Resized lvm, but Reiserfs won't be resized.
I have resized my logical volume /home with
# lvresize -L +20G /dev/system/home-volume
# 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 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.
Here is my df -h output

As you can see these are the /dev/mapper names. Not sure if that's what you meant, though as the path was already specified in the first post ?
I have resized the logical volume /dev/mapper/system-home--volume to 140G. But the file system remains as shown. I don't think the hyphens are the problem since the lvm operations went fine.
edit: /dev/system contains links to /dev/mapper btw.
Ah, here is the reason for the double hyphens: http://lists.debian.org/debian-boot/.../msg00823.html
edit: I should also mention that i have tried
resize_reiserfs -f /dev/system/home-volume
I made a huge blunder. I have previously used ReiserFS, but when I reinstalled maybe 6 months ago I chose ext3 and had forgotten about it. Embarrassing...
But now the problem is solved at least.
