Not quite true, drives in a RAID have the same UUID. |
| 6 |
Here's my raid5 for an xxample: |
| 7 |
|
| 8 |
# blkid | grep mdraid |
| 9 |
/dev/sdb1: UUID="bf59d132-8b98-7d9c-c526-af1cfb835fa3" TYPE="mdraid" |
| 10 |
/dev/sdc1: UUID="bf59d132-8b98-7d9c-c526-af1cfb835fa3" TYPE="mdraid" |
| 11 |
/dev/sdd1: UUID="bf59d132-8b98-7d9c-c526-af1cfb835fa3" TYPE="mdraid" |
| 12 |

So you would need to reset the UUID before reusing a drive from an array. |

Have fun, |
