Hello,
I have some questions.
1. Is there any possibility of speeding up the command proocess #
fsck.reiser4 --build-fs /dev/xxx
Could the metadata be loaded into ram and processed their or is the
process entirly disk bound by I/O ?
2. Also will there a reiser4-for-2.6.39.patch in the future ?
Thanks Glenn

Yes, such possibility does exist.
Fsck can work faster if you have many subvolumes
per superblock (currently reiser4 supports only one
subvolume per superblock).

This is both, CPU and I/O bound.
The first one can be improved if we make fsck process
all subvolumes in parallel. The second one can be improved
if we map subvolumes to different physical (scsi) drives.

I hope so..
Thanks,
Edward.
