No. As far as I know you can run vgscan without unmounting your filesystems.

Hi:

The direct answer to your question is "no". However, you should read carefully the "warning" section of the man pages for 'vgscan'. Pay attention to alternate links and boot information.

No. Make a copy of /etc/lvmtab before doing it though, just in case you want to go back or look at the previous LVM config file.

It is not must, you can do it without umount. However, if /etc/lvmtab is destroyed, donot use vgscan to re-construct /etc/lvmtab if the system is heavily loaded by an application.

Hi,

No you do not need unmount the filesystem, but if i were you, keep a back up of the existing /etc/lvmtab, Also run vgscan -v -p (in preview mode) (to check everything is ok)before recreating the lvmtab file.
