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