Systems & Networking

The FreeBSD ports tree only has the old PgAdmin 3 desktop app available, there is no port for the web based 4.x series. It's very unfortunate that the PgAdmin developers chose to go this route. It seems that no one these days is capable of building an application without falling back to HTML and Javascript. It's just another example of the sad state of the technology ecosystem and developer skills. Anyway, lets install PgAdmin 4 on FreeBSD.

I'm trying to squeeze out a bit more life from some IBM x3650 and x3550 M2's. These systems are quite old, but still pack enough power to run meaningful workloads when the upgrades are maxed out. There is one last upgrade you can do that will allow you to unlock the ability to run VMware ESXi 6.7 on a IBM x3650/x3550 M2.

Your XigmaNAS, NAS4Free, FreeNAS, of in general your NFS server is repeatedly showing a mount access error denied in the logs. The NFS client that's trying to mount an NFS export that does not exist or once existed. The NFS client is a VMWare ESXi host.

The Problem

A VMWare ESXi host is trying to mount an NFS export that you deleted or moved.  You log is spammed with endless mount request denied entries.

This is a slight departure from FreeBSD land, but there is no reason why this can't be applied to FreeBSD as well with some slight modifications. Here we will use Saltstack to automatically partition, format, and mount a volume in Ubuntu Linux 20.04.

This is a quick guide on how to resize your ZFS pool after adding more storage. We won't get too much into the details on how to add more storage to a multi provider ZFS pool or RAID setup (that's a complex subject). This guide will be limited to a single provider (aka 'disk' or volume).
