| systemdlete | This is more of a nuisance than a true bug, I think. I have suspend/resume configured on a test machine (and both work perfectly!) but during boot, whether warm or cold or resume from suspend, I always get the diskfilter warning. From what I can tell by browsing grub files and the like, it seems to be a way to skip some save_env or whatever (that's as far as I went down that rabbit hole). It is | 22:58 |
|---|---|---|
| systemdlete | a nuisance, although it does time itself out eventually. | 22:58 |
| systemdlete | Is there a way to clobber this, elegantly and correctly? | 22:59 |
| systemdlete | Supposedly, Ubuntu fixed this way back in 14.04: https://askubuntu.com/questions/468466/diskfilter-writes-are-not-supported-what-triggers-this-error#498281 | 23:00 |
| systemdlete | (not sure if I hit the right anchor in that page, sorry) | 23:00 |
| systemdlete | This is on a daedalus system. | 23:02 |
| systemdlete | it is running today's kernel update | 23:02 |
| systemdlete | 6.1.0-32 and grub, update-initramfs and other packages are all up to date. | 23:03 |
| systemdlete | It is odd that no matter how much I have searched, I can't find anything that summarizes (in human-undestandable-speak) what this "diskfilter" is | 23:03 |
| systemdlete | It may not be important, but a concise summary of what it does would be revealing as to why this is occurring. | 23:04 |
| systemdlete | the only thing I did find is that it is used by grub for lvm and raid | 23:04 |
| systemdlete | s/resume from suspend/resume from hibernate/ ^^^ | 23:09 |
| systemdlete | (resume from suspend seems to not require an entire reboot anyway) | 23:10 |
| davesp | Per "https://forums.almalinux.org/t/grub-core-disk-diskfilter-c-diskfilter-writes-are-not-supported/5048", a user fixed the issue "by recreating the grub file", presumably with "update-grub", although the specific steps weren't mentioned. (The diskfilter.c file is under "https://git.savannah.gnu.org/gitweb/?p=grub.git&view=view+git+repository".) | 23:41 |
