I would like to replace and existing drive with a larger unit but also change the drive from Reiser to XFS. I have moved all the data from the existing drive to another location My question is can I 1. stop the array 2. replace the drive with the new one 3. set file system of the drive to XFS 4. restart the array 5. format unmountable drive and have the array work without requiring a parity rebuild or will I have to skip step 2 (keeping the original drive in place) continue with 3-5 6. stop the array 7. replace the drive 8. Assign the new drive 8. restart the array to do a parity rebuild.

Done when drive was unattached from the array list. In any event I am back up and running, thanks to yourself and itimpi. Had to do a rebuild. Lost the data on the one drive, but thankfully it was not much and I had a backup of most of it. The rebuild is currently about 75% through but all appears to be well so far. Thanks again for the assistance. Ill chaulk it down to a learning experience.

Don't think so, but not impossible.

Upon further review looks like I screwed up and the emulated drive is actually showing up as empty, and I have already formatted the actual physical drive so it looks like that data is lost. Not a real issue in this case, because the drive did not have very much data on it to begin with. Lesson learned. What is the best way to move forward with getting the array back in order without loosing the data on the other drives. Currently I have stopped the emulated array to be on the safe side.

Thanks. Will review link

The *emulated* drive is functioning and the array starts ok in "Array unprotected" mode. Where i run in to problems is trying to add back that actual physical drive so that I can rebuild the array back to it.

Yesterday a drive mysteriously dropped from my 21 disk array and the array is now running in emulation mode. I brought the array down. Did a smart test extended on the drive which reported no errors. Did a "destructive" through test on the drive by writing/reading/verifiying the entire drive and no errors were found. Tried to add the drive back to the array to do a rebuild, but unraid refuses to add the drive back. I can add it to the slot, but it always reports an unmountable drive error. Any suggestions?
