Steps To Reproduce:

1. Have mongo set up on two computers, one of which having databases to copy over

2. copy contents of old computer to flash drive modifying permissions if needed

3. delete all files in the dbpath directory (/var/lib/mongodb in this case)

4. Copy over all copied files

5. Reset permissions

    a. folder is 755

    b. files are 600

    c. diagnostic.data and journal are 700

6. run mongod

 Description   

Hello, running two computers with Ubuntu and wanted to transfer the databases from one to the other as we are upgrading the system here. The dbpath on both was /lib/var/mongodb, I changed the permissions on the files to allow them to be copied, moved them to a hard drive and copied them onto the new computer in the same directory. I also removed existing files from that directory (not sure if that could be the problem, I backed up most). When I first dropped the files in I chose not to clear out existing files or overwrite duplicate files, mongo ran after but I was unable to see the databases I just added. So then I cleared all local files in /lib/var/mongodb and replaced with the files from the other computer. For some reason the default dbpath changed even though it still calls out the expected in the config file(an annoyance but not the problem here). Running mongodb with the appropriate path resulted in issues, but it suggested the repair option so I ran that but that failed  (included below the mongod with dbpath command)

Here is a printout from running mongod with the dbpath.

Hi ian.wilson@berkshiregrey.com,

We still need additional information to diagnose the problem. If this is still an issue for you, would you please let us know if you stopped all writes before you copied the contents to the other computer?

Best,
Edwin

Hi ian.wilson@berkshiregrey.com, before you copy files in your step #2, did you stop all writes as explained in our documentation?

Comment by Ian Wilson [ 09/Jun/20 ]

I replaced the files with the original files + the ones I added and I see some existing data in databases but nothing in the databases I was hoping to transfer over. I am ok with losing the data on the newer computer, just want to save the data from the older computer
