| | | | | | | | | | | | | | | | | | | | Instead of asserting all zio's be properly aligned, only assert on the logical ones. Cap uberblocks at 8k, otherwise with ashift=17, there would be only one uberblock. This fixes a problem that zdb would trip assert on pools with ashift >= 0xe (8k). While there, also change the code so it only attempt to condense space map unless the uncondensed size consumes greater than zfs_metaslab_condense_block_threshold blocks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Improve extreme rewind import. When doing an "extreme rewind" import ("zpool import -XF"), we attempt to verify all data in the pool, essentially scrubbing the entire pool. The problem is that spa_load_verify_cb() issues an unbounded number of concurrent scrub i/os. This can lead to all of memory being used for these zio's, wedging the system. Like normal scrub, we need to put a cap on the number of outstanding i/os, and have the traverse thread block when we reach this cap. For this purpose the cap can be very large (10,000) to optimize the elevator algorithm. Three kernel tunables have been added: vfs.zfs.spa_load_verify_maxinflight vfs.zfs.spa_load_verify_metadata vfs.zfs.spa_load_verify_data The latter two tunables controls whether metadata and/or user data when doing extreme rewind. Make 'zpool import -T' imply scrub. Make zpool import -T <txg> accept hexadecimal values for the txg when prefixed with 0x. Skip txg's for which there is no uberblock when doing extreme rewind. Skip reading all user data twice by skipping prefetches when doing extreme rewinds as we do not access via the ARC. Illumos issues: 4970 need controls on i/o issued by zpool import -XF 4971 zpool import -T should accept hex values 4972 zpool import -T implies extreme rewind, and thus a scrub 4973 spa_load_retry retries the same txg 4974 spa_load_verify() reads all data twice MFC after: 2 weeks

| | | | | | | | | | | | | | | | | | Use reserved space for ZFS administrative commands. We reserve 1/2^spa_slop_shift = 1/32 or 3.125% of pool space (or 32MB at least) for system use. Most ZPL operations, e.g. write(2), creat(2), will fail with ENOSPC if we fall below this. Certain operations, e.g. file removal and most administrative actions, still permitted until half of the slop space is used. This would allow users to use these operations to free up space in the pool when pool is close to full but half of slop space is still free. A very restricted set of operations that frees up space or change quota are always permitted, regardless of the amount of free space. MFC after: 2 weeks

| | | | | | | | | | | | | | | | | | | | | Add a new zfs property, "redundant_metadata" which can have values "all" or "most". The default will be "all", which is the current behavior. When set to all, ZFS stores an extra copy of all metadata. If a single on-disk block is corrupt, at worst a single block of user data (which is recordsize bytes long) can be lost. Setting to "most" will cause us to only store 1 copy of level-1 indirect blocks of user data files. This can improve performance of random writes, because less metadata has to be written. In practice, at worst about 100 blocks (of recordsize bytes each) of user data can be lost if a single on-disk block is corrupt. The exact behavior of which metadata blocks are stored redundantly may change in future releases. Illumos issue: 3835 zfs need not store 2 copies of all metadata MFC after: 2 weeks
