From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ram Ramesh Subject: Is it safe to shutdown while mdadm --grow is in progress. Date: Sun, 12 Oct 2014 00:46:14 -0500 Message-ID: <543A15A6.5010508@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Return-path: Sender: linux-raid-owner@vger.kernel.org To: Linux Raid List-Id: linux-raid.ids I googled this topic and got differing answers. Some old ones report horror stories and others suggest rebuild continues after reboot normally. My array is rebuilding and it will take about 6 days to complete. I am expecting bad weather in a couple of days and would like to proactively shutdown the machine and reboot. Is this safe? If the information is already available in a clear manner, please let me know. uname: Linux xxx 3.13.0-37-generic #64-Ubuntu SMP Mon Sep 22 21:28:38 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux mdadm - v3.2.5 - 18th May 2012 Thanks for your help Ramesh
