Yes, I just did it on a VM to test. I booted from a LIVE image so the nothing was mounted.

So, I ran lvresize with -L to increase the swap LV ran mkswap to remake the swap partition AFTER [root@f30g ~]# lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert root fedora_f30g -wi-ao---- 16.00g swap fedora_f30g -wi-ao---- 2.80g -- The key to getting good answers is to ask good questions. _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org 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@lists.fedoraproject.org
