Hoi, this is my first post, please be gentle.
I have worked through the manual " reference design and how-to for HA 2-node Xenserver Pool". I followed all installs and configs, except for the fact that do not use Bonded interfaces.
In the final steps I should create a shared iscsi SR, but the floating IP is not online. My DRBD interfcaces have resp 10.10.10.1 and 10.10.10.2 IPnrs, the floating is in iscsi-ha.conf configured with 10.10.10.3.
How and when should this floating interface be online?
Here are my files:
targets.conf:
# Set the driver. If not specified, defaults to "iscsi".
default-driver iscsi
# Set iSNS parameters, if needed
#iSNSServerIP 192.168.111.222
#iSNSServerPort 3205
#iSNSAccessControl On
#iSNS On
# Continue if tgtadm exits with non-zero code (equivalent of
# --ignore-errors command line option)
#ignore-errors yes
