MFC r332426: allow ZFS pool to have temporary name for duration of current import

2018-05-03T06:34:07Z

The change adds -t option to zpool create and -t option to zpool import in its form with an old name and a new name. This allows to import (or create) a pool under a name that's different from its real, permanent name without affecting that name. This is useful when working with VM images or images of other physical systems if they happen to have a ZFS pool with the same name as the host system. Sponsored by: Panzura (porting)

9235 rename zpool_rewind_policy_t to zpool_load_policy_t illumos/illumos-gate@5dafeea3ebd2dd77affc802bcb90f63faf01589f We want to be able to pass various settings during import/open of a pool, which are not only related to rewind. Instead of adding a new policy and duplicate a bunch of code, we should just rename rewind_policy to a more generic term like load_policy. For instance, we'd like to set spa->spa_import_flags from the nvlist, rather from a flags parameter passed to spa_import as in some cases we want those flags not only for the import case, but also for the open case. One such flag could be ZFS_IMPORT_MISSING_LOG (as used in zdb) which would allow zfs to open a pool when logs are missing.

MFC r331701: MFV r331695, 331700: 9166 zfs storage pool checkpoint

2018-04-16T04:10:56Z

illumos/illumos-gate@8671400134a11c848244896ca51a7db4d0f69da4 The idea of Storage Pool Checkpoint (aka zpool checkpoint) deals with exactly that. It can be thought of as a “pool-wide snapshot” (or a variation of extreme rewind that doesn’t corrupt your data). It remembers the entire state of the pool at the point that it was taken and the user can revert back to it later or discard it. Its generic use case is an administrator that is about to perform a set of destructive actions to ZFS as part of a critical procedure. She takes a checkpoint of the pool before performing the actions, then rewinds back to it if one of them fails or puts the pool into an unexpected state. Otherwise, she discards it. With the assumption that no one else is making modifications to ZFS, she basically wraps all these actions into a “high-level transaction”.
