There are 141 tips in the FreeBSD tips file that is displayed by fortune every time you log into a FreeBSD system.
root@geonosis:~ # grep -E '^%' /usr/share/games/fortune/freebsd-tips | wc -l
141
Most of the time, I know the tips very well. Sometime, however, I do learn a new thing.Today I Learned thatTo set a quota of 10 GB for the user named foo on a ZFS dataset, run the
following command:
# zfs set userquota@foo=10G pool/home/foo
The zfs userspace command can display the quota and current space usage:
# zfs userspace pool/home/foo
To unset a quota, assign "none" as the value.

This is actually two tips in one. First, is the userquota in a filesystem, and the second one is how to see these quotas, which I had no idea about.So I tried running it on one of my larger systemsroot@geonosis:~ # zfs list genomic/abi/proj/cfdna

I don’t integrate our storage systems with LDAP, instead we just use the UIDs in permissions, but I can check who that is on another system.antranigv@ssh-02:~$ id -nu 10039

Time to inform anahit that she has the record for most used storage in our largest project That’s all folks…
