Kernel
Upstream recommends using XFS or ext4 in production. brtfs is possible, but not recommended at this time for production environments.
Enable extended attributes for the filesystem in the kernel.
Setup Disks
Use a separate drive for the OS and the data wherever possible. Otherwise, split them up on individual partitions.
Use hdparm to disable write caching on the drive:
hdparm -W 0 /dev/sda 0
For ext4 filesystems, enable omap support in ceph.conf; optional for xfs or ext4.
filestore xattr use omap = true
