| 与lvol或rvol等逻辑卷文件类似,group文件是整个VG的设备文件,系统用此文件来管理VG。 在做 vgscan 时, group 文件会被用来做match, For detail look for the manual of 'vgscan','vgimport','vgexport' It groups these physical volumes into volume groups by matching the volume group information found on the physical volumes. Then it searches the /dev directory for all group device files with the LVM major number, and tries to match device files with the logical volumes' information found on the physical volumes. |
