QuestionRecovering RAID5 md device from foreign OS Pin
Member 1497193821-Oct-20 15:56
MemberMember 1497193821-Oct-20 15:56 
I have a single USB drive (RAID5 partitioned ) which was build using mdadm in another OS.

I can identify it using blkid

/dev/sdk1: UUID="fbe4babd-b3c2-8449-66d4-881d46391ff4" UUID_SUB="3f38abb1-3b6a-6663-0829-4241ab1355a6" LABEL="a-SATA:42" TYPE="linux_raid_member" PARTLABEL="MD42_1" PARTUUID="544f03a0-ffff-4255-b0a9-4ff76dbb09b9"
/dev/sdk2: UUID="fbe4babd-b3c2-8449-66d4-881d46391ff4" UUID_SUB="e6552375-0dba-dd6b-1d13-46d885edfff9" LABEL="a-SATA:42" TYPE="linux_raid_member" PARTUUID="5b73b607-39f2-40ca-a028-e599dc5f3756"
/dev/sdk3: UUID="fbe4babd-b3c2-8449-66d4-881d46391ff4" UUID_SUB="bf6527e4-f485-b485-e9a3-eab63fd4c21e" LABEL="a-SATA:42" TYPE="linux_raid_member" PARTUUID="c1fa94cf-572b-47e5-bff4-15122407ff85"
/dev/sdk4: UUID="fbe4babd-b3c2-8449-66d4-881d46391ff4" UUID_SUB="1bbf32d5-eb1b-2805-0057-27bddff7e27f" LABEL="a-SATA:42" TYPE="linux_raid_member" PARTUUID="553743fe-880c-4618-91cb-14692e939062"
/dev/sdk5: UUID="e024cedd-e0e9-4f44-806a-567129fe1a8a" TYPE="ext4" PARTUUID="f94d16e0-d7e0-4ac9-852d-3ef820e523c8"


My current OS gparted obviously does not see md device associated with the array, but it sees the USB /dev/sdx (and all the partitions) , and it does not exist in mdadm.conf file. Also mdadm --detail --scan --verbose cannot see it either - no surprise here.

Is there a SAFE way to recreate RAID5 md device in my current OS?

Can I use mdadm --create ..... to keep current data intact?
