Hey guys,

Currently I have 2 partitions, a root and home partition, fortunately
on LVM array, I was thinking of splitting them to "/, /usr, /var, /home,
/usr/portage, /mnt/storage" the latter is to be used for Mp3z (around
12000) and movies...

I was thinking of having the below filesystem schema:
/               : ext3 (-j -O dir_index,sparse_super,filetype) (Good mkfs options ??)
/usr            : xfs (I never used it so please suggest mkfs.xfs options)
/var            : //
/home           : ext3 (-m 0 -j -O dir_index,sparse_super,filetype) (Good mkfs options ??)
/usr/portage    : ReiserFS (3? 4? options??)
/mnt/storage    : ext3 (-m 0 -j -O dir_index,sparse_super,filetype) (Good mkfs options ??)


Could you please comment/complete/change the schema above ?? I really
would like to speed up my system a little bit, My system is entirely
built on LVM array, and LVM is on DM-CRYPT so as you can see it's a
quite slow due to the encryption...

Oh one last thing, What do you suggest for a server? I have a Gentoo
server and uptime can be over 5/6 months, everytime I reboot the
server I have to manually scan the filesystem due to errors
everywhere, any suggestions??

Thanks...
