Even Sun rates their fsck at "10 minutes per gigabyte"... that would mean a 3-hour fsck on my news server with Solaris. :-/ OTOH, they have ODS 3.0 with journalled file systems which pretty much eliminates boot up delays caused by inconsistent filesystems. > There is definitely an advantage in parallelism within your > filesystems.

It takes 10 minutes to fsck the news server filesystems, and I'm pretty sure it only does one drive at a time. It would be great if multiple fsck's could run in parallel.
