Troubleshooting Managed Volumes
Correcting Share-Import Errors
CLI Maintenance Guide 8-49
Retaining Nothing from the Share
To remove all traces of the share, you must remove all of the share’s directories from
the volume’s directory tree. This is a serious change in the volume’s metadata, and it
requires that you take the volume offline. Use
nsck ... destage
to take the share offline
(recall “De-Staging a Volume” on page 5-40 ), remove the share from the volume, then
re-enable all of the shares (as shown in “Enabling All Shares in the Volume” on
page 9-53 of the storage-management manual).
For example, the following command sequence shuts down the “wwmed~/acct”
volume, removes the “budget” share, and then enables all of the remaining shares at
once:
bstnA6k(gbl)# end
bstnA6k# nsck wwmed destage volume /acct
This operation will remove entries for all shares in the volume
from the namespace metadata. To reimport a destaged share,
enable the share in namespace-volume-share mode.
Destage all shares from volume /acct in namespace wwmed? [yes/no] yes
bstnA6k# global
bstnA6k(gbl)# namespace wwmed
bstnA6k(gbl-ns[wwmed])# volume /acct
bstnA6k(gbl-ns-vol[wwmed~/acct])# no share budget
bstnA6k(gbl-ns-vol[wwmed~/acct])# enable shares
bstnA6k(gbl-ns-vol[wwmed~/acct])# ...
Reinstating the Share
If you want to bring the share back into the volume, repeat its original configuration.
When you enable the share in the already-enabled volume, the volume imports the
share’s files and directories.
Clients cannot access the volume while it is destaged. NFS clients must unmount and
remount after the volume comes back online. Additionally, all NFS and CIFS services
that host the volume experience a brief (roughly 10-second) outage.
