How to remove a LV(logical volume) in an AIX server ?
Today in this article we will look how to remove a logical volume from a VG on IBM AIX server.
Lets have a look at this one by one to understand how to check the LV and remove it from VG.
1. Check out the available disks and logical partitions in VG.
ngeaix005 --> lsvg -p backupvg backupvg: PV_NAME PV STATE TOTAL PPs FREE PPs FREE DISTRIBUTION hdisk16 active 15998 157 154..00..00..00..03 ngeaix005 --> lsvg -l backupvg backupvg: LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT ngeltlv jfs2 2240 2240 1 open/syncd /backup/ngelnft loglv01 jfs2log 1 1 1 open/syncd N/A ngeltlv jfs2 11440 13300 1 open/syncd /backup/ngelp04 ngeaix005 -->
2. Umount the filesystem.
ngeaix005 --> umount /backup/ngelp04
3. Now remove this filesystem which will automatically remove LV.
ngeaix005 --> rmfs /backup/ngelp04 rmlv: Logical volume ngelplv is removed.
4. Check out the LVs now.
We can see the LV is now deleted.
ngeaix005 --> lsvg -p backupvg backupvg: PV_NAME PV STATE TOTAL PPs FREE PPs FREE DISTRIBUTION hdisk16 active 15998 13757 959..3200..3199..3199..3200 ngeaix005 --> lsvg -l backupvg backupvg: LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT ngeltlv jfs2 2240 2240 1 open/syncd /backup/ngelnft loglv01 jfs2log 1 1 1 open/syncd N/A
5. Now remove the entry from /etc/filesystems file.
ngeaix005 --> vi /etc/filesystems
That’s it ! Now the LV/FS is removed and is removed from auto-mount.
