Offboard storage in HA environments

If you choose to move the /store file system in a high-availability (HA) environment, the /store file system is not replicated by using Disk Replication Block Device.

If you move the /store/ariel file system to an offboard storage device and maintain the /store file system on local disk, the /store file system is synchronized with the secondary HA host. By default, when your environment is configured for HA, Disk Replication Block Device is enabled.

If you are using HA and you move a file system other than /store or /store/ariel to a multipath offboard storage solution, you must stop multipathd before upgrading QRadar.
