Hi.
After a lot of questions and answers in this forum, i have now a production cluster of 1 master and two nodes.
But it seems that the whole cluster "hangs" sometimes. it is not accessible through network. ping says destination host unreachable.
exactly at the same time, the /var/log/messages says:
Well i have a 3ware raid 5 on the local harddisks, wihich have write cache enabled. The vm's are on a netapp ISCSI Lun which is accessed through a second LAN interface (VLAN)
The VM's keep on running but the webinterface-konsole just shows a frozen picture for a few seconds, then after the reset (logfile) all seems to be accessible again.
Any suggestions?
