Hello,
Has somebody experience with Dell MD3600i and oVirt 3.2.1?
Host and oVirt are deployed on Fedora 18.
My infrastructure contains: 2 x powerconnect 6224 and this storage
with two controllers
Both switch are in stack mode and storage is connect with four 10Gb
ports in same subnet (is better to use it without stack as two subnet?)
So, where is problem...I can create iSCSI storage domain, everything
seems to be OK but when I want to add next host they cannot access
this iSCSI target (in storage management tools is already added to
host group)
And during this process I can see only on host console IO error,
buffer error and kernel BUG: soft lockup -- CPU stuck etc...
Exists recommended way how involved iSCSI?
For the first part I don't have an answer but the softlockups sound
familiar and the only solution I have found sofar that works reliable is
to switch back to kernel 3.6.10
I higher kernel level will sometimes work after a reboot but more often
it will cause softlockups as soon as multipathd is started.
