expand-storage-pool-not-managed-by-px

If you are running Portworx in an environment where you need or want to manually resize a pool using drives that are not managed by Portworx, then follow these steps:

Add drives

1. Identify a storage pool that's running low on capacity.

2. Add drives to your node that are similar in size, type, and performance to the drives already in the pool you need to expand.

3. Add the drive by running the pxctl service drive add command with the following options:

   • The --drive flag followed by the name of the drive you want to add.
   • The --operation start flag.

   pxctl sv drive add --drive /dev/sde --operation start

   Adding drives may make storage offline for the duration of the operation.
   Are you sure you want to proceed ? (Y/N): y
   Drive add done: Storage rebalance is in progress

   After adding the drive, Portworx starts restriping the pool to include the new drive.

4. Monitor the drive add operation status by entering the pxctl service drive add command, specifying the following:

   • The --drive flag and the name of the drive you added
   • The --operation status flag

   pxctl service drive add --drive /dev/sde --operation status

   When the status shows as Drive /dev/sde already in use by PX., storage will be brought online automatically when this operation completes.

Expand a pool size to consume the added drive capacity

Follow the instructions in this section to expand the capacity of your storage pool and make use of the available capacity from added drives or existing drives that are not managed by Portworx:

1. Run the following command to identify a storage pool that's in need of expansion:

   pxctl service pool show

2. Resize your drive and drive partition, if required.

3. On the node containing your target drive, enter the pxctl service pool update command, specifying the --resize option and the ID of the pool you want to resize:

   pxctl service pool update --resize <pool-id>

   Pool properties updated
