too many metadata areas for pvresize[modifier]

This "too many metadata areas for pvresize" is telling you that pvresize doesn't know how to resize with metadata at the end of the device. Follow these steps as a workaround. These steps are potentially dangerous but have been tested and worked for me.

source => [1]

  1. vgcfgbackup -v -f /some/file volumeGroup
  2. vgchange -an volumeGroup
  3. pvcreate -ff --metadatacopies 1 --restorefile /some/file --uuid UUID /dev/device
  4. vgcfgrestore -v -f /some/file volumeGroup 
  5. pvresize /dev/device

Serrer les fessssssses !!
