I am currently running a TrueNAS server (v12.0-U8.1) with a single storage pool (see full hardware list at the bottom). I am not completely new to TrueNAS, but inexperienced enough in this area to have the following questions.
This RAIDZ2 pool consists of 6 identical WD Red WD40EFRX 4TB drives which have been in service since 2013 (I know, I have more than got my money's worth from these drives). I want to replace these 4TB drives with 10 or 12TB drives, and this thought led me to question the procedure of changing, adding, and removing drives from this pool. Specifically:
1. If I replace all smaller drives successively with bigger ones? Will the overall storage size increase once the last smaller drive is replaced? I found this reference in the FreeNAS v11.3-U5 user guide, which seems to indicate this true (see link below),
https://www.ixsystems.com/documentation/freenas/11.3-U5/storage.html#replacing-disks-to-grow-a-pool
but I have not found anything in the TrueNAS v120-U8.1 documentation that addresses this topic (see link below)
https://www.truenas.com/docs/core/coretutorials/storage/disks/diskreplace/
So I am reaching out to the more knowledgeable among you, to see if this process of replacing disks to grow a pool is still supported.
Thanks in advance!
