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-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.
After running
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.
See
mrconfig
for instructions on running mrconfig
commands.
