Subject: interaction with hardware RAID?
Date: Wed, 22 Aug 2012 13:05:49 +0200 [thread overview]
Message-ID: <5034BD0D.8050706@pocock.com.au> (raw)
It is well documented that btrfs data recovery (after silent corruption)
is dependent on the use of btrfs's own RAID1.
However, I'm curious about whether any hardware RAID vendors are
contemplating ways to integrate more closely with btrfs, for example,
such that when btrfs detects a bad checksum, it would be able to ask the
hardware RAID controller to return all alternate copies of the block.
Is this technically possible within any hardware RAID device today, even
though not implemented in btrfs?
Has there been any suggestion that vendors would support this in future,
presumably for the benefit of btrfs, ZFS and other checksumming filesystems?
