I have a Dell R210II server running Server 2008 R2 Standard. It runs 4 disks in a Raid 5 array on the Dell Perc S300 controller. One disk is in a predictive failure state, the replacement will arrive Monday.
The server hosts SQL and Microsoft Dynamics GP for our accounting department, I back the databases and system state up daily. I need to perform a bare metal recovery before swapping that drive and am hoping to use Windows Server Backup. The problem is that there is a Dell provided partition named OS, it is a 2 GB system/primary that I imagine contains the boot sector. It is formatted fat32 and server backup balks when asked to perform a backup because of this.
My concern is this: If I try to perform an ntfs conversion on that partition, I'm forced to reboot. I'm wary of rebooting due to the compromised raid array. I'm also a little unsure of how to proceed if I convert that fat 32 OS partition and Windows then will not reboot.
Ideally, I'll be able to perform the bare metal restore to a 2TB usb drive and, if disaster occurs while trying to replace the failing drive, rebuild the array, reinstall the OS and backup from that image.
Would appreciate any tips for a solid plan of attack here.
