs_max_recordsize as a safety belt, because larger recordsize means greater read and write latency and more memory usage. Please note that booting from datasets that have recordsize greater than 128KB is not supported (but it's Okay to enable the feature on the pool). Limited safety belt is provided for mounted root filesystem but use caution when using a larger value. Illumos issue: 5027 zfs large block support

| | | | | | | | | | | | | | | | | | | Correctly report hole at end of file. When asked to find a hole, the DMU sees that there are no holes in the object, and returns ESRCH. The ZPL interprets this as "no holes before the end of the file", and therefore inserts the "virtual hole" at the end of the file. Because DMU and ZPL have different ideas of where the end of an object/file is, we will end up returning the end of file, which is generally larger, instead of returning the end of object. The fix is to handle the "virtual hole" in the DMU. If no hole is found, the DMU will return a hole at the end of the file, rather than an error.

Huge performance improvements mostly for random read of mostly static content. - slog Allow to use additional disks for ZFS Intent Log to speed up operations like fsync(2). - vfs.zfs.super_owner Allows regular users to perform privileged operations on files stored on ZFS file systems owned by him. Very careful with this one. - chflags(2) Not all the flags are supported. This still needs work. - ZFSBoot Support to boot off of ZFS pool. Not finished, AFAIK. Submitted by: dfr - Snapshot properties - New failure modes Before if write requested failed, system paniced. Now one can select from one of three failure modes: - panic - panic on write error - wait - wait for disk to reappear - continue - serve read requests if possible, block write requests - Refquota, refreservation properties Just quota and reservation properties, but don't count space consumed by children file systems, clones and snapshots. - Sparse volumes ZVOLs that don't reserve space in the pool. - External attributes Compatible with extattr(2). - NFSv4-ACLs Not sure about the status, might not be complete yet. Submitted by: trasz - Creation-time properties - Regression tests for zpool(8) command. Obtained from: OpenSolaris
* - Add missing lock destruction and remove duplicate initializations.pjd2007-05-061-1/+0
| | | | | | With this change it is possible to unload zfs.ko module from WITNESS-enabled kernel. - Remove bogus comment.
* Please welcome ZFS - The last word in file systems.pjd2007-04-061-0/+1370
