we have 4 ESX 3.5u1-servers with VMotion and DRS activated, on these servers we have a lot of FreeBSD 6.3 amd64 version installed as guests, but when a migration is done from one host to another the servers starts to do an fsck. All disks are placed on a storage so the disks are never moved. We even saw that servers that didn't get moved started to do fsck when another server was moved.
So we have currently turned of DRS and they have stoped doing fsck.
What could be causing this behavior and how can we solve it? We havn't installed VmWare tools.
