Subject: cannot attach backing device, wipefs does not fix it
Date: Wed, 18 Jun 2014 15:38:55 +0000 (UTC)	[thread overview]
Message-ID: <loom.20140618T173307-560@post.gmane.org> (raw)

Hi, ubuntu 14.04, and a 5TB RAID (sdc) partitioned into two 2.5TB partitions
(sdc1 and sdc2) with parted to be used as backing devices, 

/dev/sdc2 attaches fine

problem with sdc1:

# make-bcache -B /dev/sdc1
Device /dev/sdc1 already has a non-bcache superblock, remove it using wipefs
and wipefs -a

# wipefs /dev/sdc1
wipefs: WARNING: /dev/sdc1: appears to contain 'dos' partition table

# wipefs -a /dev/sdc1
wipefs: WARNING: /dev/sdc1: appears to contain 'dos' partition table

# make-bcache -B /dev/sdc1
Device /dev/sdc1 already has a non-bcache superblock, remove it using wipefs
and wipefs -a

In other words, Im unable to attach sdc1

any help greatly appreciated!

/Erik
