Hello.
I'd like to know if it is possible to upgrade the superblock model
version of an array, from 0.9 to 1.0 for example.
Theoretically it should be possible, I think. What would be the safe
steps to do it?
I imagine something like:
- zeroing the current superblocks in all the array disks;
- (optionally) assembling the array in "build" mode, ignoring superblocks;
- updating the superblocks using the desired version.
If that isn't possible, then:
- zeroing the current superblocks in all the array disks;
- creating a new array with those disks, using the desired superblock
version and --assume-clean;
- would this lead to the loss of the partition table inside the array?
Has anyone done such a thing?
How should I proceed?
Thanks,
Vasco.
