Block-Layout

Block-Layout

[Johannes Schild]

Hi Guys,

after i got the Object-Layout to work (Thanks to Boaz :D)
My next goal to achieve is the Block-Layout.
I know its deprecated, Boaz told me too, but i need it for my paper.
Could someone tell me which was the last working kernel and sources which works?

I would be very grateful if someone has further tips/tricks or documentation ;)


Thanks in advance


Best Regards

Johannes

You mean the Server right? The client is very much alive.

I'm not sure what was the last spnfsd-blocks that worked? Jim?

I don't know.  I would ask Benny.

So lets ask Benny ;)

Can you give me a hint about the most usable block-layout code?

Re: Block-Layout

[Benny Halevy]

Sorry for the late response.
Unfortunately, I don't think the reference server implementation could ever work
reliably for writes. The gist of it is that it uses fallocate() to allocate new blocks
and these are marked unintialized.  Since LAYOUTCOMMIT is not handled by the file system
they are never marked as initialized and therefore they are read as containing zero
by the MDS.  So, for read-only, you can try pnfs-all-3.3.
