I suppose it's ext3 for now. 1) If there's space on the VG debian, just extend the root LV : To see space used on the debian VG : # vgs debian Add space to root : # lvextend -L+50M /dev/vg/debian/root Extend the filesystem # resize2fs /dev/vg/debian/root 2) You've got space on /var, so reduce it to give space to root : # resize2fs /dev/debian/var 2G # lvextend -L 350M /dev/debian/root # resize2fs /dev/debian/root If you use reiserfs instead of ext3, replace resize2fs by resize_reiserfs (see man for the parameters). If you use xfs, you cannot shrink, but can grow with xfs_grow If you use jfs, I don't know, but there's certainly a command at least to grow the filesystem. Note : ext3 can be resize online since <put her a kernel version> and by default if the filesystem has been created with e2fsprogs >= 1.38+1.39-WIP-2006.03.29-1 (mke2fs -O resize_inode is by default)
