So this is what i want to achieve,
- Unmount home partition at /home
- Remove home logical volume /dev/cl/home
- create new home logical volume from the same volume
group cl and name home- make xfs filesystem
- mount the new logical volume at /home.
for that i wrote this bash script
umount -v /home/ if [ $? -ne 0 ] then echo "Couldn't not unmount /home" exit 1 fi # delete lvremove /dev/cl/home if [ $? -ne 0 ] then echo "Couldn't delete LVM /dev/cl/home." exit 1 fi # create home lvcreate -L2G -n home cl if [ $? -ne 0 ] then echo "Couldn't create a new LVM /dev/cl/home." exit 1 fi mkfs.xfs /dev/cl/home if [ $? -ne 0 ] then echo "Couldn't create a file system for /dev/cl/home." exit 1 fi # restore home mount /dev/cl/home /home/
the script fails at the line mkfs.xfs /dev/cl/home with msg
mkfs.xfs: /dev/cl/home contains a mounted filesystem
, it seemslvcreate -L2G -n home cl
doesn’t really create a new logical volume it just retrieves the previously removed logical volume with the same filesystem and mount it at the same mounting point /home, what could possible cause this?
