Seems like cryptosetup has a resize options so for me lvresize partition cryptosetup resize partition While a backup is recommended in these cases, I haven't taken one yet when resizing lvs or reiserfs filesystems. That doesn't stop me from recommending you take a backup. IIRC, your setup is: Disk(s) - LVM - LVs - LUKS - crypto (block) devices - ext2/3/4 - filesystem After you've told LVM to grow the LV (lvresize) and LUKS to grow the crypto device (cyptosetup resize) you'll probably need to tell ext2/3/4 to grow the filesystem (resize2fs [offline][1]). [1] IIRC, there's a utility to do growing while the filesystem is mounted, like I do for reiserfs. -- Boyd Stephen Smith Jr. ,= ,-_-. =. b...@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/\_/ signature.asc Description: This is a digitally signed message part.
