Proxmox 6.04 I get /dev/sdb: open failed: No medium found /dev/sdc: open failed: No medium found

[webservio]

After researching the threads I still cannot find why after a fresh installation of Proxmox 6.0 I get the following error message:

/dev/sdb: open failed: No medium found
/dev/sdc: open failed: No medium found

 

[webservio]

The error happens in various scenarios, e.g. qmrestore or pct restore command(s).

maybe this helps explaining it:
https://forum.proxmox.com/threads/a-warning-dev-sde-no-medium-found-everywhere.57537

else check with lsblk, dmesg what devices /dev/sdb and /dev/sdc are

I hope this helps!

Hello,

after removing a VM with Nextcloud & remove drive from server, I get same issue.
Is there a solution how to remove that ghost drive? (not just adding to a filter as in other post)

root@pve:/etc# pvs /dev/sdb: open failed: No medium found PV VG Fmt Attr PSize PFree /dev/sda3 pve lvm2 a-- <111.29 13.87g

Using lsblk - sdb is not shown.

The folder sdb is always generated after restart (even if deleted)

root@pve:/dev# ls *sd*
sda  sda1  sda2  sda3  sdb

but fdisk cannot open:

fdisk: cannot open /dev/sdb: No medium found

and also following does not work:

root@pve:/dev# vgreduce pve /dev/sdb
  /dev/sdb: open failed: No medium found
  Failed to find device for physical volume "/dev/sdb".

check with the output of `dmesg` what /dev/sdb is supposed to be - that might show us if it's easily possible to get rid of it...
