Hi there
I am having a slight problem in a test setup, it has eluded me for days.
The case is, I have 2 virtual machines both running Debian linux with kernel
2.6.32-5-686
I have a 3rd VM with windows 2003 and iSCSI initiator v.2.08
These VM's are called SAN02 and SAN03 and WIN
Both Linux VM's have 4 NIC's
Eth0 for management
Eth1+2 for iscsi connectivity
Eth3 for DRBD synchronization.
The windows VM has 3 NIC's
1 for management and 2 for iSCSI connectivity.
DRBD is configured in primary/secondary mode.
Heartbeat seems to detect failover fine if I shutdown SAN02, SAN03 becomes
primary and SAN02 goes unknown.
However when I shutdown SAN02, the iSCSI connectivity from WIN to the iSCSI
device drops.
When I restart the iscsi service on SAN03 the disk reappears on WIN. <- this
should happen without me restarting the service.
Does anyone have a clue as to why I have to manually restart the iscsi service
before things work again? If I turn back on SAN02 while SAN03 is primary, the
same thing happens once SAN02 becomes the primary and SAN03 becomes secondary.
I will have to restart the iscsitarget service on SAN02 and only then WIN
regains the iSCSI disk.
Thank you in advance,
Michael Laursen
