Hello, I'm making a simple test with GFS2: I run simultaneously on both nodes, a script that make write operations in the filesystem. It causes GFS2 to dump a stack trace and fault. I have a cluster configured with two nodes like this: Ubuntu 10.04.1 LTS Kernel 2.6.35-23-generic drbd8-source-2:8.3.7-1ubuntu2.1 drbd8-utils-2:8.3.8.1-0ubuntu1 cman-3.0.2-2ubuntu3.1 libcman3-3.0.2-2ubuntu3.1 gfs2-tools-3.0.2-2ubuntu3.1 Is this known? What other kind of information could be useful to help find this issue? Thanks, -- Thiago Henrique STACK TRACE: ################################################################################ /var/log/kern.log: Feb 20 06:29:39 wcluster1 kernel: [142560.304056] INFO: task gfs2_quotad:1813 blocked for more than 120 seconds.
