6.9.5 Storage Management
January 28th, 2026 BEAR provides a set of simple but powerful tools for managing physical disks and filesystems. However, this functionality is intentionally limited to provide only the tools and option necessary for application hosting.
The features provided by BEAR for physical storage management are shown below.

| Filesystem |
XFS |
BEAR uses the XFS filesystem as a high performance enterprise-grade file system throughout. |
| RAID |
RAID level 0, 1, and 10 |
RAID is entirely optional but if desired three levels are provided to provide enhanced volume size and throughput; fault tolerance and redundancy; or both. |
| Log devices |
Dedicated or shared |
Binary write logs provide additional performance and fault resilience. By default, the XFS write log is part of the file system on the same disk. Write always hit the log first before being written out to the file system proper. A dedicated physical device (ideally faster than the devices that make up the file system) can greatly improve throughput on high IO applications. |
| Filesystem replace |
Overwrite or Preserve |
An existing filesystem can be replaced with a larger (or small) filesystem with the original data preserved. |
| Defragment |
Zero downtime |
Although less of an issue with SSD drives, large HDD backed applications may benefit from online background defragmentation. |
| Repair RAID |
RAID levels 1 and 10 |
A matching spare device can replace a failed RAID device. Zero downtime hot swap repair is dependent on hardware. |
| Secure disk wipe |
British HMG Infosec standards |
Disks can be erased instantly (insecure) or using one of two highly secure standards to zeroise every sector on the disk to the strictest security standards. |
| Move disk |
XFS only |
Attached disks with XFS partitions can be mounted either temporarily or permanently. They may also be mounted full read-write or read-only as desired. This allows easy migration of application deployments to new hardware. |
In most cases, an application that has specific storage requirements will provide detailed guidance on the recommended configuration.
