Bad news for LMG servers using Btrfs

Here is some bad news about Btrfs and their raid code for types 5/6. Unfortunately, this is what I believe Linus and his team use on all of their unRAID servers. It also makes me question whether or not this could have been the reason for their catastrophic data loss from before.

 

I really think they would have been better off with a file system more time hardened like ext4, but it's their call.

 

EDIT* I guess unRAID does not use RAID5/6 with their system, so this shouldn't affect LMG after all

Its not what they use. The use the file parity in unraid. They tested a server with raid 5 once.

Oh, well that's good to know. I was worried.

And that shouldn't be a big problem anyways as there are backups(preferably on tape)
