My current setup is eleven 1TB drives in a RAIDZ3 array, with one hot spare. I am slowly replacing each drive with a 4TB Ironwolf drive to increase my capacity. I didn't realize that my SAS card (an LSI SAS3081E) is old enough that it cannot address >2TB per drive. Luckily, it was new enough that the drives are appearing as 2TB, and not 512 bytes like older cards may.
Once I realized this, I immediately went and bought a SAS9211-8I card on eBay to replace my old card, but I have a question: Once I replace/upgrade firmware on the new card, will Freenas (11.2) immediately recognize the drives as 4TB and utilize all the space?
Right now I'm still putting in the larger drives at a rate of about 1 per day (takes a while to rebuild each time.) The system sees them as 2TB, so presumably once I replace ALL the drives, the pool will expand to have roughly double the capacity of the 1TB drives. When I install the new card, will FreeNAS see all the extra space and expand the pool size again?
