Configuring multipath ISCSI pools in virt-manager, cockpit or libvirt
Environment
- Red Hat Enterprise Linux 7, 8 and 9
Issue
- Currently Referring to Creating iSCSI-based storage pools using the CLI . If the parameter /dev/disk/by-path is used, then for each LUN only one path can be imposed.
- Whats the solution to use iSCSI LUN with multiple paths as a Storage Pool with virt-manager?
Resolution
- Configuring iSCSI Pools with multipath pools is currently not available. Currently only single path can be configured to create an iSCSI pool.
- The solution is to configure the iSCSI multipath storage separately from the virtualisation components, and then use the /dev/mapper/xyz device as the source of a Virtual Machine disk directly on the Guest XML definition, bypassing libvirt storage pools.
