Support Requests item #815456, was opened at 2003-09-30 16:48 Message generated for change (Comment added) made by kcorry You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=383343&aid=815456&group_id=25076 Category: Kernel Group: Version 2.0 >Status: Closed >Resolution: Fixed Priority: 5 Submitted By: Richard Freeman (rich0) Assigned to: Kevin Corry (kcorry) Summary: Unable to connect to device mapper control device Initial Comment: When I attempt to load evms I get the errors: Engine: Unable to open the control node for Device-Mapper. The Engine will run without Device-Mapper support. Engine: The plug-in Ext2/3 in module /lib/evms/libe2fsim.1.2.1.so requires Engine services API version (8.1.0) which is less than this Engine's services API version (10.0.0). Engine: The plug-in failed to load. I don't see any devices in the gui. My guess is that the device-mapper error is causing the problem. My kernel (2.6.0-test6-mm1) does have device mapper compiled in. I did not apply any of the evms patches, but my impression in reading the install docs is that this is only necessary to use a few evms features. ls -l /dev/mapper: crw-r----- 1 root root 10, 63 Dec 31 1969 control cat /proc/devices: ... Block devices: 2 fd 3 ide0 9 md 22 ide1 254 device-mapper Let me know if you need any other details. I'm using evms 2.1.0. ---------------------------------------------------------------------- >Comment By: Kevin Corry (kcorry) Date: 2003-09-30 17:02 Message: Logged In: YES user_id=206722 Hi Richard, First, you'll need to upgrade to EVMS 2.1.1 in order to use the latest 2.6 kernels. I don't believe 2.1.0 will work with any kernel later than 2.5.73. Next, make sure you've selected the "version 4 ioctl interface" in the Device-Mapper section of the kernel configuration. Also, please take a look at the new install instructions on our web site for more info on getting EVMS working with the latest kernels: http://evms.sf.net/install/ Concerning the warning about libe2fsim: you can safely delete that file. The e2fsprogs package ships an EVMS plugin for recognizing ext2/3 filesystems, but it is out-of-date with the current version of the EVMS engine. And EVMS ships its own plugin for recognizing ext2/3 filesystems, so the extra one from e2fsprogs isn't necessary. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=383343&aid=815456&group_id=25076 -- Kevin Corry kev...@us... http://evms.sourceforge.net/ |
