mrconfig sp offline all command takes all of a node's loaded storage pools 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 all command is to take all storage pools on a node offline so the
fsck (filesystem check) command can be run on disks or storage pools if there are lost or corrupt containers, directories, tables, files, filelets, or blocks.
fsck the storage pools are 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.
