There are a couple of surprises which seem to do with how the filesystems were set up (e.g. huge #s of inodes reserved but not used on OSTs) and used (different ratios of ops). The attached PDF has a summary for each filesystem containing... * Filesystem name * Ratio of MDS 1K blocks to MDS inodes Ratio of OST 1K blocks to MDS inodes Ratio of OST inodes to MDS inodes * Histogram of operation counts * Histogram of blocks total (blue) and used (red) on the MDS and all OSTs * Histogram of inodes total (blue) and used (red) on the MDS and all OSTs ...hope you find it useful.
