The title is correct, I have lost all of my data*. Let’s start with what happened, Oregon has been going through unpredictable weather, lately, it has been hot upwards of 90°F (32°C) which to someone isn’t bad, but our A/C died. So it has been hot inside and outside, This causes problems with computer hardware, especially my NAS. With the CPU hitting 150°F (65°C) it was getting uncomfortably hot for me, during this time 2drives died. One was in the boot-pool, and one in my main drive pool, if you have seen my post you may think “Well you are running RaidZ-1, so just replace the drive” The issue is that one of my Metadata Special Devices died, of which I had one… But to my credit, I was unaware that losing this drive would effectively brick my array. When you add it in the Truenas(Scale) dashboard it does not tell you that the loss of the vDEV would cause catastrophic data loss. So when I gracefully shut down the server to let my room cool down, I was unaware that when I powered the system back on my ZFS pool would not be able to be mounted.
Now onto the aftermath.
When the system was powered back on, it booted like normal and didn’t notice any drives missing. Now post boot I noticed that my SMB share was still showing as offline, so I logged into my dashboard to see what was up and noticed that pool Share was marked as unavailable. I immediately checked the SAS cables, to see if something came loose, So I exported the pool and went to reimport it, and was given this.
Now what. I either just kiss my data goodbye or recover it. I have 2 options, that range from expensive to exorbitant. I started by reaching out to Drive Savers, I explained the issue and was given a quote for between $3,900 and $16,400 for a successful recovery. I said audibly on the phone “Jesus fucking Christ.” So a professional service is off the table. Now I have to look for something I can do myself, after sniffing around for a cheaper solution I found Klennet ZFS Recovery, Still being expensive it is more in my price range at $400. So I will be trying this before looking into any more offsite options.
