Reiserfs and disk spindown: separate /var partition?
Hello
I would like the hard drive to spin down (on a small server
overnight, on a powerbook, etc), but want to use reiserfs. Reiserfs
prevents noflushd from working since it bypasses the filesystem
buffer for writing it's log. So what can I do?
I'm imaging this: if I manage to use ext2 for just those directories
into which something is written while the computer isn't used (system
logfiles in /var, maybe something in /tmp), and reiserfs for the
rest, there should be no writes bypassing the filesystem buffer and
thus noflushd should work.
Has anyone done this?
I've some questions:
- Are there no problems making /var (and /var/cache) and /tmp
symlinks to another partition? (Would it decrease performance?)
I think I read that kernel2.4 has a new feature for mounting stuff in
a new way, but I don't remember exactly. Could it help against using
symlinks?
- Getting it right for the boot process (should I make / reiser or
ext2?): I assume I need to have /etc, /bin and /sbin on the root
partition. What about /usr? Is there no problem mounting /var and
/tmp later? What about /boot: if using lilo, /boot doesn't have to be
in place while booting, does it?
As a related question: besides disks, are there other pieces of the
computer you can put to sleep on a server?
