There is an old idea for reducing the data required to describe file striping by using a bitmap to record which OSTs are in use. As best I can tell, this was most recently described here:
I’m curious if this has been pursued any further, if there’s a JIRA or other place that might have more info or be tracking the idea. I poked around and didn’t find anything.
In particular, this comment:
“with enough data that for each OST index set in the bitmap, a corresponding OST object FID may be computed”
Points at the difficult part of implementing this.
So, before I get too far considering this problem - Is there more out there somewhere? Hoping to avoid duplicating work!
