Hello, I have trouble to mount a reiserfs 3.6 filesystem after a power loss. It is living on a md raid1 (2xSATA) with cryptsetup. I have used this setup for years without any problem so far. With "strings" I see data and text inside the /dev/mapper/... device, so it seems the data could be intact. [139977.209415] REISERFS (device dm-2): found reiserfs format "3.6" with standard journal [139977.209852] REISERFS (device dm-2): using ordered data mode [139977.214845] attempt to access beyond end of device [139977.214858] dm-2: rw=0, want=18401083744, limit=1781801088 [139977.214870] REISERFS warning (device dm-2): sh-459 journal_init: unable to read journal header [139977.247350] REISERFS warning (device dm-2): sh-2022 reiserfs_fill_super: unable to initialize journal space I found also a mail with similiar content from 5/2009 but no solution: http://marc.info/?l=reiserfs-devel&m=124143380020910&w=2 I can break the mirror and experiment with the second copy. The System is Debian: # uname -a Linux k8 2.6.32-trunk-vserver-amd64 #1 SMP Sun Jan 10 23:45:41 UTC 2010 x86_64 GNU/Linux # fdisk -l /dev/sda Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xff7911e5 Device Boot Start End Blocks Id System /dev/sda1 * 1 3917 31463271 7 HPFS/NTFS /dev/sda2 3918 10445 52436160 83 Linux /dev/sda3 10446 10689 1959930 82 Linux swap / Solaris /dev/sda4 10690 121601 890900640 fd Linux raid autodetect #fdisk -l /dev/sdb Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00f7cee4 Device Boot Start End Blocks Id System /dev/sdb1 1 3917 31463271 b W95 FAT32 /dev/sdb2 * 3918 10445 52436160 83 Linux /dev/sdb3 10446 10689 1959930 82 Linux swap / Solaris /dev/sdb4 10690 121601 890900640 fd Linux raid autodetect sda4 + sdb4 are the mirrors. My Steps so far: 1) I tried to reiserfsck with --check, result: bread: Cannot read the block (2535232620): (Invalid argument). reiserfs_open: Your partition is not big enough to contain the filesystem of (2535232620) blocks as was specified in the found super block. Failed to open the filesystem. If the partition table has not been changed, and the partition is valid and it really contains a reiserfs partition, then the superblock is corrupted and you need to run this utility with --rebuild-sb. 2) next --rebuild-sb and then --check tells me to run --rebuild-tree. After # reiserfsck --rebuild-tree most of the files are gone. 3) I will just try to recover with the -S option, but I hoped to get the directory structure intact without any files in lost+found. Any advice?
