I built a home NAS two years ago, that was the first COVID summer and I finally had the time. It’s running Proxmox, which is running TrueNAS (then Core, now Scale) as a VM. An HBA card is passed directly to the TrueNAS VM. The HBA card is a Dell PERC H310, but I’ve crossflashed it so that now it shows up as an LSI SAS2008 PCI-Express Fusion-MPT SAS-2. The system originally had five ST4000VN008 disks (4 TB) in a RAIDZ2.<\/p>\n\n\n\n
Pretty much from the beginning I noticed the system was spewing out storage related error messages when booting up. ZFS also noticed, but after the TrueNAS VM was completely up, there were no more errors and I quite rarely rebooted or shut down the system, so I wasn’t too worried. The few read errors I got each boot I cleared with Last summer we had very cheap electricity here in Finland, something like 1-3 c\/kWh plus transfer and taxes. Well, this summer it can be even 60 c\/kWh during the worst times. I started shutting down my NAS when I knew we would not need it for a while. This made the disk issues worse.<\/p>\n\n\n\n I know the high electricity prices are partly due to Russia’s attack in Ukraine and the sanctions against Russia. I completely support Ukraine, they are fighting for the freedom of all of the Eastern EU border states. Please donate to support Ukraine.<\/a><\/em><\/p>\n\n\n\n TrueNAS keeps only one day of systemd journal data (why?) so I’ve already lost the actual error messages. By going through my Google search history I was able to find some of the errors I got. They were like this:<\/p>\n\n\n\n Because there’s quite a lot of discussion on the web about Ironwolf firmware issues, issues with NCQ etc. I hoped this was something that could be fixed with software. I tried passing many kernel options found by googling to the TrueNAS Scale kernel. I came up with None of these options helped. Eventually the whole disk just disappeared. At this point it was clear to me that the issue was not a kernel bug, a disk firmware bug, an HBA firmware bug or anything like that. The disk had been faulty already on arrival.<\/p>\n\n\n\n I noticed Seagate has come up with new versions of the Ironwolfs. The 4 TB version is now ST4000VN006 with 256 MB of cache instead of 64 MB. The new version is also physically thinner and might run cooler. I ordered one of those. Unfortunately the firmware version is still SC60.<\/p>\n\n\n\n I replaced the faulty disk with the new one, ZFS resilvered the pool in about 8 hours and all is good again. I guess the moral of the story is that it seems like a disk could be defective, it probably is and you should start by replacing it.<\/p>\n","protected":false},"excerpt":{"rendered":" I built a home NAS two years ago, that was the first COVID summer and I finally had the time.
