    vmmax2479 Enthusiast

       

      Hello All,

       

       

      I have one ESX server with local storage. Vvhmba0:0:0 has 300+ GB available. trying to create a LUN with 20 GB and getting this message:

       

       

      error during the configuration of the host: failed to update disk partition information. see attached for more details.

            This happens on occasion and I'm not really sure why. You may need to make the filesystem manually from the command line.

             

             

            /usr/sbin/vmkfstools -C vmfs3 vmhba0:0:X -S <vmfs label>

             

             

            You didn't display enough of your partition table in your screenshot to determine what X should be. But if you scroll down it should have type VMFS, or if you do

             

             

             

             

             

            sfdisk -l /dev/sdX  ( non compaq/hp )

             

             

            sfdisk -l /dev/cciss/c0dX ( compaq / hp )

             

             

             

             

             

            You can see which partition has type 'fb'

                This actually looks kinda strange to me, if you look where the blocks start and end, it seems that there is a hole from 935 to 43938 which is where the majority of your drive space is. It looks like you've partitioned it in a way that is likely unrecoverable since you already have 4 primary partitions.

                 

                 

                 

                 

                 

                Did you take the defaults when you installed? Or did you custom modify the partitions?
