Supported File systems

Host Filesystems

StorageOS will automatically use /var/lib/storageos on each host as a base directory for storing configuration and blob files. Supported host filesystem types are ext4 and xfs. If you require a specific filesystem please contact StorageOS.

Persistent Volume Filesystems

StorageOS provides a block device on which a file system can be created. The creation of the filesystem is either handled by StorageOS or by Kubernetes which affects what filesystems can be created.

CSI Driver

When using StorageOS with the CSI driver, StorageOS is responsible for running mkfs against the block device that pods mount. StorageOS is able to create ext2, ext3, ext4 and xfs file systems.

Native Driver

When using StorageOS with the native driver, Kubernetes is responsible for running mkfs against the StorageOS block device. This means that any file system that Kubernetes can create can be used.

However if the StorageOS CLI is used to mount a device then an ext4 filesystem will be created by default.
