How Do I Update the Disk Metadata After the LVM Volume Is Remounted?

Scenarios

If the LVM volume is remounted when a BMS OS is reinstalled, you need to update the disk metadata in a timely manner. Otherwise, the OS will be unavailable after it is restarted.

Procedure

If a BMS uses LVM partitioning and the LVM volume is remounted when the BMS OS is reinstalled, update the disk metadata in a timely manner after the remount is complete. In this way, the disk metadata will be consistent with the disk mounting information after the OS is restarted. To update disk metadata, run the following commands (sysvg is the volume group (VG) name of the LVM volume):

lvm vgcfgrestore sysvg

lvm pvscan

lvm vgscan

lvm vgchange -ay
