too many metadata areas for pvresize

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.

  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 !!
