/dev/sda1 has a duplicate file system

Post by jrohrauer »

Hi,

I did a test restore from a machine to a blank vm, worked like a charme. Then i reran the job on the source with services disabled to get all the data on the destination machine.
seems to work, but this message makes me wonder:

before submitting the restore job i was told that all partitions will be deleted. Can anyone tell me what this message with the duplicate file system then means?

Thanks
Johannes

I'm thinking this has to do with UUID's not being unique. Can you run blkid -a and paste the output?

Hi Niels,

this is the output from blkid (without -a - this parameter does not exist?):

Code: Select all

/dev/sda1: UUID="ac0edbc1-3cdb-4706-89be-fe31f125cd13" TYPE="ext2"
/dev/sda2: UUID="36d7ed74-30bc-4f1c-bfc5-1a888f59b58b" TYPE="swap"
/dev/sda3: UUID="5eb97639-89ad-4249-93fd-0f71ea4db89c" TYPE="ext4"
/dev/sda5: UUID="74faa428-7490-4a76-8cbe-b2d1522c3bd9" TYPE="ext4"
/dev/sda6: UUID="11875bac-6b83-4f8c-b07d-736968344227" TYPE="ext4"
/dev/sda7: UUID="ad372877-396c-4e9b-bfd7-3d598345943e" TYPE="ext4"
/dev/sda8: UUID="7df16fcc-587c-4d48-ac9a-f1f05f1e639f" TYPE="ext4"
/dev/sda9: UUID="842ba875-a415-4053-a409-1a48669a0ca7" TYPE="ext4"
Just to clarify: I ran this command on the restored machine (which btw works fine). Hope this is what you wanted me to do or do I need to boot from the recovery media again and run it from there?

Thanks
Johannes

Hi,

Glad that everything worked fine! As you could see in Recovery Media UI we provide you with a simulator so you can edit the filesystem to restore to and that is where the issue came from - the software basically detects that some filesystem from the simulation is identical to the filesystem in the backup. The software itself treats the simulation like if it was a real filesystem thus start complaining about duplicates being present. It's considered to be a bug and is already fixed for GA.

Thanks!
