lvm2 should not allow reducing thin metadata LV
Last modified: 2015-12-15 05:45:46 EST
Description of problem:
Able to shrink a thin pool metadata LV causes kernel
to complain about the reduced size.
Version-Release number of selected component (if applicable):
kernel 4.2.3-200.fc22 and upstream 4.3.0
Steps to Reproduce:
1. create thin_pool
2. grow thin pool metadata LV
3. shrink "
Kernel complains about metadata device being too small
lvm2 should prevent reducing pool metadata LV
untill dm-thin gets enhanced to cope with it.
Resolved with upstream release of lvm2 2.02.129
This is already fixed in Fedora 23 release (where we have lvm2 > 2.02.129).
