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

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.

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.

There is no need ibthink. I did all 12 of my cluster at home plus all the work proxmox with no issues

[–] ipkpjersi@lemmy.ml 1 points 1 month ago (1 children)

It might be safer to wait, one of my IRL friends ran into an issue, and I saw some others post about it on the Proxmox forums: TASK ERROR: activating LV 'pve/data' failed: Check of pool pve/data failed (status:64). Manual repair required!

I think I didn't run into that error because I flattened my LVM kinda, but if I hadn't customized my setup maybe I would have run into that too.

[–] ssdfsdf3488sd@lemmy.world 2 points 1 month ago (1 children)

Its in the release upgrade notes. There isvone command to run if you are doing lvm. All my stuff is zfs or ceph so i never ran into it

[–] ipkpjersi@lemmy.ml 1 points 1 month ago* (last edited 1 month ago) (2 children)

I took a look but I'm not seeing any command for LVM mentioned anywhere?

[–] ssdfsdf3488sd@lemmy.world 1 points 1 month ago

Sorry it might be from running pve8to9 program to verify system readiness.

[–] ssdfsdf3488sd@lemmy.world 1 points 1 month ago (1 children)

Actually no. 4.5.2 in upgrade instructions talks about lvm adjuatments needed

[–] ipkpjersi@lemmy.ml 1 points 1 month ago* (last edited 1 month ago)

and the pve8to9 checklist script suggests to run this migration script if necessary

Ah, okay that makes more sense.

This is going to affect many more people who didn't read it, then.

Although, that seems to only affect guests and not hosts?

The host machine becomes unbootable IIRC, so I think it's something else?
