Anybody can help? How to configure MSA2050 on another nodes? It works only on first :( Disk view on first node (working) And on second (mulitipath -ll shows nothing)

Something wrong again. I've configured 2 nodes and it worked (even with working vm with storage on msa). Today I've noticed that msa storage on second node has question mark. I totally don't know why - pve shows nothing on `multipath -ll` command, there is no volume group on node 2, too. I have...

Thanx

I've connected MSA2050 to Proxmox, it works, I can create vms but I've got error while migrating disk from another node: TASK ERROR: storage migration failed: target storage is known to cause issues with aio=io_uring (used by current drive) What to do to fix it?

Ok, thanx. Now it's completely clear for me.

Can you explain me how to set up 3 nodes with working live migration? Every node has own storage but live migration needs the same name storage on all nodes. It's not possible to add the same name storage more than once.

ok, I got it. It was easy.

1. I've done it 2. I've installed multipath-tools and multipath-tools-boot and lsscsi shows such state: [1:0:0:0] enclosu HPE MSA 2050 SAS V270 - [1:0:0:1] disk HPE MSA 2050 SAS V270 /dev/sdd [1:0:1:0] enclosu HPE MSA 2050 SAS V270 - [1:0:1:1] disk...

Hello, you told that's pretty much plug and play. But not for me, I think. Could you explain it to me shortly?

Lvm is not shared storage "by design". But sas is shared, why?

Thanks a lot for your very comprehensive answers.

I need shared storage but network independent. That's why I have chosen sas array.

Ok, thanks. Indeed, I have to read about SAS. I thought it's simple as NFS attaching

Is SAS connected as ISCSI?

So I can create lvm and attach it to 4 nodes?
