Subject: XFS preallocation with lot of small objects
Date: Wed, 11 Dec 2013 11:24:23 +0400 [thread overview]
Message-ID: <52A81327.1000402@xdel.ru> (raw)
Hello,
Due to lot of reports of ENOSPC for xfs-based stores may be it worth to
introduce an option to, say, ceph-deploy which will pass allocsize=
param to the mount effectively disabling Dynamic Preallocation? Of
course not every case really worth it because of related performance
impact. If there is any method to calculate 'real' allocation on such
volumes, it can be put to the docs as a measurement suggestion too.
