Dear members,
After some weeks to configure 2 proxmox servers + 1 iscsi DELL MD3220i storage array I'm having problems with a testing KVM machine : impossible to start afet a reboot.
Proxmox 2.1 is up-to-date.
So I found some errors :
sda is the local disk.
sdb, sdc and sdd was iSCSI devices used for KVM storages.
Someone has an idea why these errors occurs ?
