#Unraid setup install

Test: Laying out IO file (1 file / 32768MiB) fio -direct=1 -name=test -bs=256k -filename=/mnt/dumpster/test/whatever.tmp -thread -size=32G -iodepth=64 -readwrite=randrw sync=1 will force synchronous writes, which is the type of thing you encounter when this zfs dataset (path) is doing something like hosting a database and in some virtual machine workloads. You вЂњkind ofвЂќ want the testing to be larger than the ram you have to get a sense of how the performance of the disk subsystem is. On any spinning rust thatвЂ™s likely to take a while. The above command will do an fio test with a 256k block test writing 32 gigabytes. Then you can use fio fio -direct=1 -name=test -bs=256k -filename=/mnt/dumpster/test/whatever.tmp -thread -size=32G -iodepth=64 -readwrite=randrw ( -sync=1 ) zfs create dumpster/test -o casesensitivity=insensitive -o compression=off -o atime=off -o sync=standard^C fio-3.7-x86_64-1_slonly.txzДЇirst create a zfs dataset that lacks compression and atime (compression can skew results especially if the file is highly compressible). I stumbled through installing fio manually by guessing it may be slack 14.2 and downloading this: Unraid seems to be based on slackware, but lsb_release and the usual handy stuff for figuring out what version of slackware seemed to be missing. To verify that my tiny 4 disk raidz1 setup had been created correctly. I used zpool create dumpster raidz /dev/sdb /dev/sdc /dev/sdd /dev/sde I had sd available to create a new zpool. This will help you identify block devices on your system. Experiment, though, and report your results here for the benefit of everyone? There have been cases in the past where that mechanism was not good at sharing memory with other processes, but by and large you may not need that. Whether or not this is a bad thing is probably on the side of not really a bad thing if it uses all your ram as it will give up ram if the ram becomes short. Otherwise the arc filesystem cache will happily use all your ram. The plugin documentation has a handy hint about limiting the arc cache size which is great for mixed-use boxes. Plugins on unraid involve pasting links into unraid, so thatвЂ™s neat.

#Unraid setup install

What is this? This plugin is a build of ZFS on Linux for unRAID 6 Installation of the plugin To install you copy the URL below into the install plugin page in your unRAID 6 web gui or install through the Community Applications.

Here is the info for the ZFS on unraid plugin: YouвЂ™ll need at least 1 or 2 other storage devices to create an вЂњUnraid ArrayвЂќ so that the Plugins/Docker/VMs tab will work in Unraid (bummer). I didnвЂ™t see a clean way to use only a ZFS pool either. ItвЂ™s a life-in-your-own-hands scenario using the system off-script like this.

ZFS support on Unraid is not supported by Lime Tech or, well, anyone. Things can go wrong and your data can get trashed. It seems to have a diverse and talented user base and the user base is adding a lot of features and flexibility to the system. The last few weeks have been the first time IвЂ™ve used Unraid in some time and it has matured well. And I did a lot of failure mode testing to go with these videos, but it held up surprisngly well so maybe those videos arenвЂ™t super interesting. It has great performance вЂ“ very nearly at parity with FreeBSD (and therefor FreeNAS ) in most scenarios вЂ“ and itвЂ™s the one true filesystem. ZFS on Linux is great, and finally mostly mature.
