I have a system where the storage sizes are being reported incorrectly and there appears to be an issue with reading ZFS file systems being reported at all.

 

I have 4 NAS (OmniOS) servers that are ZFS based, but none of the ZFS disk space is being reported at all.

For example:

 

Filesystem                     1K-blocks       Used  Available Use% Mounted on

/usr/lib/libc/libc_hwcap1.so.1  118167920    2484288  115683632   3% /lib/libc.so.1

swap                                8399672        336    8399336   1% /etc/svc/volatile

swap                                8399428         92    8399336   1% /tmp

swap                                8399396         60    8399336   1% /var/run

rpool/export              115683728         96  115683632   1% /export

rpool/export/home  115683728         96  115683632   1% /export/home

nas01c                       4392986368         96 4392986272   1% /nas01c

nas01c/vm                5658664448 1437476772 4221187676  26% /nas01c/vm

rpool                             115683736        104  115683632   1% /rpool

nas01c/vm-data        5031018412  809830736 4221187676  17% /nas01c/vm-data

nas01c/backup_appliance        4221268004      80328 4221187676   1% /nas01c/backup_appliance

 

Yet Observium is only showing:

Mountpoint                       Size        Used     Free                       Usage %

/etc/svc/volatile               9.29GB  336kB    9.29GB                  100% 0%

/lib/libc.so.1                       112GB   2.37GB  110GB                   98% 2%

/tmp                                      9.29GB  92kB      9.29GB                  100% 0%

/var/run                               9.29GB  60kB      9.29GB                  100% 0%

 

I have another system that is mixed ZFS, XFS storage and on that one, on the “Alerts” page for the system Observium is seeing the filesystems as:

 

Mountpoint       Size        Used     Free                       Usage %

/                              281GB   138GB   142GB                   51% 49%

/backup0             757GB   7.17TB   -6.4TB                   -868% 968%

/backup1             757GB   10.1TB   -9.4TB                   -1276% 1376%

/scratch                3.64TB   903GB   2.75TB                   76% 24%

/zfsbkp                 1.64TB   128kB    1.64TB                   100% 0%

/zfsbkp/code     7.11TB   5.47TB   1.64TB                   23% 77%

 

The actual sizes are:

 

/                              281GB

/backup0             34.33TB

/backup1             34.33TB

/scratch                3.64TB

/zfsbkp                 1.64TB

/zfsbkp/code     7.11TB

 

I’ve tried deleting it and re-adding with the same result.  The system is a Debian 7.6 using XFS and ZFS file systems.

 

This is causing us to get alerts for this system when in fact it is fine.  Does anyone have any suggestions on how to fix this?
