Hello, I have a filesystem that has become unusable because of a balance I can''t stop. It is very close to full, and the balance is preventing me from growing it. It was started like this: sudo btrfs filesystem balance start -v -musage=60 -dusage=60 /srv/backups It has been stuck at 0% across reboots and kernel upgrades (currently on 3.8.1), and cancelling it had no effect: Balance on ''/srv/backups'' is running 0 out of about 5 chunks balanced (95 considered), 100% left According to atop it is writing but not...

Hi. I''m considering an imminent switch from ext4 to btrfs and I''m hoping that someone can lend me advice before I do something unsupported. I have a software raid 6 array configured via mdadm.

Hello list, recently reformatted my home partition from XFS to RAID1 btrfs. I used the default options to mkfs.btrfs except for enabling raid1 for data as well as metadata. Filesystem is made up of two 1TB drives. mike@mercury (0) pts/3 ~ $ sudo btrfs filesystem show Label: none uuid: f08a8896-e03e-4064-9b94-9342fb547e47 Total devices 2 FS bytes used 888.06GB devid 1 size 931.51GB used

I already posted this in the thread "ENOSPC with mkdir and rename", but now I have a device with 100GB unallocated on the "btrfs fi sh" output, and when I run a rebalance of the form: > btrfs filesystem balance start -dusage=50 -musage=10 "$mount" I get more than 75 of such stack traces contaminating the klog. I've put some of them up in a gist here: https://gist.github.com/pwaller/1df8a7efc2f10343f2e3 and one of them is reproduced below. Is this harmful or expected? Are there any workarounds? Thanks, - Peter [...
