<p class=MsoNormal>Hello all.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I recently migrated a logical volume from a failing host to
a new host, and although I am able to mount and access the volume, I cannot
view any of the LV information using lvdisplay, vgdisplay, or pvdisplay.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The physical volume is SAN mounted. The
/etc/lvm/backup/file was copied from the failing host to the new host, and
using vgcfgrestore and vgchange, the LV’s are now mounted on the new host
and completely accessible. However, when I run any of the display or scan
commands, information regarding these volumes does not appear. I’m
wondering if I missed a step in recovery. Following are the steps I
followed:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>-on source host, unmounted the file system using the LV in
question<o:p></o:p></p>
<p class=MsoNormal>-presented LUN the LV is on to the new host, and discovered<o:p></o:p></p>
<p class=MsoNormal>-coped /etc/lvm/backup/file from source to target<o:p></o:p></p>
<p class=MsoNormal>-on target host, vgcfgrestore on the copied backup file<o:p></o:p></p>
<p class=MsoNormal>-on target host, lvscan. The LV was recognized, but
not active.<o:p></o:p></p>
<p class=MsoNormal>-vgchange to activate the LV<o:p></o:p></p>
<p class=MsoNormal>-another lvscan showed the LV active<o:p></o:p></p>
<p class=MsoNormal>-modifed target host:/etc/fstab <o:p></o:p></p>
<p class=MsoNormal>-mounted the LV on the target host without issue. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Is there another step or two (or more) that I should have
executed prior to mounting or even recovering the LV?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any and all assistance is greatly appreciated.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks<o:p></o:p></p>
