Unable to make aufs union mounts read-write

Beren Erchamion · 08-11-2015, 03:03 PM

So I've got two systems, lucyvanpelt and schroeder.

lucyvanpelt's /home is exported read-write to schroeder via nfs. Its location on schroeder is /mnt/home/lucyvanpelt

I want to union-mount it with schroeder's home, so I do as follows:

Code:

mount -t aufs -o br:/mnt/home/lucyvanpelt:/home none /home

It works just fine, except:

Code:

mount: block device none is write-protected, mounting read-only

And I'm not sure what to do about this. Like I said, the NFS export from lucyvanpelt is read-write (I have triple-checked this, though I don't know if it'd be relevant if it weren't).

Hello Beren Erchamion,

Just to be sure, can you please post the result of the command on NFS server:

Code:

cat /etc/exports

And also the command:

Code:

showmount -e "IP/Hostname of your NFS server"
