Communication failure when accessing disks on Proxmox node

[lgjunior]

Good afternoon, when attempting to access the disks on my Proxmox node, an error message appears stating "communication failure (0) or Connection timed out (596)". The goal was to view all the disks of the server in order to link them to the server itself. Despite encountering this error when trying to access the disks through the Proxmox interface, running the "lsblk" command from the shell successfully lists the available disks.

Upon checking the system logs, a potentially related error message is found:

Is the issue with the sdf device causing the timeout error?

Possibly? Run a SMART long test to start with, and I would run fsck on any filesystems hosted on sdf.

Make sure you have backups, and be ready to replace the disk.
