Why ? The use of LVM should avoid the need to resize partitions (PVs). > root@b2:~# e2fsck -f /dev/mapper/bubba-storage > e2fsck 1.42.12 (29-Aug-2014) > Pass 1: Checking inodes, blocks, and sizes > Pass 2: Checking directory structure > Pass 3: Checking directory connectivity > Pass 4: Checking reference counts > Pass 5: Checking group summary information > Bubba_home: 114439/59703296 files (0.4% non-contiguous), \ > 4001648/119386112 blocks > > At this step I think I forgot to run again: > root@b2:~# resize2fs -p /dev/mapper/bubba-storage 20G > > root@b2:~# lvresize --size 2.1G /dev/mapper/bubba-storage > Rounding size to boundary between physical extents: 2.10 GiB > WARNING: Reducing active logical volume to 2.10 GiB > THIS MAY DESTROY YOUR DATA (filesystem etc.) > Do you really want to reduce storage?

The bad news is that you probably screwed the filesystem. LVM provides flexibility over plain partitions, but at the cost of complexity and is less tolerant to such a mistake. With a plain partition, all you would have to do to fix the mistake is to extend the reduced partition (not the filesystem) to its original size. However, with LVM, if you extend a reduced LV to its original size, nothing guarantees that it will use the same physical blocks as before. You can try, but it may not restore the filesystem's integrity. Run fsck to check the damage. Edit : check in /etc/lvm/backup for a metadata backup of the previous situation of the VG "bubba". Using it to restore the LV is beyond my knowledge, but if your data is important and you don't have a backup (sounds like an oxymoron), my advice is don't touch anything until you find how to restore the LV. Otherwise, just extend the LV and recreate the filesystem on it. > Now what can I do to correct the partitions? There is no partition to correct. The problem is in the LV bubba/storage and its filesystem. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
