Rebuilding a Volume
You can narrow the focus of an
nsck rebuild
to a single volume:
nsck namespace rebuild volume volname
where:
name (1-30 characters) is the name of the namespace to rebuild. Use the
show namespace
command to see a list of configured namespaces.
volume volname (optional, 1-256 characters) limits the rebuild to the chosen
volume (for example, ‘/home’).
The CLI prompts for confirmation before re-importing the volume’s shares: enter yes
to continue. Enter no to cancel the rebuild.
For example, the following command sequence exits to priv-exec mode and rebuilds
the ‘/etc’ volume in the ‘archives’ namespace:
bstnA6k(gbl)# end
bstnA6k# nsck archives rebuild volume /etc
Reimport all shares from volume /etc in namespace archives? [yes/no] yes
bstnA6k# show nsck

As mentioned above, this stops all managed-volume modifications (client writes and file
renames on import) after the rebuild. Essentially, the nsck utility issues a
no modify
for
the volume.
To guarantee that modifications are enabled after the rebuild, run the
modify
command
and raise the
reimport-modify
flag before you rebuild the volume. The reimport-modify
flag stops the nsck utility from running
no modify
on the volume.
If do not do this but the rebuild/import succeeds without any collisions, you can use the
modify
command after the rebuild.
