====== Mount drives in Ubuntu with EVMS ======



===== EVMS not supported by Ubuntu anymore =====
They say that it has been unmaintained for more than a 1.5 years now, and interferes with the 2.6 kernel. Best I start looking for another solution. mdadm here i come :-/

===== Deprecated instructions =====
[[wp>Enterprise Volume Management System]] (EVMS) mounts harddrives and disk storage space in Linux in advanced and flexible ways. See its website and [[http://evms.sourceforge.net/user_guide/|user guide]] for details.

In Ubuntu, I originally had to use its auto-installer to find and install EVMS binaries. I traditionally have used the EVMS ncurses interface, which is a [[wp>text user interface]].

  * ''sudo evmsn'' or ''sudo evmsgui''
  * find needed logical volume 
    * ''/dev/evms/lvm2/Media/Car...''
  * hit ''Enter'' to get menu options
  * choose ''Mount...''
  * enter directory where you want the volume to mount
    * ''/media/documents''
    * this was retrieved from the end of my custom samba configuration file smb.conf
      * ''sudo nano -w /etc/samba/smb.conf''

FIXME I need to automate this mount on startup, possibly by learning how to do the mount through EVMS in Command Line Interface, and then putting that into the fstab file.

====== Connect manually from a mac ======
  * Ctrl+K in finder
  * smb://lms
    * MSHOME
    * nyeates1
    * password




====== udevd && EVMS issue ======
  * udevd process was gobbling 50% CPU and disk thrashing from writing to log files constantly
    * EVMS official explanation http://evms.sourceforge.net/install/kernel.html#bdclaim
    * Bug and comments https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/115616
    * Following command to stop udev / udevd 
      * <code shell>sudo udevd stop</code>
      * <code shell>sudo /etc/init.d/udev stop</code>
    * If that didnt work, I ungracefully 'killed' the process 
      * <code shell>
top
sudo kill 25293
          </code>
    * Add the following lines to configuration file **/etc/evms.conf** on the ''sysfs_devices.exclude'' section. Per directions on evms sourceforge link above.
      * <code>
        # This line will exclude some disks that are alread being used  
        # by the root OS. There is a problem with both the kernel and
        # EVMS trying to get to the same disks. See the following link:
        # http://evms.sourceforge.net/install/kernel.html#bdclaim
        # exclude = [ hda sda ]
        </code>
