Increase ExtremeManagement Disk Space

    Hi,

    Just in the process of following this GTAC article about increasing the disk space:

    https://extremeportal.force.com/ExtrArticleDetail?an=000078315

    I have two hard disks associated to the host, as per the screenshot below:

    RackMultipart20180412-10617-1vh8ta1-VM-Disk_inline.png

     


    When I run the script I get the following error:

    ./expandLVM.sh
    WARNING:
    This script will attempt to locate a new virtual drive and add it to
    the current LVM configuration. This script will format the new drive,
    and should only be used in accordance with official instructions
    to increase the size of the hard drive.

    Would you like to proceed? [n]: y

    Starting partition resizing. Start size is 98GB
    Logging to expandLVM.log
    Scanning for new partition sdc
    Scan could not detect new drive sdc, exiting.[/code]
    Any idea why a new sdc partition isn't being found?

    Thanks

    I didn't like to add a 2nd disk so the GTAC provided another method for me (= increase the current disk) and it worked great....

    Hi Ronald,

    Be honest I see that, the length of detail in it and fact in big letters saying it hasn't been tested,l that I took the root of least resistance and went with adding another disk and simply just running the script.

    As it worked great for you, then I'll perhaps give that a go :-)

    Thanks.

    The instruction say the following:

    root@purview-vm.dmqa.enterasys.com:~$ cfdisk
    Note: this will open an application.
    > select the "free disk space" named /sda6
    > Select "New"
    > Select "Logical"
    > Leave the "FS Type" set to "Linux" option 83
    > Select "Write" to save the changes
    > Select "Quit" to exit

    I don't see anything that says:

    "free disk space" named /sda6#



    I do seem to have two disks provisioned for this VM host,which this might be showing, but I only think one is in use, so I don't think this is right.

    Think I perhaps use sbd as mentioned by Seth.

    Here is what 'print free' displayed:

    GNU Parted 2.3
    Using /dev/sda
    Welcome to GNU Parted! Type 'help' to view a list of commands.
    (parted) print free
    Model: VMware Virtual disk (scsi)
    Disk /dev/sda: 107GB
    Sector size (logical/physical): 512B/512B
    Partition Table: msdos
    Number Start End Size Type File system Flags
    32.3kB 1049kB 1016kB Free Space
    1 1049kB 256MB 255MB primary ext2 boot
    256MB 257MB 1048kB Free Space
    2 257MB 107GB 107GB extended
    5 257MB 107GB 107GB logical lvm
    107GB 107GB 1049kB Free Space

    So I run the command below to look at sdb:

    cfdisk /dev/sdb

    And it seemed to show up the expanded space I created, so followed the instructions for this instead.

    So cfdisk /dev/sdb now looks like this:



    The next step of the command is to run this:

    fdisk -l /dev/sda

    And it should then look as follows:

    Device Boot Start End Blocks Id System
    /dev/sda1 * 2048 499711 248832 83 Linux
    /dev/sda2 501758 104857599 52177921 5 Extended
    /dev/sda5 501760 83884031 41691136 8e Linux LVM
    /dev/sda6 83884095 104857599 10486752+ 83 Linux <<< NEW FREE DISK

    But mine looks like this:

    root@NMS.server.online:~$ fdisk -l /dev/sda

    Disk /dev/sda: 107.4 GB, 107374182400 bytes
    255 heads, 63 sectors/track, 13054 cylinders, total 209715200 sectors
    Units = sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0x000bef28
    Device Boot Start End Blocks Id System
    /dev/sda1 * 2048 499711 248832 83 Linux
    /dev/sda2 501758 209713151 104605697 5 Extended
    /dev/sda5 501760 209713151 104605696 8e Linux LVM

    root@NMS.server.online:~$ fdisk -l /dev/sdb
    Disk /dev/sdb: 214.7 GB, 214748364800 bytes
    255 heads, 63 sectors/track, 26108 cylinders, total 419430400 sectors
    Units = sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0x00000000
    Device Boot Start End Blocks Id System
    /dev/sdb1 63 419430399 209715168+ 5 Extended
    /dev/sdb5 126 419430399 209715137 83 Linux

    So my assumption here is that I carry on the using /dev/sdb5 instead of /dev/sda6

    Just wondering if anyone can confirm before I proceed?

    Thanks.

    I decided to take the plunge.... and it worked a treat!

    Thanks for the information and reassurance, really helped.

    One extra thing to note, you might think to take a snapshot just to be safe, but if you do you can't increase the disk space as it gets greyed out... maybe you can increase the disk space then take a snapshot, not sure, but that caught me out a little bit.

    I had to work on another system today with low disk space and once again the method worked great.

    Thanks to whoever tested this and wrote the instructions !!!

    I also used this method because I already had two disks in my VM, and it worked well. Be sure to direct it to expand sdb, not sda. That tripped me up.
