mrconfig sp offline all

The 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 file system 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 (file system check) command can be run on disks or storage pools if there are lost or corrupt containers, directories, tables, files, filelets, or blocks.

After running fsck the storage pools are brought back online with the mrconfig sp online command, and then typically the gfsck (global file system check) command would be run on the affected cluster, volumes, or snapshots.

See mrconfig for instructions on running mrconfig commands.
