Subject: [linux-lvm] growing snapshots beyond original lv size
Date: Tue, 21 Aug 2007 17:08:51 +0200 (CEST) [thread overview]
Message-ID: <alpine.LRH.0.999.0708211658250.24950@linuxbox.linuxbox.cz> (raw)
Hello,
I'd like to ask a question regarding snapshots.
My scenario:
I have LV with some data, ie 2GB size.
Then I create it's snapshot, also 2GB size.
Is it possible to enlarge snapshot to ie 4GB to get 4GB of usable
capacity?
If I try to resize it using lvextend, lvdisplay then says that COW-table
size is 4GB, but LV size is still 2GB (and the device is really only 2GB
large).
So my question is:
is it possible to enlarge snapshots this way? if yes, what am I doing
wrong??
thanks a lot for any advice
with best regards
Nikola Ciprich
