Hi all,
I'm getting some strange results using a policy to list all the files (well,
I'm only interested in the total size that GPFS chooses) that have not been
accessed for more than 1/2/3 etc years.
The policy rule I'm using is:
RULE 'list_old' LIST 'atime_gt_730'
WHERE DAYS(CURRENT_TIMESTAMP) -DAYS(ACCESS_TIME) > 730
..for anything over 2 years. My filesystem is 3.5 years old and we first
started migrating to it about three years ago, yet although GPFS is choosing
~400000 files that match, the total size is just north of 11000KB:
[I] Summary of Rule Applicability and File Choices:
Rule# Hit_Cnt KB_Hit Chosen KB_Chosen
KB_Ill Rule
0 453765 11776 453765 11776
0 RULE 'list_old' LIST 'atime_gt_730' WHERE(.)
I'm having a hard time believing half a million files total 11MB especially
given the very random spread of usage the system sees.
The mmapplypolicy command I'm running is:
/usr/lpp/mmfs/bin/mmapplypolicy /gpfs/path -f /gpfs/policies/ -I defer --scope
filesystem -P ./list_old_allfs.txt
The directory 'path' above is the root of the main CES share which encompasses
all my filesets.
This is my first real foray into using the policy engine so I might be doing
something silly, or misinterpreting the results, or there is simply a far
easier way to achieve my goal.
Can anyone help?
Thanks
Richard
