I had 9 of 2-3Gb drives from old systems and unused Drobos, and decided to build a large FreeNAS server with RAIDZ3 -- partly to experiment, but also for a large backup server for my family's computers, and storage for an EyeTV DVR and Plex. Since a few of these drives are a bit aged, I'm slowly replacing them with new or larger drives.
On the last two drive replacements, when the new drive is resilvering, FreeNAS' daily email reports a second drive also resilvering. The same one did it on both replacements. I expect this means the second drive is starting to fail and takes a hit during the intensive resilvering process. However, I get zero errors or warnings from that drive during daily use.
Is there another reason this could be resilvering? Perhaps part of the reorganization of data or checksums?
Thanks for your help.
P.S. The motherboard is aging, as well, so that may also be a project soon. However, we have relatively light usage. There are occasional backups. Two of the family occasionally use the FreeNAS for Plex, with little local encoding needed. The biggest user is one that stores a lot of their games here, and plays them from their LAN PC. He built a sweet gaming PC, but skimped on the HD size. He's inherited the previous 2GB I replaced, so that should change soon.
