Clean NFS Share

[milocheri]

Hello, good afternoon, here it's what happened

I just install Proxmox on a OVH dedicated Server wich includes 500GB of NFS storage, so i decide to create a Proxmox Backup Server VM, and mount that nfs storage to the vm
Steps:
1.- create a directory inside Proxmox Backup Server VM
2.- Mount the NFS Storage to that directory

3.- I add the directory as Datastore in Proxmox Backup Sever

4.- Everything was just fine, the full storage was detected (500GB) , however i decided to change the Name, so i delete the Datastore, and add it again, and now the size detectes is 16.97GB





Is there any way to clean it in order get the right amount, in OVH it shows 500GB, in the vm in cli also shows the correct size, only in Proxmox Backup Server Gui is wrong, thanks!

Well, you created the datastore at /nfs, but it is mounted at /root/nfs. Therefore, it is now using the root filesystem of the machine.
Remove it and create a new one with /root/nfs as path if that is where you mount the share.

I did a fresh reinstall, i create a directory as NFS, i mount the NFS Share

Then i tried to mount, but i got an error message



It only allows me to add the Datastore with the Path /NFS, and there is where it shows the wrong size

/NFS

Well, that isn't where the NFS share is mounted though, according to the `df -Ht` screenshot. Are the permissions set correctly, that you can write to the NFS share? For example, touch /root/NFS/testfile?

I'm able to mount the share as /NFS or /root/NFS
touch /root/NFS/testfile it didn't create the file, but touch /NFS/testfile Yes

If you're creating a file in /root/NFS, and looking for that file in /NFS, I would find it strange if it would be there.
try running the command
ls -l /root/NFS
I would suspect the other testfile to be there too.

Judging by the screenshots, /NFS is "just " a folder on your PBS-filesystem (which is why you see the 16 GB), whereas /root/NFS is a folder linked to your NFS-share (where you should see the 500GB).

If i add the datastore as /NFS i only see 16.97GB, but if i tried to add as /root/NFS i get the error "EPERM: Operation not permitted"

Have you checked that your server is allowed to write to that NFS-share?

Also try running these:

mkdir /mnt/Backup-NFS
chown backup:backup /mnt/Backup-NFS
chmod 775 /mnt/Backup-NFS
mount -t nfs ftpback-bhs1-8.ip-198-100-151.net:/export/ftpbackup/ns5019519.ip-15-235-119.net /mnt/Backup-NFS
chmod -R 775 /mnt/Backup-NFS
touch /mnt/Backup-NFS/testfile-new
ls -l /mnt/Backup-NFS/

(used this as reference for the above)

Hello, thank you for your reply, i follow step by step, but i'm still getting the error "EPERM: Operation not permitted" when adding the Datastore

I tried mount the storage as a directory in the PVE, and also it shows 500GB, the only problem is with PBS

I also mount it in Windows






I don't know what else to do

 

[milocheri]

Hello, i'm still have the issue, do you think there's no way to use PBS with the NFS Storage of OVH ? thanks!
