i have a server with 12 disks - 4x2tb, 6x1tb, 2x 60gb ssd (one for boot, one for cache). each disk has a 1tb partition and each partition has been added to a zpool of type raidz1 (one drive for parity). i'm looking at swapping out my core components (mobo, cpu, ram, hdd controllers) without losing any of my data so i want to generate a backup from the server before i make any changes, only i don't have enough space to store everything in one go. i have about 2tb of free space left in the zpool.
my plan, in theory, is to remove a 2tb drive from the zpool and reconstruct its data across all the drives left in the server. then move 2tb of data from the server to the newly reclaimed drive and repeat until the server is empty (remove another 2tb, move another 2tb of data etc).
can i do this?
the reason i want to go this way is because i'm not entirely sure i want to stick with freenas and wouldn't mind playing with a few options on physical hardware before i commit to anything and move the data back to the server. (currently looking at OpenIndiana, Ubuntu+fuse-zfs, windows server + software raid5).
if you guys have any more suggestions, please, let me know!
