Is it possible to change the Raid5 chunk size of an existing device?
- by AlexCombas
I have an existing raid5 device which I created using mdadm on Linux.
When I created the device I set the chunk size to 64 but I would like to test the performance of various sizes but I don't want to have to rebuild my entire system to do so.
If it is not possible to do it live then is it possible to do this by booting with a rescue disk?
Any advice on the steps how to do this, either live or with a rescue disk, will be greatly appreciated.
