    vmkore partition - config

    davis_lambton Enthusiast

      I have just completed my third install of ESX 3.  For every install i always do a custom partition setup.  But i don't remember with my first two installs if i setup the vmkore partition or now.  VDF does not show anything with the first two, but neither does it the 3rd one that i do remember configuring vmkore.

      Is there a way to look @ the vmkore partition and ensure it's there?

          I am having the same problem.  I setup 3 ESX 3.0 servers with custom partition configs and now I am setting up a new 4th 6 months later and don't remember the custom configs - I lost it. 


          Anyone know of a command to view existing partition sizes?


          Thanks in advance.

            login to the COS,

            execute "mount"

            note the device for mountpoint / (in case your first disk isn't /dev/sda)

            something similar to "/dev/sda6 on / type ext3 (rw)"


            execute fdisk /dev/sda (or the disk device from above without the last number)

            then type p

            you get an output similar to the following

            Disk /dev/sda: 72.9 GB, 72999763968 bytes

            255 heads, 63 sectors/track, 8875 cylinders

            Units = cylinders of 16065 * 512 = 8225280 bytes


               Device Boot    Start       End    Blocks   Id  System

            /dev/sda1   *         1        13    104391   83  Linux

            /dev/sda2            14      6387  51199155   fb  Unknown

            /dev/sda3          6388      6648   2096482+  83  Linux

            /dev/sda4          6649      8875  17888377+   f  Win95 Ext'd (LBA)

            /dev/sda5          6649      6909   2096451   83  Linux

            /dev/sda6          6910      7546   5116671   83  Linux

            /dev/sda7          7547      7677   1052226   83  Linux

            /dev/sda8          7678      7746    554211   82  Linux swap

            /dev/sda9          7747      8000   2040223+  83  Linux

            /dev/sda10         8001      8013    104391   fc  Unknown



            after that enter "q" to quit fdisk


            correlate this with the output of mount, example:

            /dev/sda6 on / type ext3 (rw)

            none on /proc type proc (rw)

            none on /dev/pts type devpts (rw,gid=5,mode=620)

            usbdevfs on /proc/bus/usb type usbdevfs (rw)

            /dev/sda1 on /boot type ext3 (rw)

            /dev/sda7 on /home type ext3 (rw)

            none on /dev/shm type tmpfs (rw)

            /dev/sda5 on /usr type ext3 (rw)

            /dev/sda3 on /var type ext3 (rw)

            /dev/sda9 on /var/log type ext3 (rw)



            The unknown partitions are the vmkcore (ID fc) and vmfs3 (ID fb) (if you have one)

              that was it...thanks.

              looks like it creates a 100MB vmkore partition even if you forget to.
