I had a RAID 5 array of four 4TB drives on an Adaptec ASR-51245. I installed an extra four drives and added three of them to the array (with the fourth as a hot spare).
The process of reconfiguring has been running now for some days (37% complete) and the RAID card just started screaming at me saying that the array is "Degraded Reconfiguring", while drive 0 (the 1st one) of the array is reporting "Failed Logical Device Segments". The reorganisation of the array appears to be continuing and I've managed to silence the alarm using Adaptec Storage Manager.
I found the following in syslog:
Oct 16 20:59:43 Charon smartd[935]: Device: /dev/sdb [aacraid_disk_00_00_0] [SCSI], SMART Failure: HARDWARE IMPENDING FAILURE TOO MANY BLOCK REASSIGNS
and /usr/StorMan/RaidEvtA.log says:
16 October 2018 22:52:56 BST WRN 301:A01C-S--L00 Charon.home Logical device is degraded: controller 1, logical device 0 ("Shared").
I suspect that so far the drive is still 100% readable.
I've ordered a replacement drive, but wonder what my best recovery approach is once the reconfiguration completes:
Thanks in advance
David

I've ordered a replacement drive, but wonder what my best recovery approach is once the reconfiguration completes:
Assuming the drive is still only in "warning" state, mark it as failed, remove it and replace with the new drive, and let the card rebuild the array, or
Power down and offline copy the old drive 0 to the new replacement?
Some other approach
Thanks in advance
