lbcli update qos-policy (2.3.16 and above)

--help

-h

bool

Help for qos-policy.

--description

string

Policy description.

--global

bool

Sets the policy as global (available for use by all projects/volumes in the cluster).

Note: The Lightbits 2.3.16 release does not support updating the value of global from true to false, and vice versa.

--name

string

Policy name.

--projects

stringSlice

Specify the projects that can have access to this policy.

Note: Either specify the policy as Global (global=true), or explicitly name specific projects that can use this policy.

--pure-iops

bool

When true, each IO costs 1 IOPS regardless of size (only valid with iops/iops-per-gb types).

--read-limit

uint32

Specify the rate limit for read operations.

The units of this field are defined by the rate limit Type field.

Note: A 0 value encodes unlimited.

--type

string

Limit type (iops, bw, ips-per-gb) (Required).

• iops: Volume read and write bandwidth limits, specified in units of IOPs. The granularity increases by 256 IOPs each time. For example, 400 IOPs would be rounded up to 512 IOPs. Note that the IOPs limit assumes a 4 KB block size for rate calculations.

• bw: Volume read and write bandwith limits, specified in units of MB/s. The granularity must be in full MB/s.

• iops-per-gb: Volume read and write bandwidth, specified in limits in IOPs per GB of volume size. For example: If read-limit=30, write-limit=20 and volume size is 7Tib, the actual limits for this volume would be: read 210,000 IOPs, write 140,000 IOPs. Note that the volume size will be rounded down if it is not a whole GB.

--uuid

string

Policy UUID.

--write-limit

uint32

Specify the rate limit for write operations.

The units of this field are defined by the rate limit Type field.

Note: A 0 value encodes unlimited.
