I am putting together an Courier IMAP server and would like to squeeze
all the performance I can from the array as there will almost 200
persons collecting mail from the machine. As you may know Courier
stores all mail as individual files, averaging in our environment
between 2 and 4K each.
The RAID 5 array is across 7 disks on a FC controller. Would anyone
have a recommended set of arguments to pass mkfs.xfs while creating the
fs?
the md raid was created using a chunk size of 32, you think this is ok
or should it be smaller?
I was going to use this line to create the xfs fs:
mkfs.xfs -f -b size=2048k -d agcount=16 /dev/md0
also I am considering putting the metadata log on another device.
any thoughts on this would be really appreciated.
thanks for your time,
greg
