Server status stuck on indexing xmltv guide data

Server status is stuck on "indexing xmltv guide data". Clients can connect but can't watch anything. cant watch from dvr server web, "Tuner unreachable" from android client, 500 internal server error from ios client. Gathering diagnostics wheel just keeps spinning. Rebooted server OS and generated diags:

1bf5cf83-1584-413e-ba52-ff2cdbe11005

Something is wrong with your F: drive

write F:\DVR\Streaming\channels-cache-3340374433\1325538-49310f6031a733a9009e6a7c3def4fa039f37d919ea1b4a586e0fc9461ab53dd: The parameter is incorrect.

Thanks. Reboot has everything back to normal I’ll run a disk diag to see if it shows anything.
