Date: Sun, 9 Jan 2011 22:06:42 +0100 From: Nikola Ciprich <extmaillist@...uxbox.cz> To: cluster-devel@...hat.com, Linux kernel list <linux-kernel@...r.kernel.org> Cc: nikola.ciprich@...uxbox.cz Subject: 2.6.37 - GFS2 trouble Hello, I wanted to try 2.6.37 on my cluster, but all tasks trying to access GFS2-mounted partition got stuck. Kernel started spitting following messages: Jan 5 22:16:46 vbox1 [ 3001.948125] INFO: task gfs2_quotad:12532 blocked for more than 120 seconds.
