Restrictions and Known Issues

  • go-xcat install sometimes fails with checksum or signature errors when downloading dependency packages. When that happens, try go-xcat --xcat-version=2.15 install or point directly to dependency zip file with go-xcat --xcat-dep=https://xcat.org/files/xcat/xcat-dep/2.x_Linux/xcat-dep-2.15.1-linux.tar.bz2 install

  • When provisioning a node with a diskfull install of RHEL 8.0 or RHEL 8.1 using the default osimage definitions, the disk partitioning rules included in /opt/xcat/share/xcat/install/scripts/pre.rhels8 will create a 20G / filesystem if the disk is 65G or greater. This behavior will be changed in the next xCAT release to create a / filesystem that uses all available space on the disk rather than limiting the filesystem to 20G. For users who wish to provision diskfull nodes with larger / filesystems using xCAT 2.15.1, the pre.rhels8 can be patched with the updated version using the following procedure:

    • wget https://raw.githubusercontent.com/xcat2/xcat-core/master/xCAT-server/share/xcat/install/scripts/pre.rhels8
    • Make a copy of existing /opt/xcat/share/xcat/install/scripts/pre.rhels8
    • Replace /opt/xcat/share/xcat/install/scripts/pre.rhels8 with the one downloaded with wget.
    • Reprovision compute node.
