Much to my surprise, XFS produces quite a lot of wakeups in kernel 3.2.9. On every mounted filesystem, the associated xfsaild will wake up 20 times per second, when the filesystem is sufficiently loaded, it will never wake up. The filesystems are mounted with defaults, I'm seeing the problem on virtual IDE drives in virtual machines and SSD < dmcrypt < LVM < XFS stacks. Am I doing something wrong, or am I seeing expected behaviour in XFS? -- Sean _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
