How to get it working in cron about zfs-prune-snapshots HOT 5 CLOSED

In the code where it had zfs I updated it with the full path which in my case was /sbin/zfs and now it works in cron.

from zfs-prune-snapshots.

Seems to work for me as:
copied zfs-prune-snapshots to /usr/bin
which zfs-prune-snapshots /usr/bin/zfs-prune-snapshots

added to sudo crontab -e
@daily /usr/bin/zfs-prune-snapshots -v 1s

from zfs-prune-snapshots.

Example directly from author's website:

11 0 * * * /opt/custom/bin/zfs-prune-snapshots -p automated_daily_   7d   >> /var/log/autosnap.log 2>&1
12 0 * * 0 /opt/custom/bin/zfs-prune-snapshots -p automated_weekly_  4w   >> /var/log/autosnap.log 2>&1
13 0 1 * * /opt/custom/bin/zfs-prune-snapshots -p automated_monthly_ 12M  >> /var/log/autosnap.log 2>&1
14 0 1 1 * /opt/custom/bin/zfs-prune-snapshots -p automated_yearly_  10y  >> /var/log/autosnap.log 2>&1

The issue you are seeing is caused by your crontab not having a $PATH environmental variable with zfs in it. You can fix this in multiple ways, but it's outside the scope of this zfs-prune-snapshots tool to handle managing your $PATH variable. You can:

1

Specify the PATH in your cron line (if your cron supports it), ie:

0 0 * * * PATH=/bin:/sbin:/usr/bin:/usr/sbin:/whateveryouwant zfs-prune-snapshots ...

2

Have cron fire off a "helper" script whose job it is to call zfs-prune-snapshots, ie:

0 0 * * * /path/to/my-helper-program

and my-helper-program would look something like:

#!/bin/sh
export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/whateveryouwant
exec zfs-prune-snapshots ...

3

Make sure cron is running/started with the proper PATH variable set.
