159G lxd_build_479507499

Is it safe to delete lxd_build_479507499 ?

Ok smart people, I know I should have put /var in another partition… my bad


Ok I know what happen: the lxc publish is using the file in the export of my container when i do backup at night …

Is it possible to change the default location of this file ?

You can use the storage.images_volume and storage.backups_volume keys to store the backups/ and images/ directories in a volume on your storage pool rather than directly on your system’s main partition.

I am using zfs has the backend,
I have created 2 new pool and then 2 new volume

lxc storage create bkp_pool zfs source=tank/bkp_pool
lxc storage create img_pool zfs source=tank/img_pool
lxc storage volume create bkp_pool bkp_vol
lxc storage volume create img_pool img_vol

lxc config set storage.backups_volume bkp_pool/bkp_vol
Error: Storage volume “bkp_pool/bkp_vol” isn’t empty

lxc config set storage.images_volume img_pool/img_vol
Error: Storage volume “img_pool/img_vol” isn’t empty

Is this a new bug or am I missing something.

I could use type dir to a zfs volume, but why should I ?

That might help !!!

That certainly does feel like a bug

Running 3.23 !

Please let me know if you want me to test or give you more information or even upgrade to 4.0 ?


I don’t know why 4.0 would be any different but at the same time I’ve not been able to reproduce your issue here on 4.0 with zfs, so who knows :slight_smile:

ok i Will attemps upgrade on the weekend and let you know

Do you have snapdir enabled globally or something like that?

Yes !

Try turning it off on those particular datasets see if that fixes it?

It work ! :frowning: sorry for that
