Happy Sysadmin day to all you hard working people keeping the lights blinking and the packets moving!

Ah. It wasn't a failed migration between #ESX datastores.

Apparently, if you take a #VM snapshot with an ISO connected (stored on another data store), even if you unmount the ISO later on, it marks the other data store as in-use by that VM.

Only way to remove that link is to delete any snapshots of that VM with the ISO connected.

Thanks #VMWare!

Apparently, having ISO files connected to your VM's may cause inconsistencies when migrating them across datastores.

Now I have to migrate them back and forth AGAIN!

Thanks #ESX!

Whitespashe is now running Mastodon 2.9.0rc2! Lets take a look at these new features!

#sysadmin #mastoadmin

Thanks to some google-fu, the #homelab is now running on a distributed virtual switch!

Storage access should be much quicker now, with more resiliency becoming possible as I add new #ESX hosts!

All in all, a pretty happy ending for a #sysadmin Sunday!

So, I've managed to fix our media library randomly losing its mount point.
Autofs to the rescue. With any luck, the mount will go up/down according to need. It'll be a bit more resilient of disconnect/reconnects too!

So, for the last two days, my entire home-labbed infrastructure has been on the fritz.

I have a consumer QNAP providing storage for all my VM's and it's just not fast enough to keep up! I'm reliant on heavy caching on an SSD to offset the worst of the lag.

Also, heat is becoming a real issue, I think it's reset itself a couple of times after reaching it's max.

Luckily, I've got a Dell R710 waiting to become a NAS, I've just gotta fill it with drives!

I am happy to announce that our #funkwhale instance is up! And running! It's currently invite-only whilst we test it out.

Q. Is it stable?
A. Mostly!

Q. Does it stream audio?
A. Almost all of the time!

Q. Does it federate?
A. I believe so!

All I need to do now is sort out the other #sysadmin things, like backups.

So, if you're on a funkwhale instance, please check out https://funk.whitespashe.uk !

Disclaimer: Publicly available libraries coming real heckin' Soon™!

Gonna try setting up a #funkwhale instance.... Wish me luck!

#sysadmin

Aaand with that, whitespashe is running Mastodon 2.8.3! Just waiting for elasticsearch to sync up!

New blog post about #spam #spoofing the 'From' address in emails, and how to make sure your domain doesn't get spoofed.

Why's does #ubuntu use #netplan by default?!?! It makes it almost entirely impossible to have both a vlan AND jumbo frames enabled.

Definitely thinking of changing my service hosts to centos. 🤬
