On a VM in azure we mount some blob storage via NFS, which generally works good. I now found though, that df
reports wrong values for usage of the NFS storage:
root@myVM:~# df -h /mnt/blob/
Filesystem Size Used Avail Use% Mounted on
storagename.blob.core.windows.net:/storagename/data 5.0P 0 5.0P 0% /mnt/blob
As you can see, it looks like we don't have any data in /mnt/blob
, which is wrong. We stored lots of files there.
We are running current Debian 11.6 there and used these mount options:
storagename.blob.core.windows.net:/storagename/data /mnt/blob nfs nfsvers=3,nolock,proto=tcp 0 0
Is this
- related to Azure (mounting blob)
- related to huge FS (several petabyte)
- maybe network related (tcp -> firewall?)
Any hints are welcome.
