This patch is an experimental. So Please check with caution.
Current sheepdog stores whole objects in single directory like
"/var/lib/sheepdog/obj"
This mechanism is difficult to handle massive files when increasing cluster
volume.
In particular, inode object having special informations about VDI,
so it is preferable to divide directory.
New storage type is named "split"
It separates the inode object and data object to some directory.
How to use.
specify --store option at the time dog cluster format
dog cluster format --store split
I don't have time to review the code but I'd like to give you some advices:
Thank you for advice.
- The patch aims to bring hierachy to the store. How about the name 'tree_store'
which implies a tree structure and use "tree" as the driver name
It's good.
- You should place the new store code into a standalone file, named
"xxx_store.c".
It is correct point out. I'll try that way.
However, it seems not simple because md.c and plain_sotre.c
using the function each other.
