I'm about to start my conversion process (RFS to XFS).
I thought 6.4 would bring some tool to help with the subject, but that isn't the case
I have a 4TB empty disk currently being precleared.
I will go for the "Share based, no inclusions, preserving parity" method
- Move all data from a source rfs disk to the empty xfs disk
- Once the source rfs disk is empty, format it with xfs
- It becomes the new empty xfs disk
- Repeat from the top
Data will exist in a different disk, but I won't need to swap disks around.
I'll monitor how long it takes. If it's unbearably long ( (I expect it to be, as experienced by Harro), I'll probably test migrating one disk with the "Share based, no inclusions, no parity", to feel the difference in data transfer times. If it makes sense, I'll consider moving forward with the no parity dreaded feeling
