- amalag 14y agoIs ZFS stable enough on FreeBSD? Seems to be an unofficial port.
- Dobbs 14y agoZFS is very stable on recent versions of FreeBSD, I can't speak for older versions as I don't have experience. I at least haven't had any issues with it and we use it in production. It is an older version and not as feature complete as what you will find in Solaris.
- duaneb 14y agoZFS is very stable on FreeBSD.
- awaythrow 14y agoBut you need a lot of extra RAM compared to the usual filesystems. Is that correct? If yes, is using ZFS worth the cost of the extra RAM?
- cdawzrd 14y agoZFS doesn't use that much RAM if you don't turn on deduplication, which is of less use in a system that serves large compressed video files than one that handles tons of read/write traffic as an office file server.
- gauravk92 14y agoYou don't need the extra ram. ZFS uses it as a cache, more ram, more cache. That's about it, otherwise it doesn't use much ram.
- duaneb 14y agoRAM is not required; it just makes lookup faster with caching.
- wanderr 14y agoWhy would they use ZFS on a CDN? IIRC, ZFS has some performance characteristics that would make it a poor choice for something like caching data on a network edge when it's really designed for ensuring data integrity.
