ZFS shared with NFS makes directory cover filesystem
I'm having a strange issue that I'm unsure what to do with. I have a new Solaris home server that I want hard mount /home to all our servers. I've made each user's home directory a filesystem so that I can manage every user with a quota. In each one of my server vfstab files I have it set as:
home-server:/DATA/home /home nfs - yes bg,rw, soft
The zpool is called DATA with a filesystem called home and each users home directory is a filesystem under that. So for example one could be /DATA/home/homer on the home server that would mount /home/homer when a user logs in to any server.
The issue is that when I log into a server, a new directory (not filesystem) is created with the exact same name on the home server under /DATA/home and it ignores that there is a filesystem there already. It's like a directory is created and it masks the users home filesystem. On the home server, I have to "zfs unmount DATA/home/homer" and then I can delete the directory that was created. I don't want to have to create a line for each user on each server's vfstab file, so is there a whilecard or something that I need to add?
I don't have this issue when I use automount. I don't like using automount because I sometimes have issues with it screwing up with LDAP and I have to login as root and restart it.
Thanks for the help!

I created a zpool and two ZFS volumes in OpenSolaris. I would like both ZFS volumes to be exportable. However, I don't know how to set that up.

Hey all,
I have a machine with 16 drive slots. Two of the drives have a ZFS mirror of the operating system, the other 14 contain the storage raidz.
So, after installing Opensolaris on the OS drives, how can I remount the storage raid?

sss_useradd
SSS_USERADD(8) SSSD Manual pages SSS_USERADD(8)
NAME
sss_useradd - create a new user
SYNOPSIS
sss_useradd [options] LOGIN
DESCRIPTION
sss_useradd creates a new user account using the values specified on the command line plus the default values from the system.
OPTIONS
-u,--uid UID
Set the UID of the user to the value of UID. If not given, it is chosen automatically.
-c,--gecos COMMENT
Any text string describing the user. Often used as the field for the user's full name.
-h,--home HOME_DIR
The home directory of the user account. The default is to append the LOGIN name to /home and use that as the home directory. The base
that is prepended before LOGIN is tunable with "user_defaults/baseDirectory" setting in sssd.conf.
-s,--shell SHELL
The user's login shell. The default is currently /bin/bash. The default can be changed with "user_defaults/defaultShell" setting in
sssd.conf.
-G,--groups GROUPS
A list of existing groups this user is also a member of.
-m,--create-home
Create the user's home directory if it does not exist. The files and directories contained in the skeleton directory (which can be
defined with the -k option or in the config file) will be copied to the home directory.
-M,--no-create-home
Do not create the user's home directory. Overrides configuration settings.
-k,--skel SKELDIR
The skeleton directory, which contains files and directories to be copied in the user's home directory, when the home directory is
created by sss_useradd.
This option is only valid if the -m (or --create-home) option is specified, or creation of home directories is set to TRUE in the
configuration.
-Z,--selinux-user SELINUX_USER
The SELinux user for the user's login. If not specified, the system default will be used.
-h,--help
Display help message and exit.
THE LOCAL DOMAIN
In order to function correctly, a domain with "id_provider=local" must be created and the SSSD must be running.
The administrator might want to use the SSSD local users instead of traditional UNIX users in cases where the group nesting (see
sss_groupadd(8)) is needed. The local users are also useful for testing and development of the SSSD without having to deploy a full remote
server. The sss_user* and sss_group* tools use a local LDB storage to store users and groups.
