<div>There's issue with NFS: if you try to
send over it more than network can deal with (100-120 MBps for
1-gigabit), it imposes several-second pauses, which are being
interpreted like hardware errors. These bursts may be just few
seconds long to trigger issue.<br>
<br>
You can try to limit bandwidth in virtual HDD config to something
like 60-70 MBps. This should be enough for 1-gigabit network.<br>
<br>
But my opinion is that it's better to switch to iSCSI.<br>

I wonder why I have others VM, as I said
before, with Ubuntu, CentOS, Windows 7 and

Not of all have huge big files or a lot of
connections, but they stand solid!<br>
</div>
But when require a lot access and deal with
big files, here's came the devil! The VM just
get IO error and die before 2 or 3 days...<br>
</div>
On both physical servers, not hight load. I
check with HTOP and TOP as well.<br>
</div>
iostat doesn't show nothing wrong.<br>
</div>
In side the VM, a lot I/O error from time to time...<br>
</div>
IO goes high endeed, but is so expect because I am
using imapsync to sync mails to old server to Zimbra
Mail Server...<br>
</div>
But I do not expect the VM die with IO errors!<br>

It's so frustrating... :(<br>

<div>What's virtual HDD config? Which
controller, which cache mode?<br>
<br>
I suppose it's bad idea to run KVM machines
via NFS: it may produce big enough delays
under high loads, which may look like timeouts
on client side.<br>
If you want some network storage, iSCSI can be
better chiose.<br>

Proxmox server is
a PowerEdge R430

Storage is the same

there's a cable in order

In second server, I have

in /data FS.<br>

In the same server, I have
NFS installed and server FS
to Proxmox machine.<br>
</div>
In proxmox machine I have
nothing, except a VM with
Ubuntu 14.04 installed, where
Zimbra Mail Server was
deploy...<br>

Inside bothe physical servers,
everything is ok... NO error in
disc and everything is running
smoothly.<br>

But, INSIDE THE VM HOSTED WITH
PROXMOX, many IO errors!...<br>

This make FS corrputed in some point
that make Zimbra crash!<br>
