For example SLES 11 SP 2. A Linux training VM image I developed some slides about implementing an OpenLDAP server in SLES with on the next day was totally broke: - no space left on device - snapper created tons of snapshots - yet in df -h still 2 GB free - rm on a logfile returned no space left on device - btrfs subvol delete returned no space left on device - I think I also tried btrfs balance with no space left on device, but I am not 100% sure At that time I just created a snapshot of the broken state and returned to a previous snapshot to have the VM fixed. And note: This is on a distro that has enterprise support for using BTRFS on root filesystem – while using a 3.0 kernel, with hopefully some… but apparently not enough backports. Granted, still it would be nice to to add a warning to Debian. Better still would be just to have stability fixes for the hangs go into 3.16- stable and thus also into Debian Jessie. -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7
