Hi
I have a disk which two of the partitions are part of a RAID1 setup. I'm
trying to rename the the second raided partition
mdadm -E /dev/sdc4
/dev/sdc4:
Magic : a92b4efc
Version : 1.2
Feature Map : 0x1
Array UUID : 83d7657b:ebfddcb7:36b0fa14:d29a350c
Name : oldname:2
Creation Time : Tue Aug 30 15:25:10 2016
Raid Level : raid1
Raid Devices : 2
Avail Dev Size : 486696960 (232.08 GiB 249.19 GB)
Array Size : 243348480 (232.08 GiB 249.19 GB)
Data Offset : 262144 sectors
Super Offset : 8 sectors
Unused Space : before=262056 sectors, after=0 sectors
State : clean
Device UUID : 97aba979:dd4cf85c:f6dbf4f6:f1e9ccab
Internal Bitmap : 8 sectors from superblock
Update Time : Fri Sep 23 14:21:00 2016
Bad Block Log : 512 entries available at offset 72 sectors
Checksum : 749e26a8 - correct
Events : 7319
Device Role : Active device 0
Array State : A. ('A' == active, '.' == missing, 'R' == replacing)
For the first partition I stopped the RAID using
mdadm --stop /dev/md127
and then reassembeld using
mdadm --assemble /dev/md127 --name=newname_boot --update=name /dev/sdc2
The first partition was easy as the system had started the RAID, but the
second parition the system does start, and when I try to assemble it, it
tells me it's already active:-
mdadm --assemble --uuid=83d7657b:ebfddcb7:36b0fa14:d29a350c
--name=newname2 --update=name /dev/md2 /dev/sdc4
mdadm: Found some drive for an array that is already active:
/dev/md/oldname:2
So any ideas on how i can rename this ?
Thanks
Phil.
