Hey, I''ve a 2x4TB RAID1 setup with btrfs on kernel 3.8.0. Under high I/O load (BackupPC dump or writing a large file over gigabit) I get messages in syslog such as the one mentioned in the subject. The full non-logcheck-ignored log is under [1]. A BackupPC dump between the same exact machines onto a 2TB ext4 volume take 90 minutes on average, the process on the btrfs volume took 465

Running an Ubuntu Raring VM which was built a week ago that is now running 3.8-rc6, I was booting it last night when it hung. After a few forced reboots, it came back up and I found the attached in kern.log. Mostly, the VM has been used for testing anisble deployment, so not a lot of work, just upgrading and installing software, then rebooting. Are these reports useful? Is there any

Hiya, Recently, a btrfs file system of mine started to behave very poorly with some btrfs kernel tasks taking 100% of CPU time. # btrfs fi show /dev/sdb Label: none uuid: b3ce8b16-970e-4ba8-b9d2-4c7de270d0f1 Total devices 3 FS bytes used 4.25TB devid 2 size 2.73TB used 1.52TB path /dev/sdc devid 1 size 2.70TB used 1.49TB path /dev/sda4 devid 3 size

Dear Devs, I have x4 4TB HDDs formatted with: mkfs.btrfs -L bu-16TB_0 -d raid1 -m raid1 /dev/sd[cdef] /etc/fstab mounts with the options: noatime,noauto,space_cache,inode_cache All on kernel 3.8.13. Upon using rsync to copy some heavily hardlinked backups from ReiserFS, I''ve seen: The following "block rsv returned -28" is repeated 7 times until there is a call trace

I''m on Fedora''s 3.8.5-201.fc18.x86_64. I tried to do some not-very-heavy I/O on my system (i.e. save kernel/sys.c in emacs) and it took about a minute. Everything went downhill from there. My system was basically idle at the time. (I have very little in the way of diagnostics because I couldn''t do much but hit the reset button after a couple of minutes.) On

I''ve had a go at determining exactly what happens when you create a filesystem without enough devices to meet the requested replication strategy: # mkfs.btrfs -m raid1 -d raid1 /dev/vdb # mount /dev/vdb /mnt # btrfs fi df /mnt Data: total=8.00MB, used=0.00 System, DUP: total=8.00MB, used=4.00KB System: total=4.00MB, used=0.00 Metadata, DUP: total=153.56MB, used=24.00KB Metadata:

Hallo, linux-btrfs, I''ve (once again) tried "add" and "delete". First, with 3 devices (partitions): mkfs.btrfs -d raid0 -m raid1 /dev/sdk1 /dev/sdl1 /dev/sdm1 Mounted (to /mnt/btr), filled with about 100 GByte data. Then btrfs device add /dev/sdj1 /mnt/btr results in # show Label: none uuid: 6bd7d4df-e133-47d1-9b19-3c7565428770 Total devices 4 FS bytes

Hello, on a fs with 4 disks, raid 10 for data, one drive was failing and has been removed.

If I manually delete the Q35 USB Controllers, I can use managedsave/start, but I start getting tty errors that don't happen before the managedsave/start. Using libvirt 1.2.18 (-1 Arch) and QEMU git-master (2.4.0.r40384.2d69736). Installed using Q35 chipset. I'm running QEMU git, which allows SCSI controller migration, so I can attempt doing this. I started my guest, and waited for 15
