Subject: [PATCH] Fix LVM2 PV shrinking with lvm2 2.02.171 and later (#1)
Shrinking an LVM2 Physical Volume on CentOS 7 with the latest
lvm2 2.02.177 fails like this:
Shrink /dev/sda9 from 1.00 GiB to 768.00 MiB
* calibrate /dev/sda9
* check file system on /dev/sda9 for errors and (if possib...(SUCCESS)
* shrink file system (ERROR)
* lvm pvresize -v --setphysicalvolumesize 786432K '/dev/...(ERROR)
0 physical volume(s) resized / 1 physical volume(s) not resized
Wiping internal VG cache
Wiping cache of LVM-capable devices
/dev/sda9: Requested size 712.00 MiB is less than real size 1.00 GiB. Proceed? [y/n]:[n]
Physical Volume /dev/sda9 not resized.
This upstream change to lvm2 [1] makes pvresize prompt for confirmation
whenever the --setphysicalvolumesize option is used. (The change was
included in lvm2 2.02.171 and later, which is used in recent
distributions. The reporter found the issue on Ubuntu 18.04 LTS and I
reproduced the issue on RHEL/CentOS 7.5). The set size option has to be
used when shrinking the PV before shrinking the partition therefore fix
this issue by adding lvm common option --yes when using the set size
option.

pvresize: Prompt when non-default size supplied.
Closes #1 - Can't shrink LVM partition due to pvresize prompt
