SoftRAID reported that one of the drives in my ThunderBay 4 was likely to fail, so I replaced it with another similar drive (the same exact model was no longer available). However, since replacing the drive, my RAID has been in rebuilding status for almost two weeks. At the time of this post, the offset is 2,443,040,489,472 and the estimated time remaining is around 14 hours. However, the time remaining tracker will frequently go to hash marks and then restart the estimate.
I've mounted the drive and left it unmounted but with my machine running overnight. Neither action seems to help. What gives?
The volume must be mounted to rebuild. Please attach a SoftRAID tech support file, with the volume mounted and I can look.
(i assume you are not getting any warnings from macOS that the volume is damaged and mounted read only?)
Here's the tech support file. Still says it's rebuilding.
Set volume optimization to "workstation" for faster rebuilding. If hte volume is healthy, it should start incrementing the IO counters immediately.
is MacOS complaining that the volume is damaged and mounted read only? If so, it needs the directory to be repaired.
Ok, I've swapped the optimization to workstation and it does appear to be rebuilding more quickly. Once it's rebuilt if I change it to video is it going to have to rebuild all over again?
MacOS is not throwing any errors at all. It's just been taking far too long to rebuild with the new replacement drive I put in.
I would leave optimization where it is, only change it back fi you are rebuilding and need to use the computer for intensive work, where rebuilds are paused when you are using the computer.
