mount -t xfs -o rw,noatime,nodiratime,logbufs=8
nodiratime is redundant, noatime will do both.

Hi,
Are there any 'optimal' settings for XFS formatting under GlusterFS? The
storage will be used for Virtual Disk storage, virtual disk size from 8GB to
100 GB in size.
One of the VM's (separate gluster volume) will be running MSSQL server (4K
reads and writes). The other will be running
Hi,
I've seen that EXT4 has better random I/O performance than XFS,
especially on small reads and writes. For large sequential reads and
writes XFS is a little bit better. For really large sequential reads
and write EXT4 and XFS are about the same. I used to format XFS using
this:
mkfs.xfs -l
Try using ext4 if you can. Small file read performance will be MUCH
better than xfs.
On the other hand, you might wanna run some benchmark tests which
resemble your workload, to compare xfs vs ext4 both with and without
glusterfs.

The issues with both random-access performance and fsck times vary a lot
according to *exactly* which version of each you're using. I'm in the same
Yup, our tests recently were done directly to XFS using bonnie,
iozone, fio, and tiobench on centos6, which is not using the most
bleeding edge

Basic thumb rule
RAID 5 , 64k stripe size, use the following. If you have larger files
go further.
# xfs, 5 disks, 64K stripe, units in 512-byte sectors
mkfs -txfs -d sunit=$((64*2)) -d swidth=$((5*64*2))
Use for better memory alignment with Scheduler
