Hi,
I am repeating the post below, because it obviously hasn't made it to the list (at least i did not get it back from the list).
Can someone please give me some advice, because i will be setting up the discs today.
Thank you
Hi,
I am going to set up a RAID 0 array with two 250G drives, making 500G.
Which newfs parameters would you recommend for it?
As many cylinders per group as possible. I think newfs has an "infinity" setting to pick the right number.
I am afraid of ending up with a fs with Gigs of space and no inodes
left, or a fs that is heavily fragmented and slow.
Reading the newfs manpage didn't quit help me, it explains all switches
The files on the volume will be 2 MB average.
There's a "bytes per inode" setting that you can plug this figure into.
You might want to be a little more generous with inodes than that (give
yourself some elbow room). You need inodes for symlinks and directories
too.
Thank you for your reply. I have reread the manpage and would go for: - blocksize => 64 kB - fragsize => 64/8 => 8 kB - bytes/inode => 16 kB
Are these values reasonable or should i use higher values (because the disk is so large?)
Heinrich
