Re: Moving mdadm raid volume to new OS install
Hi Pascal,
I'm not sure what top-posting is?
I hope this isn't it!
You mean test whether i can bring the raid vol up by booting into 64bit debian from usb?
i did a mdadm -e on one of the disks in the array
root@HTPC-NAS:~# mdadm -E /dev/sdc1
/dev/sdc1:
Magic : a92b4efc
Version : 1.2
Feature Map : 0x0
Array UUID : 25a729b1:71f5193b:6abe8ba9:21e698f5
Name : HTPC-NAS:0 (local to host HTPC-NAS)
Creation Time : Thu Dec 20 12:25:56 2012
Raid Level : raid1
Raid Devices : 2
Avail Dev Size : 5860268032 (2794.39 GiB 3000.46 GB)

Used Dev Size : 5860267648 (2794.39 GiB 3000.46 GB)
Data Offset : 262144 sectors
Super Offset : 8 sectors
State : clean
Device UUID : fe1998ea:8535a654:31083985:d8c560c1
Update Time : Thu Feb 7 09:01:38 2013
Checksum : ad4320a8 - correct
Events : 51
Device Role : Active device 1
Array State : AA ('A' == active, '.' == missing)
I think the 1.2 means it's a no go in terms of running the disk independently of the raid vol.
Thanks
Sam
