I want to set up raid 5; I have four partitions on four disks:
hde1, hdf1, hdg1, hdh1 : each has 50000 Megabyte.
1. Could anyone please recommend which chunk - size I should use in the
/etc/raidtab?
Newer disks like larger chunk sizes but I think 64 or 128 will suit you
fine. 256 might be a option on larger disks.
2. After I have made "mkraid /dev/md0", should I format /dev/md0 with
special parameters????????????
mkfs.xfs has some knowledge about software raid modules and will
automagically do this for you.
If you are going to have lot's of files and creating deleting it might be
worth something to mkfs.xfs your fs with mkfs.xfs -l size=32768 /dev/foo
and mount that raid with logbufs=8 if you have a lot of memory.
