I am running OVM 3.1.1 connected to an EMC storage array. I have a situation where physical disks are being used for OS and binary filesystems (i.e. /u01, etc..) rather than virtual disks inside a repository. When a VM is migrated from one host to another, I sometimes get a message stating the size of the disk changed and shortly afterwards the filesystem is changed to read only and I have to reboot to fix the problem. Is this an unsupported configuration or do I have potential problems with my LUN mapping? Has anyone seen this problem before?
