LXD version 3.18, using snap. I have one storage pool set up, the default zfs pool. I’m running Ubuntu 18.04 and only using the computer for running the containers.
The disk space used by the ZFS pool is increasing by 4-5 GB per day. Nothing in my containers should be generating anywhere near that amount of data, and when I check the amount of space used by all containers it is very small.
> df -h . Filesystem Size Used Avail Use% Mounted on /dev/sda2 458G 94G 341G 22% / > sudo du -sh /var/snap/lxd/common/mntns/var/snap/lxd/common/lxd/disks 83G /var/snap/lxd/common/mntns/var/snap/lxd/common/lxd/disks > zpool list NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT default 186G 5.41G 181G - 11% 2% 1.00x ONLINE - > zfs list NAME USED AVAIL REFER MOUNTPOINT default 5.41G 175G 24K none
I went through and added up the usage of every container using
sudo du -hs /var/snap/lxd/common/mntns/var/snap/lxd/common/lxd/storage-pools/default/containers/<container>/rootfs
and it was about 11GB.
As a test I stopped all but one container for about 9 hours. The size of the container grew by about 10MB, but disk usage grew by 1.8GB.
Any ideas about what could be going on?
