anyway heres the full policy...

`sensible_size` is an attribute in `body volume` (see 
https://docs.cfengine.com/docs/3.21/reference-promise-types-storage.html#sensible_size
)

I might be wrong, but It looks to me like you are listing the size of the 
filesystem. However the `storage` promise type is complaining about the 
number of bytes used. Can you try to type command `df /opt/` ?

Hi,

on one of our aix machines we get this outpput from  storage monitoring.

error: File system '/opt' is suspiciously small! (9759 bytes)

which is definitly not correct...

root@wpsap: /root # lsfs -q /opt
Name Nodename Mount Pt VFS Size Options Auto Accounting
/dev/hd10opt -- /opt jfs2 11534336 -- yes no

VIX: yes, EFS: no, ISNAPSHOT: no, MAXEXT: 0, MountGuard: no, LFF: no) 

mesage comes from here -> 
https://github.com/cfengine/core/blob/master/cf-agent/verify_storage.c#L251

skimmed through spaghetti code but i guess was unable to fully grasp whats 
going on here...

https://github.com/cfengine/core/blob/master/cf-agent/verify_storage.c#L249

where is volume.sensible_size coming from? i expected some form of statfs 
call somewhere but only found one in another unrelated universe.

https://github.com/cfengine/core/blob/master/libpromises/storage_tools.c#L84

i have an case open with the ibm guys, so please can sombady shaed some 
light on this`?
