I want to use btrfs even though it is not "production ready", but I like it for the features zfs is missing (balancing, growing/shrinking volumes, dedup not eating your ram ...).
I wrote 50GB using dd if=/dev/zero and the quota show is showing this now btrfs qgroup show -reF /var/lib/lxd/containers/c1/ qgroupid rfer excl max_rfer max_excl -------- ---- ---- -------- -------- 0/528 2.59GiB 1.72GiB none 20.00GiB so technicaly speaking it is working because excl is smaller then max_excl but in practice 50GB is not smaller than 20GB. I will try to ask in btrfs mailing list. thank you for your help On Tue, Sep 12, 2017 at 9:39 AM, Marat Khalili <[email protected]> wrote: >> so you would recommend ZFS instead? > > > I personally don't use ZFS (it's alien to Linux kernel and I don't want to > deal with support problems arising from this situation).
