Issue with CFS mounts
Attempts to mount the CFS mounts on a global zone, after they are unmounted using the hares or umount command, fail with the following error if the CFS mounts on the global zone are mounted on a non-global zone as an lofs file system:
VCS WARNING V-16-20011-5508 (sys1) CFSMount:ocrvote_mnt:online:Mount Error : UX:vxfs mount: ERROR: V-3-21264: /dev/vx/dsk/ocrvotedg/ocrvotevol is already mounted, /ocrvote is busy,allowable number of mount points exceeded
Workaround:
Perform the following steps to resolve the issue:
Log into the global zone as the root user.
View the CFS and lofs mounts that are unmounted on the global zone:
# cat /etc/mnttab |grep mount_point
For example:
# cat /etc/mnttab |grep ocrvote/ocrvote \ /zonevol/sys1_zone1/root/ocrvote lofs \ dev=53859d8 12971587943
Unmount the CFS and lofs mounts:
# umount /zonevol/sys1_zone1/root/mount_point
Check if there are any active CFS and lofs mounts:
# cat /etc/mnttab |grep mount_point
Mount the CFS and lofs mounts in one of the following ways on the global zone.
Using hares command:
# hares -online res_name -sys sys_name
Manually:
# mount -F vxfs -o cluster /dev/vx/dsk/\ dg_name/vol_name /mount_point
Verify if the CFS mounts are mounted successfully:
# cat /etc/mnttab |grep mount_point
For example:
# cat /etc/mnttab |grep ocrvote/dev/vx/dsk/ocrvotedg/ocrvotevol \ /ocrvote vxfsrw,suid,delaylog,largefiles,qio,cluster,\ ioerror=mdisable,crw,dev=53859d8 1297159501
