Fedora 18: reiserfs_open: the reiserfs superblock cannot be found


I'm running Fedora release 18 (Spherical Cow). I just installed it, updated, and then installed Spacewalk.

fdisk -l >

/etc/fstab >

reiserfsck --check /dev/sda2
reiserfs_open: the reiserfs superblock cannot be found on /dev/sda2.
Failed to open the filesystem.

I tried this with the file system mounted and unmounted. I do not believe I have a UUID problem (root is /dev/sda1 and the UUID matches)

echo $? = 8

I tried troubleshooting using tips I found from:

Nothing seems to work. The man page references the exit code "8" stating "operational error"--am I missing something or doing something wrong?

Additional info that may be helpful:

Installing Spacewalk I used the default partitioning for F18. This left me with a root volume too small for the packages being mirrored on the satellite. Root is now full and giving me full errors.

My plan was to resolve this by shrinking /dev/mapper/fedora-home by 100G and adding 100G to root. I read the instructions I found at

Shrink /home, increase /root--it all seemed pretty straight-forward with LVM but I'm stuck on step one. No matter what I do I get the superblock cannot be found error.

Thank you, in-advance!

* one additional comment-- /home mounts without errors. I'll post my entire messages or any other materials needed to troubleshoot.

Your filesystems are formatted as ext4 not reiserfs and I see no need to run fsck on a newly installed system. I suggest using the LVM management GUI to change the logical volumes on the fly.

sda2 is the LVM partition that contains the logical volumes it isn't an actual file system.

This is my first attempt at working with LVM. I'm on a test system with a fresh install so it's a no-risk system.

Your comment and pointer really helped.

Thank you very much!
