Olaf Faaland ca95f70dff 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.
