Changing SNFS disk labels

un-mount the active file system from all clients
run cvadmin -e ‘stop <file system name>’
run cvfsck -j <file system name> (flushing the journal, should not be required but …)
run cvfsck <file system name> expecting no errors; stop here on errors
create a backup of the metadata using snmetadump
being paraniod helps, check the metadump with snmetadump
run cvlabel -c > /my_labels
run cvlabel -c > /tmp/my_new_labels
copy /usr/cvfs/config/<file system name>.(x)cfg to /usr/cvfs/config/<file system name>.(x)cfg.org
edit /tmp/my_new_labels to change device labels names as desired
edit /usr/cvfs/config/<file system name>.(x)cfg to reflect “new_labels”
run cvlabel /tmp/my_new_labels to relabel devices
run cvadmin -e ‘start <file system name>’
run cvadmin -e ‘activate <file system name>’
mount file system and verify
