Hi,
I've made some histograms that visualise the F/S stats people have
so kindly sent in. 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.
Cheers,
Eric
