Hi Matthew,
i have to correct my last email: This works also with thinpool-lvs!
Better said: There was no error message executing this command. Will
walk on this way for more reults. Maybe the lvconvert-manpage is outdated?
Tfh!

Hi
I'm somehow missing the point here.
Could you please show us 'lvs -a -o+seg_pe_ranges'
Normally when you make a thin volume snapshot, the snapshot is sharing your
blocks within thin-pool. So no space is allocated on any SSD for this.
(And you cannot specify which block will be used in a thin-pool)
If you would be using 'old-snapshot' which does allocate 'extra' space for COW
block -then you would probably see horrible performance with 200 snapshots...
And finally - standard command for moving extents around in a VG is - 'pvmove'.

Zdenek
