[linux-lvm] e2fsck error

[linux-lvm] e2fsck error

[hail narcissus]

I am trying to resize my ext2 fs but I get an error from ext2resize:

ext2resize: ext2_open: filesystem has errors! e2fsck first!
ext2resize: can't open /dev/junior/site

At this point I do did a 'umount /dev/junior/site'
Then I do a 'e2fsck -fyv /dev/junior/site &'

It returns this:

Pass 1: Checking inodes, blocks, and sizes
Group 3125's block bitmap at 102400000 conflicts with some other fs block.
Relocate? yes

Group 3125's inode bitmap at 102400001 conflicts with some other fs block.
Relocate? yes

It finds other errors which I believe it fixes but not the above error.  If 
I re-run e2fsck then it comes up with the above error again.

Thanks!!

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.

Running resize2fs was successful.  Got another 140GB added to my LV now.

I'm running e2fsck -fvp now to see if there are any more errors, but it 
doesn't get the errors right off the bat like it use to so it might have 
fixed itself during the resize.

You write:

I can't see that resize2fs would run if there are filesystem errors.  It
is far more paranoid about resizing than ext2resize (it forces you to run
e2fsck, even on a clean filesystem, while ext2resize only needs it if the
filesystem is dirty).

Probably takes a long time, but well worth it...  Maybe the errors were
cleaned up the last time you ran e2fsck?  It would have been useful to
check the filesystem status with "dumpe2fs -h <dev>" before you did the
resize/e2fsck, to see if it was clean or not.
