* Add *_by-dnode routinesbzzz772017-01-134-75/+260
| | | | | | | | | | | | | | Add *_by_dnode() routines for accessing objects given their dnode_t *, this is more efficient than accessing the object by (objset_t *, uint64_t object). This change converts some but not all of the existing consumers. As performance-sensitive code paths are discovered they should be converted to use these routines.

* 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.

* | OpenZFS 7143 - dbuf_read() creates unnecessary zio_root() for bonus bufBrian Behlendorf2016-12-011-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dbuf_read() creates a zio_root() to track and wait for all the zio's that may happen as part of this call. However, if the blkptr_t for this buffer is NULL or a hole, we will not create any more zio's, so this zio_root() is unnecessary. This is always the case when calling dbuf_read() on a bonus buffer, because it has no blkptr (it's part of the containing dnode). For workloads that read a lot of bonus buffers (e.g. file creation and removal), creating and destroying these unnecessary zio's can decrease performance by around 3%. The fix is to only create/destroy the zio_root() in dbuf_read() if the blkptr is not NULL and not a hole. Changes sponsored by Intel Corp.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In multiple cases zio_buf_alloc() was used instead of kmem_alloc() or vmem_alloc(). This was often done because the allocations could be large and it was easy to use zfs_buf_alloc() for them. But this isn't ideal for allocations which are small or short lived. In these cases it is better to use kmem_alloc() or vmem_alloc(). If possible we want to avoid the case where we have slabs allocated for kmem caches which are rarely used. Note for small allocations vmem_alloc() will be internally converted to kmem_alloc(). Therefore as long as large allocations are infrequent and short lived the penalty for using vmem_alloc() is small.

* Linux 3.14 compat: assign inode->set_acltuxoko2016-11-092-6/+15
| | | | | | | | | | | | | Linux 3.14 introduces inode->set_acl(). Normally, acl modification will come from setxattr, which will handle by the acl xattr_handler, and we already handles that well. However, nfsd will directly calls inode->set_acl or return error if it doesn't exists.

* Add illumos FMD ZFS logic to ZED -- phase 2Don Brady2016-11-071-0/+11
| | | | | | | | | | | | | | | | | | | | | | | The phase 2 work primarily entails the Diagnosis Engine and the Retire Agent modules. It also includes infrastructure to support a crude FMD environment to host these modules. The Diagnosis Engine consumes I/O and checksum ereports and feeds them into a SERD engine which will generate a corres- ponding fault diagnosis when the SERD engine fires. All the diagnosis state data is collected into cases, one case per vdev being tracked. The Retire Agent responds to diagnosed faults by isolating the faulty VDEV. It will notify the ZFS kernel module of the new VDEV state (degraded or faulted). This agent is also responsible for managing hot spares across pools. When it encounters a device fault or a device removal it replaces the device with an appropriate spare if available.
