vgchange
TLDR
Change the activation status of all volume groups
$ sudo vgchange -a y|n
Change the activation status of a specific volume group$ sudo vgchange -a y|n [volume_group]
SYNOPSIS
vgchange [options] [volumegroup_...]
DESCRIPTION
vgchange modifies the attributes of LVM volume groups. The most common use is activating or deactivating logical volumes within a volume group, which is necessary before the volumes can be mounted.
Volume group activation makes the logical volumes available to the system. Deactivation is required before physical volumes can be removed or the system can be safely shut down.
PARAMETERS
-a, --activate y|n|ay
Activate or deactivate logical volumes (y=yes, n=no, ay=auto-yes)-c, --clustered y|n
Change cluster attribute-x, --resizeable y|n
Change resizeable attribute--addtag _tag_
Add a tag to the volume group--deltag _tag_
Delete a tag from the volume group--refresh
Refresh metadata for active volume group-u, --uuid
Generate new UUID for the volume group
CAVEATS
Requires root privileges. Deactivating a volume group with mounted filesystems will fail. Use vgscan to discover volume groups. Part of the LVM2 package.
