* OpenZFS 7968 - multi-threaded spa_sync()Matthew Ahrens2017-03-206-12/+16
| | | | | | | | | | | | | | | | | | | | | | | Reviewed by: Pavel Zakharov <[email protected]> Reviewed by: Brad Lewis <[email protected]> Reviewed by: Saso Kiselkov <[email protected]> Reviewed by: Brian Behlendorf <[email protected]> Ported-by: Matthew Ahrens <[email protected]> spa_sync() iterates over all the dirty dnodes and processes each of them by calling dnode_sync(). If there are many dirty dnodes (e.g. because we created or removed a lot of files), the single thread of spa_sync() calling dnode_sync() can become a bottleneck. Additionally, if many dnodes are dirtied concurrently in open context (e.g. due to concurrent file creation), the os_lock will experience lock contention via dnode_setdirty(). The solution is to track dirty dnodes on a multilist_t, and for spa_sync() to use separate threads to process each of the sublists in the multilist.

* Restructure mount option handlingBrian Behlendorf2017-03-101-26/+34
| | | | | | | | | | | | | | | | | | | | | | Restructure the handling of mount options to be consistent with upstream OpenZFS. This required making the following changes. - The zfs_mntopts_t was renamed vfs_t and adjusted to provide the minimal needed functionality. This includes a pointer back to the associated zfsvfs_t. Plus it made it possible to revert zfs_register_callbacks() and zfsvfs_create() back to their original prototypes. - A zfs_mnt_t structure was added for the sole purpose of providing a structure to pass the osname and raw mount pointer to zfs_domount() without having to copy them. - Mount option parsing was moved down from the zpl_* wrapper functions in to the zfs_* functions. This allowed for the code to be simplied and it's where similar functionality appears on other platforms. Signed-off-by: Brian Behlendorf <[email protected]>
* Rename zfs_* functionsBrian Behlendorf2017-03-102-16/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Several functions were renamed when ZFS was originally ported to Linux. Revert the code to the original names to minimize the delta with upstream OpenZFS. zfs_sb_teardown -> zfsvfs_teardown zfs_sb_create -> zfsvfs_create zfs_sb_setup -> zfsvfs_setup zfs_sb_free -> zfsvfs_free get_zfs_sb -> getzfsvfs zfs_sb_hold -> zfsvfs_hold zfs_sb_rele -> zfsvfs_rele zfs_sb_prune_aliases -> zfs_prune_aliases (Linux-only) zfs_sb_prune -> zfs_prune (Linux only) Align the zfs_vnops.h and zfs_vfsops.h with upstream as much as possible. Several prototypes were removed and those that remain were reordered. Move the EXPORT_SYMBOL lines to the end of the source files for consistency with the other source files.

* Fix nfs snapdir automountChunwei Chen2017-03-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | The current implementation for allowing nfs to access snapdir is very buggy. It uses a special fh for snapdirs, such that the next time nfsd does fh_to_dentry, it actually returns the root inode inside the snapshot. So nfsd never knows it cross a mountpoint. The problem is that nfsd will not hold a reference on the vfsmount of the snapshot. This cause auto unmounter to unmount the snapshot even though nfs is still holding dentries in it. To fix this, we return the inode for the snapdirs themselves. However, we also trigger automount upon fh_to_dentry, and return ESTALE so nfsd will revalidate and see the mountpoint and do crossmnt. Because nfsd will now be aware that these are different filesystems users must add crossmnt to their export options to access snapshot directories.

* OpenZFS 7793 - ztest fails assertion in dmu_tx_willuse_spaceBrian Behlendorf2017-03-0710-61/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* OpenZFS 7743 - per-vdev-zaps init path for upgradeDon Brady2017-01-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Authored by: Paul Dagnelie <[email protected]> Reviewed by: Matt Ahrens <[email protected]> Reviewed by: Pavel Zakharov <[email protected]> Reviewed by: George Wilson <[email protected]> Reviewed by: Don Brady <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Reviewed-by: Joe Stein <[email protected]> Ported-by: Don Brady <[email protected]> When loading a pool that had been created before the existance of per-vdev zaps, on a system that knows about per-vdev zaps, the per-vdev zaps will not be allocated and initialized. This appears to be because the logic that would have done so, in spa_sync_config_object(), is not reached under normal operation. It is only reached if spa_config_dirty_list is non-empty. The fix is to add another `AVZ_ACTION_` enum that will allow this code to be reached when we detect that we're loading an old pool, even when there are no dirty configs.

* OpenZFS 7303 - dynamic metaslab selectionDon Brady2017-01-125-14/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | This change introduces a new weighting algorithm to improve metaslab selection. The new weighting algorithm relies on the SPACEMAP_HISTOGRAM feature. As a result, the metaslab weight now encodes the type of weighting algorithm used (size-based vs segment-based). Porting Notes: The metaslab allocation tracing code is conditionally removed on linux (dependent on mdb debugger).

* Use a dedicated taskq for vdev_fileChunwei Chen2016-12-211-0/+3
| | | | | | | | | | | | | | | | | The introduction of parallel zvol prefetch causes deadlock when using vdev_file. spa_async->(spa_namespace_lock)->txg_wait_synced->(wait for txg_sync) txg_sync->zio_wait->(wait for vdev_file_io_fsync on system_taskq) zvol_prefetch_minors_impl (on system_taskq)->spa_open_common->(wait for spa_namespace_lock) We fix this by using dedicated taskq for vdev_file. This same change was originally made in commit bc25c93 but reverted in commit aa9af22 when dynamic taskqs were added.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | It was observed that even when the txg history is disabled by setting `zfs_txg_history=0` the txg_sync thread still fetches the vdev stats unnecessarily. This patch refactors the code such that vdev_get_stats() is no longer called when `zfs_txg_history=0`. And it further reduces the differences between upstream and the ZoL txg_sync_thread() function.
