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

I have an update on this issue.

I have found circumstances when we get out of sync with directsync mode and
made more test. What I found out so far was that out of sync only appear
for cache modes with O_DIRECT, i.e. for those cache modes when host cache
is bypassed. Write-back and write-through modes do not produce out of sync
blocks with DRBD while "none" and "directsync" do.

Best regards,
