Now,when sent a cap msg to inode/snap, it don't include the ctime of
inode/snap.So make the mtime ahead of ctime.
BTY,for snap, i'm not exactly send the ctime of snap or null.

It hasn't changed since the patch I posted inline 4 days ago (same as
the one that went out to linux-cachefs mailing list). You can also get

I think we should be able to cover most cases by adding an interface like:
setint minimum_to_read(const setint want_to_read, const setint
available_chunks);
which returns the smallest set required to read/rebuild the chunks in
want_to_read given the chunks in available_chunks. Alternately, we

Okay, my analysis of the patch:
Looking at your index structure, ceph has per-fsid indices under the top

Scott,
You make a good point comparing (5/3) RS with Xorbas, but a small nit:
The I/O to recover from a single failure for both schemes is 5 blocks so it is
as efficient as Xorbas.
Maybe not. You would probably issue I/O to all the remaining 7 blocks to cover
for the possibility of double
