QuantaStor Configuration Files
QuantaStor has a series of configuration files that support the platform and make it customizable by our engineering and support team (usually to support new hardware) without requiring code level changes.

- 14 qs_volume_profiles.conf
qs_ceph_defaults.conf
This file contains a series of defaults to be written to the global section of the ceph.conf file when a new cluster is being created.
qs_cloud_providers.conf
QuantaStor supports integration of object storage with a number of public cloud service providers including Amazon S3, Azure Blob, Dropbox, Wasabi and others. This feature is accessible via the Cloud Integration section of the QuantaStor web management interface. This configuration file enables one to add new service providers and locations to the Cloud Integration system.
qs_device_link.conf
This is an internal configuration file that controls how QuantaStor prioritizes device paths generated by udev. The Linux udev system generates links to block devices and stores them in /dev/disk/by-id and other areas under /dev/disk. These links generally contain unique identifiers or serial numbers for the device within the link name so that devices can be referred to via a strong name that will not change between reboots. Some of these links are better than others and this configuration file applies weights to the different paths according to what works best for unique device identification. It should only be edited by OSNexus support and engineering but can be used to hide invalid devices and add support for media with unique udev rules.
qs_io_profiles.conf
When creating or modifying a Storage Pool there's an option to apply a performance tuning profile to the pool so that it operates optimally for specific use cases like Server Virtualization. New profiles can be added to the system via this configuration file.
qs_nvme_initiator.conf
Some NVMeoF system vendors require special options to be applied at the time of NVMeoF connection in order for the device to work optimally with QuantaStor. One common example is customizing the number of IO queues:
--nr-io-queues=8
