It would be nice to preserve as much of the logical order as possible. In addition, the allocations are equally scattered across all top-level VDEVs but not all top-level VDEVs are created equally. The pipeline should be able t o detect devices that are more capable of handling allocations and should allocate more blocks to those devices. This allows for dynamic allocation distribution when devices are imbalanced as fuller devices will tend to be slower than empty devices. The change includes a new pool-wide allocation queue which would throttle and order allocations in the ZIO pipeline. The queue would be ordered by issued time and offset and would provide an initial amount of allocation of work to each top-level vdev. The allocation logic utilizes a reservation system to reserve allocations that will be performed by the allocator. Once an allocatio n is successfully completed it's scheduled on a given top-level vdev. Each top- level vdev maintains a maximum number of allocations that it can handle (mg_alloc_queue_depth). The pool-wide reserved allocations (top-levels * mg_alloc_queue_depth) are distributed across the top-level vdevs metaslab groups and round robin across all eligible metaslab groups to distribute the work. As top-levels complete their work, they receive additional work from the pool-wide allocation queue until the allocation queue is emptied.

It's possible that a stale configuration that comes with extra vdevs, where metaslab_init() would fail because of lower layer returns error.

| | | | | | | | | | | | | | | | | | | | | ZFS large block support. The default recordsize remains at 128KB. A new tunable/sysctl variable, vfs.zfs.max_recordsize is added to allow adjusting the permitted maximum record size, or zfs_max_recordsize, with a default of 1MB. ZFS will not allow setting recordsize greater than zfs_max_recordsize as a safety belt, because larger recordsize means greater read and write latency and more memory usage. Please note that booting from datasets that have recordsize greater than 128KB is not supported (but it's Okay to enable the feature on the pool). Limited safety belt is provided for mounted root filesystem but use caution when using a larger value. Illumos issue: 5027 zfs large block support

Use this information to automatically increase ZFS's minimum allocation size for new top-level vdevs to a value that more closely matches the optimum device allocation size. Use GEOM's stripesize attribute, if set, as the physical sector size of the GEOM. Calculate the minimum blocksize of each metaslab class. Use the calculated value instead of SPA_MINBLOCKSIZE (512b) when determining the likelyhood of compression yeilding a reduction in physical space usage. Report devices with sub-optimal block size configuration in "zpool status". Also properly fail attempts to attach devices with a logical block size greater than 8kB, since this will cause corruption to ZFS's label area. Sponsored by: Spectra Logic Corporaion MFC after: 2 weeks Background ========== Many modern devices use physical allocation units that are much larger than the minimum logical allocation size accessible by external commands. Two prevalent examples of this are 512e disk drives (512b logical sector, 4K physical sector) and flash devices (512b logical sector, 4K or larger allocation block size, and 128k or larger erase block size). Operations that modify less than the physical sector size result in a costly read-modify-write or garbage collection sequence on these devices. Simply exporting the true physical sector of the device to ZFS would yield optimal performance, but has two serious drawbacks: 1) Existing pools created with devices that have different logical and physical block sizes, but were configured to use the logical block size (e.g. because the OS version used for pool construction reported the logical block size instead of the physical block size) will suddenly find that the vdev allocation size has increased. This can be easily tolerated for active members of the array, but ZFS would prevent replacement of a vdev with another identical device because it now appears that the smaller allocation size required by the pool is not supported by the new device. 2) The device's physical block size may be too large to be supported by ZFS. The optimal allocation size for the vdev may be quite large. For example, a RAID controller may export a vdev that requires read-modify-write cycles unless accessed using 64k aligned/sized requests. ZFS currently has an 8k minimum block size limit. Reporting both the logical and physical allocation sizes for vdevs solves these problems. A device may be used so long as the logical block size is compatible with the configuration. By comparing the logical and physical block sizes, new configurations can be optimized and administrators can be notified of any existing pools that are sub-optimal. sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/spa.h: Add the SPA_ASHIFT constant. ZFS currently has a hard upper limit of 13 (8k) for ashift and this constant is used to both document and enforce this limit. sys/cddl/contrib/opensolaris/uts/common/sys/fs/zfs.h: Add the VDEV_AUX_ASHIFT_TOO_BIG error code. Add fields for exporting the configured, logical, and physical ashift to the vdev_stat_t structure. Add VDEV_STAT_VALID() macro which can be used to verify the presence of required vdev_stat_t fields in nvlist data. sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev.c: Provide a SYSCTL_PROC handler for "max_auto_ashift". Since the limit is only referenced long after boot when a create operation occurs, there's no compelling need for it to be a boot time configurable tunable. This also allows the validation code for the max_auto_ashift value to be contained within the sysctl handler. Populate the new fields in the vdev_stat_t structure. Fail vdev opens if the vdev reports an ashift larger than SPA_MAXASHIFT. Propogate vdev_logical_ashift and vdev_physical_ashift between child and parent vdevs as is done for vdev_ashift. In vdev_open(), restore code that fails opens for devices where vdev_ashift grows. This can only happen now if the device's logical ashift grows, which means it really isn't safe to use the device. sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/vdev_impl.h: sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev.c: sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_file.c: sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_geom.c: sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_mirror.c: sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_missing.c: sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_raidz.c: sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_root.c: Update the vdev_open() API so that both logical (what was just ashift before) and physical ashift are reported. sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/vdev_impl.h: Add two new fields, vdev_physical_ashift and vdev_logical_ashift, to vdev_t. sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev.c: sys/cddl/contrib/opensolaris/uts/common/fs/zfs/spa_config.c: sys/cddl/contrib/opensolaris/uts/common/fs/zfs/spa.c: Add vdev_ashift_optimize().

The l2arc code performs has it's own code for deciding if compression is worth while, so this effectively disables zio_compress_data() from second guessing the original decision. sys/cddl/contrib/opensolaris/uts/common/fs/zfs/zio.c: In zio_write_bp_init(), use the minimum blocksize of the normal metaslab class when compressing data.

Huge performance improvements mostly for random read of mostly static content. - slog Allow to use additional disks for ZFS Intent Log to speed up operations like fsync(2). - vfs.zfs.super_owner Allows regular users to perform privileged operations on files stored on ZFS file systems owned by him. Very careful with this one. - chflags(2) Not all the flags are supported. This still needs work. - ZFSBoot Support to boot off of ZFS pool. Not finished, AFAIK. Submitted by: dfr - Snapshot properties - New failure modes Before if write requested failed, system paniced. Now one can select from one of three failure modes: - panic - panic on write error - wait - wait for disk to reappear - continue - serve read requests if possible, block write requests - Refquota, refreservation properties Just quota and reservation properties, but don't count space consumed by children file systems, clones and snapshots. - Sparse volumes ZVOLs that don't reserve space in the pool. - External attributes Compatible with extattr(2). - NFSv4-ACLs Not sure about the status, might not be complete yet. Submitted by: trasz - Creation-time properties - Regression tests for zpool(8) command. Obtained from: OpenSolaris
