What options are available to get a report listing of when files/directories were last accessed on a 8.1.2 Isilon (i.e last accessed time)
Unix find command?
Smartpools/Cloudpools? (can a report of this data be generated without actually moving any data?)
Isi statistics heat command?
InsightIQ (seems to only provide the top 1000 files) ?
Probably the fastest way to get a complete list would be to leverage Bob Sneed's excellent PowerWalk utility.
For the general concept of managing your data based on things like mtime/atime, ClarityNow serves that purpose and we will be incorporating that functionality into the successor to InsightIQ so while InsightIQ today cannot give you what you want, I believe the replacement product should be able to do so.
