Managing guest VMs on Fedora KVM host
by Philip Prindeville 25 Aug '24

25 Aug '24

Hi, I have some Linux VMs that are running out of space. Is there a tool I can use to manage their .IMG or .QCOW files? In particular, I have a build farm with some Linux machines using LVM filesystems, and I need to resize their PV’s and LV’s, grow the ext4 or xfs filesystems, etc. inside those .IMG and .QCOW files. In some cases the partition I want to grow is sandwiched between others. What’s available? I saw a Redhat Access blog that mentioned virt-filesystems, but it doesn’t seem to be built for my OS. Thanks, -Philip

OT: UEFI settings for DDR5 RAM
by Patrick O'Callaghan 24 Aug '24

24 Aug '24

Apologies in advance if this is too OT. I recently installed a new system based on an MSI B650-P motherboard with an AMD Ryzen 7600 and Corsair DDR5 RAM. The RAM specs show a recommended frequency of 5200 MHz, but the UEFI screen shows it running at 4800MHz (even though it also notes the correct spec). Here's a screenshot link: https://drive.google.com/file/d/1Z21GpYtO9jgNA5RDVh6qz2EShbVCRWCw/view?usp=… The MSI docs are atrocious and I can't see any way of changing the DRAM frequency. Not a big deal really but if anyone has any ideas I'd appreciate the feedback. poc

Secondary SSH
by Dave Close 24 Aug '24

24 Aug '24

I have several local machines that, while working, I frequently use ssh to do something on a different machine. While on that second machine, I may even use ssh to do something on a third machine. All of this works exactly as it should. If I use JuiceSSH on my Android phone to contact one of my local machines, that also works well. But if, while connected, I try to start an ssh session to a different local machine, it simply times out. The last message seen with "ssh -vvv" is, "debug3: ssh_get_authentication_socket_path:". Up to that point, the output of "ssh -vvv" is identical when running successfully between two local machines without using JuiceSSH. If instead of trying to start an ssh session immediately upon connecting with JuiceSSH, I first use sudo to become root on the local machine and then try to ssh to another local machine, that works perfectly (provided, of course, that the second machine permits root ssh login). The second ssh session also works if I simply run "sudo su {me} -c ssh" so becoming root isn't the key. Summary: JuiceSSH -> user@machine1 -> user@machine2 :: FAILS JuiceSSH -> user@machine1 -> sudo on machine1 -> user@machine2 :: WORKS I've examined the output of the set command for all of these situations and can't find any variables that are different that seem relevant. (Of course, $PPID and similar variables are different.) Can anyone suggest what could be the issue? Or what other tests might be helpful? -- Dave Close, Compata, Irvine CA +1 714 434 7359 dave(a)compata.com dhclose(a)alumni.caltech.edu "Life resembles a novel more often than novels resemble life." -- George Sand

Unexpected laptop behavior
by Paolo Galtieri 24 Aug '24

24 Aug '24

I normally run my laptop on AC power. I also have it plugged into a UPS. Today the power went out. The power applet on the mate desktop reported I had 7298 hours of laptop run time and 5 minutes of UPS. The laptop then powered itself off. Can someone tell me what I might have have misconfigured?

Hibernation vs Secure Boot
by Patrick O'Callaghan 23 Aug '24

23 Aug '24

I keep getting this in the journal: Lockdown: systemd-logind: hibernation is restricted; see man kernel_lockdown.7 and a glance at the man page reveals that hibernation and secure boot don't play nice unless the swap image filesystem is encrypted. My immediate reaction is to disable Secure Boot, but I'd like to know if there's an easy workaround, bearing in mind that my system is set to hibernate overnight and wake up automatically in the morning, without me having to type in a password. poc

boot stops before startx....
by François Patte 23 Aug '24

23 Aug '24

Bonjour, Yesterday I updated my fc40 installation. I have an nvidia GPU with nvidia driver from rpm-fusion. I think that the akmod compilation of the driver went wrong and I could not boot until the graphical login screen: the screen remains black and nothing was possible to be done, even accessing to consol via ctrl-alt-F2-to-12. So I booted in rescue mode and erased all nvidia stuff (except firmware) and modified the kernel line in grub (suppressing "blacklist nouveau") and rebooted. Now, I can boot but not to graphical mode: at the end, I have to switch to consol (Ctrl-Alt F2), login and startx. How can get a full boot upto graphical mode again? Thank you. -- François Patte UFR de mathématiques et informatique Laboratoire CNRS MAP5, UMR 8145 Université Paris Descartes 45, rue des Saints Pères F-75270 Paris Cedex 06 Tél. +33 (0)6 7892 5822 http://www.math-info.univ-paris5.fr/~patte

dracut + LUKS = no boot? (now fine, issues a month ago)
by User of Fedoras 22 Aug '24

22 Aug '24

Hi, I had changed from Fedora to openSUSE due to an error on LUKS during boot (it would not see the correct devices, dracut would timeout). I could boot using an older kernel but couldn't figure out what the issue was/hadn't had the patience. Yesterday it happened on openSUSE and, in that case, no kernel would boot. So, again, I returned to Fedora. Do note the same thing had happened on another computer. This was approximately 1 month ago. No-one else seems to have had this issue. I've since reinstalled Fedora 40 so now my system is stable and working fine. Still, it puzzles me, so, does anyone have any hint of what may have gone wrong? Spurious internet searches suggested: buggy `blkid` update resulting in buggy `blkid` output which induced `grub-mkconfig` to output boot options missing the necessary UUID necessary for unlocking the correct partitions. But those results were from about a few months ago. Just FYI, my current, working, install was like this: I installed Fedora 39, upgraded to latest packages excluding=blkid, dracut, kernel, kernel-core-modules, kernel-core-extras, upgraded to all latest on 39, upgraded to Fedora 40 and the bug didn't happen again. Thanks, User of Fedoras

Weird issue with kernel 6.10: notebook won't stay asleep
by Chris Adams 20 Aug '24

20 Aug '24

On my Thinkpad T14s Gen 4 AMD with Fedora 40, when I am using it unplugged and close the lid to sleep, it wakes back up when I plug it in to charge. This didn't happen with 6.9 and before. Not really sure how to debug this; I opened a BZ, but also curious if anybody else is seeing something similar (to see if there's common hardware). https://bugzilla.redhat.com/show_bug.cgi?id=2306298 -- Chris Adams <linux(a)cmadams.net>

raid automatic resync... where is the command?
by François Patte 18 Aug '24

18 Aug '24

Bonjour, I installed f40 with raid1 partitions. Every sunday an automatic program resync the partitions and a lot of programs "pedal in the sauerkraut" (french idiom) because of this automatic resync... I have looked in cron.d directory, cron.weekly, and other cron program in order to disable this resync which lasts for hours as soon as you have high terabit disks. How can I disable this? (And what could the issue?) Thank you. -- François Patte UFR de mathématiques et informatique Laboratoire CNRS MAP5, UMR 8145 Université Paris Descartes 45, rue des Saints Pères F-75270 Paris Cedex 06 Tél. +33 (0)6 7892 5822 http://www.math-info.univ-paris5.fr/~patte
