I have LVM set up on two discs running RAID 1 (sw) and ReiserFS.
I have resized my logical volume /home with
# lvresize -L +20G /dev/system/home-volume
but when I tried resizing the file system :
# resize_reiserfs -f /dev/mapper/system-home--volume
resize_reiserfs 3.6.19 (2003 www.namesys.com)
reiserfs_open: the reiserfs superblock cannot be found on /dev/mapper/system-home--volume.
I have run this both with /home mounted and unmounted, and from runlevel 1,3,5 with the same result.
I have tried google without result. Some suggestions are reiserfsck --rebuild-sb
but these were not mentioned in context with LVM, so I'm wondering if this would work ? I'm afraid of loosing data by trying the rebuild because I'm not sure what it does exactly.
