curlftpfs - EPERM: Operation not permitted

[sheshman]

Hi,

Using Linux 5.15.102-1-pve #1 SMP PVE 5.15.102-1 (2023-03-14T13:48Z) backup server and wanted to backup to ftp server, installed curlftpfs and mounted to /mnt/backup, when i "ls" i can see folders, create file or folder without any problem through ssh, but when i try to add as datastore it returns EPERM: Operation not permitted.

Mounting my ftp to folder as :

curlftpfs myuser:'mypassword'@192.168.1.245 /mnt/backup -o rw,allow_root

I believe it's related to folder permissions somehow root user can read,write & delete in ftp mount but backup server is not able to get ownership of the ftp mount?

Screenshots as attached.

Hi,

Can you try to write a file in your FTP datastore using the following command?

sudo -u backup touch foobar.txt

Hi Moayad,

Thanks for your reply, when i tried your suggestion it returned "Permission denied" i think that's the problem, also tried ;

chown backup /mnt/backup

but it returned "Operation not permitted", i'm a rookie about linux don't know what else should i try to give permission to backup user to that folder. FTP folder's permissions are already 777

 

[sheshman]

any advice? I'm really stuck on this step

You have to set the permission from the FTP server to the backup user.

Sorry for late reply, i've tried to create user as "backup" on ftp side but it doesn't allow me to create a user name "backup", it's one of the hosting companies and they are automatically creating user names, is there any work arround?

 

[sheshman]

update :

i was able to mount ftp as;

sudo -u backup curlftpfs username:'password'@myserver /mnt/yedekler

after this command touch worked : sudo -u backup touch /mnt/yedekler/foobar.txt


when i try to mount i'm getting : unable to create chunk store 'backupstor' at "/mnt/yedekler" - EACCES: Permission denied

Folder permissions already set to 777 and hosting company says they can't give permission to any other user to ftp storage,i need to use my username provided by them, any advice?

@Moayad terribly sorry to bother you but any advice will be appreciated

Hi,

Sorry for the late answer, The datastore should have permission for the backup user on your FTP, you have to do that in your FTP server.
