mrconfig sp offline
The 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
Data Fabric file system for reads and writes.
The main use of the mrconfig sp offline
command is to take a storage
pool offline so the
fsck
(file system 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.
After running
fsck
the storage pool is 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.
