I have a raid-1 array with 2 disks, each disk has been replaced with a larger one and now I want to enlarge the array to use the new space, however the software does not allow me to enlarge the array.
The pictures:
1: Here we see the manual instructions (MLD) how to migrate(expand capacity) an array.
2: Type of machine and array
3: Latest raid manager software installed and the problem in view, I can’t select the new space to be added to the existing array.
Now the software is telling me it is a raid-0 while it is clearly a raid-1.
Questions;
1. Is this a bug in the software where it is seeing a raid-1 as a raid-0 and (obviously) not allowing it to be expanded
2. Or do you have to read the manual differently, ea. To expand an array you need to expand it to added disks, you cannot expand on the same disk
If 1, how do I proceed to get this bug listed and solved ?
If 2 then I need to put the old disks back and add the new disks in new slots, then expand the raid-1 from the old disks to the new disks, is this the correct procedure ?
Additionally, I did search the forums and found that I might need to go route 2, however it also mentions that this might take weeks, so what about creating a new raid-1 on the new disks and somehow transfer the raid-1 from old disks to new disks ? any ideas which software to use for that ? clonezilla liveCD ? Or could I use a windows software raid-1 between the arrays and then break off the old array when done, then re-size inside windows, would that work ? Obviously looking for a live solution, not really time to do this offline.
