Last week I added a fourth disk to my RAID 5 setup using the guide on http://scotgate.org/2006/07/03/growi...5-array-mdadm/
Unfortunately, I forgot to update my /etc/mdadm.conf and rebooted like that.
Now, the raid set is identified as /dev/md127.
[root@mastodon ~]# mdadm --detail --scan --verbose
ARRAY /dev/md127 level=raid5 num-devices=4 metadata=0.90 UUID=d28897fc:8da6f8ef:bc01692b:1adecf8d
What should I do to make it appear as /dev/md0 again ? Can I simply modify /etc/mdadm.conf so it reads ARRAY /dev/md0.... or do I have to issue mdadm commands ?
[root@mastodon ~]# uname -a
Linux mastodon 220.127.116.11-43.fc11.i686.PAE #1 SMP Thu Aug 27 21:34:36 EDT 2009 i686 i686 i386 GNU/Linux
[root@mastodon ~]# mdadm --version
mdadm - v3.0-devel3 - 10th March 2009
I also should add that this is just a naming issue, I can mount /dev/md127 fine and I can reach my data.
Thanks in advance,
