Countdown to ONE BILLION FILES!
I was reading Ric Wheelers "One Billion Files: Scalability Limits in Linux Filesystems" . As a ZFS user, I was wondering how many files we store on one of our mail storage systems in a single zpool. My colleague was so kind to start a find on the system. Four days later we got # find /export -type f | wc -l 811874848 Interesting. We are already close to one billion files in production . Next step was to look at the average file size. Currently, 12.5TB are referenced, compression ratio is 1.77x. This results in a average size of ~30kB. How long will it take to reach one billion files? In average, 60 mails get delivered per second to the storage system (over NFSv4!). Therefore, to get the missing 190 million files, we only need to wait a little bit more than a month.
