Subject: question about raid10 near copy info in man mdadm.
Date: Mon, 16 Apr 2012 13:28:14 +0800 [thread overview]
Message-ID: <201204161328097657740@gmail.com> (raw)
Hi:
I readed the information about raid10 near copy in man mdadm.
It is:
'n' signals 'near' copies. Multiple copies of one data block are at similar offsets in different
devices.
But I think this wrong.
If raid10 had five disks and near copy is equal three.
The layout like:
5 disks
--------------------
A1 A1 A1 A2 A2
A2 A3 A3 A3 A4
But the copies of datablock A2 are not at similar offset in different device.
