Adding EBS volumes for use in ASM

  • Updated
  • Products: FlashGrid Server on AWS

When adding new disks make sure that each disk group has disks of the same size.

  1. Create and attach new volumes to the AWS instance. Attach the volumes using disk names xvdba through xvdbz - these disks will be automatically available for use in ASM.

  2. Confirm FlashGrid names of the new disks, e.g. myhostname.xvdbb

    [fg@myhostname ~] $ flashgrid-node

    If the new disks are not listed then check that the corresponding devices (e.g. /dev/xvdbb) are visible in the OS. If they are visible in the OS then run # flashgrid-node reload-config

     and check output of flashgrid-cluster drives again. If they are not visible in the OS then double-check that you have attached them with correct device names.

  3. Add the new disks to an existing disk group (or create a new disk group). Example:

    [fg@myhostname ~] $ flashgrid-dg add-disks -G MYDG -d /dev/flashgrid/myhostname.xvdb[a-c]
