Hey guys,
I noticed that my VM with Home Assistant suddenly stopped working the other day. It wasn't apparent to me why - because the VM was running fine and could not see anything suspicious in the logs, that was until I ran VNC remote on it - and it was clearly having some issues with read write operations.
I then proceeded to check the logs on my cache disk - it was flooded.

Here's a snippet from it:

Can anybody make anything out of this? Could the disk be broken?
Any help would be much appreciated!

 

Please post the diagnostics.

Ah, thanks!

Looks more like a connection issue, check/replace cables, both power and SATA.
