Can't Add Drive to Repair RAID
I replaced a disk that was failing in a RAID. Per SoftRAID instructions, I replaced the disk, initialized it. Then I right-clicked on the RAID volume but "Add Disk..." option is greyed out.
How do I add the new disk to the RAID so it can be rebuilt?
I'm using a Thunderbay 4 with Mac OS 10.13
Aha! The SoftRAID Lite XT quick start guide said nothing about the process of removing the damaged disk - it just said "Look at the front of the device and remove the disk with the blinking light." I actually looked for further instructions but didn't find any.
So, I just took out the failing disk, while the volume was mounted, and put in the new disk. I haven't saved anything since removing the failing disk. Should I put it back in and go through the procedure outlined in the video? If not, what should I do at this point. I initialized the new disk, but I can't add it to the volume (I also disabled protection).
You can do what you did, as long as you used SoftRAID to initialize the disk.
I assume your volume is still mounted. If you have a disk of the correct size (or larger), then when you select the volume, the option in the volumes menu to "add disk" should be available.
I did use SoftRAID to initialize the disk, and yes, it is still mounted, and it's 2TB, same size as the disk it replaced. But as I mentioned at the outset, "Add disk" is grayed out.
Should I unmount and remount? Restart computer?
send a tech support file to support at softraid. We can take a look from there. This should be straightforward.
This is a RAID 0 volume with no redundancy. SO you cannot rebuild it.
Do you still have the failing disk?
You can put it back in, backup, then create a new volume. RAID 0 has no protection against disk failure.
Aha! That's OK, as I have a 2nd full backup. Which is why I made it RAID 0 in the first place. But I forgot about that.
Thanks very much.
