ID Mismatches on OES 1
On OES 1, problems occur when additional OES NetStorage servers with NSS volumes are installed
in the same eDirectory container. Because the UIDs and GID are assigned by the system, unless the
installation process is exactly the same for each OES 1 server, the UIDs and GID don't match
server-to-server.
When the local X-Tier UIDs and GID on subsequently installed servers don't match the X-Tier
UIDs and GID in eDirectory, NetStorage can't access the NSS volumes on the server.
The OES 1 Solution: the nssid.sh Script
To solve the problem of mismatched Ids, the OES 1 installation program looks for X-Tier ID
conflicts, and if the IDs on a newly installed server don't match the IDs in eDirectory, the program
generates a script file named
check for an
nssid.sh
However, this solution is only viable through the first release of OES 2.
OES 2 SP1 and SP2 Require a New Approach
System-level changes in SUSE Linux Enterprise Server 10 SP2 and later invalidate the
script solution for mismatched IDs. Synchronizing the X-Tier IDs with an OES 1 installation can
now cause instability in other non-OES components. Therefore, starting with OES 2 SP1, you
should standardize all X-Tier IDs on existing servers before installing a new server with X-Tier-
dependent services.
The OES 2 Solution: Standardizing the UIDs on all OES servers
If your eDirectory tree has ever contained an OES 1 Linux server with NSS and LUM installed, do
the following on each server (including OES 2) that has NSS and LUM installed:
1 Log in as
id novlxregd
id novlxsrvd
The standardized X-Tier IDs are UID 81 for
for
novlxtier
2 If you see the following ID information, the X-Tier IDs are standardized and you can move to
the next server:
uid=81(novlxregd) gid=81(novlxtier) groups=81(novlxtier)
uid=82(novlxsrvd) gid=81(novlxtier) groups=81(novlxtier),8(www)
If you see different IDs than those listed above, such as 101, 102, 103, etc., record the numbers
for both X-Tier users and the novlxtier group. You need these to standardize the IDs on the
server.
3 Download the following script file:
fix_xtier_ids.sh (http://www.novell.com/documentation/oes2/scripts/fix_xtier_ids.sh)
4 Customize the template file by replacing the variables in angle brackets (<>) as follows:
<server_name>: The name of the server object in eDirectory.
Replace this variable with the server name.
