Supported File System

Host Filesystems

Ondat 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 Ondat.

Persistent Volume Filesystems

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

CSI Driver

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