Say we need to grew metadata size to 2048k:
* vgcfgbackup -v -f /path/to/file <vg_name> * stop nfs server * umount all LVs * lvchange -an all LVs * vgchange -an <vg_name> * pvdisplay and note UUID and /dev/path * pvcreate -ff --metadatasize 2048k [--metadatacopies 2] --uuid <UUID here> /dev/path * vgcfgrestore -f /path/to/file -v <vg_name> * pvs -o +pv_mda_free - just to check * vgchange -ay * lvchange -ay all LVs * mount -a <vg_name> * start nfs server
