The new mobile interface is lit πŸ”₯. Finally usable

[–] billygoat@catata.fish 13 points 1 month ago (2 children)

Fuck, I just left for a month away and I hate to do major upgrades when remote.

[–] ikidd@lemmy.world 36 points 1 month ago (1 children)

Probably for the best. Upgrades on the first release haven't had a stellar record

[–] Moonrise2473@feddit.it 4 points 1 month ago (1 children)

Exactly, for example I missed the note that updating truenas to the latest version disables and hides all the virtual machines (theoretically they can get migrated to the new engine but it gave me some weird error. Luckily truenas can be downgraded easily.)

Now, 3 months after the First release of the update, those virtual machines aren't disabled and hidden anymore

[–] SidewaysHighways@lemmy.world 1 points 1 month ago (1 children)

core or scale? are they getting rid of core??

[–] Moonrise2473@feddit.it 5 points 1 month ago (1 children)

scale, they got rid of the kvm emulator in the last release and i was devastated to see all my VM gone. The "migration" consists in you migrate the disk image to the new directory, then you make a new VM... IF you knew that BEFORE the update and took note of all the settings because the old VM menu is gone!

but also it's clear than core is on life support

[–] SidewaysHighways@lemmy.world 1 points 1 month ago (1 children)

poop.

well my truenas is a vm on proxmox, i assume I'll figure something out when it is time lol

[–] Zanathos@lemmy.world 2 points 1 month ago

As of the last update released on August 1st, the "old" VMs are now visible again. The latest Electric Eel chain also merged all Core features into Scale, so the jump should not be as drastic any longer. I've always lived on Scale, but I assume you could try backing up your config and spinning up a new Scale VM and restoring the backup to it. No matter how you dice it though, it will be spicy!

[–] lka1988@sh.itjust.works 2 points 1 month ago

Stick with 8 then, until we know it's stable.

[–] littleomid@feddit.org 37 points 1 month ago (1 children)

For beginners here: do not run apt upgrade!! Read the documentation on how to upgrade properly.

[–] beerclue@lemmy.world 24 points 1 month ago* (last edited 1 month ago) (1 children)

It's always good to read the docs, but I often skip them myself :)

They have this nifty tool called pve8to9 that you could run before upgrading, to check if everything is healthy.

I have a 3 node cluster, so I usually migrate my VMs to a different node and do my maintenance then, with minimal risks.

[–] drkt@scribe.disroot.org 13 points 1 month ago

pve8to9 --full

[–] wreckedcarzz@lemmy.world 20 points 1 month ago* (last edited 1 month ago) (3 children)

Yay, it only took 2 hours and the help of an llm since the upgrade corrupted my lvm metadata! Little bit of post cleanup and verifying everything works. Now I can go to sleep (it's 5am).

Wasn't that bad, but not exactly relaxing. And when my VMs threw a useless error ('can't start need manual fix') I might have slightly panicked...

[–] Appoxo@lemmy.dbzer0.com 7 points 1 month ago

Not something that sounds production ready lol

[–] potpotato@lemmy.world 6 points 1 month ago (1 children)

Started a system upgrade at 3am…you ok?

[–] wreckedcarzz@lemmy.world 2 points 1 month ago

I'm always up late (it's 5:19a), though a good bit more than usual lately. But I did the upgrade because I was anxious, had nothing to do, and there were no users utilizing the machine.

[–] nevetsg@aussie.zone 4 points 1 month ago (1 children)

Thanks for posting this and reminding me to never go back to Proxmox. My Proxmox server killed itself and all VM's twice before I moved onto HyperV.

[–] wreckedcarzz@lemmy.world 2 points 1 month ago* (last edited 1 month ago)

Oof. I have my VMs getting backed up to another machine so theoretically (untested) I should be able to recover with less than a day of data loss (very minimal for this box). The annoying part would be getting it hooked up to a monitor and keyboard, since it's under an end-table in the living room.

This is the first issue in like... 15 months? Hopefully it stays rather uneventful.

ZFS now supports adding new devices to existing RAIDZ pools with minimal downtime.

Yes!!

Not sure I want to check how far behind I am. How rough are these upgrades? I’ve got most things under Terraform and Ansible but am still procrastinating under the fear of losing a weekend regiggling things.

[–] phanto@lemmy.ca 13 points 1 month ago

I just did three nodes this evening from 8.4.1 to 9, no issues other than a bit of farting around with my sources.list files.

Not noticing anything significant, but I haven't tried the mobile interface yet.

I'd also like to know.

I built a new machine seceral months back with PVE and got the hang of it but it's been "set it and forget it" since then due to everything running smoothly. Now I don't remember half the things I learned and don't want to get in over my head running into issues during a major upgrade. I definitely do want the ability to expand my ZFS pool so I will need to bite the bullet eventually.

[–] SheeEttin@lemmy.zip 5 points 1 month ago

I just did one of my two nodes. Easy upgrade, looks good so far.

[–] possiblylinux127@lemmy.zip 5 points 1 month ago

It will vary but for me it was smooth

[–] sandwichsaregood@lemmy.world 4 points 1 month ago

Previous 3 major release upgrades I've done were smooth, ymmv

I am telling myself that updating remotely is not a good idea

[–] beerclue@lemmy.world 10 points 1 month ago (1 children)

My "servers" are headless, in the basement, so even if I'm home, it's still remote :D

[–] HiTekRedNek@lemmy.world 7 points 1 month ago (1 children)

IPMI + BMC are wonderful things.

I tell myself that every time, but I mean, I still end up doing it every time anyway lmao

edit: Just did it, it went well.

[–] bigkahuna1986@lemmy.ml 2 points 1 month ago (7 children)

My work computer is Debian and I'm so looking forward to the upgrade. Just gotta contain myself for a free weeks until a 0.1 type update is released.

As a person who just installed proxmox for the first time a couple of weeks ago, does this allow me to fix some of my mistakes and convert VMs to LXCs?

[–] CmdrShepard49@sh.itjust.works 8 points 1 month ago (1 children)

You could just start over if you dont have much invested into your current setup.

[–] TheUnicornOfPerfidy@feddit.uk 1 points 1 month ago (1 children)

I'm in too deep. I'm trying this script. Fingers crossed

[–] JPAKx4@lemmy.blahaj.zone 1 points 1 month ago

Depending on the services, you should be able to make a backup and restore without needing to delete the real version until you're sure everything is working

[–] SidewaysHighways@lemmy.world 6 points 1 month ago

i don't think so

[–] JPAKx4@lemmy.blahaj.zone 4 points 1 month ago

As someone who also started proxmox fairly recently, I found that the community has these really cool scripts that you can use to get started. Obviously you're running bash scripts on your main node for some, so there are risks involved with that but in my experience it's been great.

[–] coffeetastesbadlikecoffee@sh.itjust.works 5 points 1 month ago (1 children)

This is awesome, I am going to imediatly get a test cluster set up when I get to work. Snapshots with FC support was the only major thing (appart from Veeam support) holding us back from switching to Proxmox. The HA improvements also sound nice!

Anyone got screenshots of the new mobile UI?

Keep on telling yourself that, but most of us aren’t on physical console anyways

[–] mio@lemmy.mio19.uk 3 points 1 month ago

My duplicate comments were caused by my slow home server. I really should upgrade my hardware

[–] BlueEther@no.lastname.nz 2 points 1 month ago

A job for the weekend I guess. just done all the prerequisites and only have a warning for dkms
