If all mirrors of a volume become STALE
, you can place the volume in maintenance mode. Then you can view the plexes while the volume is DETACHED
and determine which plex to use for reviving the others. To place a volume in maintenance mode, use the following command:
# vxvol [-g
diskgroup] maint
volume
To assist in choosing the revival source plex, use vxprint
to list the stopped volume and its plexes.
To take a plex (in this example, vol01-02
in the disk group, mydg
) offline, use the following command:
The vxmend
on
command can change the state of an OFFLINE
plex of a DISABLED
volume to STALE
. For example, to put a plex named vol01-02
in the STALE state, use the following command:
Running the vxvol
start
command on the volume then revives the plex as described in the next section.
