Уменьшить основной зашифрованный раздел

[Indeoo]

Есть  SSD 500G
Установлен только 1 раздел на все пространство (не считая /boot)
Диск зашифрованный во время установки стадартными тулзами ubuntu.

Можно ли уменьшить размер этого раздела? Если да, то подскажите тулзу/статью
Ubuntu 20.04LTS

[F12]

LVM ?

[F12]

данные, представляющее для тебя ценность, на ПК хранятся ?

[Indeoo]

Да, но могу сделать бекап на флешку.

[F12]

Бекап лишним никогда не бывает!

В LVM есть возможность достаточно легко и оперативно, практически на лету, как увеличивать, так и уменьшать размер раздела. Мануалов о том как и в какой последовательности это делать, в Интернете предостаточно, просто погугли на тему "изменить размер LVM в Ubuntu 20.04"

Так что делай бекап данных, и пробуй... помолясь...

НО СНАЧАЛА ОБЯЗАТЕЛЬНО БЕКАП!!!
