OK, there seems definitely to be some kind of bug in reiserfsck 3.6.19. Or is it a feature? ;-) I tried once again with reiserfsck --rebuild-tree to repair the FS and here it is again. About the end of pass 2 (about 20h after starting) counting stopped at "left 32022, 500 /sec" but there was heavy acccess of the drive. After about an hour reiserfsck started consuming 100% CPU and is doning some minimal access to the drive (the drive light blinks every second or so, SCSI reports about 40 commands for each of these accesses). What could be causing this? Is the drive too large for reiserfsck? I wouldn't believe that 0,6TB are but it is consuming at least quite a lot of memory: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 15185 root 39 19 76304 51m 688 R 99.9 10.3 4591:30 reiserfsck I have left it like this the last 3 days just to make sure that it's not my lack of patience. But now still... So any advices? How to find out what is causing reiserfsck to hang? Or would I have to build a debug version and check for myself? The drive itself is working, I checked several times, the server is working all the time as well. Here some reiserfs output it it helps somebody to have an idea: (***snip***) block 125371211: The number of items (1) is incorrect, should be (0) - corrected block 125371211: The free space (0) is incorrect, should be (4072) - corrected block 125506454: The number of items (1) is incorrect, should be (0) - corrected block 125506454: The free space (0) is incorrect, should be (4072) - corrected pass0: vpf-10160: block 129485584: item 2: No "." entry found in the first item of a directory pass0: vpf-10160: block 129485584: item 4: No "." entry found in the first item of a directory pass0: vpf-10160: block 133169584: item 14: No "." entry found in the first item of a directory pass0: vpf-10160: block 133169648: item 25: No "." entry found in the first item of a directory pass0: vpf-10160: block 133170064: item 10: No "." entry found in the first item of a directory pass0: vpf-10160: block 134316400: item 18: No "." entry found in the first item of a directory pass0: vpf-10560: block 145031172, item 7: Wrong order of items - change the obj ect_id of the key [2237738 2237741 0x1 DRCT (2)] to 2237740 pass0: vpf-10160: block 145817616: item 1: No "." entry found in the first item of a directory left 0, 2623 /sec 914346 directory entries were hashed with "r5" hash.
