Thanks, Hi, I've got the same issue. Btrfs FS crashes on my box running Linux 3.11.7. It seems that the crash happens when I start collectd daemon. Maybe a corrupted RRD file somewhere. I don't have time for debugging this issue further so I'm going to re-format this box to ext4. Btrfs is statically compiled in kernel so I'm unable to gdb btrfs.ko. No debug info in kernel image. Sorry not being able to help. /dev/sda2 on / type btrfs (rw,noatime,nodiratime,ssd,space_cache) Mount options used to have also autodefrag but I removed it while hoping it would make the box more stable. # btrfs fi show Label: 'root' uuid: 87943e37-a134-4b8d-bcf2-989334d23b75 Total devices 2 FS bytes used 6.22GB devid 2 size 10.00GB used 9.98GB path /dev/sdb2 devid 1 size 10.00GB used 10.00GB path /dev/sda2 # btrfs fi df / Data, RAID1: total=8.97GB, used=5.99GB Data: total=8.00MB, used=0.00 System, RAID1: total=8.00MB, used=4.00KB System: total=4.00MB, used=0.00 Metadata, RAID1: total=1.00GB, used=234.92MB Metadata: total=8.00MB, used=0.00 A screen grab from the console after the crash happened: http://s3-eu-west-1.amazonaws.com/ilari.stenroth/btrfs-crash-201311/Screen+Shot+2013-11-07+at+9.19.27.png -- Ilari Stenroth
