I have a Mercury Quad Pro with 4 8GB hard disks. One was marked as failed. I replaced it and now the Quad Pro won't mount so it can rebuild. Any thoughts on what I need to do? I'm running a Mac Studio with latest OS. Softraid 7.6
Attach a SoftRAID tech support file. I see two disks that have a problem, the other has IO errors.
Did this volume mount before you replaced the disk?
if so, what if you remove the disk you added?
@softraid-support Yes, the volume mounted before I replaced the disk. I will remove it today and see what happens.
I removed the replacement drive and the volume doesn't mount still. I have no problem redoing the whole thing (equivalent to reformatting a single drive) if you can point me to how to do it.
That is easy then at this point.
I expect this to be the easiest way:
Insert the drive.
When it has spun it, use SoftRAID to "erase" the volume.
I expect that will clear the out of sync message, also, so you do not need to delete/create a new volume/restore.
Let me know.
So I replaced the drive and now this is what I see. It appears the bottom drive needs to be replaced and the new one "yellow", I assume, is rebuilding. Is that correct? A rebuild can take a while as I understand it. Is there anything else I should do now?
Now you need to "erase" the volume. (delete your data). SoftRAID does not rebuild volumes that cannot mount, it prevents data issues when the directory is damaged.
You will also need to clear the IO counters (errors) on the one drive. then you should see a healthy volume.
