multipath.conf and iscsid.conf please (HPE 2060 or similar)

[adobi]

Hi all good people.
I got question, and asking for favour as well. Can anybody share multipath.conf here (and iscsid.conf as well for completely different purposes)
I got a bit of a problem, (not critical this point) I can't reuse vmid until node is restarted. I'm prettu sure I had this right, I went through some of my notes, and now I'm bit lost where might be a problem (guessing is the multipath config).
Any comments appreciated muchly.
All the best

Take a look at https://forum.proxmox.com/threads/langsame-read-performance-me5024-pve.157436/#post-720719 because a me5 is nearly the same as a msa2060 which both are builds by seagate.

correct. all of these cheap arrays using the same software. However, I can't find multipath.conf anywhere in that thread.

Here's one for msa2040 in https://forum.proxmox.com/threads/p...v-with-msa2040-sas-partial-howto.57536/page-2 - and I put a 6 for model 2060 into already.
After installing file (re)start multipathd and check with multipath -ll :

defaults {
user_friendly_names yes
}

blacklist {
device {
product .*
}
}

blacklist_exceptions {
device {
product "MSA [12]0[456]0 SA[NS]"
}
}

just spitballing here, but have you tried the manual?
https://h10032.www1.hp.com/ctg/Manual/c00814876.pdf

but seriously, default multipath.conf should work just fine. I have a corevault (same controller tech) and I didnt have to do any customization.

Understood. Same question again. Can you share your config please?

ok thanks very much.
Your config looks like completely default, looks like I'm "rediscovering the wheel"
Maybe I need to get back to basic config and search problem somewhere else...

What does "multipath -ll" show ?

Understood. Same question again. Can you share your config please?

defaults { 
        verbosity 1 
        path_grouping_policy    multibus  
        find_multipaths smart
        } 

blacklist { 
        devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"    
        devnode "^hd[a-z]" 
        property "ID_ATA" 
}

got a bit of a problem, (not critical this point) I can't reuse vmid until node is restarted.

I dont understand how this is related to multipathing in the first place...
