hello listmembers,
it happend that i killed my filesystem, at least its not mountable
anymore and "reiserfsck --rebuild-tree" was not able to finish
and stoped during Phase 1 two times on different computers alltough
the blocks where it finished where not identical it seems to me
the same problem. the filesystem is about 500GB in size.
the following things happened. i had setup a raid6(software) and
put it on 5 disks. one of them had hardware errors and shortly
afterwards anotherone had some problems too. should be no big deal,
as with my setup 2 disks should be able to fail without loss of data.
i had problems reading certain files (not enterable directorys)
what i first did, and thats probably the worst i could do,
is that i reiserfsck't -rebuild-tree on that filesystem. it didnt get very
far (for the defective disks where causing severall hangs) and reiserfsck
exited.
i then removed the faulty disks and added new ones. i run a
rebuild on the raid and after a few hours i thought thats it.
at least mdadm tells me that everything is allright now.
reiserfsck could do its job i thought. the hardware is ok now.
the raid6 works as it should...
has anyone an idea on how i can continue from here ?
some version information: linux kernel 2.6.6, reiserfsck 3.6.19, mount-2.12p
regarding the possibility of hardwareproblems. smart is enabled on all
drives
and there has been no error logged on any of the participating disks.
also syslog doesnt show anything during a run of reiserfsck --rebuild-tree.
thanks for any hints
gerald

** Do not run the program with --rebuild-tree unless **

** If you have bad sectors on a drive it is usually a bad **

** that -- and only then run this program. **
** If you are using the latest reiserfsprogs and it fails **
