[gpfsug-discuss] Question about Policies

Fri Dec 27 13:56:29 GMT 2019

Hi

Thanks for your reply, once I have a set of files that are older than 30 days would I then use the migration rule to move them ?

Looking at the migration Rule syntax implies a “From” pool and a “To” pool, I only have a single pool so would I use the same pool name for From and To ? if it is the same pool
How do I specify the folder to move it to which needs to be different from the current location.

Thanks
Kevin

RULE ['RuleName'] [WHEN TimeBooleanExpression]
  MIGRATE  [COMPRESS ({'yes' | 'no' | 'lz4' | 'z'})]
    [FROM POOL 'FromPoolName']
    [THRESHOLD (HighPercentage[,LowPercentage[,PremigratePercentage]])]
    [WEIGHT (WeightExpression)]
  TO POOL 'ToPoolName'
    [LIMIT (OccupancyPercentage)]
    [REPLICATE (DataReplication)]
    [FOR FILESET ('FilesetName'[,'FilesetName']...)]
    [SHOW (['String'] SqlExpression)]
    [SIZE (numeric-sql-expression)]
    [ACTION (SqlExpression)]
    [WHERE SqlExpression]

Hi

I work for Cancer Research UK MI in Manchester UK. I am new to GPFS and have been tasked with creating a policy that will

Move files older that 30 days to a new folder within the same pool. There are a lot of files so using a policy based move will be faster.

I have read about the migration Rule but it states a source and destination pool, we only have one pool. Will it work if I define the same source and destination pool ?

Many thanks

Kevin
