@Cmjohnson I am setting this to high priority because there is one failed disk and another one with smart errors (on a different SPAN).
Let's replace only the failed one.
This is m1 master, so let's do this as soon as possible.

The failed disk is #0 - that is the one we need to replace only so far:

root@db1063:~# megacli -PDList -aall | egrep -i "Slot|Firmw"
Slot Number: 0
Firmware state: Failed
Device Firmware Level: ES66
root@db1063:~# megacli -PDList -aall | egrep -i "Slot|Firmw"
Slot Number: 0
Firmware state: Rebuild
Device Firmware Level: 0008

awesome, thanks!

The sync finished, thank you @Cmjohnson
