Rename Logical volume and mount point on SUSE Linux.
while doing day today administration task on SUSE linux one day i got task to rename existing LV name and mount point.when i got this task first thought in my mind was ,is it possible while File system is in mounted state ??.so answer to this is NO.
Here is the scenario
Filesystem Type Size Used Avail Use% Mounted on
/dev/mapper/vg01-lvopt_IBM ext3 9.8G 2.8G 6.5G 30% /opt/IBM
Rename LV name from lvopt_IBM to lvopt_IBMNew and chnage mount point to /opt/IBMNew
solution:
1.First take fstab file backup using command
cp /etc/fstab /etc/org_fstab
2.mkdir -p /opt/IBMNew //make sure that same name directory not exist in mentioned path.
3.umount /opt/IBM
4.lvrename vg01 lvopt_IBM lvopt_IBMNew
syntax: lvrename [vg name] old_lv_name new_lv_name
5.Change /etc/fstab entry with New LV and mount point name
old
/dev/vg01/lvopt_IBM /opt/IBM ext3 defaults 1 2
New
/dev/vg01/lvopt_IBMNew /opt/IBMNew ext3 defaults 1 2

6. mount /opt/IBMNew
Check mounted file system using command
df -hT /opt/IBMNew
