Parameters
Parameter |
Description |
Value |
|---|---|---|
| max_volume_all_delay=? | Maximum latency of layer-1 cache I/O flushing. | The value must be an integer from 0 to 2,147,483,647, expressed in ms. |
| max_stripe_all_delay=? | Maximum latency of layer-2 cache I/O flushing. | The value must be an integer from 0 to 2,147,483,647, expressed in ms. |
| max_volume_io_delay=? | Maximum latency of layer-1 single I/O cache flushing. | The value must be an integer from 0 to 2,147,483,647, expressed in ms. |
| max_stripe_io_delay=? | Maximum latency of layer-2 single I/O cache flushing. | The value must be an integer from 0 to 2,147,483,647, expressed in ms. |
Example
Changing the maximum latency of layer-1 I/O cache flushing, layer-2 cache flushing, layer-1 single I/O cache flushing, and layer-2 single I/O cache flushing to 10 ms, 20 ms, 1 ms, and 2 ms respectively.
