really... I will need to update my 21.05.2 since the layout is like this

[21.05.2-RELEASE][admin@sg4860.local.lan]/root: zfs list
NAME                 USED  AVAIL  REFER  MOUNTPOINT
zroot                957M  24.3G    96K  /zroot

I had skipped the last update clean install, was waiting for 21.09 which didn't happen so I take it that is why.. Now that 22.01 has been released I will be doing clean install of that most likely today. I have ticket open already for install for my sg4860

I do not believe just upgrade will change the zfs layout - maybe I am wrong?

@johnpoz

See here , has both "your layout" 2.4.x in first post.
And 2.5.2 in 2'nd

I doubt they can change the layout on an update, since they're running from the "same disk".

The upgrade won't change the layout, it would require a reinstall.

At this point the new layout is primarily for disk optimization (different ZFS capabilities enabled/disabled on different datasets) but in the future, who knows.

No plans to deprecate the existing upgrade process as far as I'm aware, but if you have the time and the ability, it's a good time to reinstall+restore.

Yeah that is the plan, just waiting for the install image from support. This for sure has been longer than normal.. But with the release just coming, I take it they are pretty swamped.. I can wait ;)

If i'm on 2.5.2 would an upgrade to 2.6.0 be possible (as in not reinstall) , as i already have the "new layout" ?

I'm a bit confused about the above answer

jimp

There were more changes to the layout in 2.6.0

The layout on 2.6.0 looks like this:

: zfs list
NAME                   USED  AVAIL  REFER  MOUNTPOINT
pfSense               4.14G  24.4G    96K  /pfSense

pfSense/var/db        6.64M  24.4G  6.64M  /var/db
pfSense/var/empty       96K  24.4G    96K  /var/empty
pfSense/var/log       5.16M  24.4G  5.16M  /var/log
pfSense/var/tmp        148K  24.4G   148K  /var/tmp

You might have some of those changes, but not all of them.

I'm on the same boat :) Already opened the ticket and now just waiting... Today is going to be that day you know, install, configure, test and a lot of coffee hehe

My 2.5.2 CE looks the same. So is it safe to upgrade to 2.6.0? Or is a fresh install really required? If I can save the hassle and not cause instability I'd prefer not to...

@mcury This is has been the longest it has ever taken them to get back.. I can only assume they are swamped with bigger issues than asking for the install media ;)

Indeed, its nice to see that Netgate is getting bigger.. If things were better for me, I would be getting a SG-6100.. Maybe later this year or next year, who knows? :)

johnpoz

@mcury Just got my link to download ;) With all that is to be expected on release day.. I am very happy and pleased with a 2.5 hour response to a "request" for something that is by any means at all urgent or any sort of issue.

mcury

@johnpoz Hm nice, I also opened the ticket 2.5 hours ago, at 10:44am LT (GMT -3)
But I'm not in a rush, if I install it now the users here will attack me with their bare hands.. :)

johnpoz

@mcury yeah while don't have any users currently that would complain if internet went down for a few minutes.. Wife is out for the day ;)

I am in the middle of some escalations for real life work, and loosing internet would not be a good thing ;)

But hope to for sure get to this sometime this afternoon. If you get to it first, let us know how it went.. I will post when I have it completed ;)

mcury

I'm on vacations , and I'll be traveling on Friday, one week on the beach.. :) So everything must be ready before I go.. I'll try to do it after 17:00, maybe after 22:00, not sure yet

I'll do it, everything is ready, even the certificates are store in a .txt file.. Wireguard keys and all..
Just waiting for the time window, I can't take the risk of being killed by the users :)

I hear ya brother ;)

johnpoz

@mcury well I pulled the trigger.. Some oddness with packages being reinstalled. Was told they didn't exist in plus.

But guess there is a redmine about it already or was, should of looked before pulling the trigger I guess ;)

https://redmine.pfsense.org/issues/12766

I do believe I got it all sorted out, those packages have been installed, and my previous configs for them were still there.

And have the new zfs layout now.

Total time without internet a few minutes.

@johnpoz Soon its going to be my turn, just got the download link. :)
I'll check now the hash to make sure everything is correct, burn the iso to the pendrive and just wait for the better time to proceed..
I won't restore the config, will configure it from scratch.. This will be my opportunity to clean my aliases and rules, its currently a mess.. Aliases not in use, aliases that the IPs already changed and etc..

Never a bad idea to take the down time as time to clean up..

I wanted to test the recovery process of the config, which worked pretty freaking good if you ask me.. Other than some oddness with a couple of packages, which was no biggy and could of expected that if done my due diligence and looked over any recent redmines reported ;)

If you take that out of the picture went as smooth as you would expect.. Literally a reboot and back up and running.

edit: If I was going to nitpick - the longer than normal time to get a link to the media for install. In the past its been as fast as like 4 minutes or something. But hey make such a request a few minutes after the release announced - I am more than happy with the couple of hours it took.. I would expect they got bombed..

@johnpoz
Are you the first to take a ZFS Snapshot on 2.6.0 , and test "Rollback"
