Hello, we're using gfs2 on drbd, we created cluster in incomplete state (only 1 node). When doing dd if=/dev/zero of=/gfs_partition/file we get filesystem freezes every 1-2 minutes for 10-20 seconds, I mean every filesystem on that machine freezes, doing ls /etc hangs in D state for 10-20 seconds. Sometimes this hang last for more than 2 minutes and hung task message gets logged in dmesg. iotop shows gfs2_logd and flush-XXX:X kernel process taking 99% io resources. GFS is mounted with rw,noatime,nodiratime,hostdata=jid=0 options. gettune options: quota_warn_period = 10 quota_quantum = 60 max_readahead = 262144 complain_secs = 10 statfs_slow = 0 quota_simul_sync = 64 statfs_quantum = 30 quota_scale = 1.0000 (1, 1) new_files_jdata = 0 Server is kernel 3.2.0-25 64bit. What could be the problem? Thank you. Martin -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
