[pve-devel] Default cache mode for VM hard drives

Hello,

It seems many people who use DRBD doesn't change cache mode and doesn't
check DRBD consistency and then blame DRBD or even Proxmox for instability
and FS corruptions.

What about an option to set default cache mode for a specific storage type
(for example "writethrough" for DRBD and "none" for local and others)? Or
even global default option would be helpful, so we could change it to
writethrough or directsync and then use "none" only if we "know what we are
doing".

Best regards,
Stanislav
