[Bug 1559723] Re: soft lockup during btrfs balance
As described in my previous comment, the fs was available in read-write mode again. I added another disk to the btrfs and with the additional space I was able to rerun and successfully finish the btrfs balance operation (as described in https://www.slicewise.net/debian/balancierung-eines-vollen- btrfs-dateisystems/ ): btrfs balance start x Done, had to relocate 2797 out of 2797 chunks So my file system is completely rescued now. To sum it up: There is no way I could reproduce this error again with a recent kernel. All I can say is that Kernel 4.2.0-27.32~14.04.1-generic 4.2.8-ckt1 ran into unexpected behaviour when doing a btrfs balance: Expected Result: Error "enospc errors during balance" (at least) Actual Result: Kernel bug in dmesg, Filesystem goes read-only, Input/Output errors occur, many directories are not readable even in read-only mode, even ls does not work. It seems as if the system totally screwed it up. Suggested Fix: All of these problems should be avoidable because the later reboot "healed" them (Error "enospc errors during balance" reported, fs mounted read-write, but btrfs balance still fails, which is totally fine at this point) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1559723 Title: soft lockup during btrfs balance To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1559723/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1559723] Re: soft lockup during btrfs balance
I rebooted the system in the meantime. It now had Kernel 4.2.0-30.36 from previous updates: cat /proc/version_signature Ubuntu 4.2.0-30.36~14.04.1-generic 4.2.8-ckt3 During the reboot, the system performed some disk I/O for several hours. Before services like sshd became available. I guess this disk operation happened before the file system was mounted in read-write mode. What I can say is that the system tried to continue the failed balance operation during the boot (from syslog) without intervention from my side: BTRFS info (device dm-0): continuing balance BTRFS info (device dm-0): relocating block group 9553211031552 flags 36 found 106150 extents The btrfs balance operation did not succeed again, but in a manner which I was used to before writing this bug report. This is MUCH better than going into an unpredictable state (ro mode with Input/Output errors). I guess the OS totally got out of sync. BTRFS info (device dm-0): 2 enospc errors during balance The btrfs file system was mounted in READ-WRITE-mode this time (not in read-only mode as before!). And this time, I can read the files and navigate through directories without any Input/Output errors (before the reboot, I had lots of them!). Finally, everything looks fine for a btrfs file system with no space left on the disk. Now that the fs is online and accessible, I can try to add another disk to the fs to have some empty space again. After that, I hopefully can delete some data and hopefully redo the btrfs balance operation. /var/log/syslog gives me: Mar 22 12:42:37 server kernel: [ 3481.725273] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

[Bug 1559723] Re: soft lockup during btrfs balance
For my setup, btrfs file system runs on top of a LUKS encrypted partition which itself is on top of a mdraid (mirroring). The Layout is: # lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:00 2,7T 0 disk ├─sda1 8:10 7M 0 part ├─sda2 8:20 286M 0 part /boot └─sda3 8:30 2,7T 0 part └─md0 9:00 2,7T 0 raid1 └─md0_crypt (dm-0) 252:00 2,7T 0 crypt sdb 8:16 0 2,7T 0 disk ├─sdb1 8:17 0 7M 0 part ├─sdb2 8:18 0 286M 0 part /boot2 └─sdb3 8:19 0 2,7T 0 part └─md0 9:00 2,7T 0 raid1 └─md0_crypt (dm-0) 252:00 2,7T 0 crypt The btrfs filesystem does not use btrfs-raid functionality. Scenario: 3 hosts are backed up using rsync and btrfs-snapshots on this server. I have 3 groups of subvolumes with about 50 snapshots in each group. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1559723 Title: soft lockup during btrfs balance To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1559723/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1559723] Re: soft lockup during btrfs balance
Note that some months ago (when I got the error message), I still was able to cleanly free up some diskspace and perform a clean btrfs balance (which freed a lot of space). My hope was that I'd get an error message and exit cleanly if disk space is missing. Instead, I got the soft lockup. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1559723 Title: soft lockup during btrfs balance To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1559723/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
