<div class="moz-cite-prefix">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>

<div>BTW, all HD is SAS with gigaethernet between the servers...<br>

I already try with gigaethernet switch in order to isoleted the
Proxmox and Storage from external (LAN) traffic.... Not works at
all!<br>

<div>HDD config is standard... I do not
make any change...<br>
</div>
I wonder why I have others VM, as I said
before, with Ubuntu, CentOS, Windows 7 and
2012, and work fine! <br>
</div>
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>
</div>
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>

To the others:
Yes! Should be

</div>
Proxmox server is
a PowerEdge R430
with 32 GB of
memory.<br>
</div>
Storage is the same
server.<br>
</div>
Both with SAS hard
driver.<br>
</div>
Between this servers
there's a cable in order
to provide a
gigaethernet link.<br>
</div>
In second server, I have
ubuntu 15.04 installed
with DRBD and OCFS mounted
in /data FS.<br>
</div>
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>
</div>
Inside bothe physical servers,
everything is ok... NO error in
disc and everything is running
smoothly.<br>
</div>
But, INSIDE THE VM HOSTED WITH
PROXMOX, many IO errors!...<br>
</div>
This make FS corrputed in some point
that make Zimbra crash!<br>
<br>
</div>
BTW, I will return Zimbra to a
physical machine right now and deploy
lab env for test purpose<br>
