* Deprecate deduplicated send streamsMatthew Ahrens2020-03-185-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dedup send can only deduplicate over the set of blocks in the send command being invoked, and it does not take advantage of the dedup table to do so. This is a very common misconception among not only users, but developers, and makes the feature seem more useful than it is. As a result, many users are using the feature but not getting any benefit from it. Dedup send requires a nontrivial expenditure of memory and CPU to operate, especially if the dataset(s) being sent is (are) not already using a dedup-strength checksum. Dedup send adds developer burden. It expands the test matrix when developing new features, causing bugs in released code, and delaying development efforts by forcing more testing to be done. As a result, we are deprecating the use of `zfs send -D` and receiving of such streams. This change adds a warning to the man page, and also prints the warning whenever dedup send or receive are used. In a future release, we plan to: 1. remove the kernel code for generating deduplicated streams 2. make `zfs send -D` generate regular, non-deduplicated streams 3. remove the kernel code for receiving deduplicated streams 4. make `zfs receive` of deduplicated streams process them in userland to "re-duplicate" them, so that they can still be received.

* Improve zfs receive performance by batching writesMatthew Ahrens2020-03-162-51/+182
| | | | | | | | | | | | | | | | | | | | | | | | | For each WRITE record in the stream, `zfs receive` creates a DMU transaction (`dmu_tx_create()`) and writes this block's data into the object. If per-block overheads (as opposed to per-byte overheads) dominate performance (as is often the case with small recordsize), the per-dmu-transaction overheads can be significant. For example, in some workloads the `receieve_writer` thread is 100% on CPU, and more than half of its CPU time is in these per-tx routines (e.g. dmu_tx_hold_write, dmu_tx_assign, dmu_tx_commit). To improve performance of `zfs receive`, this commit batches WRITE records which are to nearby offsets of the same object, and uses one DMU transaction to write them all. By default the batch size is 1MB, which for recordsize=8K reduces the number of DMU transactions by 128x for full send streams (incrementals will depend on how "clumpy" the changed blocks are). This commit improves the performance of `dd if=stream | zfs recv` from 78,800 blocks/sec to 98,100 blocks/sec (25% improvement).

* dmu_objset_from_ds must be called with dp_config_rwlock heldMatthew Ahrens2020-03-127-115/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The normal lock order is that the dp_config_rwlock must be held before the ds_opening_lock. For example, dmu_objset_hold() does this. However, dmu_objset_open_impl() is called with the ds_opening_lock held, and if the dp_config_rwlock is not already held, it will attempt to acquire it. This may lead to deadlock, since the lock order is reversed. Looking at all the callers of dmu_objset_open_impl() (which is principally the callers of dmu_objset_from_ds()), almost all callers already have the dp_config_rwlock. However, there are a few places in the send and receive code paths that do not. For example: dsl_crypto_populate_key_nvlist, send_cb, dmu_recv_stream, receive_write_byref, redact_traverse_thread. This commit resolves the problem by requiring all callers ot dmu_objset_from_ds() to hold the dp_config_rwlock. In most cases, the code has been restructured such that we call dmu_objset_from_ds() earlier on in the send and receive processes, when we already have the dp_config_rwlock, and save the objset_t until we need it in the middle of the send or receive (similar to what we already do with the dsl_dataset_t). Thus we do not need to acquire the dp_config_rwlock in many new places. I also cleaned up code in dmu_redact_snap() and send_traverse_thread().

| | | | | | | | | | | | | | | | | | | | | | | dnode_special_close() waits for the refcount of dn_holds to go to zero without holding the dn_mtx. dnode_rele_and_unlock() does the final remove to dn_holds with dn_mtx being held: refs = zfs_refcount_remove(&dn->dn_holds, tag); mutex_exit(&dn->dn_mtx); So, there is a race condition after the remove until dn_mtx is dropped. During that time, dnode_destroy() can get called, which ends up in dnode_dest() calling mutex_destroy() and a panic since the lock is still held. This change adds a condvar to wait for the final dnode_rele_and_unlock() to release the dn_mtx before calling dnode_destroy().

