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.
