NAME
lvmadm - display limits associated with a volume group version
SYNOPSIS
/usr/sbin/lvmadm
{-t|-l}[-V vg_vers ][
-F]
/usr/sbin/lvmadm -m
DESCRIPTION
The lvmadm command is used to perform the actions below:
• Display the limits associated with a volume group version.
• Display the LVM configuration that is contained in the
/etc/lvmtab and /etc/lvmtab_p
files for
the indicated volume group version.
• Update the
/etc/lvmtab or /etc/lvmtab_p
entries of the bootable volume group and the boot
information present in the boot disk either during or after boot.
With the boot disk’s physical location changing prior to reboot or when the system is booted with a
cloned disk, the
/etc/lvmtab or /etc/lvmtab_p
entries of the bootable volume group and the
boot information present in the boot disk may be out of sync with the kernel. In such a situation, fol-
lowing root volume group activation (either during boot or post boot) use the
lvmadm command in
migrate mode (-m option) to update the information present in the /etc/lvmtab or
/etc/lvmtab_p files and the boot information present in the boot disk with the kernel. See lvm (7)
for more details.
