So if your initial volume size (last default or initial install) was less than 2.9 TiB, then you would hit the 8 TiB growth limit.. my initial install was 4x2tb in raid5 -> 6tb total. I'm happy with raid but it's been up and running for over 3 years nonstop and Load/unload cycles on disks are over 1.2M or 400% of what WD recommends and warranty ended this month, so time to change them before they fail. I'm thinking about going with 4tb which should give me 12tb, so theoretically I should be able to replace disks and grow volume. I guess it will take me a week+ to replace disks one by one / rebuild raid5 / grow volume. Do you know any side effects or caveats that I should be aware of ? Thanks!

I have 4 old green drives that are in my NV+, which have lots of load cycles also. That's just for backup, so I haven't worried about it.

You should be able to execute this plan, though of course backups are always advisable when manipulating disks. If you do make a full backup, you could do a clean factory install with all 4 new drives in place. It could turn out to be faster than 4 hot-inserts and resyncs.

vandermerwe - wdc's position - at least for a while- was that using wdidle3 would void your warranty. Though I never heard of them enforcing it.
