Hi,
(Sorry for the inconvenience caused due to previous misformatted patch, I've
most definitely figured out the problem this time. Thanks Michael, Daniel, and
Ingo for your help.)
This patch speeds up e2fsck on Ext3 significantly using a technique called
Metaclustering. Metaclustering is being discussed on LKML in some other
threads, here is the latest patch against the 2.6.23.13 stable kernel, any help
in testing and evaluating this will be greatly appreciated! While I'd direct
anyone interested in details of metaclustering to other LKML threads discussing
it, I've enclosed a brief description here:
Metaclustering refers to storing indirect blocks in clusters on a per-group
basis instead of spreading them out along with the data blocks.
Cool!
Sounds like this should also make unlink of large files faster too,
which is a much more saleable win. At Digeo we always had the problem
that deleting a multi-GB PVR file would thrash the disk to death and
give everyone else ~0 throughput.
