ctviggen Posted January 16, 2022 Share Posted January 16, 2022 I just brought up a new server, with four 8 TB drives and 1 256GB SSD meant for cache. This is to replace my aging (as in really old) unraid server. I need to copy >10TB from the old server to the new server. At end of copying, I would like: one 8TB parity drive; two 8TB data drives; one 8TB "hot spare"; 256 GB SSD cache. Questions: - Cache: Looking at the page for Main/Array devices, there is no cache option. Did the cache go away? - Rename server: How do I rename the server? (Did this on my current server, but it's been 10+ years since I've done it.) - How do I copy >10TB of files from my old server to my new server? If there is still a cache drive, should I make the fourth 8TB drive be a cache drive temporarily (will be a hot spare) to allow a lot of a copying to happen before the cache is written to the array? Thank you. Quote Link to comment

Did the cache go away? No. With 6.9.0 you can have multiple pools (with user specified names), and any of them can be set to cache a share. 2 minutes ago, ctviggen said: Rename server: How do I rename the server?

ctviggen Posted January 16, 2022 Author Share Posted January 16, 2022 Oops...Answered part of the cache. Now it's called a "pool" instead of a cache. Learned that here: Getting Started Still have the question about whether to use the 4th 8TB as a cache/pool when copying files. Quote Link to comment
ctviggen Posted January 16, 2022 Author Share Posted January 16, 2022 Does marking this as "solved" mean all of this is solved? Or only part of it? @itimpi solved two parts of my issue, but I still have questions as to how to copy files and also whether to rename my 4th 8TB drive (meant for a hot spare) as a temporary cache while copying.

trurl Posted January 16, 2022 Share Posted January 16, 2022 When doing an initial data load, don't cache. If you want it to go faster, don't assign parity and build parity after. Quote Link to comment
