How to mount a device /dev/sdb2 in opensuse ?
 

Hello,

Two disks have been cloned and look same, since UUID is identical. The OpenSuse Leap 15.3 won't mount it.

How to force it?

Regards

probably try another mount point

No, the OP had better learn to backup properly rather than insisting on forcing a very poor option. The system is protecting itself from them.

nope. not working

it is not a protection. The root account shall have full power.

How to remove this kind of protection of OpenSUSE to let it free and full power?

? I don't understand ? root does not mean god mode, you will never have full power to do whatever to want, there are limitations (like you cannot ride two horses in the same time)
In linux (and indeed everywhere) there are rules that cannot be ignored or overridden.

Change the UUID on the device that is not mounted.

Mounting two devices with the same identifier would be like filing taxes when two people have the same Social Security number. Bad.

This isn't about superuser power. The kernel is not designed to accommodate multiple devices with identical UUIDs. Corruption is inevitable if attempted. Either don't include the clone in the same system as the original after the clone has been completed, or uniquify all before proceeding with use of clone and/or original.

this is complete ...
If you use /dev/... without automount, all will be fine.

I don't understand this statement, but I guess (or it looks like) automounter mounts something what you don't need. So do not automount it. Or umount it. Do whatever you want, but don't try to mount and unmount the same device at the same time. This is simply impossible.

you can mount the same device at two locations at same time, it is possible. depends which kernel/linux distro.

Yes, but you have to use the remount option for the second instance, and it is still BAD=B*A*D to mount two devices with the same UUID! Please try to avoid that.

Your original post is not related to this, that is a different error.
Would be nice to explain all the details....

Please would you mind telling me how to remove that locking? this unlocking for more powerful usage would be needed

Kind regards

Smoking is *bad* as well.

Still, you cannot force people to not smoke. There are still people smoking in the street.

 

To extend that insane comparison, nobody is required to provide smokers with a source of nicotine.


If anyone knows how to do what you want and doesn't think it's a bad idea, they will doubtless provide respond.

Alternatively you could try asking the people who added the restriction: if you can justify your reasons to them, they are best placed to provide a solution.
