we move 12 KVM's from drbd to nfs storage.

now we have storage unstability.

for instance:
1 - after migrations we have had 4 corrupt file systems and 2 systems with broken mysql tables.

2- when I tried to add a 2-nd nfs mount [ to test using ssd drives ] , the 2-nd mount in pve shows all the 1-st mount's info. from size to content.

I can supply a lot more detail .

I've a question - is anyone using nfs + drbd and having no issues? If not I'll assume we've something basic wrong with our set up.
 
I don't have DRBD backed NFS shares, but if it's any help I use NFS shares on ZFS storage successfully, but I think you have a much more involved implementation than I do just yet. Wish I could be more help.
 
we used zfs in the past for backups , and I still use at home with zfsonlinux on a pve system. I like zfs , storage is very reliable and easy to maintain, however the systems were not highly available.

nfs using zfs and linux both give us issues during backups or heavy network loads .

so there are either nfs configuration issues and or we need a better network set up. we have inifiniband nics and a switch on order..
