Sender: linux-lvm-admin@sistina.com Errors-To: linux-lvm-admin@sistina.com Reply-To: linux-lvm@sistina.com List-Help: List-Post: List-Subscribe: , List-Unsubscribe: , List-Archive: List-Id: To: linux-lvm@sistina.com Hi! I have had problems with resizing (shrinking) a reiser fs on a lv. The fs resizing wasn't completed, but the lv was resized than. So I wonder if I can "undo" the resizing of the lv? In fact, the lv would have to take the same space as before, so I could do fsck and rebuild my fs. Thank You, CU, Lars. www.rechnerpool.com The messgae from the reiserfs-list follows: ___ LOG> Hi! LOG> This is part two of my report of a failed resize: LOG> Yesterday I tried to resize a reiser fs. It is build on a LVM partition. LOG> As I know that there is some calculation to make the resize of LVM an LOG> Reiserfs fit, I used the script resize_rfs from the German magazine LOG> Linuxmagazin (6/2000). This script is doing some checks and calculations LOG> on parameters. So I tried to shrink my fs from 320 to 290 GB. can you send that script to me ? LOG> But the process was interrupted, so the fs wasn't resized completely, LOG> while the script did go on to the next step and resized the logical LOG> volume to 290 GB. LOG> So there are two errors in the fs: there is a started, but not completed LOG> resize of the fs AND the fs is on a lvm-volume that is smaller than the LOG> filesystem. LOG> What should I do? I would usually try to set the size of the lv back to LOG> 320 GB. Yes. But I do not know how to force LVM system to allocate same disk space in same order for your logical volume again :( LOG> Should I do a fsck than? Yes. run reiserfsck --check /dev/... , then follow the instructions. LOG> Is there a way to keep the data (else I LOG> will have to replay from the backup, so I should start soon)? I think you should try to restore LV and then run reiserfsck on it. LOG> Thank You, CU, Lars. -- Thanks, Alex. -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net
