I have an AWS EFS NFS4 share (
shareA) that is mounted by some servers where all files are owned by userA/uid=800. I'd like to mount that share onto the
b-series servers, configured to look like userB/uid=900 owns all of the files. How can I do this?
The way NFS operates is that is wants UIDs/GIDs synchronized across all participants. Newer versions support mappings (with
idmapd) of local deviations, but that's pretty much it.
Aside from working with ACLs, I fear that you are out of luck.
