zpool import progress kstat
When an import requires a long MMP activity check, or when the user
requests pool recovery, the import make take a long time. The user may
not know why, or be able to tell whether the import is progressing or is
hung.
Add a kstat which lists all imports currently being processed by the
kernel (currently only one at a time is possible, but the kstat allows
for more than one). The kstat is /proc/spl/kstat/zfs/import_progress.
The kstat contents are as follows:
pool_guid load_state multihost_secs max_txg pool_name
16667015954387398 3 15 0 tank3
load_state: the value of spa_load_state
multihost_secs: seconds until the end of the multihost activity
check; if over, or none required, this is 0
max_txg: current spa_load_max_txg, if rewind is occurring
This could be used by outside tools, such as a pacemaker resource agent,
to report import progress, or as a part of manual troubleshooting. The
zpool import subcommand could also be modified to report this
information.
