Pardon my incompetence - but where is the actual design document?

Comment by nasf (Inactive) [ 12/Nov/10 ]

it is under
http://jira.whamcloud.com/browse/IT-5

Please can you attach a Microsoft Word version of the document so that I can turn on change tracking and edit it.

I have attached a word version HLD (under IT-5) for inspection.

This attachment is the original design with my review comments added.
I'm very happy with the level of detail. I'd like to explore the use
of readdir+ over the wire rather than readdir + / aggregate stat in
more detail.

Updated as eeb's suggestion. Sir, please inspect it again.

Comment by nasf (Inactive) [ 06/Dec/10 ]

Currently, I more like lockless readdir+, which can much improve "ls -l" performance. I am wonder whether it can be an option for ORNL's project1 or not.
