First, please CC all replies to samuelt@caltech.edu, as I am not on the mailing list.
The other day a computer of mine lost power and the ext2 fs was severely damaged . I decided to reinstall debian using reiserfs to prevent this. I had no problems with installation, (I've done this same install on other computers) but as I started to untar backup tarballs I had made, I started noticing problems with what I believe is the filesystem.
Tar/gzip will complain about crc errors in files: for example in a certain 40 mb file I can decompress fine on other computers. If I try to uncompress the same file immediately, it will fail at a different point, seemingly at random. Sometimes it works fine. Random debian packages I apt-get have the same problem. Sometimes they won't unpack properly, sometimes they will.
I tried reinstall gzip several times, but I don't think the problems are limited to compressed files, just very obvious in critical situations like that.
I can get complex software to run: xfree86 4.1, mozilla, etc, fine, although som e files apparently go missing in some programs.
Just now I got the following error message when deleting a tarball:
vs-4080: reiserfs_free_block: free_block (0301:672040)[dev:blocknr]: bit already cleared
Next, I took the hard drive to my other, stable computer and ran reiserfsck --rebuild-tree on it, under the hopes that this would fix it. It did appear to fix it, but about 10 minutes later the symptoms came back.
Here is 'debugreiserfs /dev/hda1' output:
Super block of format 3.5 found on the 0x3 in block 16 Block count 4233112 Blocksize 4096 Free blocks 3900694 Busy blocks (skipped 16, bitmaps - 130, journal blocks - 8193 1 super blocks, 324078 data blocks Root block 8529 Journal block (first) 18 Journal dev 0 Journal orig size 8192 Filesystem state ERROR Tree height 4 Hash function used to sort names: "tea" Objectid map size 62, max 1004 Version 0
Here is my relevant hardware:
Motherboard: Asus A7V KT133 with 686A southbridge (NOT the 686B). Harddrive: 30 gig ide maxtor/generic.
I installed 2.4.6 to try and fix the problem, it didn't seem to help, although I do not clearly remember the difference between 2.2.17-patched and 2.4.6 in terms of the symptoms.
I tried reinstalling once, but that did not help.
I'm at a loss as to how to proceed. Any ideas?
Thank you for your time,
