I'm coping a little issue today.
I am running vCenter 5.1 with 2 ESXi hosts running vSphere 5.1 each (vCenter is also in a VM box on one of my 2 hosts)
I've many VM all running Debian squeeze 6.06 (i don't think this is the issue but..)
In one box (running Debain as OS) I've added a virtual disk via vSphere client connected to vCenter.
no pb, it was done in 3 clicks.
After, I wanted to mount it via my debian console with SSH
with something easy like that : mount /dev/sdb /mnt/data
(the first disk is on /dev/sda)
"I got this error message : mount: you must specify the filesystem type"
and even if I specify -t ext3 for example I got that :
Can't I mount my virtual disks this way ?
