* [Cluster-devel] [GFS2 PATCH] - Bug 675944 - gfs2 quota allows exceeding hard limit [not found] <2128286308.330630.1299598759037.JavaMail.root@zmail05.collab.prod.int.phx2.redhat.com> @ 2011-03-08 15:40 ` Abhijith Das 2011-03-09 9:58 ` Steven Whitehouse 0 siblings, 1 reply; 2+ messages in thread From: Abhijith Das @ 2011-03-08 15:40 UTC (permalink / raw) To: cluster-devel.redhat.com Immediately after being synced to disk, cached quotas are zeroed out and a subsequent access of the cached quotas results in incorrect zero values. This meant that gfs2 assumed the actual usage to be the zero (or near-zero) usage values it found in the cached quotas and comparison against warn/limits never triggered a quota violation. This patch adds a new flag QDF_REFRESH that is set after a sync so that the cached quotas are forcefully refreshed from disk on a subsequent access on seeing this flag set.
