Instructions

I got a copy of this program from VMware through an SR when they helped a customer of mine. It is called vCert. This little program is super simple to use and works pretty great. It does everything and anything to do with Certificates on your vCenters. Unfortunately, VMware has not made this public yet. I wish they would.

Sesutil / LEDmon on TrueNAS SCALE

Enable dev mode to enable apt: install-dev-tools
apt update
apt install ledmon
ledmon locate=/dev/sdaX (replace sdaX with the failed/failing drive)

UPDATE: doesn't seem like it's possible... truenas/sg_ses doesn't see the enclosure at all when the card is in IT mode. :(

install the sg3-utils package

I installed it via the deb file so that I don't have to mess with restricted apt permissions truenas comes with.

To download: wget http://ftp.de.debian.org/debian/pool/main/s/sg3-utils/sg3-utils_1.45-1_amd64.deb

To install: dpkg -i sg3-utils_1.45-1_amd64.deb

This started happening with docker v20.10 on ubuntu 22.04. Specifically I had errors like these pop up when trying to run the rancher/agent (for rancher/server v1.6.30):

time="2021-06-29T09:13:28Z" level=fatal msg="Failed to find container id:\n0::/\n"

Seems to be caused by cgroups v2

To make it work again run: echo 'GRUB_CMDLINE_LINUX=systemd.unified_cgroup_hierarchy=false' > /etc/default/grub.d/cgroup.cfg

FusionIO / Fusion-IO devices on TrueNAS SCALE

WARNING: This is unsupported and has potential to mess your system up. Proceed at your own risk.

Initial instructions were for 22.02.1 but also works for later versions with some additional steps. There's notes for each upgrade I've done at the end of the gist.

Note for v22.02.2:

there's a bug where it doesnt show fusionio disks at all under Storage > Disks. So I had to downgrade to 22.02.1 and it works fine.
