RAID 6 stable?

RAID 6 stable?

[Hans Kraus]

Hi,

after a posting in the linux-btrfs mailing list I stumbled across
<https://btrfs.wiki.kernel.org/index.php/Project_ideas#Raid5.2F6>.

Does that mean that BTRFS RAID6 is free of known errors and ready for
deployment on data servers?

If not: is there an estimation (time-wise) when RAID6 is ready?

The background of my question: I have to rebuild my samba server which
ran out of storage. I'm using currently efs4 on top of mdadm RAID6.
I would prefer to rebuild it with BTRFS. I can postpone that rebuild
for some months.

A second question: the ZFS docu recommends very strongly to use ECC
memory on machines with ZFS RAID-Zn. Holds these arguments true for
BTRFS as well?

Kind regards,
Hans

This is simply true. For any use case. It is always better to have ECC
memory than memory without ECC.
