[linux-lvm] e2fsck error

You should probably run "e2fsck -fpv /dev/junior/site", because there
are a few anwers which should be "n" and not "y".  The "-p" option
will pick the right one (-y always answers "y").  It may not make a
difference in this case.  Also, don't run it in the background, in
case it wants to ask some questions.

Strangely, the bitmaps are in the same location as a superblock and group
descriptor backup (group 3125 = 5^5 is a "sparse" group).

Strange.  e2fsck _should_ be able to fix this, but maybe it has never
been tested before.  How did you get into this situation in the first place?
Your previous posting indicated that you weren't running e2fsck on your
filesystem with errors?  What version of ext2resize are you using?  Did
you ever "force" a resize?  In any case, probably a good time to make a
backup.

Cheers, Andreas
