Looking for a bit of help getting this FS balanced. I'm getting a kernel crash and readonly file system error: [ 9357.096562] Workqueue: btrfs-extent-refs btrfs_extent_refs_helper [btrfs] dmesg output. http://pastebin.com/c9xKvpZ0 This problem began because of performance issues. Basically the FS appeared to be hung. (I think because it got to about 100GB free) I added a drive and started a rebalance which somehow also hung. I then aborted the whole thing, upgraded from 4.3 to 4.4 and after a long wait the FS mounted. I deleted more snaps and now when I start a balance, the FS goes read-only. Thanks for any help you can provide! -Brendon # uname -a Linux humvee 4.4.0 #1 SMP Thu Jan 14 15:54:03 PST 2016 x86_64 GNU/Linux # btrfs --version btrfs-progs v4.3 # # btrfs fi show Label: 'tank0' uuid: d25217dd-91f1-4add-8c07-66eacff9fb28 Total devices 6 FS bytes used 6.22TiB devid 1 size 3.64TiB used 3.52TiB path /dev/sdc devid 2 size 3.64TiB used 3.52TiB path /dev/sdd devid 3 size 3.64TiB used 3.52TiB path /dev/sde devid 4 size 3.64TiB used 3.52TiB path /dev/sdf devid 5 size 3.64TiB used 3.52TiB path /dev/sdg devid 6 size 3.64TiB used 1.00GiB path /dev/sdh btrfs-progs v4.3 # # btrfs fi df /tank0 Data, RAID6: total=10.55TiB, used=6.21TiB System, RAID6: total=96.00MiB, used=880.00KiB Metadata, RAID6: total=19.59GiB, used=10.34GiB GlobalReserve, single: total=512.00MiB, used=0.00B # -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
