Folks,
When using sharenfs, do I really need to NFS export the parent zfs
filesystem *and* all of its children? For example, if I have
/zfshome
/zfshome/user1
/zfshome/user1+n
it seems to me like I need to mount each of these exported filesystems
individually on the NFS client. This scheme doesn't seem optimal. If I
have tens of thousands of users, each with their own little ZFS
filesystem (necessary because ZFS doesn't do user-based quotas), I don't
want to NFS mount all of these filesystems on a single node. Also, on
Linux, since anonymous filesystems like NFS do not have a block device
associated with them I can only have 255 of them mounted on a single host.
Am I missing something?
Well, it would seem that one appropriate direction to investigate
taking here would be to stop using an operating system like Linux
that places arbitrary restrictions on the number of NFS filesystems
that you can have mounted :-)
Can you use an automounter on Linux so that it only mounts the
NFS filesystem for users active on the machine or do you have
tens of thousands of concurrent users or is it something like
a mail server, storing mail in $HOME ?
