January 19, 20224 yr Need help here on best strategy: I’m going to be moving unraid to a r720 and DAS. R720 - will hold the cache drive SC200 - will hold my array drives I have strategy on transferring array drives so I don’t have issues there as it’s plug and play with my hba card. My only concern is the following: R720 required configuring Raid0 and reformat when connecting new drives. Since I will be connecting my cache (ssd) into the r720, I will need to configure as raid0 and format the cache drive. If I move all items off the cache drives before the move, will I have any issues with configuration of array (after configuring raid0 and formatting)? Will the new server recognize serial and just continue to use this as cache drive? Is a better option for create new config (before the move) without the cache drive? My concern with removing the cache drive is that I’ll most likely have to create new parity rebuild, which I wouldn’t want to do!
January 19, 20224 yr In general, disk are recognize by serial no. so moving disk between local or DAS no need config anything, Unraid won't know disk in local or DAS. Success or not depends on what kind of connection and DAS you use, just stop array auto start, then moving disk and check back does all show correctly.
