D.5. Configuration
Symptom Resolution
1. After the system has booted, there is a
message on the screen saying that the
configuration file is missing.
2. The node boots, but there is no storage
available on it.
3. There is a hard disk in a node that does not
appear in the available storage.
4. After adding a new drive to a node, some of
the volumes will not mount.
5. After moving a volume from one node to
another, some volumes in the new node will
not mount.
Every node needs to have a node.cfg file on the
USB stick and all the volumes within the node
need to be specified in the vols option. See
Appendix A: Node Configuration for information
about configuring a node.
If the vols specification is correct, this may be
an issue with the amount of RAM in the node.
Check the available RAM to make sure it is
sufficiently provisioned.
6. The node boots from the USB device but DX
Storage fails to start.
7. The node begins to boot but reports a “kernel
panic” error and stops.
This is likely a hardware compatibility issue with
the hardware. Please contact Caringo support
with the details of your hardware setup.
8. Some changes to the node.cfg file disappear
after editing.
If a USB stick is removed from a computer
without unmounting, some changes can be lost.
Use the proper method for your OS to stop and
unmount the USB media before removing it.
9. A node hangs during boot while initializing
ACPI services.
Some hardware presents issues with the ACPI
interface. The solution is to add the argument
“acpi=off” to the syslinux.cfg file on the USB
flash drive for local booting or to the PXE
configuration file for network booting.
10.The DX Storage node boots as having an
unregistered license.
The license file is not in the Caringo directory
on the USB drive, or the licenseFileURL option
in the node or cluster configuration file has not
been properly set.
D.6. Operational Problems
Symptom Resolution
1. A volume device has failed. The node can either be allowed to continue to
run in a degraded state (lowered storage), or
the node may be gracefully shutdown in order
to replace the failed device. The node must be
returned to service within 14 days.
2. A node has failed. If a node fails but the volume storage devices
are still good, you may repair the hardware
and return it to service within 14 days. If it
has been more than 14 days, see the Volume
Management section for information on volume
handling.
