Dynamox, if you can use the Platform API, here is how to query and compute the "usable" remaining capacity:  1. Get the "raw" available capacity excluding VHS spare as "f_bavail' from /platform/1/cluster/statfs (basically a "df")  2. To estimate the protection overhead, get       total_usage.phys_size_sum and total_usage.log_size_sum from /platform/3/fsa/results/0/directories        Notes:       - Report id "0" means: retrieve the most recent report from the Isilon, IIQ server is not involved here.       - No directory LIN given as query argument means: report stats at the toplevel dir, i.e. /ifs  3. Compute:      ratio := total_usage.phys_size_sum / total_usage.log_size_sum   (--> ratio is a number larger than one, like 1.18...)      blocksize := 8192      usable available capacity in bytes := f_bavail * blocksize / ratio    (--> so "usable" is less than "raw" in bytes)  Makes sense?  -- Peter
Hello folks,  How can i retrieve this metric either from FSA report or directly from PostgreSQL on IIQ system ? I would like to pull this value every so often via an automated process.  [IMAGE]  Thank you
