| 18:07 | <SysadmOFF> Good evening
| |
| 18:08 | im here to ask help with ltsp
| |
| 18:08 | i have tgz with linux system inside. Trying to boot with ltsp but no luck.
| |
| 18:09 | Retrying nfs mount...nfsmount can`t parse ip address
| |
| 18:09 | ......
| |
| 18:09 | Done..
| |
| 18:09 | Image doesnt exist /root/images/dyn_nowifi.img
| |
| 18:10 | actually - image not in that folder. but why it searching in root?(
| |
| 18:13 | <vagrantc> that's where the initramfs mounts it
| |
| 18:14 | but you have a .tgz ... a gzipped tarball ? you would need to convert that to a filesystem image
| |
| 18:14 | SysadmOFF has left IRC (SysadmOFF!~SysadmOFF@188.138.239.8, Quit: Client closed) | |
| 18:29 | SysadmOFF has joined IRC (SysadmOFF!~SysadmOFF@188.138.239.8) | |
| 18:29 | <SysadmOFF> im unpacked tgz
| |
| 18:30 | and exec "ltsp image -m "-comp zstd" dyn"
| |
| 18:30 | dyn its a folder with linux folders from root(etc,root,usr,bin )
| |
| 18:30 | <vagrantc> so shouldn't it be configured to look for dyn.img instead of dyn_nowifi.img
| |
| 18:30 | ?
| |
| 18:30 | <SysadmOFF> i have two versions
| |
| 18:31 | so ia have both dyn.img and dyn_nowifi.img
| |
| 18:31 | <vagrantc> and where are they on the server?
| |
| 18:31 | in /srv/ltsp/images ?
| |
| 18:31 | <SysadmOFF> in /srv/ltsp/images/dyn.img
| |
| 18:32 | <vagrantc> do you get a shell when it fails to boot? is there anything in /root/ ?
| |
| 18:32 | <SysadmOFF> and im choosing dyn.img instead of dyn in PXE boot menu
| |
| 18:33 | all of three files sucesfuly downloaded during boot
| |
| 18:33 | yes,i have a shell
| |
| 18:34 | <vagrantc> so what is in /root ... is there a /root/images ? what is in /root/images ?
| |
| 18:34 | ls /root
| |
| 18:34 | <SysadmOFF> waiting while a lot of messages:
| |
| 18:34 | "Begin Retrying nfs mount...nfsmount can`t parse ip address ''"
| |
| 18:34 | <vagrantc> ls /root/images
| |
| 18:34 | <SysadmOFF> it can take a minute of two (
| |
| 18:34 | <vagrantc> ok, sounds like you have an NFS problem
| |
| 18:34 | cat /proc/cmdline
| |
| 18:35 | also would be useful
| |
| 18:35 | <SysadmOFF> i have booted in linux mint 21, and sucesfully created bootable image. with ltsp image /
| |
| 18:35 | sec
| |
| 18:35 | <vagrantc> what is this .tgz you're trying to use?
| |
| 18:35 | <SysadmOFF> this tgz is from previous sysadmin, maybe used with foreman. I dont know.
| |
| 18:36 | ok. few times clicked CTRL+C and i have this:
| |
| 18:36 | aborting ltsp
| |
| 18:36 | ltsp boot erro
| |
| 18:36 | ah,i dont have a shell
| |
| 18:36 | enable debug shell for triubleshoot
| |
| 18:37 | <vagrantc> first, figure out what your image is made out of ... it may need support added or something
| |
| 18:37 | is it a custom mint build? ubuntu? fedora? ??
| |
| 18:37 | some stranger thing?
| |
| 18:38 | what kernel is it using? does it have support for nfs built-in? as modules?
| |
| 18:39 | <SysadmOFF> ubuntu 18.04.06 inside, and its a diskless image
| |
| 18:39 | <vagrantc> this makes it sound like the kernel doesn't have the features needed "Retrying nfs mount...nfsmount can`t parse ip address"
| |
| 18:39 | <SysadmOFF> should have nfs, because it should mount userdir via nfs and ldap auth
| |
| 18:40 | fstab looks like this
| |
| 18:40 | tmpfs /tmp tmpfs defaults 0 0
| |
| 18:40 | tmpfs /aufs tmpfs defaults 0 0
| |
| 18:40 | tmpfs /var/tmp tmpfs defaults 0 0
| |
| 18:40 | tmpfs /home tmpfs defaults 0 0
| |
| 18:40 | tmpfs /var/log tmpfs defaults 0 0
| |
| 18:40 | tmpfs /var/spool/cups tmpfs defaults 0 0
| |
| 18:40 | <vagrantc> you're at a shell at the client?
| |
| 18:40 | <SysadmOFF> no,just reading unpacked tgz
| |
| 18:40 | will add debug to ipxe and reboot
| |
| 18:41 | <vagrantc> aufs ... haven't seen that in a long time
| |
| 18:42 | so this is some custom-built diskelss image thing built out of ubuntu 18.04 ?
