Need help with raid 1 array on 3TB disks Mint 13/(Ubuntu12.10)
I have looked all over for an answer to this.
I created a RAID1 array on two non OS 3TB GPT disks using mdadm, it built, formatted EXT3, shows up in "Computer" as raidarray: DATA. Won't open. I have also tried sudo mdadm --detail --scan >> /etc/mdadm/mdadm.conf which returns: bash: /etc/mdadm/mdadm.conf: Permission denied When I type sudo mdadm --assemble md127p1 I get sudo mdadm --assemble md127p1 sudo: unable to resolve host CHUX-OFFICE mdadm: Unknown keyword automatically mdadm: Unknown keyword devices=/dev/sda,/dev/sdc mdadm: md127p1 not identified in config file. Here is my config file: # mdadm.conf # # Please refer to mdadm.conf(5) for information about this file. # # by default (built-in), scan all partitions (/proc/partitions) and all # containers for MD superblocks. alternatively, specify devices to scan, using # wildcards if desired. DEVICE partitions containers # auto-create devices with Debian standard permissions CREATE owner=root group=disk mode=0660 auto=yes automatically tag new arrays as belonging to the local system HOMEHOST <system> # instruct the monitoring daemon where to send mail alerts MAILADDR root # definitions of existing MD arrays devices=/dev/sda,/dev/sdc # This file was auto-generated on Wed, 05 Dec 2012 14:34:04 -0500 # by mkconf $Id$ ARRAY /dev/md/CHUX-OFFICE:raidarray metadata=1.2 name=CHUX-OFFICE:raidarray UUID=e914546a:acda8d4c:18876044:5d3291b5 I'm missing something. Just don't know what I don't know. When I typesudo mdadm --detail --scan >> /etc/mdadm.conf I get bash: /etc/mdadm.conf: Permission denied When I type (in terminal) mount /dev/md127 I get: mount: can't find /dev/md127 in /etc/fstab or /etc/mtab Here is the output of blkid: /dev/sda: UUID="e914546a-acda-8d4c-1887-60445d3291b5" UUID_SUB="09db3d27-f028-d46e-2c4f-e5b9b33e9ac8" LABEL="CHUX-OFFICE:raidarray" TYPE="linux_raid_member" /dev/sdb1: UUID="b0356e31-e000-4e2b-8686-692f4903ac75" SEC_TYPE="ext2" TYPE="ext3" /dev/sdb2: TYPE="swap" /dev/sdb3: LABEL="data" UUID="758b15ec-6cbe-4e66-ace9-4b21275987c6" TYPE="ext3" /dev/sdb4: LABEL="home" UUID="eae4f52b-4871-4285-8abd-dbf46da85eaa" SEC_TYPE="ext2" TYPE="ext3" /dev/sdc: UUID="e914546a-acda-8d4c-1887-60445d3291b5" UUID_SUB="341a001c-d676-b582-722a-12243a52ff87" LABEL="CHUX-OFFICE:raidarray" TYPE="linux_raid_member" Here is my fstab file: # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.
