Hi,

By accident I have created an array with simple quotes in name:

mdadm --assemble /dev/md0 --name=\'newname\':0 --update=name /dev/sdb1 
/dev/sdd1

My mdadm.conf contains following line:

ARRAY /dev/md/0 metadata=1.2 UUID=0324aa8b:e17efd1a:bae27dd0:66fc7573 
name='newname':0

Mdadm fails to assemble this array. After removing the name from 
mdadm.conf, everything works fine.

mdadm  --assemble --scan -v 2>&1 | grep sd[bd]1
mdadm: no RAID superblock on /dev/sdd1
mdadm: no RAID superblock on /dev/sdb1
mdadm: /dev/sdd1 has wrong uuid.
mdadm: /dev/sdb1 has wrong uuid.
mdadm: /dev/sdd1 has wrong name.
mdadm: /dev/sdb1 has wrong name.

I'm using mdadm - v3.2.5 - 18th May 2012 and kernel version 3.4.35. The 
superblock contains:

mdadm  --examine /dev/sdb1
