> Steven, is this problem confirmed to rhel6.1?? It seems that I need to downgrade my servers to rhel5.x ... I've opened a support case at redhat for this. While collecting the sosreport for redhat, I found ot in my var/log/message file something about gfs2_quotad being stalled for more than 120 seconds. Tought I disabled quotas with the noquota option. It appears that it's "quota=off". Since I cannot chane thecluster config and remount the filessystems at the moment, I did not made the change to tes it. It might helps you. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
