Hi guys,
i just migrated all of my LXC kontainers from ProxMox 4 to ProxMox 5.
LXC containers work, but I noticed that filesystem limits were not in place. I also noticed that some dataset parameters were missing / different.
My questions are:
1. Can I just set, for these transferred instances while running, volume size as they are set in conf files? Like:
zfs set volsize=250G /rpool/data/subvol-100-disk-1
2. Can / should I just set, for these transferred instances while running, zfs refquota instead of volsize? Like:
zfs set refquota=250G /rpool/data/subvol-100-disk-1
3. Can I just set posix as acltype, while they are running? BTW It seems they are running fine without posix set, but I think these CentOS 7 LXCs should have it set. Like:
zfs set acltype posix /rpool/data/subvol-100-disk-1
Here is how it looks when there are no disk limits:
On the old system there was a 250GB limit for this particular instance. On new there is not.
I think it might be related to volsize or refquota parameter. I guess I can just set it manually and PM HTTP GUI as well as instance itself will start showing the limit.
Relevant differences are:
refquota -> old: 250G new: none
acltype -> old: posix new: off
Here are all parameters for one of the datasets. I guess others are the same, didn't check.