| |
| 18:43 | <SysadmOFF> looks like yes
| |
| 18:44 | there is modules file in intiramfs:
| |
| 18:44 | iwlwifi
| |
| 18:44 | iwlmvm
| |
| 18:44 | ccm
| |
| 18:44 | first two is for wi-fi
| |
| 18:44 | ccm i think its a crypto module for WI-FI also
| |
| 18:45 | so no modules for aufs there
| |
| 18:46 | NFSROOT=auto in initramfs.conf
| |
| 18:47 | "set cmdline_method root=/dev/nfs nfsroot=${srv}:/srv/ltsp ltsp.image=images/${img}.img loop.max_part=9 debug"
| |
| 18:47 | and not it stuck before nfs error
| |
| 18:58 | no shell after an error
| |
| 19:01 | <alkisg> SysadmOFF: can you upload a video of the boot process?
| |
| 19:07 | <SysadmOFF> its not possible to send it via chat?
| |
| 19:11 | uploading in progrsss
| |
| 19:11 | <alkisg> The video? If you're using matrix, yes, but if you're using irc, you'll need to upload it somewhere e.g. google drive, and paste the link
| |
| 19:12 | <SysadmOFF> i saw one interesting thing during boot - rootpath : is empty and rootserver 192.168.10.254. , but i dont have such host.
| |
| 19:12 | <alkisg> Btw wouldn't it be easier to re-create a new 22.04 Ubuntu image, instead of trying to revive an unknown 18.04 image? If it has aufs, it might be broken in weird ways...
| |
| 19:14 | <SysadmOFF> im searching for lightwieght and fast system for diskless usage. So im checking 5-10 different OS and comparing time to boot kernel, to boot login etc. Want to find nice and fast. Like ClearOS or ELementary, or Mint
| |
| 19:14 | and this image is very light and should be fast. I thought it will be easy job, but im working on this during alsmost a week =((
| |
| 19:15 | video 1
| |
| 19:15 | "https://temp.sh/WAZio/Screen%20Recording%202022-08-16%20at%2022.08.18.mov"
| |
| 19:15 | <vagrantc> have you considered the time it takes to make it work in your speed calculations? :)
| |
| 19:17 | <SysadmOFF> =D you definitely right, but i need to do this task. I cannot just stop. Its a first time when im asking for help, i prefer to deal with issue with myself. Its an experience. Bad or good - no matter )
| |
| 19:17 | but yes, im stupid and wasting time .My and yours )) and im sorry ))
| |
| 19:19 | here is a screenshot of what i have after a lot of error on video
| |
| 19:19 | https://ibb.co/Ph10KW4
| |
| 19:24 | <alkisg> SysadmOFF: set DEBUG_SHELL=1 under [clients], then run sudo ltsp initrd, then reboot the client
| |
| 19:24 | When you get a shell, type `cat /run/net*.conf`, and upload a screenshot.
| |
| 19:25 | > is empty and rootserver 192.168.10.254. , but i dont have such host.
| |
| 19:25 | Isn't that your gateway? Try to ping it
| |
| 19:26 | Router=.254, ltsp server=.37, client=.52
| |
| 19:30 | <SysadmOFF> in ltsp.conf?
| |
| 19:30 | <alkisg> Yes
| |
| 19:30 | <SysadmOFF> dont have it. Will copy from share
| |
| 19:31 | <alkisg> !ltsp.conf
| |
| 19:31 | <ltspbot`> ltsp.conf: Configuration file for LTSP: https://ltsp.org/man/ltsp.conf/
| |
| 19:32 | <alkisg> (see the creation paragraph)
| |
| 19:42 | <SysadmOFF> Here is a screenshot
| |
| 19:42 | https://ibb.co/FW0QMx5
| |
| 19:45 | <alkisg> I faintly remember reporting an issue with netplan quotes, not sure if they fixed it and when
| |
| 19:45 | SysadmOFF: and what's the output of `cat /proc/cmdline` ?
| |
| 19:50 | <SysadmOFF> https://ibb.co/2N3VKBH
| |
| 19:52 | alkisg
| |
| 19:52 | <alkisg> It's fine
| |
| 19:52 | <SysadmOFF> so its a netplan issue with quotes?))
| |
| 19:52 | <alkisg> I think it's that netplan bug that I reported ages ago
| |
| 19:52 | <SysadmOFF> but netplan its a default for fresh ubuntu-based OS
| |
| 19:52 | <alkisg> I think that you just need to run apt full-upgrade inside your chroot
| |
| 19:53 | Yes, I'm not asking you to uninstall it, just to update it
| |
| 19:54 | <SysadmOFF> got it, looks like resolv.conf doesnt exist and not able to resolv mirrors
| |
| 19:54 | lets add 1.1.1.1
| |
| 19:54 | 195 upgraded, 10 newly installed, 0 to remove and 0 not upgraded.
| |
| 19:54 | Need to get 481 MB of archives.
| |
| 19:54 | not bad =\
| |
| 19:55 | <alkisg> Anyway that's all from me; good night! :)
| |
| 19:55 | <SysadmOFF> thank you!
| |
| 19:55 | will try then to ltsp image
| |
| 19:55 | right?
| |
| 19:55 | <alkisg> Right 👍️
| |
| 19:55 | <SysadmOFF> thanks,take care
| |
| 20:27 | apt full-upgrade doesn`t help
| |
| 20:28 | but why it works for mint, here is also netplan in use and active
