| aberrant | hi all | 01:35 |
|---|---|---|
| sarnold | wb | 01:36 |
| aberrant | thanks. | 01:38 |
| aberrant | Does `make bindeb-pkg` make the modules? I don't have any .deb that has the word "modules" in it. | 01:38 |
| connor_k | Sorry I’m not at my computer right now to confirm but I think maybe the bindeb-pkg target might just roll them all up into the *images*.deb | 01:40 |
| connor_k | If you run “dpkg -x | grep nvme” the modules might be listed | 01:40 |
| aberrant | ok, thanks. let me check | 01:40 |
| aberrant | sorry for being so high-maintenance | 01:41 |
| connor_k | Wanting to learn something new is hardly high maintenance :-) if anyone tells you that then they’re wrong | 01:41 |
| connor_k | Er sorry “dpkg -x *image*.deb | grep nvme” | 01:42 |
| sarnold | I don't see anything else in the make help output that looks like it'd generate modules debs | 01:42 |
| aberrant | seth@hydrogen:~/kernel$ dpkg -c linux-image-5.3.10+_5.3.10+-1_amd64.deb | grep -i nvme | 01:42 |
| aberrant | drwxr-xr-x root/root 0 2019-12-16 15:39 ./lib/modules/5.3.10+/kernel/drivers/nvme/ | 01:42 |
| aberrant | drwxr-xr-x root/root 0 2019-12-16 15:39 ./lib/modules/5.3.10+/kernel/drivers/nvme/host/ | 01:42 |
| aberrant | -rw-r--r-- root/root 163713 2019-12-16 15:39 ./lib/modules/5.3.10+/kernel/drivers/nvme/host/nvme-core.ko | 01:42 |
| aberrant | that's dpkg -c | 01:42 |
| connor_k | Okay cool, looks like they’re all rolled up into *image*.deb | 01:42 |
| aberrant | does that mean the modules are loaded? | 01:42 |
| aberrant | ok | 01:43 |
| aberrant | is that the right image deb? | 01:43 |
| aberrant | I don't want dbg, right? | 01:43 |
| connor_k | I think the *modules*.deb is purely an ubuntu artifact with how the scripts are set up | 01:43 |
| connor_k | Yes that’s the right deb | 01:43 |
| aberrant | linux-headers-5.3.10+_5.3.10+-1_amd64.deb linux-image-5.3.10+_5.3.10+-1_amd64.deb | 01:43 |
| aberrant | linux-image-5.3.10+-dbg_5.3.10+-1_amd64.deb linux-libc-dev_5.3.10+-1_amd64.deb | 01:43 |
| connor_k | Dbg will only be helpful if you want to run that kernel under a debugger | 01:43 |
| aberrant | those are my choices | 01:43 |
| aberrant | second one, I guess. | 01:43 |
| connor_k | Yeah | 01:43 |
| aberrant | ok, now a dpkg -i on the HV, right? | 01:44 |
| aberrant | wish me luck. | 01:44 |
| connor_k | Good luck! | 01:44 |
| aberrant | W: Possible missing firmware /lib/firmware/amdgpu/vega20_ta.bin for module amdgpu | 01:45 |
| aberrant | W: Possible missing firmware /lib/firmware/amdgpu/navi10_mes.bin for module amdgpu | 01:45 |
| aberrant | I seem to recall having that earlier too | 01:45 |
| aberrant | so I'm going from 5.3.0 to 5.3.10. | 01:45 |
| aberrant | will be back after reboot, hopefully. :) | 01:45 |
| * aberrant waves | 01:45 | |
| connor_k | o/ | 01:47 |
| aberrant | w000000 | 01:50 |
| aberrant | seth@elemental:~$ sudo fstrim -v / | 01:50 |
| aberrant | seth@elemental:~$ sudo fstrim -v / | 01:50 |
| aberrant | damnit, that's not pasting | 01:50 |
| aberrant | suffice to say it works | 01:50 |
| aberrant | we need to get this patch into the kernel :) | 01:51 |
| sarnold | TIL there's a -v to fstrim :) | 01:51 |
| aberrant | /: 758.3 GiB (814159003648 bytes) trimmed | 01:51 |
| aberrant | there | 01:51 |
| aberrant | I'll update the bug report. | 01:52 |
| sarnold | hmm which irc client do you have? I thuoght most? all? had paste detection to handle a leading / in a paste correctly | 01:52 |
| sarnold | that might be worth a bug report for your irc client, heh | 01:53 |
| connor_k | Nice job aberrant!! | 01:53 |
| aberrant | sarnold: I'm using irssi | 01:55 |
| aberrant | connor_k: I couldn't have done it without you. Thanks so much! | 01:55 |
| sarnold | hm. now I've got to try.. :) | 01:55 |
| connor_k | What’s the bug number, aberrant? | 01:55 |
| aberrant | 1856603 | 01:55 |
| sarnold | # fstrim -v / | 01:56 |
| sarnold | /: 6.7 GiB (7215800320 bytes) trimmed | 01:56 |
| sarnold | irssi 0.8.19-1ubuntu1.9 on this machine | 01:57 |
