 Tom here from Lorne Systems and TrueNAS Core 12.0 update 3 was released on April 13th of 2021 Today is April 16th of 2021 and yes as soon as it came out I loaded our systems here at the office and mine at the house with the latest update You know I don't mind being a little bit of a glutton for punishment or filing bug reports because I don't just complain about things that are broke Because that doesn't seem to get them fixed Good news is I didn't find any major issues at all or even any minor ones yet Or thus far with only three days of running it now. This is one of our systems here at the office It's an older i5 system custom built That's why it says platform generic here and no problems with the update It runs NFS Samba and some jails they all work fine specifically syncing to sync some of the data around our office here Then I have this system here Which is where this video and other videos for the last few days have been being edited and all the data is stored on For the videos for the my youtube channel and no problems at all including the cloud backups that are tied to back plays everything That's gone through several cycles the systems are replicating to each other some data replicates from here to there the other system and Vice versa so both of these have been talking perfectly fine and didn't run into any issues and the one I did at my house same thing now Those use cases include ice cozy and NFS and some Samba shares But do not include any tie-in to active directory I bring it up because I did see a couple comments in the forums about people who when they did the update had some breakage with active directory and their resolution was to Rejoin 80 servers now of note in case you run into some of those type of issues one always check the forums and you know for Those of you that may or that may have already gone ahead and done these updates and see what problems may have occurred But also when you're doing minor releases, it's actually pretty arbitrary just to roll back So I went from you two point one to you three, which means I can actually just click these and Roll back right away by hitting activate and jump backwards a version Relatively easy the only time this doesn't work is if you update let's say from version 11 version 12 And then you do a ZFS upgrade because there was a change in the ZFS version Well, then you can't roll back, but there's no change in the ZFS version going from The you two or you two point one and you two you three so just a note That's on there in case you're doing any of the updates back to what got changed and what got updated this being a mission critical suitable for Critical release level of update what I mean by that is Once we get past you to that means there's been a minimum of six QA cycles gone through as in for those you that We're waiting and holding back to update This is more where people are going to start moving their systems and our mission critical systems because when I say bug fixes I mean a lot of bug fixes and I have time in this video to go over every one of them and it is amazing how much Bugs people can find in these but there's definitely some that were more notable than others a couple of my highlighted right here Where VSS shadow copy doesn't work after an update this apparently broke under Certain circumstances in you two for people that is now fixed and I've done some videos on this topic where basically these snapshots are Presented via Samba as a volume shadow copying it and specifically as an immutable one Which I think is really great, but of course that feature not working is not so great So it's been fixed in you three. So if you had a problem with it before that has now been resolved Plex jail responding to DHCP. That's a weird one I did not see this problem at all out in the field But I did find it kind of interesting because I can't imagine the circumstances by which a Plex server is what's responding on your network to DHCP because it's not supposed to and which is clearly why it had to be fixed So I thought that wasn't just you know kind of caught my eye and I think when I did my video on lag I'd seen someone mention this I did not experience this specifically because the network interfaces I'm using are not the e 100s But this is a potential scenario where you'll have a kernel panic if they're Are lags set up with these particular network interfaces and there's actually a lot more little bug fixes like this One of them turned out to be a duplicate that I submitted was in the way It was handling a nested dataset encryption the UI didn't accept the Json file So I'd actually submitted that and that's actually been fixed in here Although that it was part of a duplicate bug related to a UI implementation the workaround for that It wasn't major it was pasting in the key as opposed to using the Json file It will let you just drop the keys in and it would still unlock But just wouldn't unlock with a Json file but there's a lot of little nuance and things like that that have to be fixed and They really did a lot of it in here including a few new features as you can see right here a few improvements to the way things are Handled inside and one more thing of note is like known issues There's not much under known issues But this one comes up a lot other than people ask me and it's not as much to me a known issue as they Don't do that issue it is a lot of there seems to be a lot of people that upset that you can't just use root for your Samba shares anymore That's been a change that happened a little while ago. Not just for this version But oh when they switched to 12 and people seem to be upset by that They don't like creating under a user and setting up the permissions on there But I know roots convenient, but it's not necessarily the right way to do that That's one of the reasons that was disabled and persistent l2 arc is disabled by default They have a methodology which you can turn it on so they see the underlying issues have been fixed But the setting continues to be disabled by default for performance So if you are wondering what happened and you want that Turned back on for persistence with the l2 arc that option is in there and that CLI doesn't generate carp password on HA systems there's a lot of little HA nuances and this is important because this is specifically for some of the true Nass hardware that has HA and now they're probably going to recommend a lot more people Go ahead and switch if you're using one of those HA chassis To this version they did a lot of work There's a lot of little notes in there about different scenarios that had to be fixed Now someone may have already left this in the comments But this question does come up all the time is Tom Why aren't you talking about true Nass scale? This anytime I mentioned true Nass and the reason why is because it's alpha still So there are some release dates scheduled release dates here in 2021 We have an updated alpha release on 420 and then we have a beta scheduled For 615 of 2021. So yes, it's coming. It's not here yet. It is on its way I'm as excited as many other people are which if you're not familiar at all with true Nass scale I have a video on it, but essentially it's the re-implementation of true Nass on a Debian base Linux system So we're excited when that gets here Patiently waiting like everyone else that'll get here when the bugs are squashed and of course when you switch to it It's going to initial release have Well, people like me testing it for sure But I don't know that I would throw it on a production system Because it's right now an alpha last time I tried it. There was a lot of functionality broke I might try it when it gets to this next level of alpha But more than likely I won't really switch any system and I'll probably just switch my video editing system to it Once it at least hits beta. So it it is in there really cycle I don't talk about a lot because there's not as much to talk about but if you'd like to test it and contribute to the Repairing and finding and squashing of bugs in it. Go ahead. It's absolutely available for download But it's not quite ready to be used yet. It's the way I would say after my own testing with it It's it's it's still rough around the edges. It's been a few months since I tested it But it was definitely a little rough around the edges I will leave a link to all this on here so you can read the release notes yourself and see if there's some bug issues that you have in there Please note the active direction just in case you have any active directory problems You may have to rejoin it. So anything I really seen in the forums on that But always, you know, keep an eye on the backups. Make sure you have everything backed up Make sure you have your zfs keys and encryption backup if you're using encryption And remember rate is not a backup rate is resiliency. So back that NAS up before you Start all this whole fun project of upgrading, but nonetheless upgraded systems. It's went well for me I'm hoping it goes well for you. All right.
