root@daemon:~ # freebsd-update -r 13.0-CURRENT upgradeYou need a recent 12-STABLE or 13-CURRENT. It will not work on 12.0-RELEASE as it is missing required kernel features.
thanks very much, i will have a try, this will be very interestingThe instructions to use -SATBLE are :
- for tracking -STABLE : https://www.freebsd.org/doc/handbook/current-stable.html#stable
- for building world and kernel : https://www.freebsd.org/doc/handbook/makeworld.html
To be honest, for building world and kernel, I use a simplified version detailed here : http://www.wonkity.com/~wblock/docs/html/buildworld.html . It has never failed me so far.
Looks like somebody published the OpenZFS Kernel module: sysutils/openzfs-kmod. So in theory we can do full disk encryption with ZFS native encryption too. At least I hope so. I'll try it out.
Are you sure that it is only the encryption that slows it down? I'll give it a try too, but I am working on something else now. It has to wait a few days.I am currently doing loads of benchmarks, the tests are by far not finished and I will publish the results as soon as I have managed to go through all the data and prepare a nice article. However, to grab a random result from my completed tests: FreeBSD geli (blocksize 4096, aes-xts with keysize 128) + native ZFS with ashift=12: READ: 72.2MiB/s, WRITE: 18.1MiB/s from a random-read-write test with 80% read requests, on a 4core AMD machine with 8GB RAM + SSD. Same machine, same test, but with openzfs-kmod, encrypted with aes-128-ccm, ashift=12, gets only 6324KiB/s READ and 1585KiB/s WRITE.
