Hello.

My problem:

root@backup# /usr/bin/pbm delete-backup -f 2020-11-02T11:35:26Z --mongodb-uri="mongodb://mongo1.server:27000/"
Waiting for delete to be done ..[done]

pbm can`t delete backup archive from a remote server “backup.server”. But on the host, this command works.
Logs :

1/02 15:32:30 Got command delete [{delete { } { } { 0} 1604320350}]

Help my plz. Now I can only delete backups from mongo1.server,mongo2.server,arbirt.server.

Hi, this could be an issue with NFS setup… Create a test file manually and try removing it from the remote servers. Does it work?

if you can paste here the content of /etc/exports on the nfs server and the output of mount command on the client side.

I did not quite get your idea.

mongo1.server# echo 'password' |sshfs -o reconnect,allow_other user@user.ftp-backup.com:/mongo_backup /mnt/mongo_backup/ -o password_stdin
mongo1.server# mount | grep mnt 
user@user.ftp-backup.com:/mongo_backup on /mnt/mongo_backup type fuse.sshfs (rw,relatime,user_id=0,group_id=0,allow_other)

I successfully create backups on different servers:

mongo1.server# /usr/bin/pbm backup --mongodb-uri="mongodb://mongo2.server:27000/"

Ok I see what you mean now, sorry I didn’t get it before. This looks like a bug, would you mind opening a ticket in https://jira.percona.com/projects/PBM/issues with the info?

I can do it. Do I need to copy the comands from this dialogue to the ticket or is it enough to attach the link to this dialogue?
