VMware vSphere/ESX/ESXi makes all writes synchronous.

Thanx for the info. But, there is still a chance that the host environment on which (original poster's) VMware is running uses a lying ATA drive or some other storage that behaves the same as a lying ATA drive.
- I discard a CPU/memory corruption because 8 more VM were running there and start without problem (Windows, not Unix ,Linux or BSD) - Actually i dont know if it is FreeBSD Fault but its curious and dangerous. - Its stock system so, no Async - Any info you need that might be usefull just ask, im here to help and can give you all the info you need - The FSTAB is in the first mail and this report mount
/dev/ad0s1a on / (ufs, local) devfs on /dev (devfs, local, multilabel) /dev/ad0s1e on /tmp (ufs, local, soft-updates) /dev/ad0s1f on /usr (ufs, local, soft-updates) /dev/ad0s1d on /var (ufs, local, soft-updates)
- the machine its actually running from its backup, i have not touched the FSTAB or mount stuff since installation - the machine was installed on VirtualBox then migrated to VMWARE with the convert utility from Virtualbox - SAN Hard drives are all Fibre Channel On Raid 5, fully redundant path, the SAN Switches on the chassis (Enclosure) didn't die when the enclosure start malfunctioning, other SAN applications works without trouble after restart on the same chasis as Virtual machines on the same LUN. the Blades Hard drives are SAS 10000RPM
