How to use the maximum VDO logical blocks without overcommiting?
I would like to utilize the max space for logical blocks without overcommiting the the physical blocks available. As I know there are metadata used by VDO.
Sometimes we may expand the VDO backend storage.
So it may be difficult to adjust the corresponding VDO logical blocks.
Say I have this information:
vdo status | grep blocks
1K-blocks: 10170368 1K-blocks available: 3295368 1K-blocks used: 6875000 compressed blocks written: 111 data blocks used: 937367 journal blocks batching: 0 journal blocks committed: 553 journal blocks started: 553 journal blocks writing: 0 journal blocks written: 553 logical blocks: 1434421 logical blocks used: 1277082 overhead blocks used: 781383 physical blocks: 2542592 reference blocks written: 8 slab journal blocks written: 8 slab summary blocks written: 18
I would like to have an option to expand the maximum logical blocks without overcomiitting, just like lvm command similar to '-L 100%FREE.' Instead of manual calculation.
