* Add line info and SET_ERROR() to ZFS debug logNed Bass2017-07-256-102/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Redefine the SET_ERROR macro in terms of __dprintf() so the error return codes get logged as both tracepoint events (if tracepoints are enabled) and as ZFS debug log entries. This also allows us to use the same definition of SET_ERROR() in kernel and user space. Define a new debug flag ZFS_DEBUG_SET_ERROR=512 that may be bitwise or'd into zfs_flags. Setting this flag enables both dprintf() and SET_ERROR() messages in the debug log. That is, setting ZFS_DEBUG_SET_ERROR and ZFS_DEBUG_DPRINTF|ZFS_DEBUG_SET_ERROR are equivalent (this was done for sake of simplicity). Leaving ZFS_DEBUG_SET_ERROR unset suppresses the SET_ERROR() messages which helps avoid cluttering up the logs. To enable SET_ERROR() logging, run: echo 1 > /sys/module/zfs/parameters/zfs_dbgmsg_enable echo 512 > /sys/module/zfs/parameters/zfs_flags Remove the zfs_set_error_class tracepoints event class since SET_ERROR() now uses __dprintf(). This sacrifices a bit of granularity when selecting individual tracepoint events to enable but it makes the code simpler. Include file, function, and line number information in debug log entries. The information is now added to the message buffer in __dprintf() and as a result the zfs_dprintf_class tracepoints event class was changed from a 4 parameter interface to a single parameter.

* Some additional send stream validity checkingNed Bass2017-07-252-10/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | Check in the DMU whether an object record in a send stream being received contains an unsupported dnode slot count, and return an error if it does. Failure to catch an unsupported dnode slot count would result in a panic when the SPA attempts to increment the reference count for the large_dnode feature and the pool has the feature disabled. This is not normally an issue for a well-formed send stream which would have the DMU_BACKUP_FEATURE_LARGE_DNODE flag set if it contains large dnodes, so it will be rejected as unsupported if the required feature is disabled. This change adds a missing object record field validation. Add missing stream feature flag checks in dmu_recv_resume_begin_check(). Consolidate repetitive comment blocks in dmu_recv_begin_check(). Update zstreamdump to print the dnode slot count (dn_slots) for an object record when running in verbose mode.

| | | | | | | | | | | | | | | | | 'zpool clear' should be able to resume I/O on suspended, but otherwise healthy, pools. 4a283c7 accidentally introduced a new code path where we call txg_wait_synced() on the suspended pool before we had the chance to resume I/O via zio_resume(): this results in the 'zpool clear' command hanging indefinitely, waiting for a TXG that cannot be synced.

* Add callback for zfs_multihost_intervalOlaf Faaland2017-07-257-2/+164
| | | | | | | | | | | | | | | | | | | | | | | | | | Add a callback to wake all running mmp threads when zfs_multihost_interval is changed. This is necessary when the interval is changed from a very large value to a significantly lower one, while pools are imported that have the multihost property enabled. Without this commit, the mmp thread does not wake up and detect the new interval until after it has waited the old multihost interval time. A user monitoring mmp writes via the provided kstat would be led to believe that the changed setting did not work. Added a test in the ZTS under mmp to verify the new functionality is working. Added a test to ztest which starts and stops mmp threads, and calls into the code to signal sleeping mmp threads, to test for deadlocks or similar locking issues.

* Add zgenhostid utility scriptOlaf Faaland2017-07-2514-11/+151
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Turning the multihost property on requires that a hostid be set to allow ZFS to determine when a foreign system is attemping to import a pool. The error message instructing the user to set a hostid refers to genhostid(1). Genhostid(1) is not available on SUSE Linux. This commit adds a script modeled after genhostid(1) for those users. Zgenhostid checks for an /etc/hostid file; if it does not exist, it creates one and stores a value. If the user has provided a hostid as an argument, that value is used. Otherwise, a random hostid is generated and stored. This differs from the CENTOS 6/7 versions of genhostid, which overwrite the /etc/hostid file even though their manpages state otherwise. A man page for zgenhostid is added. The one for genhostid is in (1), but I put zgenhostid in (8) because I believe it's more appropriate. The mmp tests are modified to use zgenhostid to set the hostid instead of using the spl_hostid module parameter. zgenhostid will not replace an existing /etc/hostid file, so new mmp_clear_hostid calls are required.

Since the I/Os are executed via map_nowait(), the done function is the only place where we know the write has completed. Since SCL_STATE is taken as reader, overlapping I/Os do not create a deadlock.

