It is a drive timing out making the slowdowns. I am looking up the port and serial to confirm I have the right drive and going to unplug it for temporary so this slowness stops.
There will be a Maintenance between 7PM and 8PM Sunday night Central Daylight Time GMT -5, for about a 15-20 minute possible outage while we repair/swap this HD and start the rebuild.
All is good, RAID is rebuilding and server still running well, like nothing even happening, which is the way it is supposed to be done.
End of Maintenance.
