I have an Acer EasyStore with a RAID5 mdraid array I use for storing my home files (photos, movies, etc), and I want to migrate it to ZFS with Ubuntu (the native kernel module from zfsonlinux.org).
I hear that ZFS needs a lot of RAM, but the EasyStore only has 2 GB. The RAIDZ will be three 1.5GB disks, and I'm wondering if ZFS won't work with 2 GB of RAM. What problems, if any, am I likely to see? Performance isn't a concern, as long as it can stream HD movies in real time, which is basically the use case this computer sees.
