Sounds like the update may have renamed the old devices to something new. This has happened once to be with a Dell Equallogic firmware update. Are you mounting the devices using a device name or using device labels? If the former you should use labels if you created them or the UUID. If you have a look in /dev/disk you'll see all the options available to your OS. If you choice to go with UUID then have a look in /dev/disk/by-uuid to get the path
Hi,
on that storage I did not used labels AFAIK ... it was long ago that I set that up. So I looked up the uuid, but dont got a working clue for me.
I than tried the steps from Hal Martins mail removing the LVM settings etc and created a new LVM (PD/VG) with the settings I used for installing the storage on the old server.
But I still cant mount the volumes.
May be I messed more up than to fix? :(
We dont use multipathing on that storage.
ANY suggestion and hint is very welcome!
Thanks and best regards. Götz
