Hi Gene,
Respectfully, if I were you, I might consider tearing down one machine
and rebuilding the data on it bit by bit.
Questions to answer first:
1. Are all the disks the same size?
2. Are all the disks the same manufacturer?
3. Are they all connected to the same controller if this is an add-in card?
If not an add in card:
4. Are they all connected to the SATA sockets on the motherboard?
motherboard?
4. If to the motherboard, are they the only devices connected to the SATA
sockets there?
5. What is the primary device that has / on it - NVME / SSD / spinning rust?

_How did you set the RAID 10 up?
Would you be willing to scrap the data in /home and start again?
All best, as ever,
Andy
