      Limitations

Limitations

Following are the functional limitations due to external factors.

Table: Limitation description and workaround

Description

Workaround

Storage expansion by adding disks to the node (scale up) is not supported. (4046551)

Note:

This limitation is applicable to Direct Attached Storage (DAS) only.

Reboot the entire cluster after manually adding disks to a node. Then add new disks to the disk group manually when the cluster comes up.

When DataReplication Custom Resource (CR) is configured for a namespace, adding a new PVC to this namespace can result in data corruption. (4052704)

If you want to add a new PVC to an existing namespace

  1. Stop data replication by setting ReplicationState attribute to 'stop' and RemoteClusterDetails:Force attribute to 'true' in DataReplication CR.

  2. Add the new PVC and verify whether it is visible in DataReplication CR.

  3. Reset RemoteClusterDetails:Force as 'false' in DataReplication and start data replication by resetting ReplicationState to 'start'.

If data replication is configured and Volume is mounted only on a slave node, Volume resize operation (vxresize) fails with an error message 'file system is not mounted'. (4047378)

None

When DataReplication for DR is configured for a Galera 3 pod cluster, VVR performs a full synchronization instead of a smartsync (4051639)

None. Wait for initial full synchronization to complete before triggering the migration.

Remove node is not supported for InfoScale on OpenShift or Kubernetes. (4044647)

To remove node, contact Arctera Technical support.
