Need to run "zpool list" from within jail

[Stew LG]

I am trying to set up NRPE to enable remote Nagios monitoring of a new FreeNAS 0.91 system. I mostly have this working - I can connect and inquire about basic information like number of processes, users, etc.

But I can't run "zpool list" to inquire about the health of the RAIDZ, which is key to properly monitoring the box.

When I run from the main root account, it works:

Code:

[stewlg@bauer] /dev# zpool list
NAME          SIZE  ALLOC  FREE    CAP  DEDUP  HEALTH  ALTROOT
BigMediaToo  21.8T  1.11T  20.6T    5%  1.00x  ONLINE  /mnt

But when I run it from within the jail, it does not:

Code:

root@NagiosJail:/usr/local/libexec/nagios # zpool list
no pools available

I have read many, many posts but all are starting off with a fairly involved level of FreeBSD/ZFS knowledge and I'm a bit lost, and it is not obvious what I'm supposed to do, or even which files would be involved. (Do I need to modify

Code:

/etc/devfs.rules

?)

System layout, to help with names if anyone has an example for me:

- A single ZFS volume at /mnt/BigMediaToo
- A single jail called NagiosJail. Its dataset is at /mnt/BigMediaToo/JailsDataset.

Thanks very much.

The jail is like a virtual machine. Commands you run in the jail don't work on your server's physical hardware. Hence no pool was found when you ran zpool list from inside the jail.
