Hi all! I have a client that have lost two 30 gig disks with a huge number of files he uses in a project. The server (Linux SuSE 9.1) suddenly hickuped, and when it came back there was files on the discs but no NFS. ('df showed about 75% usage of the discs) After restart of NFS a 'df' shows total use 1% and the files are gone By some reason (so far unknown) the disk is suddenly empty. They are created under Linux and uses ReiserFS, so he thought them to be "safe". (No he didn't back them up regardles of warnings from me) I did a 'dd if=/dev/hdc of=image.hdc and if i look at that file i can see all the data. I can find all filenames but the fat seems empty. Is there a safe way to try to restore the lost files? Parttitiontable is OK. ReiserFS in it self didn't complain about anything, and SMART didn't register any failing disks.

Good luck. Reiser is not going to be a well supported os for recovery tools. Surpisingly, googling for "computer forensics reiserfs" turned up more hits than I expected. The first 2 look very promising: WinHex and X-Ways Forensics. http://www.x-ways.net/winhex/index-m.html http://www.x-ways.net/forensics/index-m.html WinHex in particular is a good tool for Windows based problems, I have no exp. with it and Reiser. I've never heard of the X-Ways Forensics tool before. (And forensics is what my company does.) Greg -- Greg Freemyer

You have a backup of the corrupt partition, so we can try to rebuild the fs. Did you reiserfsck --rebuild-tree --scan-whole-partition /dev/hdXX ?? Hope that helps The polarizer Polarizers at it's best http://www.codixx.de/polarizer.html

Just a guess, but since you mentioned NFS, is it possible it mounted something NFS on top of a mount point used by the system, effectively 'hiding' the files from the system? Worth a shot to look I suppose. -- Joe Morris New Tribes Mission Email Address: Joe_Morris@ntm.org Registered Linux user 231871

I had a Suse 9.1 NFS served reiserfs blow up as well. Many files were recovered after using fsck, but the organization was clobbered and certainly no hope of booting it.

I had a couple of failures under reiserfs with 9.1 that were never going to be recoverable whatever filesystem was used. I had a failing IDE port that first caused corruptions that were recoverable, then finally the port died and I had to change the motherboard. Rebuilt 9.1 and it's still OK upgraded to 9.2. I use reiserfs on all 5 boxes (SuSE, Mandrake, gentoo) here without problems since about SuSE 6.2 or 7.2 if my memory serves me correctly.

Yes. However, I'm not one of them.
reiserfs is fine, but like EVERY single filesystem it's a balance of
tradeoffs. My journaling FS of choice is jfs but you really can't go
wrong with ext3 - recent 2.6 kernels also have the ext3 directory
indexing improvements that make ext3 perform considerably better than
before on very large directories, etc... ext2/3 has (by far) the most
robust and comprehensive recovery tools available, period, and ext2/3
withstands media problems better han most.

I guess that depends on "whose benchmarks" and "what workload" and
probably a huge host of other issues (like, which kernel, what mount
options, blah blah blah).
My benchmarks for *my* workloads show reiser getting creamed by jfs and,
for some workloads, ext3 beats reiser as well. It all depends on what
your workloads are.
Admittedly, it's old and (like almost every test) the methodology leaves
a great deal to question, but this test shows ext3 13-14% faster than
resierfs on "create" and 55% faster in 'delete'.
http://seclists.org/lists/linux-kernel/2002/Oct/0554.html
This shouldn't get into a "my filesystem is faster (bigger) than yours"
"discussion", but I wanted to show that your statement that "Reiser is
the best all around for speed" is not universally true and therefore
when stated as a fact can be categorically shown to be /untrue/.
(Disproving a fact is not the same as proving it's opposite, by the way;
I am not saying that reiserfs is not the fastest for /any/ workload, it
very well might be.)

Yes and no... Our experience has been that Reiser is faster on workstations and servers, especially when you go to delete a huge directory tree with 20,000 or more files. But in two cases where we had power failures (the customer would not take our advice and replace old batteries in their UPSs), we could not recover the Reiser filesystem and wound up doing a fresh install of the OS and a restore of data, configs, etc. We now build servers using ext3. Not that I am hoping for another power failure, but it would be interesting to see what happens (the aforementioned client has since installed new batteries...). YMMV (and probably will...)

Yes, I am. Having been burned by ext2 and then by ext3 (non-recoverable disks after power failures), I switched to reiserfs and have not had a single nonrecoverable disk since, expect once on a crypto loop file... I guess this is simply an example of how most of us function: We use what we have until it breaks, then search for alternatives. The first solution which works gets promoted to the current favourite! At least I do not have the time to investigate whether ext3 or anything else really would be better than SuSEs current default reiserfs.

Doesn't this mean the "root", or top, level of the tree on that one partition? Certainly such a directory exists at the top of every separate partition on my system, curiously -except- /. Therefore, I would think this is telling you that the lost+found directory cannot be found on /dev/hdc1. Of course, this should not be surprising, if as you say, the file table for the partition was empty. Maybe it was one of the items whose name pointed to nowhere. The reiserfsck manpage does suggest sending a bug report to the authors if a --rebuild-tree doesn't seem to produce the desired result. See also 'man debugreiserfs' particularly the -p option. Maybe debugreiserfs might even help you fix the problem youself. Another possibility might be to run --rebuild-tree again, with the --no-journal-available option, but I really have no idea what this does, and the manpage does warn us it is for experts. But lucky you, you have an image of the whole device and can restore it to its original (damaged) condition if something gets really mangled :-) The last resort is to take your drive image, and tell the client to pay a lot of money to some data recovery company, hoping they will be able to piece together the data again.

Remove lost+found before running fsck. lost+found it's not there by default on reiserfs, but running fsck --rebuild-tree will automatically create it. However, my experience with --rebuild-tree is painful. A customer erased a 2 GB super-important directory by accident. I had to --rebuild-tree and it created thousands of files named like 123098234-2038 and a few directories that actually were useful. After that, the system was pretty much trashed, it didn't boot, there were missing libraries etc. I have brought it to a sort-of-running state, then recovered the files. Then I have reinstalled it. On other occasions of reiserfs recovery, I had bad blocks spread all over the hard-disk. Also trashed partition table (ie zeroed-out). With all this misfortune, I was still able to recover completely to a running system with the help of an identical hard-disk, dd_rescue, parted and fsck.reiserfs. So, overall I'm happy with reiserfs. I even have my /home on reiser4 :-) and no problems so far. But I have an UPS.
