[lustre-discuss] Linux users are not able to access lustre folders

[Ravi Bhat]

Hi,
After copying users details from lustre client /etc/passwd to lustre MDS
server, it's working fine.

Now, I have bright cluster manager in my headnode, which has LDAP server.
How do I configure my lustre servers to use that LDAP server?

Regards,

Note that the "luser6" needs to have the same numeric UID/GID as on the
clients.
Copying /etc/passwd to the MDS is the easiest way to do this (it isn't
needed on the OSS nodes).  You probably do NOT want to copy /etc/shadow to
the MDS, to prevent regular users from logging in there.

You can check that this is configured correctly by running on the MDS (as
root):

  /usr/sbin/l_getidentity -d {uid}

to verify that "uid" is accessible from /etc/passwd (or
NIS/LDAP/AD/whatever).

Cheers, Andreas

are visible to the lustre servers.  You could also use LDAP or even just
/etc/passwd.   You’ll probably just want to choose whatever mechanism is
used on your other systems.
