high avalability of storage daemon

[GB]

Hi, I have a fibre channel multi drive tape libary and would like higher avalability.

the tape drives have an A and B fibre port

I have two servers I can use as storage daemons for this single storage resource

server 1 is connected directly to the FC A ports on the drives

server 2 is directly connected to the FC B ports on the drives

What is the conventional way to do this setup?

 Currently I am thinking of using pacemaker to have a floating IP between the servers and a single storage daemon running

On failover the current job will be cancelled but I dont see a way around this - using a single virtual machine is not going to work with pcie passthrough or host device passthrough with my hypervisor

I could set up the tape drives to be assesable over iscsi initators as another way and put the storage daemons on the director VM but this seems more compelx and risky.

details on sharing tape over iscsi here

Anyone done a similar setup? any advice?

My method of doing this was creating an IP per storage resource (tape libary)

  SDAddresses  = {
    ip = { addr = XXX.XXX.XXX.XXX; port = 9103; }
  }

and creating a systemd resource for each storage daemon. Then the nodes share an IP
