Fwd: btrfs causing reboots and kernel oops on SL 6 (RHEL 6)
Hi, I''m using SL 6 (RHEL 6) and I''ve been playing around with running PostgreSQL on btrfs. Snapshotting works ok, but the computer keeps rebooting without warning (can be 5 mins or 1.5 hours), finally I actually managed to get a Kernel Crash instead of just a reboot. I took a picture of the screen: http://imageshack.us/photo/my-images/716/img0143y.jpg/ The important bits are: IP: [<ffffffffa032c471>] btrfs_print_leaf +0x31/0x820 [btrfs] PGD 0 Oops: 0000 [#1] SMP last sysfs file: /sys/devices/virtual/block/dm-3/dm/name The crashes aren''t predictable either. Like it doesn''t always happen when I do a snapshot or anything like that. Is this a known problem, that is fixed in a later kernel or something like that? btrfs seems cool though, I hope there is something I just misconfiguredĀ or something so that I can get it to be more reliable, although I do acknowledge that this is an experimental filesystem.

If it''s the default SL/RHEL 2.6.32 kernel, then you should try upgrade first. http://elrepo.org/tiki/kernel-ml is a good choice. It''s highly unlikely that anyone would be willing to look at bugs on that "archaic" (in btrfs world) kernel. -- Fajar -- 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

We moved to ZFS in the end, which was able to do the same things we needed btrfs to do.> > -- > FajarCheers, -Joel -- 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
