Possible to change chunk size on RAID-1 without re-init or destructive result?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Greetings,

I have a RAID-1, two disk volume that was created with a strange chunk
size. For reasons I won't go into here removing the data and
redefining a new RAID-1 volume with a different chunk size is
presently not a viable option.

Since this is a two disk mirror I should, /*theoretically*/ be able to
redefine the chunk size without impacting existing data. I have never
attempted such a thing and am not sure how best to go about it. I know
in a striped data level like RAID-5 or RAID-6 this would absolutely
not be possible.

I know I would have to set a different chunk size in the superblock.
Google and wiki research do not show a clear method to do this.

Any suggestions are appreciated.
