Re: [Xen-users] Disk erros on one xen domain

[Nicolas Michel <nicolas.michel@xxxxxxxxx>]

I know RAID don't guarantee there is no errors.

My two others physical machines that hosts each a Xen domain controller 
are not the same hardware at all but the same OS (Debian Lenny 64 bits). 
They don't have these errors and never crashed.
You think I should try another kernel more up-to-date?
