Comment 3 Nir Soffer 2016-10-20 17:13:42 UTC 
How to test:

1. Create 3 raw disks on block storage

Check the metadata slot mapping using:

$ lvs -o tags vgname | grep MD_
MD_4
MD_5
MD_6

2. Delete the disk using slot 6 (MD_6):

Verify that the MD_6 is not used:

$ lvs -o tags vgname | grep MD_
MD_4
MD_6

3. Create new disk

Verify that slot 6 is used by the new disk

$ lvs -o tags vgname | grep MD_
MD_4
MD_5
MD_6

Do we need to support more than 1948 lvs per vg?
Comment 11 Nir Soffer 2018-01-07 16:58:15 UTC 
Because of bug 1432039, we disable refreshes for the leases volume. If we want to
make the leases volume extendable, we need to add a mechanism for refreshing it
when trying to access a lease after the end of the device. Same way we do for
the metadata volume now.

Adding this bug as dependency.
