Had drive in slot 7 fail when the box tried to use the hot spare it was also bad so it went into degraded mode

there are also 2 drives in impending failure

first thing I did was replace the drive in slot 7 let it rebuild then replaced the hot spare drive in slot 11 and the system is optimal now and the hot spare is in standby

The issue is that when I try to do a VM backup using Veeam I am getting CRC errors but the servers seem to be running, must just have some corruption.

I am waiting for more spare drives to replace the 2 impending failure drives

can the corruption be repaired or should I just replace the impending drives one at a time when the new drives arrive?

anything that can be done now?
