I'm planning to re-size space on my LVM and I know that I can to that online/on the fly (so I dont need to stop applications and umount fs).
The following should do this:
# lvresize -L +100G /dev/Vol01/opt
# resize2fs /dev/Vol01/opt
However, data there are extremely important for me.
I would like ask you did any of you have any problems with online
resizing LVM ?
