* Update deadman operation to better align with upstream OpenZFSTim Chase2017-01-311-1/+15
| | | | | | | | | | | | | | | | | | | | | | | The deadman in ZoL didn't behave quite as it did in upstream OpenZFS. In addition to the 2 purposes for which OpenZFS used the zfs_deadman_synctime_ms parameter, ZoL also used it to determine how frequently the deadman would fire once it has been triggered. This patch adds the zfs_deadman_checktime_ms parameter to control how frequently the subsequent checks are performed. The deadman is now disabled for suspended pools. As had been the case, unlike upstream OpenZFS, ZoL will not panic when a hung IO is detected. The module parameter documentation has been upated to include the new parameter and to better describe the operation of the deadmen.

* Fix suspend Godfather I/Os io_reexecute bitsBrian Behlendorf2017-01-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | After resuming a pool the godfather zio could have both the ZIO_REEXECUTE_NOW and ZIO_REEXECUTE_SUSPEND bits set. This can occur if some child zios set ZIO_REEXECUTE_NOW while other set ZIO_REEXECUTE_SUSPEND. The godfather zio can inherit both flags in zio_notify_parent(). The child zios which assigned the ZIO_REEXECUTE_SUSPEND flag will be removed from the godfather's child list and added to the spa->spa_suspend_zio_root child list. While child zios with the ZIO_REEXECUTE_NOW bit set remain being monitored by the godfather zio. When the godfather zio executes zio_done() the presence of the ZIO_REEXECUTE_SUSPEND bit results in all io_reexecute being cleared. These child zios will then not be re-executed and instead will be destroyed and lost. The most straight forward way to address this situation is to only clear the ZIO_REEXECUTE_SUSPEND bit and leave the ZIO_REEXECUTE_NOW bit set.

* OpenZFS 7606 - dmu_objset_find_dp() takes a long time while importing poolGeorge Melikov2017-01-261-4/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When importing a pool with a large number of filesystems within the same parent filesystem, we see that dmu_objset_find_dp() takes a long time. It is called from 3 places: spa_check_logs(), spa_ld_claim_log_blocks(), and spa_load_verify(). There are several ways to improve performance here: 1. We don't really need to do spa_check_logs() or spa_ld_claim_log_blocks() if the pool was closed cleanly. 2. spa_load_verify() uses dmu_objset_find_dp() to check that no datasets have too long of names. 3. dmu_objset_find_dp() is slow because it's doing zap_value_search() (which is O(N sibling datasets)) to determine the name of each dsl_dir when it's opened. In this case we actually know the name when we are opening it, so we can provide it and avoid the lookup. This change implements fix #3 from the above list; i.e. make dmu_objset_find_dp() provide the name of the dataset so that we don't have to search for it.

* Suspend/resume zvol for recv and rollbackChunwei Chen2017-01-193-40/+163
| | | | | | | | | | | | | | | | When doing recv and rollback, dsl_dataset_clone_swap_sync_impl will be called to swap out the ds_objset and do dmu_objset_evict on the old one. However, currently zv->zv_objset will not be swapped out accordingly, so if anyone currently holds a fd on the zvol, we risk hitting a use-after-free. We fix this by introducing the suspend and resume mechanism of zsb to zv. Before recv or rollback, we use zvol_suspend to block all access to zv_objset and shut it down. After the recv or rollback, we use zvol_resume to swap in zv_objset with the new ds_objset and unblock the access.

* OpenZFS 7743 - per-vdev-zaps init path for upgradeDon Brady2017-01-131-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 Brady2017-01-125-204/+864
| | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* 4.10 compat - BIO flag changes and othersTim Chase2016-12-302-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | [bio] The req_op enum was changed to req_opf. Update the "Linux 4.8 API" autotools checks to use an int to determine whether the various REQ_OP values are defined. This should work properly on kernels >= 4.8. [bio] bio_set_op_attrs() is now an inline function and can't be detected with #ifdef. Add a configure check to determine whether bio_set_op_attrs() is defined. Move the local definition of it from vdev_disk.c to blkdev_compat.h for consistency with other related compability shims. [bio] The read/write flags and their modifiers, including WRITE_FLUSH, WRITE_FUA and WRITE_FLUSH_FUA have been removed from fs.h. Add the new bio_set_flush() compatibility wrapper to replace VDEV_WRITE_FLUSH_FUA and set the flags appropriately for each supported kernel version. [vfs] The generic_readlink() function has been made static. If .readlink in inode_operations is NULL, generic_readlink() is used. [zol typo] Completely unrelated to 4.10 compat, fix a typo in the check for REQ_OP_SECURE_ERASE so that the proper macro is defined: s/HAVE_REQ_OP_SECURE_DISCARD/HAVE_REQ_OP_SECURE_ERASE/ Reviewed-by: Brian Behlendorf <[email protected]> Reviewed-by: Chunwei Chen <[email protected]> Signed-off-by: Tim Chase <[email protected]> Closes #5499

| | | | | | | | | | | | | | | | | 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.
