Hmmmm, I've been contemplating btrfs on some new installs
with the eventual goal of a CEPH network file system, on top
of ext4 and/or btrfs. Is this issue just with the drivers, or
related to btrfs too?
How is btrfs , from the "driver's seat"?
Does this aberration you detail, extend to the Green Seagate 2T drives?
> I just saw on the mythtv list about the sector size problem these drives
Can you give a precise link to this list or can I follow it (read only)
via net news? (if so what is the news group name)?
I'd like to read up on this issue, as I have several gentoo installs
(very soon) that will have RAID1 using (2) ST 2T green drives.
Alternative RAID configs and performance/reliability results is
also of keen interest to many; so thanks for posting about these
issues.
James
