How to suppress 'leaked on vgs invocation' warning on pacman update

Support
1

Every time I run pacman -Suy the following warnings show up like 50 times:

File descriptor 6 (socket:[196741]) leaked on vgs invocation. Parent PID 33080: /usr/bin/grub-probe
File descriptor 7 (socket:[196742]) leaked on vgs invocation. Parent PID 33080: /usr/bin/grub-probe
File descriptor 8 (socket:[196745]) leaked on vgs invocation. Parent PID 33080: /usr/bin/grub-probe
File descriptor 6 (socket:[196741]) leaked on vgs invocation. Parent PID 33080: /usr/bin/grub-probe
File descriptor 7 (socket:[196742]) leaked on vgs invocation. Parent PID 33080: /usr/bin/grub-probe
File descriptor 8 (socket:[196745]) leaked on vgs invocation. Parent PID 33080: /usr/bin/grub-probe
File descriptor 6 (socket:[196741]) leaked on vgs invocation. Parent PID 33102: /usr/bin/grub-probe
File descriptor 7 (socket:[196742]) leaked on vgs invocation. Parent PID 33102: /usr/bin/grub-probe
File descriptor 8 (socket:[196745]) leaked on vgs invocation. Parent PID 33102: /usr/bin/grub-probe
File descriptor 6 (socket:[196741]) leaked on vgs invocation. Parent PID 33102: /usr/bin/grub-probe
...

Some google searches indicated that these warning are only cosmetic and can be turned off using export LVM_SUPPRESS_FD_WARNINGS=1

However, when I set this flag, the warnings still show up… what am I missing here?

:+1: Welcome to Manjaro! :+1:

That flag is for another error message:

leaked on lvextend invocation

And your error is a bug that should have been fixed years ago, so can you provide an inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information… (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)

Yeah, you’re booting from an LVM. Makes sense now. Sorry, I can’t help you any further except edit your title and add a tag to your question to attract smarter people than me…

:sob:

Just found out: adding export LVM_SUPPRESS_FD_WARNINGS=1 to the top of /usr/bin/timeshift-autosnap does suppress these warnings in most cases…
But this of course does not fix the actual issue.
