Unable to create partitionable Raid1
Posted: 2011/08/16 20:20:25
Hello,
I previously was able to install CentOS 5 on a partitionable raid1 following this instruction:http://wiki.centos.org/HowTos/Install_On_Partitionable_RAID1.
Recently, I just installed a CentOS 6 on a new system, and was trying to follow the same instruction, but was stuck at step 5. When I tried to mount the array using:
bash-4.1# mount /dev/md_d0p1 /mnt/sysimage
mount: you must specify the filesystem type
Earlier in the process, when I was creating the raid, mdadm was complaining that a partition table already existed on /dev/sda:
bash-4.1# mdadm --create --level=1 --raid-devices=2 /dev/md_d0 /dev/sda missing
mdadm: partition table exists on /dev/sda but will be lost or meangless after creating array
mdadm: Note: this array ahs metadata ath the start and may not be suitable as a boot device. If you plan to store '/boot' on this device please ensure that your boot-loader understand md/v1.x metadata, or use --metadata=0.98
Continue creating array? y
mdadm: Defaulting to version 1.2 metadata
mdadm: array /dev/md_d0 started
bash-4.1#
I don't know if these two are related.
Any help is appreciated!!
