I’m currently setting up NFS based file sharing between my Mac client (Macos 10.14.1) and Raspberry Pi3 server (U16.04.1 LTS). As I dual-boot my Mac (MacOS/Ubuntu18) I want to use my Pi with NFS (I already have Samba running well, but it doesn’t handle Unix permissions) as a common home to reduce duplication of files and simplify version control. After I get MacOS working properly, I will tackle the Ubuntu setup.
I have two shares setup at the moment, one using NFS3 (anonymous), the other using NFSv4 (home/user1). Reading/writing files to either of the shares is very fast and working well (other than UID/GID mismatches). Where I have a problem is that whilst listing the files on the NFS3 share is also very fast, listing files on the NFSv4 share is VERY slow and I can’t figure out why.
Below are all the settings I’m using. I haven’t used
mount --bind on the server as I don’t think its necessary and doesn’t have anything to do with my problem, but I may be wrong.
I’ve been searching for solutions to this problem for a number of days however nothing I’ve read addresses my problem, whereby others always complain about directories with large numbers of files, nor have any of the suggestions I’ve seen fixed my problem.
Ultimately, I want to synchronise UIDs/GIDs between my Mac and Pi, but that is another question as I don’t now much about setting up LDAP (or using NIS?) with (but hopefully without) Kerberos. In addition, I don’t have a domain controller setup right now.
Thanks in advance for taking the time to read about my problem and your suggestions.
