vm hangs

Hi

I installed ESXi, latest version, all updates done, on a Dell PE2950, with PERC 6i raid controller.

My 4 SATA HDD (750GB) are configured in raid 5 with 2 virtual drive:

vd1: ~ 300 GB where i installed ESXi + datastore1

vd2: ~ 1.7 TB configured as datastore 2

This subdivision is necessary due to 2TB limitation on vmfs file size.

I installed 2 vm (each 8GB long) on datastore 1, and these work greatly.

I also installed a 3rd vm on datastore2. This VM needs all the space available (should work as file server),

so I assign all the datastore2 space (minus 10GB, used for swap & other esxi files).

The problem is that the 3rd VM, running Ubuntu 8.04 server, hangs after doing some I/O on disk (not much, FTP transfer).

The VM console shows a black screen. If I try to reboot this VM, the reboot process stops at 95%, and the unique way to take the control is

reboot all the ESXi.

Any idea?

The hw should be OK, I run the Dell diagnostic CD and didn't find any problem

Regards,

Marco

What about the VM bios option "Large Disk Support" ?

Now is set to "DOS", but the alternative "Other" is suggested for UNIX system
