I have a RAID 5, consisting of 4 disks.
1 disk is gone now, and the drive is registered as "failed"
I expected to be able to rebuild to new disk, as this is the point of a RAID 5.
I do not have that option??
I can set the new disk as spare, but rebuilding does not begin because the RAID is "failed".
There is also the "ghost" of the old disk, listed as missing, and I cannot remove it.
So, how do I change RAID status to "degraded"?
Otherwise, or most importantly, how do I force a rebuild to the new disk?
And how do I get rid of the "ghost" disk.
I have used both Intels RST (in a few different versions), and the ROM option without much luck.
When a disk on any RAID volume shows as Failed, this means that no data and structure are available.
At this stage, to get the drive back and running, you need recreate the RAID array.
