[BUG] The "status.diskusage" function sometimes crashes in some distros #66646

Open meaksh opened 1 week ago

meaksh commented 1 week ago

Description

When running the status.diskusage function, it sometimes crashes, as stats cannot be obtained for some of the mounted paths. I see this happening for /proc/sys/fs/binfmt_misc which is created by systemd proc-sys-fs-binfmt_misc.automount:

# mount | grep binfmt
systemd-1 on /proc/sys/fs/binfmt_misc type autofs (rw,relatime,fd=34,pgrp=1,timeout=0,minproto=5,maxproto=5,direct,pipe_ino=1708)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,nosuid,nodev,noexec,relatime)

# salt-call --local status.diskusage
The minion function caused an exception: Traceback (most recent call last):
