Hot migration not possible on Promox 6 with ISCSI Storage ?

[Jerome SCHEVINGT]

Hello

Under proxmox 6, 4 clustered servers and a Synology IScsi storage, it is not possible to make hot migration?

hm - sounds like there could be a problem with your multipath setup?
see - https://forum.proxmox.com/threads/c...-while-pvs-appear-on-duplicate-devices.41099/ for a potential explanation

I hope this helps!
