We are having a problem with one of our evms volumes. The volume is a
DriveLink object with two connected harddisc segments on two different
harddiscs. After a reboot, the volume was not available and the evmsgui
indicated that the volume was missing a child. The correct segment was
replaced bij a "link_missing_child" DriveLink object. The correct disk
segment is available in the "available object" tab.
The context menu of the "link_missing_child" object has an option
"Replace Missing Child". If i select this, i get a screen with the
available objects, containing the correct disc segment. I hope / guess
that this would restore the original configuration and solve our problem.
But because the volume contains valueable data, i want to be really sure
this doesn't go wrong. Does anybody have experience with this kind of
problem? And can anybody confirm that replacing the missing child object
makes the volume available again without corrupting the filesystem? Or
is there a better way to solve this problem? And is there a way to
backup the meta_data when the "backup" option in the "action" menu of
evmsgui gives an error?
The volume is an 12 TB XFS filesystem, evms is version 2.5.3 on Suse
Linux 10.0 on a x86_64 system.
Thanks in advance,
