That's the cause of the error in the guest. You'll have to track
the error<br>
to ESX's management domain. See the logs.<br>
<br>
Does this error come repeatedly? This error is only a problem for
o2hb<br>
if it continues for the next 60 secs. Else it can be ignored.<div><div></div><div class="h5"><br>

Brad,<br>
<br>
I have had the same issue for over a year on ESX
3.5 as well as on vSphere<br>
4.0. I have not tried yet on 4.1. The error
occurs when I put the shared<br>
disk on either SATA or FC LUNs on our SAN. It
also doesn't matter if the<br>
virtual machines are on the same physical host or
not (with independent<br>
disks). The only problem that has come from it is
the occasional reboot of<br>
one of the VMs, which for me is tolerable. I keep
hoping to upgrade to a<br>
new SAN thinking that might fix it. The vSphere
4.0 release IOPS<br>
capability is higher than the SAN (it's 5 years
old) so I didn't think it<br>
was VMware's fault. If you have fairly new
hardware, maybe there is a real<br>
bug somewhere. I don't get I/O errors in any of
my other implementations<br>
on this SAN. I sent a post like yours to the list
when I first built it,<br>
but never opened a bug report with either OCFS or
VMware. If you create a<br>
bug report I could add information from my
implementation as well. (I<br>
actually have two of these setups and they both
have the same errors.)<br>
<br>
Of course, if you find a solution, please post
that as well.<br>
<br>
Thanks,<br>
Kevin<br>
