you may want to remove old snapshots (snapper list and snapper remove 2-last number) and issue e.g. manually (is done by cron job as far as I remember) btrfs fi balance start -musage=55 / btrfs fi balance start -dusage=55 / This normally helped with me. But with 30 Gb root I regularily ran out of space with btrfs. Cheers. On Mittwoch, 29. Juni 2016 21:52:01 CEST Francesco Montesano wrote:
Hi all,
When the big update with the gcc6 arrived I did my usual dist-upgrade. Despite having at least 7Gb of free space on /, it took me 3 or 4 attempts to finish the installation because of "no space left on device". With a combination of removing some file in /tmp, logout-login and some waiting I managed to install all the packages and rebooted.
But then I started getting "no space left on device" for no apparent reason (I've also rebooted a couple of times in the meanwhile). I randomly get it e.g. when trying to install something with pip, doing tab-completion on bash or using sudo. Often after a few minutes the problem disappears by itself for some time. Today I was trying to create a python virtual environment and got this: OSError: [Errno 28] No space left on device: '/usr/tmp/tmpzrux9b_p'
I have no idea of what is going on, as I have plenty of space available. This is the situation now, but haven't changed much in the last week (I still haven't pull the last two updates):
~> df -h /dev/sdb2 41G 33G 7.2G 83% / [...] ~> btrfs filesystem df / Data, single: total=38.23GiB, used=31.09GiB System, single: total=32.00MiB, used=16.00KiB Metadata, single: total=1.75GiB, used=1.30GiB GlobalReserve, single: total=448.00MiB, used=0.00B ~> du -hs /tmp 47M /tmp ~> du -hs /var/tmp/ 174M /var/tmp/
Is this somehow related with Bug 931571? Where can I get more info about what is going on?
Ciao,
Francesco
