Hello, I'm a bit confused as the parameters for nfexpire and how they work together...
If we set an 'expire after X days' (-t) then data will be expired after that period of time. If we set an 'maximum size X' (-s) then data will be expired when it reaches that size. I assume these two run in OR mode so if EITHER are hit, files will be expired. What I'm unsure about is the 'low water mark' (-w) option -- in the manpage, it's described as "Set the water mark in % for expiring data. If a limit is hit, files get expired down to this level in % of that limit. If not set, the default is 95%." This sounds like no expiring happens until either the size or date is exceeded and then files will be removed until whichever limit is hit is reduced to 95% of it's value. In other words - if I set the maximum size to 100G and the water mark to 90% then, assuming the maximum life limit hasn't been hit, then, once 100G has been exceed, files will be removed until the total size is no more than 90G. Similarly, if I choose to keep data for 10 days, once the cache directory has >10 days of files, it will be removed down to 9 days of files there. Is that right? - Bob -- Bob Franklin [email protected] / (+44 1223 7) 48479 Networks, University Information Services, University of Cambridge ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
