[PVE-User] Critical medium error

[Gilberto Nunes]

Hi list

I get this issue from an external USB hard disk:

CAPACITY(16).


As consequence I get a extremely  slow vm access.

So I detect that this External Driver has some problem. After disconnect
this External Driver, everything is go smoothly...

Is that right??? An external driver could be the cause of this slow access?

Anybody has some experience with this???

Thanks a lot
