'Some' partitions showing Total size less than the actual .

Hi ,

We noticed that some partitions of our filesystem being monitored showed the 'Total size' to be much lesser than what is the actual .

Note: The difference is much more than what may be due to issues of snmpversus df

ie Filesystem A has 3T , but Zenoss monitoring shows only 960G

Note: There are 5 mounts being monitored , but only 2 of them are displaying the total incorrectly The other 4 are pretty accurate .

The host being monitored is a Linux host , and the version of Zenoss we use is 4.2.3 .

If anyone has seen something similar or knows whats happening , would really appreciate it .

( Have not found anything about this on the internet so far .. )

Thanks a lot in advance ,

Regards ,

Taher .
