Found duplicate PV and Couldn't find device with UUID errors
 
Hi,

A long time ago i created an logical volume using this tutorial and it worked perfect until now, on ubuntu desktop.
Now, when i open the server, i have this message before i enter OS:
"Press s to skip mounting or m for manual recovery."
I pressed "s" but logical volume it doesn't work.
Thanks,

Those are my outputs:

Did you recently dd one partition to another or maybe are you doing LVM mirroring?

Are the disks presented from a storage array that possibly is giving you 2 paths to each (via SAN or iSCSI maybe)?

You can have multiple disks with the same UUID in situations like that (and in fact except for the dd situation WANT them.)

No i didn't do anything like that.
I did something stupid though...
The hardware is an hp microserver gen 8.
1 ssd - ubntu desktop os
4 hdd 3tb - volume group

I have another server configured identically to this one and, the hdd's and ssd are configured like this:

Sometimes we have electricity blackout and the servers are rebooting. After that hp doesn't retain the array settings, i don't know why.It doesn't happen every time but it's happens and i have to recreate the array with the ssd like in above picture and everthing is fine.

The last time, with the problematic server, by mistake i created an array with the ssd (which is fine) and, another one, with the 4 hdd's (which was not fine) and uuid problem appeard:
