Как взять место из одной ВГ и добавить в другую?

Я видел, что /dev/mapper/VGP4--CHK-LVP4--CHK не хватает места. Я хотел бы увеличить это.

Я хотел посмотреть, смогу ли я расширить VG, купив «заимствование» места у другого VG. Я запустил pvs:

PV         VG         Fmt  Attr PSize    PFree
  /dev/sda1  VGroot     lvm2 a--   100.00g       0
  /dev/sdb1  VGvar      lvm2 a--   150.00g       0
  /dev/sdc1  VGP4-depot lvm2 a--     2.00t       0
  /dev/sdd1  VGP4-depot lvm2 a--     2.00t  102.39g
  /dev/sde1  VGP4-CHK   lvm2 a--    50.00g       0
  /dev/sdf1  VGP4-meta  lvm2 a--  1024.00g       0
  /dev/sdg1  VGP4-JNL   lvm2 a--   200.00g       0
  /dev/sdh1  VGswap     lvm2 a--    65.00g       0
  /dev/sdi1  VGP4-CHK   lvm2 a--    51.00g 1020.00m

Как мне взять 100 ГБ из /dev/sdd1 VGP4-depot, чтобы увеличить мою другую виртуальную группу, которая заполнена на 97% и не хватает места?

Кроме того, правильно ли поступать так, когда в группе заканчивается место для хранения — следует ли брать данные из других групп?
