Error with cvmfs_server snapshot command

Hello.
I am new to using CVMFS and am having trouble setting it up the first time.

Currently, the “cvmfs_server snapshot” command is not working and has stopped working.
When I enter the command, it says “failed” and I cannot get a snapshot.
The following error message is displayed.

Please help us resolve this issue.

Hello!

Is this a new repository that you are administering? Then I would first check if the whitelist has been signed on the stratum 0. See 2. Stratum 0 and client - CernVM-FS tutorial

If that does not help let me know in order to investigate further.
Cheers,
Valentin

Thank you.
I checked your link.
“resign” but it did not resolve the issue.

You may be missing a file needed for migration.
Where is the whitelist usually stored?

The whitelist is stored on the server at /srv/cmfs/<reponame>/.cvmfswhitelist. Then the stratum 1 is configured with a key or list of keys that it checks the signature on that against.
