Hello!
I do not know if I may receive any support about mdadm through this e-mail address. If not, please, could you forward this message to the appropriate box if one exists.
I am currently trying to migrate a Linux partition (Mandrake 10) to RAID 1. To this purpose I have installed mdadm V1.8.1.
This is an experimental version:
This is a "development" release of mdadm. It should *not* be considered stable and should be used primarily for testing. The current "stable" version is 1.8.0.
The first attempt was to configure an equally-sized partition of my second disk (/dev/hdb) as part of a degraded RAID 1 device. Unfortunately, starting the array fails. The following shows pieces of information that should help understanding the case:
The command I use is:
mdadm -C /dev/md0 --metadata=1 --level=raid1 --raid-devices=2 missing /dev/hdb5 -v
To which mdadm answers: mdadm: /dev/hdb5 appears to contain an ext2fs file system size=4843912K mtime=Thu Dec 2 17:11:54 2004 mdadm: /dev/hdb5 appears to be part of a raid array: level=1 devices=2 ctime=Sat Dec 4 18:28:46 2004 mdadm: size set to 4843904K Continue creating array? y VERS = 9000 mdadm: ADD_NEW_DISK for /dev/hdb5 failed: Invalid argument
_possibly_ because
Version 1 superblocks requires 2.6.10 or a recent 2.6.10-rc snapshot
Try agin with 1.8.0 and if you have probs then yell :)
