Hello Forum -

I have been running my first FreeNAS box on 9.2.1.5 (bare metal) for just under 3 months now. It has a single pool with 7 2TB Seagate SATA drives configured as RAIDZ3, plus SSDs for ZIL and L2ARC and 64GB of ECC. It is used in a small office environment for CIFS file shares and light ESXi/NFS duty. Performance and stability have been very good overall. I have deployed a second, identical box within the environment and do nightly snapshot replication to this DR box, where CrashPlan runs in a jail doing offsite backup. All of this was pretty easy to set up using the excellent documentation - thank you FreeNAS!

I was away on vacation last week and (of course) while I was away a drive failed, and I was notified via email that the pool was in a degraded state (thank you FreeNAS!). Nobody complained about any performance issues and no other problems were encountered until I returned.

It was difficult for me to see exactly which physical drive failed so I ran a scrub to see which disk light was not being lit. That allowed me to quickly figure out which drive to replace. I then followed the procedure in the online manual for drive replacement (which went perfectly, thank you FreeNAS!) and ~ 10 hours later I was fully resilvered and back to a non-degraded state.

I see that there are a lot of problem reports in this forum so I just wanted to post a success story and give thanks for the excellent work that has been done by the FreeNAS team, both on the code and the documentation.

Thank you FreeNAS!
