How To Monitor PassthroughDisk In VM

[qlozin]

Hi,
I am new to promox VE. Sorry for my foo question.

I have a LSi 2308 SAS Controller to manage some disks. (Most people don't use this. But second hand SAS disk are cheaper.)

And using qm set 101 -scsi1 /dev/disk/by-id/XXXX to pass-through a disk.

I want to monitor disk status in 101, but there's no data (such as 0℃ temperature result) and it's working in promox.

101: smartctl -a /dev/sdb

root@nas:~# smartctl -a /dev/sdb

• Is it possible to get disk status in VM?
• Or it's wrong way to pass through a disk ?

I don't want to passthrough all the LSI2308's into the VM.​

promox 8.1.4



Thanks a lot.

As you can see its QEMU passing the disk to VM - so no SMART HW data from disk.
AFAIK only if you passthrough the HW controller is there any chance of getting direct SMART data from disk.
But you should be able to get the SMART data from the host.
So what happens if you check that drive from the host ? So maybe:

proxmox: smartctl -a /dev/sdb

Any alerting etc. can also be done for that drive from host. So I'm not sure why you want it specifically from within the VM.

Thanks for the reply. ❤

I'm trying to build a NAS using openmediavault in VM and there are some great automated alerting solutions inside.

I am new in promox so building lots of service may take mistakes then mass. QAQ

It seems there are two choices: Pass through full control or monitor from host.

Yes, that is pretty much your choice.

However (& I don't use OMV at all); It may be possible (theoretically) to get the SMART data in OMV by getting it through an API/SSH from the Proxmox Host. I can't help you with that - and almost surely it will take a lot of tinkering - not the automated built-in alerts in OMV you are looking at.