| aberrant | sarnold: from what I understand the fstrim issue only manifests in certain nvme drives that don't follow the spec precisely. | 01:58 |
| aberrant | 758.3 GiB trimmed seems like an awful lot though. | 01:58 |
| sarnold | aberrant: heh, I was more just interested in the / leading char thing, the actual issue you and connor_k are discussing I haven't followed at all, hehe | 01:59 |
| aberrant | I don't think I've gone past 20% utilization on the drive. | 01:59 |
| aberrant | hahahaha | 01:59 |
| connor_k | Cool! I wrote it down and can look at it tomorrow for SRU’ing the patch into the kernel | 01:59 |
| sarnold | aberrant: how long has it been since you've done an fstrim on this system? what kind of write churn does it have? do you have the weekly fstrim timers running correctly? | 01:59 |
| aberrant | CTCP VERSION reply from aberrant: irssi v1.2.1-1ubuntu2 | 01:59 |
| aberrant | sarnold: the machine is less than a week old. I've never done an fstrim on it. | 02:00 |
| sarnold | 700G trimmed *does* feel like a huge trim if you're getting it done weekly already.. | 02:00 |
| sarnold | sheeeeeesh | 02:00 |
| aberrant | I set up some vms on it, and transferred a bunch of data. | 02:00 |
| aberrant | but currently I'm at 19% utilization | 02:00 |
| aberrant | (1TB) | 02:01 |
| aberrant | I wonder if the first fstrim on a brand new disk is somehow large. The subsequent one I did was 0 GiB. | 02:01 |
| aberrant | oh, look | 02:01 |
| aberrant | that's roughly the size of the total free space | 02:03 |
| sarnold | yeah, any more and I'd have been very worried :) | 02:03 |
| aberrant | so maybe it had to do a complete fstrim on the entire free list. | 02:03 |
| sarnold | it's possible that the 'first' fstrim on the filesystem does have to start from scratch and trim it all, whether or not it'd been used | 02:03 |
| sarnold | 250ish gigs, though, the average data would only need to be overwritten three times.. between write amplifications on small writes, OS updates on host and guests.. maybe 700-ish gigs of dirtied but no longer needed data isn't crazy for a 250-ish gig used system | 02:05 |
| sarnold | I shudder to think about eg atime updates on all those bloody files. relatime is a good thing, but even then.. | 02:05 |
| aberrant | I'm mounting relatime | 02:06 |
| aberrant | let's see what happens next sunday :) | 02:07 |
| sarnold | :) | 02:07 |
| aberrant | this channel is fantastic. Thanks for all the support here. | 02:07 |
| sarnold | hmm does the timer use fstrim -v? or fstrim? or .. just run the ioctls raw? | 02:07 |
| aberrant | as it turns out I have to RMA my motherboard. | 02:07 |
| aberrant | it won't take a BIOS update. It's stuck on the penultimate version. | 02:07 |
| sarnold | here's the logs from three of my machines http://paste.ubuntu.com/p/GGJHQKFDJj/ | 02:10 |
| sarnold | that's frustrating :( | 02:11 |
| aberrant | yeah, so I confirmed: if I add the trimmed GiB to the used GiB I get exactly the capacity of the disk | 02:15 |
| aberrant | so the first trim probably trims the entire free space | 02:15 |
| aberrant | 758.3 + 158 | 02:16 |
| aberrant | well, not *exactly* but close enough for government work | 02:17 |
| aberrant | ok. That's enough stress for one day. thanks again. Have a great evening, all. | 02:20 |

| aberrant | morning all :) | 18:23 |
| aberrant | after that patch everything is wonderful. | 18:24 |
| tharrrk | hi there. may i have a question regd. mainline kernels here or is there a better channel to ask? | 20:34 |
| sarnold | this may be fine, but there's also a #kernelnewbies on irc.oftc.net that's more about kernel programming. maybe ask and see what happens :) | 20:36 |
| tharrrk | cool thanks | 20:37 |
| tharrrk | so, all builds on kernel.ubuntu.com/~kernel-ppa/mainline/ from v5.3.7 failed for i386. Is that intentional? I mean, i386 is kind of dead these days but if there is a build recipe i think it should either build successfully or it should go away... If there's something i could help with..? | 20:42 |
| sarnold | heh that's indeed one that wouldn't be useful for #kernelnewbies :) | 20:49 |
| tharrrk | :) | 20:51 |
