OK, I could bring it back online using:
bioctl -C force -v -c 5 -l sd1a,sd2a,sd3a softraid0
I wouldn't have expected it to be the -c flag, because that says a "new"
raid and I'm trying to enable a previously active raid.
Anyway, the above command works. And I have no data loss.
Then I had a single disk that was marked bad, which I put online again
like so:
If sd1a failed, like so:
```
softraid0 1 Degraded 4000797294592 sd6 RAID5
0 Offline 0 1:0.0 noencl <sd1a>
'unknown serial'
1 Online 2000398663680 1:1.0 noencl <sd2a>
'unknown serial'
2 Online 2000398663680 1:2.0 noencl <sd3a>
'unknown serial'
```
You can add it back to the RAID like so: `bioctl -C force -R /dev/sd1a sd6`
```
