Hi,
I have been using a raidz2 pool with 10 x 2TB disks for a few years. This week I had a double disk failure and rather than risking resilver of two disks, I'm going to rebuild the pool and upgrade along the way, as I have been in need of more storage for a year or more.
I currently have 5x 2TB and 5x 3TB disks and I'm trying to figure out my best configuration going forward. The most I can afford to spend is for another 5x 3TB.
I can't afford to make all raid1 mirror vdev scored the capacity I need with 50% efficiency, so I will stick with raidz2.
10x 3TB raidz2 = 24TB
Is that a really bad idea? Data is mostly photos and other documents that need to be accessible, but are mostly idle.
Thanks for any input
