Is it possible to convert an existing ISPconfig installation to btrfs without problems with quota? UUID = DISKID / ext4 errors = remount-ro, usrjquota = quota.user, grpjquota = quota.group, jqfmt = vfsv0 0 1
Btrfs does not support traditional Linux user-based quota, so quota for websites will stop working when you convert the filesystem to btrfs.
Sorry for my late response. My English is unfortunately not the best, but I do my best. ZFS has a kind of quota, but I don't think it's exactly what ispconfig needs. Unfortunately I only found old forum posts that concern this topic. It would certainly be good if ISPConfig e.g. Would support ZFS or btrfs. The filesystems don't seem bad.
