Re: HAMMER filesystem update - design document
:Hi,
:
:I hope this question has not been implicitly answered before, but how
:does Hammer handle quotas? Filesystems like XFS and ZFS maintain quota
:information internally so that a quotacheck after a system crash does
:not take ages. It seems to me that Hammer could manage quotas as a
:part of its cluster allocation strategy. Is this the case?
:
:TIA,
:RIggs
Theoretically a transaction id can be stored along with the quota state
and the quota state can be updated on the fly when a cluster gets
recovered. I wasn't planning on implementing quotas in HAMMER for 2.0
but it's definitely possible to do it without requiring a rescan.
