Okay i'm scratching my head at this. I have a Dell R720 server that has a Raid 1 (2 drives) for the OS and then 4-4 TB drives in RAID 5 that I use for my B2D using Backup Exec 2014. I have approximately 8 TB of usable storage.
Everything works well until the backup drive hits 6.2 TB of used storage (leaving 2 TB UN-used). The drive then goes uninitialized, wiping out my backups.
I've updated RAID drivers, etc. etc. and the event log simply refers to a drive is offline.
Frankly I don't even know where to begin to troubleshoot.
