It has already been shown how the OP can accomplish what he wants after booting from a LIVE image. Anyway, if one tries to shrink a mounted filesystem they are presented with this.... [root@f32k2 ~]# lvresize -r -L -1G /dev/fedora_f32k2/home Do you want to unmount "/home" ? [Y|n] n fsadm: Cannot proceed with mounted filesystem "/home". /usr/sbin/fsadm failed: 1 Filesystem resize failed. And unmouting a filesystem that happens to be in use may result in "problems". -- The key to getting good answers is to ask good questions. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
