  • 1.  About creation of Dsource and getting the error

    Posted 14 days ago

    Hello All,

    We've established a mount point for PostgreSQL, and during the creation of the dSource, we've encountered a situation where the permissions of PostgreSQL are being altered to root.

    And this is the error we are getting in the Delphix Engine

    Thanks,

    Hi Harsha,

    Could you share the output of sudo -l -S for user postgres? I'd recommend opening a support case with Delphix Support for further log reviews. 

    Cheers!

    Hi Harsha,

    Can you please check your /etc/sudoers file and confirm that you have a similar configuration for the postgres user?

    Defaults:postgres !requiretty
    postgres ALL=NOPASSWD:  /bin/mount,/bin/umount,/bin/mkdir,/bin/rmdir

    The output above seems to imply that is not configured as we expect it: Postgres Sudo Requirements

    You could also try to run sudo /bin/mount, sudo /bin/umount while logged as postgres to see if you get a prompt for the password.

    If you would like to raise a support case and attach a support bundle, we may be able to investigate this further for you.

    Hello,

    The mount point (/mnt/provision) must be owned by the Delphix operating system user. It looks like our PostgreSQL documentation is missing that point so I will file a documentation bug.

    Other datasets note this requirement ( target host requirements ):

    There must be a directory (e.g. "/mnt/provision/" or "/mnt/staging/") that will be used as a container for the NFS mount points that are created when provisioning a VDB or linking a staging push dSource.

    The delphix_os user and primary OS group (i.e. oinstall or dba) must own the directory.

    The directory must have at least permissions -rwxrwx--- (0770).

    There must be no symbolic links in the path of this directory, because NFS can mount into a directory with symlinks in its path, but cannot unmount.

    Thanks,

    Neal