* Fix vdev_probe() call outside SCL_STATE_ALL lockBrian Behlendorf2017-07-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an IO fails then zio_vdev_io_done() can call vdev_probe() to determine the health of the vdev. This is safe as long as the original zio was submitted with zio_wait() and holds the SCL_STATE_ALL lock over the operation. If zio_no_wait() was used then the done callback will submit the probe IO outside the SCL_STATE_ALL lock and hit this ASSERT in zio_create() ASSERT(!vd || spa_config_held(spa, SCL_STATE_ALL, RW_READER)); Resolve the issue by only allowing vdev_probe() to be called when there's a waiter indicating the caller is using zio_wait(). This assumes that caller is still holding SCL_STATE_ALL. This issue isn't MMP specific but was surfaced when testing.

When enabled a new thread writes uberblocks to the last slot in each label, at a set frequency, to indicate to other hosts the pool is actively imported. These uberblocks are the last synced uberblock with an updated timestamp. Property defaults to off. During tryimport, find the "best" uberblock (newest txg and timestamp) repeatedly, checking for change in the found uberblock. Include the results of the activity test in the config returned by tryimport. These results are reported to user in "zpool import". Allow the user to control the period between MMP writes, and the duration of the activity test on import, via a new module parameter zfs_multihost_interval. The period is specified in milliseconds. The activity test duration is calculated from this value, and from the mmp_delay in the "best" uberblock found initially. Add a kstat interface to export statistics about Multiple Modifier Protection (MMP) updates. Include the last synced txg number, the timestamp, the delay since the last MMP update, the VDEV GUID, the VDEV label that received the last MMP update, and the VDEV path.

* Make hostid consistent in user and kernel spaceOlaf Faaland2017-07-131-3/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If no spl_hostid was set, and no /etc/hostid file existed, the user and kernel would have different values for the hostid. The kernel's would be 0. User space's would depend on the libc implementation. On systems with glibc, it would be a generated value, probably the first 4 bytes of an IP address (see man 3 gethostid and comments above hostid_read in SPL for details). This then causes the hostid stored in the labels and in the pool config not to match the hostid userspace obtains from get_system_hostid(). Since the kernel has no way to know the libc's generated hostid value, it serves no purpose for ZFS to use the value. This patch changes user space's get_system_hostid() to conform to the kernel's method, first checking for the spl_hostid via sysfs, and then reading from /etc/hostid directly. It does not look up spl_hostid_path, because if that is set and the file it pointed to exists, spl_hostid will reflect its contents. It eliminates the call to libc's gethostid().

| | | | | | | | | | | | | | | | | | | The sync thread is concurrently modifying dn_phys->dn_nlevels while dbuf_dirty() is trying to assert something about it, without holding the necessary lock. We need to move this assertion further down in the function, after we have acquired the dn_struct_rwlock.

| | | | | | | | | | | | | | Call dpkg-shlibdeps with arguments excluding the Debianized packages lib{uutil1,nvpair1,zfs2,zpool2}linux from the auto-generated dependencies of generated .debs. A shim dh_shlibdeps that calls the real dh_shlibdeps with corresponding arguments is installed into a temporary directory, which is in turn pre-pended to the PATH for the alien call, working around alien's inability to directly alter the dependencies of its output debs.

* Implemented zpool scrub pause/resumeAlek P2017-07-0617-124/+362
| | | | | | | | | | | | | | | | | | Currently, there is no way to pause a scrub. Pausing may be useful when the pool is busy with other I/O to preserve bandwidth. This patch adds the ability to pause and resume scrubbing. This is achieved by maintaining a persistent on-disk scrub state. While the state is 'paused' we do not scrub any more blocks. We do however perform regular scan housekeeping such as freeing async destroyed and deadlist blocks while paused.

The fix is for dmu_sync() to copy db_blkptr to zgd_bp after acquiring the db_mtx. We could still see a stale db_blkptr, but if it is stale then the dirty record will still exist and thus we won't attempt to nopwrite.

* OpenZFS 7600 - zfs rollback should pass target snapshot to kernelAndriy Gapon2017-07-046-14/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Authored by: Andriy Gapon <[email protected]> Reviewed by: Matthew Ahrens <[email protected]> Reviewed by: Pavel Zakharov <[email protected]> Approved by: Robert Mustacchi <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Ported-by: Giuseppe Di Natale <[email protected]> The existing kernel-side code only provides a method to rollback to a latest snapshot, whatever it happens to be at the time when the rollback is actually done. That could be unsafe or confusing in environments where concurrent DSL changes are possible as the resulting state could correspond to a newer or older snapshot than the originally requested one. This change allows to amend that method such that the rollback is performed only when the latest snapshot has a specific name. That is, if a new snapshot is concurrently created or the target snapshot is destroyed, then no rollback is done and EXDEV error is returned. New libzfs_core function lzc_rollback_to() is provided for the new functionality. libzfs is changed to use lzc_rollback_to() to implement zfs rollback command. Perhaps we should return different errors to distinguish the case where the desired snapshot exists but it's not the latest snapshot and the case where the desired snapshot does not exist.
