Hello,
I think I've just lost a reiserfs partition and reiserfsck did not work. Here is my bugreport, as the man page of reiserfsck says. The system is Intel 486, 66 MHz, 16 MB RAM. /dev/hda1 boot partition with ext2 /dev/hda2 root partition with reiserfs I've installed the system with Suse 8.0, the system booted (many times), then hang and I switched off. The next boot, the kernel paniced with the message read_super_block: can't find a reiserfs filesystem on (dev 03:02, block 64, size 1024) Thus I've downloaded reiserfsprogs-3.6.3.tar.gz and did tar -xzf reiserfsprogs-3.6.3.tar.gz cd reiserfsprogs-3.6.3 ./configure make cd fsck gcc --static -g -O2 -Wall -o reiserfsck main.o pass0.o pass1.o pass2.o semantic_check.o semantic_rebuild.o pass4.o lost+found.o ubitmap.o uobjectid.o ustree.o ufile.o check.o check_tree.o info.o super.o ../lib/libmisc.a ../reiserfscore/libcore.a to get a statically liked version of reiserfsck (unser Suse Linux 8.0, gcc 2.95.3, Suse's default 2.4.18-4GB kernel). I copied reiserfsck via floppies to the ext2 filesystem on /dev/hda1 (using a rescue system, Suse's did not work because of too few memory). I booted the Suse bootdisk (Suse kernel 2.4.18-4GB), loaded the reiserfs module, went to the console, mounted /dev/hda1 and executed reiserfsck as reiserfsck --check --logfile check.log /dev/hda2 It reported (I've to type from the screen): reiserfs_open: neither new nor old reiserfs format found on /dev/hda2 reiserfsck: could not open filesystem on "/dev/hda2" "echo $?" reported 0 as exit status, check.log has size 0. According to the man page, reportig 0 as an exit status in this case is a bug: man reiserfsck says: 2. Run reiserfsck --check --logfile check.log /dev/hda1. If reiserfsck --check exits with status 0 it means no errors were discovered. reiserfsck --rebuild-tree --logfile rebuild.log /dev/hda2 reiserfs_open: neither new nor old reiserfs format found on /dev/hda2 reiserfsck: could not open filesystem on "/dev/hda2" rebuild.log has size 0. Trying to mount /dev/hda2 with mount /dev/hda2 /mnt2 gives the following kernel messages on the console: ... VFS: Can't find ext2 filesystem on dev ide0(3,2) read_super_block: can't find a reiserfs filesystem on (dev 03:02, block 64, size 1024) read_super_block: can't find a reiserfs filesystem on (dev 03:02, block 8, size 1024) ... I think reiserfsck should do _something_. man reiserfsck says: 6. If the --rebuild-tree step fails or does not recover what you expected, please submit this as a bug report. Try to provide as much information as possible and we will try to help solve the problem. The --rebuild-tree step failed and did recover absoulutely nothing, so I report this as a bug. I suspect the magic number of the reiserfs filesystem is overwritten and reiserfsck gives up. But there really _is_ a reiserfs filesystem on that partition. I'll save the first 1.4 MB of /dev/hda2 on a floppy for further analysis, if required. Please CC me, as I'm not on the [EMAIL PROTECTED] Thank you, Moritz -- Dipl.-Phys.
