Hi All,
I have one snapshot problem on ext3
filesystem.
I use RedHat 8.0, and I use lvm tools to create one
snapshot.
Then I use lvextend to extend the snapshot volume,
I can no longer mount it
My steps are as below:
1. First I create a volume group called test, and
create a volume called vol
2. I use lvcreate to create snapshot
lvcreate -s -l 50 -n snap1
/dev/test/vol
3. mount snapshot
mount /dev/test/snap1
/mnt/snap1
4. umount snapshot
umount
/dev/test/snap1
5. use lvextend to extend the snapshot
size
lvextend -l +10
/dev/test/snap1
6. mount snapshot again
mount /dev/test/snap1
/mnt/snap1
But error occur...the error message
is:
mount: block device /dev/test/snap1 is
write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on
/dev/test/snap1,
or too many
mounted file systems
Regards,
Kent
