Description Miroslav Lachman 2024-04-16 11:28:57 UTC 
I have a symlink from /var/crash to /vol0/crash on another partition and when I tried to check the directory usage in /var, it failed with an error:

# du -d 1 -h /var/
4.0K    /var/.snap
 24K    /var/mail
 12K    /var/audit
du: fts_read: No such file or directory

I added -x to not traverse filesystem, then it works

# du -d 1 -h -x /var/
4.0K    /var/.snap
 24K    /var/mail
 12K    /var/audit
180K    /var/run
 15M    /var/backups
4.0K    /var/preserve
8.0K    /var/msgs
4.0K    /var/heimdal
713M    /var/cache
 41M    /var/db
8.7M    /var/tmp
228K    /var/spool
 46M    /var/account
4.0K    /var/authpf
 28K    /var/yp
4.0K    /var/rwho
 28K    /var/cron
892M    /var/log
4.0K    /var/empty
 12K    /var/at
 32K    /var/unbound
4.0K    /var/games
4.0K    /var/acme_sh
1.7G    /var/

But I think it should not ends by the error or the error messages should be more specific. The -x was just my blind try.

This is on FreeBSD 13.2-RELEASE-p11 amd64 GENERIC with UFS filesystems.
