RFE: Disk space usage by a LVM snapshot
Last modified: 2016-04-08 02:08:26 EDT
Description of problem:
Enhance thin tools support to calculate actual disk usage of thin logical volumes and LVM Snapshots created from a thin logical volume.
The actual disk usage of each lvm snapshot and lvm thin volume.
If possible the capability to ask for the size based on thin id/name of the snapshot or thin logical volume.
In case you're requesting the metadata footage, see tool thin_metadata_size
The bug here tries to learn the 'space' occupied by individual LV.
It has some 'shared' mapppings
And some 'exlusive' mappings.
Initially we should provide some 'script' to calc these 2 values.
Later those could be built-in into e.g. thin_dump tool.
Let's think about how lvm2 could make it easier for user.
Could you please let me know if there are any plans for this RFE.

The latest device-mapper-persistent-data package should include the new 'thin_ls' utility. But I'll defer to Joe and/or Peter to say definitively.
Yes, we have thin_ls in device-mapper-persistent-data package since device-mapper-persistent-data-0.6.0-1 (20th January).
But still, we're planning to display this info in LVM command directly (this is RFE for lvm2).
