| tomreyn | heller: hmm, if you don't have /etc/default/grub this suggests that grub is not installed, which suggests your server is booting some other way - which I don't think Ubuntu would do (but a derivative might). I this a dedicated server, or a virtual (private) server, and if so, does it have its own kernel? | 02:41 |
|---|---|---|
| tomreyn | Actually, the system architecture would also matter in terms of how it boots. ARM systems won't boot with grub. | 02:41 |
| sarnold | I think grub is only used on platforms that smell kinda like intel | 02:41 |
| mwhudson | sarnold: arm64 boots with grub too | 02:50 |
| mwhudson | well, sometimes | 02:50 |
| sarnold | mwhudson: lol classic arm | 02:50 |
| mwhudson | servers do | 02:50 |
| sarnold | no two are alike.. | 02:50 |
| sarnold | mwhudson: is that the ones with an efi implementation of some sort? or is that something else? | 02:51 |
| mwhudson | sarnold: yeah i was thinking of servers, those mostly boot efi -> grub | 02:52 |
| mwhudson | you can boot via tianocore on rpi4 i think? | 02:52 |
| mwhudson | well servers or, uh, network cards? https://www.mellanox.com/products/BlueField-SmartNIC-Ethernet | 02:54 |
| tomreyn | so... like intel | 02:54 |
| mwhudson | https://imgflip.com/i/5wap8l | 02:55 |
| mwhudson | well if you define "smells like intel" as "boots via uefi" then well | 02:56 |
| sarnold | I was thinking just amd64 and i386 kinds of things, and hadn't expected any arms of any sort to boot with grub, but it does sound vaguely familiar once you mention it | 02:57 |
| tomreyn | the number of compoentns which are *not* self-aware and make their own decisions is definitely going down. | 02:57 |
| sarnold | mwhudson: lol | 02:57 |
| mwhudson | tomreyn: for sure | 02:58 |
| mwhudson | tomreyn: how many arm cores are in my (intel ;-p) laptop i wonder? | 02:58 |
| mwhudson | sarnold: anyway yes, ppc64el systems boot via prep and s390x systems boot ... differently | 02:59 |
| mwhudson | i'm sure you can somehow boot s390x via tianocore and grub if you're determined enough | 03:00 |
| tomreyn | mwhudson: originally 7, but 3 were added on the supply chain | 03:02 |
| mwhudson | also it looks like risc v servers will be uefi + grub too fwiw | 03:03 |
| mwhudson | tomreyn: heh | 03:03 |
| mwhudson | i bet it's more than 7 | 03:03 |
| tomreyn | maybe we just misunderstood the concept and it's really a whac-an-arm game | 03:05 |
| tomreyn | risc v with uefi, does this mean secure boot? | 03:05 |
| tomreyn | or rather ... mandatorily closed firmware | 03:06 |
| mwhudson | i don't know | 03:06 |
| mwhudson | it's not very obvious who would handle signing and such | 03:07 |
| tomreyn | well, let's hope for the best. | 03:12 |
| mwhudson | https://imgflip.com/i/5war2t | 03:12 |
| tomreyn | microsoft being the best, of course | 03:12 |

| icey | hey jamespage, would you mind looking at the focal branch in https://code.launchpad.net/~chris.macnaughton/ubuntu/+source/ceph/+git/ceph for sponsoring? it's built on many arch's at https://launchpad.net/~chris.macnaughton/+archive/ubuntu/ceph-octopus/+packages | 08:00 |
| heller | soo lets try again. how to check if my network is okay? | 08:28 |
| heller | seems like ipv6 is disabled with the sysctl -w commands | 08:33 |
| heller | but when i reboot, it always comes bask | 08:41 |
| heller | back* | 08:41 |
| heller | ah, had to add the /etc/init.d/procps restart in /etc/rc.local | 08:45 |
| heller | wht is procps? | 08:45 |
| tomreyn | it says on its second line | 09:03 |
| tomreyn | and you'd configure sysctl settings in /etc/sysctl.conf.d/ to make them permanent | 09:04 |
| tomreyn | no need to have / edit /etc/rc.local for this | 09:04 |
| heller | It says nothing about conf.d | 09:11 |
| tomreyn | heller: sorry, it's /etc/sysctl.d/ | 09:32 |
| heller | guide says etc/rc.local? :p | 09:43 |
| heller | guide says "One method to make this option persist is modifying /etc/sysctl.conf" | 09:47 |

| xnox | mwhudson: so s390x cannot do tianocore+grub, but what suse do is this => normal looking zipl + kernel + initrd => which contains grub-emu and then does grub-emu based boot off the hard drives. | 14:00 |
| xnox | which imho is slow and borderline insane. | 14:00 |
| xnox | but it does give the end user / sysadmin the same experience, i.e. update-grub to change kernel cmdline, etc. | 14:01 |
