(2.6.20.4) Date: Tue, 27 Mar 2007 05:59:34 -0400 (EDT) Message-ID: Mime-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII; format=flowed Return-path: Sender: linux-raid-owner@vger.kernel.org To: linux-kernel@vger.kernel.org Cc: linux-raid@vger.kernel.org List-Id: linux-raid.ids I ran a check on my SW RAID devices this morning. However, when I did so, I had a few lftp sessions open pulling files. After I executed the check, the lftp processes entered 'D' state and I could do 'nothing' in the process until the check finished. Is this normal? Should a check block all I/O to the device and put the processes writing to a particular device in 'D' state until it is finished? Justin.
