Adds TrueNASMultipath.pm — a separate PVE storage type 'truenas-multipath'
that inherits all REST API and iSCSI resource management from TrueNAS.pm but
uses iscsiadm + dm-multipath for block device access:
path() → /dev/mapper/<wwid> (NAA from TrueNAS extent)
activate_volume() → iscsiadm login on each portal in truenas_portals;
waits for /dev/mapper device to appear
deactivate_volume()→ multipath flush + iscsiadm logout
qemu_blockdev_options → returns undef (path() used instead)
Packaging:
packaging/DEBIAN-multipath/ — control.j2, postinst, postrm,
changelog.Debian, multipath.conf.example
Distributed via the 'multipath' apt component (ADR-011)
Depends: truenas-proxmox >= 3.1.0, open-iscsi, multipath-tools
CI (build.yml):
- Third staging dir (dist-multipath) and .deb output
- multipath component pool under pool/multipath/v<major>
- Both stable and testing publish steps updated to generate
main + multipath components; Release lists both
- Lint checks TrueNASMultipath.pm and multipath packaging scripts
PoC confirmed 2026-06-07 on pve01-hq against TrueNAS SCALE 24.10:
- Two sessions (172.31.69.91 + 192.168.69.91), both active
- dm-multipath aggregated 3 disks × 2 paths each
- /dev/mapper/mpath* devices appeared correctly
