"there are more consumer NAS devices running XFS in the world than there are servers running XFS"

BTW, can you point me to the reasons for chosing XFS in such an environment? The kernel module for XFS is huge. 1.7MB on the SL 6.1 machine in front of me. By "consumer" are you referring to the sub-$200 stuff that can be bought at, say, BEST BUY? I would be very interested in the rationale. I have a few Buffalo router/NAS devices. 32MB flash/64MB ram. USB 2.0. What would you say the advantages of running XFS rather than EXT4 might be on this device?

XFS is very reliable and performs extremely consistently over the expected life of such devices? And XFS tends to perform better on NAS workloads than ext3/4 on the same hardware? And that mkfs doesn't make the user wait for a *long time* before they can use the device? And that there are tools in xfsprogs designed to optmise the manufacturing process (e.g. xfs_copy), and so on?

Yes, exactly. Brands like thecus, netgear, dlink, etc either use XFS by default or recommend it over ext3/4 in most situations.

I'm pretty sure they use XFS, too. Certainly google indicates that even the low end buffalo NAS boxes go faster with XFS on them....
