Hallo,
next problem (sorry):
my cluster of 3 2-TByte-disks has some damaged files. When I try to
delete the directory entries with the "midnight commander" (via
"putty",
over the LAN) then "mc" hangs. Killing the putty session and opening
(via "putty") a new "mc" window shows that the directory
entry doesn''t
exist - looks good.
Mountpoint is "/mnt/btr".
lsof /mnt/btr
still shows a "mc" entry which I can''t remove with
"killall -9 mc" or
"kill -9 <mc-PID>".
And more bad:
reboot
doesn''t work,
Ctrl Alt Delete
(on the machine, not over LAN) doesn''t work too.
I have to restart the machine via main power switch - no good job.
Viele Gruesse!
Helmut

Hello Helmut! I''m having the same observation currently: There are bad files in my $HOME and I can''t delete them because it makes the kernel ooops. I tried Josef''s repair program but it fails an assertion. What''s your kernel backtrace? Did you try the repair program? Maybe we really got the same problem and could combine efforts? I filed an issue here: https://github.com/josefbacik/btrfs-progs/issues/1 Helmut Hullen wrote:> Hallo, > > next problem (sorry): > > my cluster of 3 2-TByte-disks has some damaged files.

Hello, I had a similar problem. Some files (2-3) got corrupted in my /home subvolume for no apparent reason. Trying to access the files gives kernel oops. Sometimes it freezes the machine, sometimes I am back to my console without any problems. Then I switched to the latest 3.1rc and freezes were gone (though I still had the kernel oops). (I did not try the repair program fearing that it would do more bad than good. After all, my / subvolume was fine and i still could mount /home) But to tackle the problems with corrupted files I had to create a new subvolume for /home, tranfer the files from the old one (minus the corrupted files) and delete the old subvolume. Though still btrfsck would give me errors trying to access some inode. But I could mount and use all my subvolumes with no problems. Then... I re-created btrfs with the latest btrfs-tools and installed the latest 3.1rc from the very beginning. So far, it is working fine and the situation with disk I/O has greatly improved. I think you may want to try to upgrade to the latest 3.1rc and at the very least you (hopefully) should not be getting hard freezes any more. best ~dima -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