* Improve zfs send performance by bypassing the ARCMatthew Ahrens2020-03-104-151/+235
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When doing a zfs send on a dataset with small recordsize (e.g. 8K), performance is dominated by the per-block overheads. This is especially true with `zfs send --compressed`, which further reduces the amount of data sent, for the same number of blocks. Several threads are involved, but the limiting factor is the `send_prefetch` thread, which is 100% on CPU. The main job of the `send_prefetch` thread is to issue zio's for the data that will be needed by the main thread. It does this by calling `arc_read(ARC_FLAG_PREFETCH)`. This has an immediate cost of creating an arc_hdr, which takes around 14% of one CPU. It also induces later costs by other threads: * Since the data was only prefetched, dmu_send()->dmu_dump_write() will need to call arc_read() again to get the data. This will have to look up the arc_hdr in the hash table and copy the data from the scatter ABD in the arc_hdr to a linear ABD in arc_buf. This takes 27% of one CPU. * dmu_dump_write() needs to arc_buf_destroy() This takes 11% of one CPU. * arc_adjust() will need to evict this arc_hdr, taking about 50% of one CPU. All of these costs can be avoided by bypassing the ARC if the data is not already cached. This commit changes `zfs send` to check for the data in the ARC, and if it is not found then we directly call `zio_read()`, reading the data into a linear ABD which is used by dmu_dump_write() directly. The performance improvement is best expressed in terms of how many blocks can be processed by `zfs send` in one second. This change increases the metric by 50%, from ~100,000 to ~150,000. When the amount of data per block is small (e.g. 2KB), there is a corresponding reduction in the elapsed time of `zfs send >/dev/null` (from 86 minutes to 58 minutes in this test case). In addition to improving the performance of `zfs send`, this change makes `zfs send` not pollute the ARC cache. In most cases the data will not be reused, so this allows us to keep caching useful data in the MRU (hit-once) part of the ARC.

* ZTS: Speed up write_dirs cleanupBrian Behlendorf2020-03-042-10/+4
| | | | | | | | | | | | | The write_dirs tests fill a filesystem with a bunch of files until it is full. In cleanup the files are truncated and removed individually. These tests already take a while to run. It is quicker and easier to destroy the whole dataset and create a new one to replace it in the cleanup functions.

* ZTS: Add missing quotesBrian Behlendorf2020-03-042-2/+2
| | | | | | | | | | | | | | `default_setup` takes a disk list as the first argument and has optional additional arguments that control secondary functionality. A couple of test setups mistakenly call `default_setup $DISKS`. Add quotes so the second and subsequent disks are correctly included in the pool as vdevs rather than triggering unwanted behavior from `default_setup`.

* ZTS: Test the correct filesystem_limits behaviorBrian Behlendorf2020-03-045-17/+126
| | | | | | | | | | | | | | | | | | | | See issue #8226: Property filesystem_limit does not work as documented There have been previous attempts to fix the behavior on Linux, but so far the issue is still open. See PRs #8228, #8280. The existing tests pass for the incorrect behavior. This is a problem on FreeBSD; we are failing the tests because we implement the feature correctly. I have adapted the tests based on the work by @loli10k in #8280 and extended the changes to fix the snapshot_limit test as well. Linux now fails these tests, so entries linking to the issue have been added to the "maybe" group in zts-report.py.

* Add trim support to zpool waitBrian Behlendorf2020-03-0417-73/+347
| | | | | | | | | | | | Manual trims fall into the category of long-running pool activities which people might want to wait synchronously for. This change adds support to 'zpool wait' for waiting for manual trim operations to complete. It also adds a '-w' flag to 'zpool trim' which can be used to turn 'zpool trim' into a synchronous operation.

* Improve performance of zio_taskq_memberMatthew Ahrens2020-03-035-2/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | __zio_execute() calls zio_taskq_member() to determine if we are running in a zio interrupt taskq, in which case we may need to switch to processing this zio in a zio issue taskq. The call to zio_taskq_member() can become a performance bottleneck when we are processing a high rate of zio's. zio_taskq_member() calls taskq_member() on each of the zio interrupt taskqs, of which there are 21. This is slow because each call to taskq_member() does tsd_get(taskq_tsd), which on Linux is relatively slow. This commit improves the performance of zio_taskq_member() by having it cache the value of tsd_get(taskq_tsd), reducing the number of those calls to 1/21th of the current behavior. In a test case running `zfs send -c >/dev/null` of a filesystem with small blocks (average 2.5KB/block), zio_taskq_member() was using 6.7% of one CPU, and with this change it is reduced to 1.3%. Overall time to perform the `zfs send` reduced by 10% (~150,000 block/sec to ~165,000 blocks/sec).

* ZTS: Provide for nested cleanup routinesRyan Moeller2020-03-032-5/+25
| | | | | | | | | | | | | | | | | | | | | | | Shared test library functions lack a simple way to ensure proper cleanup in the event of a failure. The `log_onexit` cleanup pattern cannot be used in library functions because it uses one global variable to store the cleanup command. An example of where this is a serious issue is when a tunable that artifically stalls kernel progress gets activated and then some check fails. Unless the caller knows about the tunable and sets it back, the system will be left in a bad state. To solve this problem, turn the global cleanup variable into a stack. Provide push and pop functions to add additional cleanup steps and remove them after it is safe again. The first use of this new functionality is in attempt_during_removal, which sets REMOVAL_SUSPEND_PROGRESS.
