Greetings to all! I'm jumped by some week in the Proxmox world, i'm
still experimenting a bit doing some test P2V migration, so, excuse me
if ask dumb question...
As stated in subject, my system (for now two nodes, HP ProLiant ML150
Gen9) use the SAN HP MSA 1040; that SAN have two controller, with two
network port (gigabit ethernet, in mine) per controller.
To provide redundancy and more bandwidth, i use 'multipath', configured
following the wiki:
First note:that wiki page i think misses a note: you have to create a
LVM on the iSCSI target (creating it before adding to multipath conf)
or doing by hand, as found here (#12):
All works like a charm, but i have two little trouble, and i've not
found in wiki info about.
1) probably not a proxmox issue, but... if i reboot a node, sometime
multipath does not setup correctly. A simple 'systemctl restart
multipath' fix the issue but... i think there's some parameter i can
tweak to behave correctly.
In the meantime, i've put the restart on rc.local.
2) i've not found a way to setup correctly the volume to accept .qcow
disks, eg i've followed:
but the volumes created accept only RAW disk format.
There's some way to make a iSCSI target accept other format?
