Hi All...

I created an NFS share using Microsoft Storage Server. I had no trouble adding the NFS share to Proxmox 2.2. However, if i try to backup a container, or create a new container, to the share, I get a popup window displaying this error message:


mkdir /mnt/pve/NFS1: File exists at /usr/share/perl5/PVE/Storage/NFSPlugin.pm line 139 (500)

I confirmed ont he server that there are no files at all in the share. Also, I did allow root permissions. I am using anonymous authentication.

I had a look at the code in this source file but it didn't make any sense to me.

Suggestions appreciated, thank you.

hello,
I know this is a big post Down Pressure, but as I have encountered the same problems, I tell myself that it could help someone.

When you delete a storage element, its volume may still mounted on /mnt.

If you:
- Delete a storage volume at proxmox web GUI
- Recreate it with the same name at proxmox web GUI
- The error "File exists at /usr/share/perl5/PVE/Storage/NFSPlugin.pm line 139 (500)" appears

do a:
find /mnt -name <name of volume storage>

You must have a result: /mnt/<name of volume storage>

do a umount /mnt/<name of volume storage> on each node accessing this volume.
Repeat the command to ensure that the operation was successful ("umount: /mnt/<name of storage volume> is not mounted)

From there, you can do your storage volume again.

Hello.
I had the same problem, so the process I performed was:
ls /mnt/pve
root@SPESRVDEBF001:~# ls /mnt/pve Backup Backups GPD Imagens ProxmoxGPD Teste BACKUP gpd gpd2 ISO SPE-SRV-BKP

I checked the drives I had deleted through the GUI(WEB).
Then I ran the following command:
umount gpd2/ BACKUP/ Backup/ GPD/ ProxmoxCluster/ ProxmoxGPD/ Teste/
root@SPESRVDEBF002:~# umount gpd2/ BACKUP/ Backup/ GPD/ ProxmoxCluster/ ProxmoxGPD/ Teste/

Then I gave the command:
rm -rf gpd/ gpd2/ BACKUP/ Backup/ GPD/ ProxmoxCluster/ ProxmoxGPD/ Teste/

What is the output of

Just encountered a similar issue on PVE 7.4-3 using SMB (not NFS), solved with what others suggested above.
I got a `File Exists` error on `/usr/share/perl5/PVE/Storage/CIFSPlugin.pm line 231` while I was trying to create a SMB storage under `Datacenter -> Storage`.

This seems to be a bug.
@dietmar Are you able to add this to Bugzilla? I'm not able to since I don't know what this is related to. Thanks!
