I have a problem at the moment with one of our main shared folders.
The network speeds to this drive will suddenly slow right down and occasionally completely stop. The shared folder is an iSCSI drive stored on a SAN connected to one of our servers.
The backend of the SAN does not seem to be a problem and you can connect to the server with the drive attached and see the drive with no speed issues, however at the same time the share is inaccessible from anywhere else on the network. The NIC on the server is not reporting lots of traffic and you can remote onto the server with no issues.
I have detached the iSCSI and reattached it onto another server and have the same issues there. Not really sure what else I can do to troubleshoot this or how I can progress any further so any help would be great!
