stratumctl storage-classes create

Create a storage class (bootstrap-admin)

stratumctl storage-classes create <name> [flags]

Examples

stratumctl storage-classes create fast --driver lvm-thin --pool vg_fast
stratumctl storage-classes create replicated --driver ceph-rbd --pool volumes --default --max-iops-limit 16000

Flags

Flag	Type	Default	Description
--default	bool	false	Mark as default for this driver
--default-iops-limit	int	0	IOPS limit a new volume gets when it asks for none
--default-throughput-limit-mbps	int	0	MB/s limit a new volume gets when it asks for none
--description	string		Free-form description
--display-name	string		Human-friendly display name
--driver	string	lvm-thin	Driver (lvm-thin | ceph-rbd)
--max-iops-limit	int	0	The most IOPS a volume of this class may ask for
--max-throughput-limit-mbps	int	0	The most MB/s a volume of this class may ask for
--pool	string		Backend pool name

stratumctl storage-classes delete

Delete a storage class (refused if any volumes/snapshots/images reference it)

stratumctl storage-classes delete <name> [flags]

Examples

stratumctl storage-classes delete fast

stratumctl storage-classes get

Describe a storage class

stratumctl storage-classes get <name> [flags]

Examples

stratumctl storage-classes get replicated
stratumctl storage-classes get replicated --output json

stratumctl storage-classes list

List storage classes

stratumctl storage-classes list [flags]

Examples

stratumctl storage-classes list
stratumctl storage-classes list --output json

stratumctl storage-classes set-qos

Replace a storage class’s per-volume I/O default and maximum (bootstrap-admin)

stratumctl storage-classes set-qos <name> [flags]

Replaces all four QoS fields at once; a flag not passed becomes “none”:

stratumctl storage-classes set-qos replicated --default-iops-limit 3000 --max-iops-limit 16000

Examples

stratumctl storage-classes set-qos replicated --default-iops-limit 3000 --max-iops-limit 16000
stratumctl storage-classes set-qos replicated --default-throughput-limit-mbps 125 --max-throughput-limit-mbps 500

Flags

Flag	Type	Default	Description
--default-iops-limit	int	0	IOPS limit a new volume gets when it asks for none
--default-throughput-limit-mbps	int	0	MB/s limit a new volume gets when it asks for none
--max-iops-limit	int	0	The most IOPS a volume of this class may ask for
--max-throughput-limit-mbps	int	0	The most MB/s a volume of this class may ask for

stratumctl storage-classes stats

Capacity + utilization stats (refreshed every 60s by the pool poller)

stratumctl storage-classes stats <name> [flags]

Examples

stratumctl storage-classes stats replicated
stratumctl storage-classes stats replicated --output json
