sacretagent Posted March 9, 2017 Share Posted March 9, 2017 (edited) HI , got a reiserfs drive that became unformatted in my tv server did a reiserfsck --check on the disk and it told me that it could be solved with --rebuild-tree but at 15% this stops with a segmentation error..... so did all the obvious things as memory checks and so on but it won't finish the rebuild root@R2D2:~# reiserfsck --rebuild-tree /dev/sdg1 reiserfsck 3.6.25 ************************************************************* ** Do not run the program with --rebuild-tree unless ** ** something is broken and MAKE A BACKUP before using it. ** ** If you have bad sectors on a drive it is usually a bad ** ** idea to continue using it. Then you probably should get ** ** a working hard drive, copy the file system from the bad ** ** drive to the good one -- dd_rescue is a good tool for ** ** that -- and only then run this program. ** ************************************************************* Will rebuild the filesystem (/dev/sdg1) tree Will put log info to 'stdout' Do you want to run this program?[N/Yes] (note need to type Yes if you do):Yes Replaying journal: Done.

(--rebuild-tree did not complete) Aborted root@R2D2:~# is there a way around this? I tried moving the drive to my movieraid server but it hangs at the same point .... so it is disk specific i guess... would like to get to solve the root block error so that i can mount it readable and get the data from it .... is there a way to do so ? i know the data is still there as i did a test with easus data recovery and it finds everything ,,,,, but there has to be a way around this bad root block thing.... it is reiserfsck that sets it when you do a --rebuild-tree so surely it should be solvable? got another disk on my movieraid server which refused to delete some files so again ran check it tells me to run rebuild-tree anf again segmentation fault but this time at nearly the end of the check so now i have 2 disks which are having the root block issue .... this is crazy ... is there a known issue with the current reiserfsck program on our unraids?

JorgeB Posted March 9, 2017 Share Posted March 9, 2017 (edited) doh. Try downgrading to 6.2.4, it uses an earlier reiserfs-progs, I know that helped at least two users that had similar problems. Edited March 9, 2017 by johnnie.black Quote Link to comment
sacretagent Posted March 10, 2017 Author Share Posted March 10, 2017 HI Johnnie, that seems to do the trick... one drive is nearly finished now... the other one has some bad blocks which i am mapping now and then will rerun rebuild-tree does limetech know about this? Greetings Quote Link to comment
