Open-iSCSI Interface by libvirt
While I was introducing an iSCSI pool to libvirt with KVM, a new
interface was introduced to Open-iSCSI called libvirt-iface-*
, with the
effect that LUNs were no longer detected after target login.
It took nearly an hour to analyze the reason for this failure, the initiator ID changed and the default CHAP login was not set for this interface, thus the iSCSI LUNs failed.
The following approach solved the problem on each KVM host:
- Remove the interface definition from
/etc/iscsi
. - Remove all node and target definitions containing the libvirt
device name from
/etc/iscsi
. - Reboot
- Introduce the iSCSI targets before binding them to a pool in libvirt.
