Did I miss something along the way? > This should do the job then (I've tried this exact sequence on my machine): - deactivate the problematic LV: lvchange -an vg_data/lv_home - reduce the size of the LV by 1 extent: lvreduce -l -1 vg_data/lv_home - make the PV size to be in sync with the real device size: pvresize /dev/sdc1 - activate the LV: lvchange -ay vg_data/lv_home - run fsck for the FS on the LV: e2fsck -f -n /dev/vg_data/lv_home - resize the FS to be in sync with new LV size: fsadm resize /dev/vg/lvol0 - check the resized filesystem: e2fsck /dev/vg_data/lv_home Let me know if it works for you. -- Peter _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
