Indtil for få timer siden var jeg en glad ReiserFS bruger.

Maskinen kører squid og samba ovenpå en 90Gb Software RAID5 partion. Kernen
er 2.4.0-test10 med reiserfs version 3.6.19.

I formiddags kunne jeg så mærke der var noget galt med partionen - en del
processer hang med status D i en 'ps xa' og jeg rebootede til singleuser.

Nogen der erfaringer, gode såvel som dårlige, med at køre en reiserfsck --
rebuild-sb og især --rebuild-tree på jeres reisefs partioner?

Efter at RAID'et havde resync'et forsøger jeg at remounte min reiserfs
partion, og får meddelserne der ses nederst i min syslog. Jeg har nu kørt
en reiserfsck --check på partionen, der giver flg:

[x@x /x]# reiserfsck --check /dev/xp0
<-------------reiserfsck, 2000------------->
reiserfsprogs 3.x.0b

Hej, jeg har med held brugt --rebuild-tree på en lettere defekt reiserfs.
Al data var der stadig bagefter :)

Did that, done that, did not work:

[x@x x]# reiserfsck --rebuild-tree /dev/x0

<-------------reiserfsck, 2000------------->
reiserfsprogs 3.x.0b

This is an experimental version of reiserfsck, MAKE A BACKUP FIRST!
Don't run this program unless something is broken.
Some types of random FS damage can be recovered
from by this program, which basically throws away the internal nodes
of the tree and then reconstructs them. This program is for use only
by the desperate, and is of only beta quality. Email
reiserfs@devlinux.com with bug reports.
Will rebuild the filesystem tree
Will put log info to stderr
