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.                 **

so now i am stuck with a root block error

 

root@R2D2:~# reiserfsck --check /dev/sdg1

Will read-only check consistency of the filesystem on /dev/sdg1

Bad root block 0. (--rebuild-tree did not complete)

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?

HAHAHa  it is in the title as asked for in the subforum description

6.3.2

 

quote -> Please prefix your post with the specific version of unRAID OS in use.

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.

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
