[gpfsug-discuss] policy ilm features?

[John Hearns]

Ed,
This is not a perfect answer. You need to look at policies for this. I have been doing something similar recently.

Something like:

RULE 'list_file' EXTERNAL LIST 'all-files' EXEC '/var/mmfs/etc/mmpolicyExec-list'
RULE 'listall' list 'all-files'
SHOW( varchar(kb_allocated) || '  ' || varchar(file_size) || ' ' || varchar(misc_attributes) || ' ' || name || ' ' || fileset_name  )
WHERE REGEX(misc_attributes,'[J]')


So this policy shows the kbytes allocates, file size, the miscellaneous attributes, name and fileset name
For all files with  miscellaneous attributes of 'J'   which means 'Some data blocks might be ill replicated'

This one has been on my list a long time so I figured I'd ask here first before I open an apar or request an enhancement (most likely).

 Is there a way using the policy engine to determine the following?

-metadata replication total/current
-unbalanced file

Looking to catch things like this that stand out on my filesystem without having to run several hundred million 'mmlsattr's.

metadata replication: 1 max 2
flags:                unbalanced

Ed
