[linux-lvm] LVM2 not function

Hi,

 

I used LVM come with Redhat9 on my desktop computer.  Recent days I want to upgrade my kernel to 2.6.0-test11 which needs LVM2 to work with the device-mapper.  To be more up to date, I also recreated the lvs to use lvm2 metadata.  But when I rebooted the computer, new created lv can't mount.  It said it's not a valid block device.  So I check the status with "lvm lvscan", it showed that these lv turned to be inactive.  So I removed and recreated these lv.  Right after creation, these lvs were ACTIVE and mountable, but after reboot, they became inactive and unusable again.  Does anyone have clue?

Li Yang,

You should run "vgchange -ay" to active all the LVs.

Hi Leo Li,

Please run "vgscan -ay" as this command will activate
all the VGs and hence the LVs in your system.

Also, check if this command is present in your
/etc/rc.sysinit boot script, so that your VGs and LVs
are available for auto mount after reboot.

Regards,
Neerav

The correct sequence of commands is:

vgscan
vgchange -a y
