mrconfig sp offline command takes a loaded storage pool offline. When a storage pool is offline it remains loaded into memory but it is not available to MapR-FS for reads and writes.
The main use of the
mrconfig sp offline command is to take a storage pool offline so the
fsck (filesystem check) command can be run on one or more disks or storage pools if there are lost or corrupt containers, directories, tables, files, filelets, or blocks.
fsck the storage pool is brought back online with the
mrconfig sp online command, and then typically the
gfsck (global filesystem check) command would be run on the affected cluster, volumes, or snapshots.
