Hi,
I'm looking to replace my 2 old 1.5TB drives (recently found out they're 6 years old and I simply don't trust them
). Currently they are in a RAIDZ1 array with two other 2TB disks which are a couple of years old each.
Do I:
Replace one with a new disk, wait for the array to rebuild, then do the other. This means 2 rebuilds of a 3.9TiB array which is 75% full.
Or:
Back everything up to my 4TB external and build a brand new array on the 4 2TB disks? This means 0 rebuilds, but 3.9TiB of writes back to the array once created.
I'm thinking option 2 as it's going to put less stress on my existing 2TB drives... I wouldn't really want to put them through 2 rebuilds in the space of a few hours, or would it be OK?
Thanks
