Hi list,
Attached to a Dell PE8450 (8 CPUs, 4GB RAM) we have a PowerVault 210
Storage with 12 70GB SCSI disks in a RAID5 container w/ spare disk
managed by a
scsi2 : Found a MegaRAID controller at 0xf8853000, IRQ: 24
scsi2 : Enabling 64 bit support
megaraid: [1.73:3.27] detected 1 logical drives
The machine is primarily running as NFS server under kernel 2.4.21 and
now under 2.4.23, reiserfsprogs 3.6.11. Twice already I had to run
`reiserfsck --rebuild-tree` this year due to weird corruption issues.
Since a couple of weeks (when the server was running under 2.4.21),
we've seen strange console output and users were claiming files had been
lost or they would get "permission denied" errors.
Example console output:
Dec 1 05:28:37 sim0 kernel: vs-5150: search_by_key: invalid format

As the output suggested, I ran reiserfsck. I don't have the log of that
check, but it ended suggesting to run `reiserfsck --rebuild-tree`. As I
said, I've done --rebuild-tree twice already over one year and there
were no problems so far. This time, the fsck bombed out with a
Segmentation Fault after running for about 10 hours. I started it again,
sorry, I have no log, it stopped after 10 hours of running again with a
Segementation Fault.
When I try to mount it, the dmesg output is:
reiserfs: found format "3.6" with standard journal
reiserfs: checking transaction log (device sd(8,38)) ...
for (sd(8,38))
is_tree_node: node level 0 does not match to the expected one 65534
sd(8,38):vs-5150: search_by_key: invalid format found in block 0. Fsck?

find stat data of [1 2 0x0 SD]

sd(8,38):vs-5150: search_by_key: invalid format found in block 0. Fsck?
sd(8,38):vs-2140: finish_unfinished: search_by_key returned -2
When I run a simple `reiserfsck` it says:
Replaying journal..
0 transactions replayed
Checking internal tree..
Bad root block 0. (--rebuild-tree did not complete)
Aborted
Should I start restoring from tape?

Would you run
debugreiserfs -p /dev/problem_device | bzip2 -c > metadata.bz2
and make it available for downloading. I will debug the problem
locally then.

Let's try to find the problem first.

It is running now. I'll make the file metadata.bz2 available for
downloading asap. ETA is 10h, right, if the `reiserfsck --rebuild-tree`
took 10h before it segfaulted?

That gives hope... ;)

No. More like a few minutes for disk accesses and some time for
compressing the result. The command is of the "read all metadata and dump
it without any additional checks whatsoever" variety.

Hmm, it's running for 15' now and it does not look like it's going to
finish soon:
debugreiserfs 3.6.11 (2003 www.namesys.com)
Loading on-disk bitmap .. 162980857 bits set - done
super block..ok
bitmaps..(5396).. ok
journal (from 18 to 8210)..ok
Super block, bitmaps, journal - 13590 blocks - done, 162967267 blocks left
0% left 161169318,
1250 /sec
The file metadata.bz2 is still growing. The 1250 /sec increased slowly
during fsck and went up to 6000 /sec towards the end. At the current
pace, it would take 36h...

Sorry, I totally underestimated your disk_size/transfer_rate ratio. Your
disks are probably 1000x larger than mine (4GB), but not 1000x faster.
