Created page with "== User quota == The /srv filesystem has usrquota enabled with the following per-user limits: soft hard /srv space: 10G 12G /srv files: 1M 1.2..."

New page

== User quota ==

The /srv filesystem has usrquota enabled with the following per-user limits:

soft hard
/srv space: 10G 12G
/srv files: 1M 1.2M

When users attempt to write beyond their hard-limit, the system call fails with a "Quota exceeded" error.

If the soft-limit is exceeded, a cronjob sends a daily notification
email to the user and to systems-logs@. This continues for a grace period
of 7 days. Aftet the grace period, offending users will be barred from
allocating any additional space until they free up some space.

== Requesting limit exensions ==

Additional space can be requested to the sysadmins, along with a motivation.
For best service, follow the canonical BOFH space extension script:

* Q: I need more space
* A: Well, why not move to Texas?

* Q: No, on my account, stupid.
* A: I didn't quite catch that. What was it that you said?

* Q: Um, I said what I wanted was more space on my account, *please*
* A: Sure, hang on. < clickety...clickety... rm -r /home/$USER > There, you've got *plenty* of space now!

== Additional info for sysadmins ==

=== Essential documentation ===
man edquota
man setquota

=== Show quota summary for all users ===
{{{
repquota -vast
}}}

=== Create quota from scratch ===
{{{
quotacheck -m -c /home
quotacheck -m -c /mail
quotaon -au
}}}

=== Reset quota limits for all users ===
{{{
cd /home
for i in *; do
# 25G 30G 1M 1.2M
setquota -u $i 26214400 31457280 1024000 1200000 /home
# 1G 1.2G 1M 1.2M
setquota -u $i 10485760 12582912 1024000 1200000 /mail
done
}}}

=== Check quota limits in cron.daily ===
See `/etc/warnquota.conf` and `/etc/quotatab`
{{{
warnquota -u -s
}}}

=== Crash recovery ===
In case of crash, theoretically one should run quotacheck to scan the
entire filesystem, recomputing the exact quota status of all users.
In practice, nothing bad happens if the values are off by a few megabytes,
so quotacheck is mostly just a waste of time.
