** Description changed:
[Impact]
Logwatch fails to print info for ZFS due to invalid paths to binaries.
[Test Case]
With ZFS installed, run logwatch and note the missing ZFS information.
+
+ $ sudo apt-get install zfsutils-linux
+ $ sudo logwatch --detail Low --range all --service zz-zfs --output stdout
+
+ In the bugged version, this produces no output.
+
+ With a successful configuration, you will see something such as:
+
+ --------------------- ZFS Report Begin ------------------------
+
+ /dev/zfs and /proc/self/mounts are required.
+ Try running 'udevadm trigger' and 'mount -t proc proc /proc' as root.
+
+ ---------------------- ZFS Report End -------------------------
[Regression Potential]
Since logwatch filters logs for errors pertinent to administrators,
standard things to watch out for are undesired changes in this filtering
behavior, such as flagging or failing to flag issues differently than
before, other than the specific messages being filtered with this
change.
[Discussion]
In /usr/share/logwatch/scripts/services/zz-zfs line 54 and 55 are the
following.
my $pathto_zpool = $ENV{'pathto_zpool'} || '/usr/sbin/zpool';
my $pathto_zfs = $ENV{'pathto_zfs'} || '/usr/sbin/zfs';
In Ubuntu, the zfs utilities are in /sbin, not /usr/sbin. This causes
logwatch to not print info for ZFS even if you're using it.
The fix is just to point to /sbin instead. This is what fixed it for me.
my $pathto_zpool = $ENV{'pathto_zpool'} || '/sbin/zpool';
my $pathto_zfs = $ENV{'pathto_zfs'} || '/sbin/zfs';
