I use kernel-rt-4.18.0-329.rt7.110.el8.x86_64(RHEL8.5) to test it again. It works as normal.

Maybe it's tuned bug, but more probably it is grub2 bug. The tuned-2.13.0 directly calls grub2-editenv and doesn't touch the grubenv otherwise. Thus, it seems it's the grub2-editenv which fails for some reason and erases the grubenv content. Unfortunately I am unable to reproduce the problem, the reproducer doesn't work for me. Could you please run the following commands instead of the last tuned-adm in your reproducer and provide the tuned.log: # systemctl stop tuned # tuned-adm profile realtime-virtual-host # tuned -D 2>&1 | tee tuned.log Also am I right that this problem is reproducible only on the RHEL-8.2/RHEL-8.3 and it's not reproducible on the RHEL-8.4/8.5? Hello Jaroslav
I have been test on rhel8.4.z/rhel8.5 and rhel8.2.z RT kernel. Only found rhel8.2.z can be reproduced this issue.
I follow you step, here is my test step as below. More tuned log please check attachment.

Cannot talk to Tuned daemon via DBus. Is Tuned daemon running?

This server still lend you until no more value information be found. > > B.R > Minxi Do I understand correctly that this issue only happens with 8.2.z and no with other RHEL 8 minor versions ? yes, this issue only happens on 8.2.z and no with other RHEL8. I test kernel-rt-4.18.0-193.64.1.rt13.115.el8_2 and kernel-rt-4.18.0-193.60.2.rt13.112.el8_2, all of kernel occur this issue. This is with a legacy BIOS system correct? Could you please try to update your GRUB core image ? For example with the following command: grub2-install /dev/X (replace X for the block device that contains your GRUB installation). I believe this is a duplicate of bug #1761496. I check bug #1761496, and this issue fixes in grub2-2.02-83.el8 on rhel8.3. Actually when I use grub2-2.02-90 can't find this issue. So In the future, rhel8.2.z will contain a fixed grub version?

It does contain the fix but the problem is that the GRUB core image that is installed in the GRUB embedding area (the gap between the MBR and the start of the first partition) is not updated automatically on package upgrade. So to fix the grub2-install command has to be executed (as mentioned in the Comment 17). If you can confirm that the error can't be reproduced after grub2-install, then I think this BZ should be closed as duplicated of bug #1761496. |
