Public bug reported:
Hi, I encounter issue when I manually override the disk size. I got real
ZFS backed pool
The snap version is 5.0.3 from 5.0/stable channel
$ snap info lxd |grep install
installed: 5.0.3-babaaf8 (27948) 91MB -
When specify 24GB it's ok
mastier@drakkar:~$ lxc init ubuntu:22.04 testvm --vm -c limits.cpu=1 -c
limits.memory=2GiB
mastier@drakkar:~$ lxc config device override testvm root size=24GB
Device root overridden for testvm
mastier@drakkar:~$ lxc config device list testvm
root
mastier@drakkar:~$ lxc start testvm
mastier@drakkar:~$ lxc exec testvm bash
root@testvm:~# df -h

exit
mastier@drakkar:~$ lxc delete --force testvm
When I set 15 or 16GB.
mastier@drakkar:~$ lxc init ubuntu:22.04 testvm --vm -c limits.cpu=1 -c
limits.memory=2GiB
Creating testvm
mastier@drakkar:~$ lxc config device override esa-vpn root size=15GB
Error: Failed to update device "root": Failed to run: zfs set
volsize=15000002560 rpool/lxd/virtual-machines/esa-vpn.block: exit status 255
(cannot set property for 'rpool/lxd/virtual-machines/esa-vpn.block': 'volsize'
must be a multiple of volume block size (16K))
mastier@drakkar:~$ lxc config device override testvm root size=16GB
Error: Failed to update device "root": Failed to run: zfs set
volsize=16000000000 rpool/lxd/virtual-machines/testvm.block: exit status 255
