Hi, we encounter the same "freeze" problem with our dell PE2850 servers (2x Xeon 3 GHz, 4 GB ram, Perc Raid 4/Di (Megaraid), latest FC4 kernel 2.6.13, drbd-0.7.13, latest BIOS & raid firmware) as some other people here. We can reproduce this by: o On secondary: drbdadm invalidate drbd0 o On primary: cat /dev/zero > /drbd/mybigfile The primary system immediately completely freezes (no response to keystrokes, no ping etc.) until manual restart, without any messages on log or console (screen blanking was disabled, so there was really no message). Another oddity after we've done some repartitioning of the underlying disk partitions: When stopping heartbeat on a cluster node (which implies a /etc/ha.d/resource.d/drbddisk stop) some messages like ... drbd_md_sync_page_io ... out of range ... appear on the console. What is this? Any suggestions to solve these problems are welcome. Regards, Markus
