[06:30] in 20.04, am i supposed to start using nftables instead of iptables? i am pretty sure libvirt relies on iptables. [06:31] for context - i would like to switch to nftables. just asking if virtualisation is ready for it. [06:45] disposable2: libvirt still depends on iptables [06:45] disposable2: the last bigger eval I've seen was around libvirt 5.1 (about a1.5y ago) and there nftables didn't support all features needed yet [06:46] but iptables is done using nftables these days (yeah - complexity) so since this v5.1 libvirt can deal with that [06:47] disposable2: thre are a few words about is in https://www.libvirt.org/news.html [06:48] but this particular change was mostly for firewalld+nftables of which the former isn't enabled anyway [06:49] apart from libvirt, is there any other significant software in 20.04 that hasn't made a full transition to nftables? (i know lxd4.0 is fine with nftables) [06:49] cpaelzer: thank you for the detailed answer [06:53] disposable2: reverse-depends --release=focal src:iptables is still rather long, but I'm unsure to what extend those might be iptabels|nftables kind of dependencies without looking further [06:54] disposable2: looking through the list ufw, firewalld and docker.io to name a few [06:56] interestingly systemd also depends on libip4tc2 which is part of iptables as well - not sure what it is used for thou [06:57] cpaelzer: this is weird, firewalld is supposed to be able to use nft since version 0.6.0. but thank you. this reverse-depends is a truly magical command [06:59] i would've normally used aptitude for that [07:02] "aptitude why" can help why hings are on a local system, but I like the above for a global overview [08:48] There was a grub bug introduced in a security update yesterday, or thereabouts [08:49] I looked through the irc logs for #ubuntu-server, #ubuntu-devel and others and didn't see reference to it [08:49] I expect the right people are on to it, but here is a report [08:49] https://askubuntu.com/questions/1263125/how-to-fix-a-grub-boot-error-symbol-grub-calloc-not-found [08:51] It probably affects all ubuntu and ubuntu spins; certainly server, desktop and mint. [11:13] danshearer: that is at https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1889509 [11:13] and yes people are on it [11:13] Launchpad bug 1889509 in grub2 (Ubuntu) "grub boot error : "symbol 'grub_calloc' not found" [Undecided,Confirmed] [11:20] cpaelzer, actually i expected the message to reboot after the grub2 update, good thing i have not rebooted yet. === Wryhder is now known as Lucas_Gray === compdoc_ is now known as compdoc [16:27] xnox: I have a question on your grub MP because I'm not familiar with the install_devices_empty case where we still break [16:27] https://code.launchpad.net/~xnox/grub/+git/grub/+merge/388383 [16:34] rcj: install_devices_empty should never be reached, as it cc_groub_dpkg always sets a value. [16:34] rcj: install_devices_empty means "i chose not have package installed, but not actually install grub anywhere" which is fine non-interactively. [16:34] bah [16:34] rcj: install_devices_empty means "i chose _to_ have package installed, but not actually install grub anywhere" which is fine non-interactively. [16:35] because i want to have grub-install available to "rescue" other drives for example. [16:35] rcj: which ami did you boot on xenial to test this? i will have xenial built with that patch soon, and we can test things. [16:54] xnox: thanks for the explanation for the patch. I booted Xenial in AWS (us-west-2 ami-060d1be0dd4526759 built on 20200611) [16:55] and I booted an m5.large or m5a.large instance so I have an nvme root [16:56] ack === tds7 is now known as tds [18:57] I have been having some rather unfortunate issues with NFS crashing or hanging at the Kernel level, and am not sure how to further debug if: https://paste.ubuntu.com/p/3QXRD7DDNF/ - Would anyone be able to provide further support? [19:01] Well, that was unexpected... [19:01] So just to re-ask... I have been having some rather unfortunate issues with NFS crashing or hanging at the Kernel level, and am not sure how to further debug if: https://paste.ubuntu.com/p/3QXRD7DDNF/ - Would anyone be able to provide further support? [19:02] I just wonder which module is tainted here [19:04] https://www.kernel.org/doc/html/latest/admin-guide/tainted-kernels.html [19:04] the kernel or some module is non-gpl [19:05] Well, I am running ZFS and that is predominantly where the NFS shares are being used. [19:06] So that is likely a cause [19:06] probably [19:06] but that hang isn't from ZFS as far as I can see [19:07] whih kernel/distro is this? [19:07] Ubuntu 20.04, 5.4.0-42-generic [19:10] Hello, I hope this channel can answer my DPDK question. I want to attach a dpdk pdump process to my running dpdk application, however I get the following error: EAL: Cannot initialize tailq: RTE_FIB (full error: https://bpa.st/DKYQ) I'm calling rte_pdump_init() after rte_eal_init() as done in the testpmd app. I get the same error when modifying the [19:10] l2fwd example for pdump. [19:10] I am using a FUSE filesystem shared out via NFS as well, that could be it? But afaik FUSE is a part of the kernel now, and isn't non-standard. [19:11] aloini: oh that feels pretty plausible to me [19:11] that'd be worth testing separately from zfs if you cant [19:11] s/t$// [19:12] I can easily stop sharing the zfs nfs exports. Nothing should be using them, they were mainly backups in case something else wasn't working. [19:12] Problem is that it happens randomly, usually after 24 hours. [19:28] You asked for the full trace RoyK: https://paste.ubuntu.com/p/RY6RDM2gH3/ [19:42] aloini: no idea, but it looks like it's related to unicode or something [19:42] aloini: erm - is this zfs-fuse? [19:45] No [19:45] rclone/mergerfs FUSE === Napsterbater is now known as Guest52776 === Napsterbater_ is now known as Napsterbater [21:23] Hey all! I have an HP ProLiant G7. It's connected to the net via Ethernet Port 1. [21:24] However, I can't connect to this machine (nor from it) until I run this command: [21:24] sudo dhclient -r eno0; sudo dhclient eno0 [21:24] Not sure why the DHCP client isn't loading. but is there any log, or configuration that I should check as to why my connection isn't working after every startup? [21:25] (Not sure that it isn't loading/starting, but that's my best guess based on the solution) [21:35] EmberCrest: you didn't state which ubuntu release you're running, but all the supported ones other than 16.04 have journalctl -b [21:35] on xenial (16.04) you'd look at syslog instead [21:36] where configurations ar likle ystored also depends on your ubuntu release [21:43] tomreyn: xenial was the first lts with system fwiw [21:44] +d [21:56] mwhudson: oh right, just not persistent journal, but journal [21:56] ah yes [21:57] shoudn't matter here, though
