Hello,

On a test environment, I have created a volume group vg1 and inside that added 1 pv. Created a logical volume lv1 and the size of the lv
became 18GB. Formatted the logical volume and mounted the logical volume. Created few files in it. Now added another PV to VG1 inorder
to increase the size. Then used,

lvextend -L +30G lv1 , the command completed successfully.

But now the mounted lv1 is still showing the original size 18GB. I remounted the same but no help.

Anything to execute to take new change effect?

Thanx,
admin

You didn't run resize2fs...


cheers

Ok I ran resize2fs after unounting the filesystem. And it asked me to run

e2fsadm -f /dev/vg1/lv1

Is it necessary? Why? Will it harm the inside data?

The new command is 'e2fsck'.. and no, it shouldn't harm the filesystem, it's just asking you to check it

cheers
