Sooner or later you will trash your data unless you're using ECC memory (which the Raspberry Pi RAM chips are not): http://louwrentius.com/please-use-zfs-with-ecc-memory.html http://louwrentius.com/please-use-zfs-with-ecc-memory.html
For the record, I also think it's cool to get this compiled and running on RasPi; just wanted to add the ECC info for anyone now thinking of doing something with this in production :-D.
- jlgaddis 11y agoZFS without ECC is no worse than any other file system which doesn't do checksumming.
- lorenzfx 11y agoSee a quote from Matt(hew) Ahrens (zfs developer)[0]: There's nothing special about ZFS that requires/encourages the use of ECC RAM more so than any other filesystem. [...] I would simply say: if you love your data, use ECC RAM. Additionally, use a filesystem that checksums your data, such as ZFS.
