uuid</FONT> in LVM?</FONT></DIV>
<DIV><FONT face="Times New Roman"></FONT> </DIV>
<DIV><FONT face="Times New Roman">One among three hard disks constituting a LVM
logical volume has failed.<BR>When trying boot without the broken hard disk,
following error message come out.<BR>Couldn't find uuid with
'c3r7Sx-aTpd-JHFp-iT3c-FOiK-g7JC-uj10VK'</FONT></DIV>
<DIV><FONT face="Times New Roman"></FONT> </DIV>
<DIV><FONT face="Times New Roman">And I found another PV uuid
'7I7F4S-pzze-dgjr-0HKP-ccX4-qG1d-SOu2ki' from a new hard disk.</FONT></DIV>
<DIV><FONT face="Times New Roman"></FONT> </DIV>
<DIV><FONT face="Times New Roman">I think the PV uuid is recorded in somewhere
of LVM config so that we typed pvdisplay, it comes out.<BR>Now, I think if I can
change the PV uuid from 'c3r7Sx-...' into '7I7F4S-...' in LVM, I can manage to
boot and to recover data from the two still-healthy hard disks.</FONT></DIV>
<DIV><FONT face="Times New Roman"></FONT> </DIV>
<DIV><FONT face="Times New Roman">How can I change the PV uuid information
recorded in the LVM? or Where are the PV uuids recorded?</FONT></DIV>
