Operating Systems Solaris ZFS shared with NFS makes directory cover filesystem Post 302929896 by achenle on Sunday 28th of December 2014 06:16:56 PM

Is the automount service online on your NFS clients?

When you explicitly mount home_server:/DATA/home on the client at /home, you're conflicting with the automount service if it's online. I don't recall offhand what happens if you do that.

On your home server, what do you see at /DATA/home if you unmount all the user file systems? That's what gets mounted on the clients when you mount home_server:/DATA/home there. No file systems mounted under the file system shared by NFS are implictly exported from the server, and even if they're explicitly exported from the server they won't be mounted on the client, although some NFSv4 clients will silently mount such nested file systems.

mountd(1M)																mountd(1M)

NAME
mountd - server for NFS mount requests and NFS access checks SYNOPSIS
/usr/lib/nfs/mountd [-v] [-r] mountd is an RPC server that answers requests for NFS access information and file system mount requests. It reads the file /etc/dfs/sharetab to determine which file systems are available for mounting by which remote machines. See sharetab(4). nfsd running on the local server will contact mountd the first time an NFS client tries to access the file system to determine whether the client should get read-write, read-only, or no access. This access can be dependent on the security mode used in the remoted procedure call from the client. See share_nfs(1M). The command also provides information as to what file systems are mounted by which clients. This information can be printed using the show- mount(1M) command. The mountd daemon is automatically invoked by share(1M). Only super user can run the mountd daemon. The options shown below are supported for NVSv2/v3 clients. They are not supported for Solaris NFSv4 clients. -r Reject mount requests from clients. Clients that have file systems mounted will not be affected. -v Run the command in verbose mode. Each time mountd determines what access a client should get, it will log the result to the con- sole, as well as how it got that result. /etc/dfs/sharetab shared file system table See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWnfssu | +-----------------------------+-----------------------------+ nfsd(1M), share(1M), share_nfs(1M), showmount(1M), nfs(4), sharetab(4), attributes(5) Since mountd must be running for nfsd to function properly, mountd is automatically started by the svc:/network/nfs/server service. See nfs(4). Some routines that compare hostnames use case-sensitive string comparisons; some do not. If an incoming request fails, verify that the case of the hostname in the file to be parsed matches the case of the hostname called for, and attempt the request again. 27 Apr 2005 mountd(1M)
