this hard-drive has changed its UUID to 0x. What is telling you this? fdisk -l
That's not the UUID that LVM reads. Actually, that's not a UUID at all, it is not enough bits.
Well, actually it says '00000000x'
To see the UUIDs on the system as LVM sees them issue the command: pvscan -u
Booting from the system, this gives: Couldn't find device with uuid ' lLWxB7-QmLl-FMXX-KQRW-EDH2-EHLL-o7D21b' Couldn't find device with uuid ' lLWxB7-QmLl-FMXX-KQRW-EDH2-EHLL-o7D21b' Couldn't find device with uuid ' lLWxB7-QmLl-FMXX-KQRW-EDH2-EHLL-o7D21b' PV /dev/sda4 with UUID ecQz2l-Yl5S-s1AR-delt-5zXF-Wnjs-P2y2dH VG system lvm2 [113.03 GB / 0 free] PV /dev/sdb1 with UUID 5P6jGx-ePjX-43Az-wyLL-wuF5-R4Vt-vP9Uff VG system lvm2 [465.76 / 0 free] PV unknown device with UUID lLWxB7-QmLl-FMXX-KQRW-EDHZ-EHLL-o7DZ1b VG system lvm2 [465.76 GB / 224.54 GB free] Total: 3 [1.02 TB] / in use: 3 [1.02 TB] / in no VG: 0 [0 ] When I boot from the GParted live-CD: PV /dev/sdb4 with UUID ecQz2l-Yl5S-s1AR-delt-5zXF-Wnjs-P2y2dH VG system lvm2 [113.03 GB / 0 free] PV /dev/sdc1 with UUID 5P6jGx-ePjX-43Az-wyLL-wuF5-R4Vt-vP9Uff VG system lvm2 [465.76 GB / 0 free] PV /dev/sda with UUID lLWxB7-QmLl-FMXX-KQRW-EDHZ-EHLL-o7DZ1b VG system lvm2 [465.76 GB / 224.54 GB free] Total: 3 [1.02 TB] /in use: 3 [1.02 TB] / in no VG: 0 [0 ] No error at all. How does the GParted Live-CD do that?
Assuming nothing is wrong with the drive, you should be able to run pvcreate and specify the UUID that LVM is expecting and it will write the new PV meta-data
I will try that, as soon, as we will have backuped the data.
without affecting any other sectors on the drive/partition.
That was something, I was afraid of. They haven't a backup so far.
Even if you can't mount the drive, you can take a dd_rescue copy of it before you make changes to any of the data on it.
I will buy a 1TB external hard-drive and backup, what the client considers important. Thanks! -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
