Hello, there are conflicting messages in the output above. Does pbm user have permissions for mongodb dir? e.g.

usermod -a -G mongod pbm

Did the primary change while you were trying the restore?

Hello igroene!
Thanks for your reply！

I run mongod and pbm-agent with root user

[root@hostname ~]# ps aux|grep pbm
root      7361  0.1  0.0 1034972 14752 ?       Ssl  09:41   0:00 /usr/bin/pbm-agent
root      9310  0.0  0.0 112708   972 pts/0    S+   09:47   0:00 grep --color=auto pbm

And no changes on primary during recovery.

mongod in the $PATH:

[user@hostname ~]$ which mongod
/percona-backup-mongodb/bin/mongod

there are the logs:

It seems that all the data has been copied to the data directory, but the mongod cannot be found when starting the mongo service.
