S.M.A.R.T information with HDD passthrough

[lxiosjao]

Hi,

I would like to know why I dont have access to S.M.A.R.T informations from VM when I passthrough HDDs to it.
The scsihw is virtio-scsi-pci (by default)

I use this command :

qm set 102 -scsi0 /dev/disk/by-id/ata-WDC_WD40EFBX

2 questions :
- Why I dont have access to S.M.A.R.T information from VM if it is a HDD passthrough ?
- VM is trueNas and use ZFS : I read that ZFS needs a full access to HDDs to work properly .
Can I have some issue with ZFS if I don't change anything ? It is like using a raid controler with ZFS, right ?

Thanks

full access for ZFS means that you add the whole disk to the pool and not just only a partion or a virtual disk that was created by a hardware raid. The access does not imply that SMART works.

Can I have some issue with ZFS if I don't change anything ?

ZFS does not use SMART, so you will not have a problem here.
