I have two ovh dedi server. When I store backup to second disk it runs ok. But if I mount NFS share and store backup there, I see high IO delay thus Kvm hangs. And I have to stop backup.

Any idea?
 
The NFS server is too slow and/or unreliable under load. I see this on many OVH setups.
 
Ftp mount is for also better and fast. I did not notice any slowness but with that it just hangs in any point of completetion. One thing o noted it, with ovh os templates, files system is ext3 with iso install it is ext4. So first I am going to try with iso install and if it still fails will go back to pve 3. Because I do not think it is ovh releated issue.
 
There is absoletly something with version 4.2 Because all went very good with version 3. I tried extfs3 but did not help. I do not want to swtich to v3. Can you suggest something :)
