Hi Phil! Thanks for throwing in! Do you have the older default values? I suredon't. And how do you add offsets the the --create command? mdadm --create --assume-clean /dev/md1 --chunk=4096 --level=6--raid-devices=6 /dev/sdc1 /dev/sdd1 /dev/sdf1 /dev/sde1 missingmissing Is what I am working with now. Many thanks! This 8TB represents the last 8 years of my life on the net. Built thisRAID to protect that 'investment'. :'-( TIA Paul On Tue, Jan 3, 2012 at 5:26 PM, Phil Turmel <philip@xxxxxxxxxx> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Hi Paul, Roman, > > On 01/03/2012 04:37 AM, Roman Mamedov wrote: >> On Tue, 3 Jan 2012 10:41:04 +0400 >> Paul Richter <iamcomcy@xxxxxxxxx> wrote: >> >>> Researched the net as much as possible, added this to wiki page: >>> http://en.wikipedia.org/wiki/Mdadm#Recovering_from_a_loss_of_raid_superblock >> >> Oh, so it was you who originally wrote those instructions? :) >> See http://permalink.gmane.org/gmane.linux.raid/35538 > > I was going to cite myself ... > >> And also you probably mean http://en.wikipedia.org/w/index.php?title=Mdadm&oldid=468952888#Recovering_from_a_loss_of_raid_superblock >> because that part was nuked from the wikipedia page already. > > As to the original question: The odds are poor, but not zero.
