mc support perf drive

The mc support perf drive command measures the read/write speed of the drives in a cluster.

The command displays results in a terminal user interface (TUI) with a spinner during testing and a tabular output showing per-server statistics.

Use this command to identify potential drive performance bottlenecks in your deployment.

Syntax

Example Syntax

The command has the following syntax:

mc [GLOBALFLAGS] support perf drive  \
                 ALIAS               \
                 [--verbose, -v]     \
                 [--airgap]

Brackets [] indicate optional parameters.
Parameters sharing a line are mutually dependent.
Parameters separated using the pipe | operator are mutually exclusive.

Copy the example to a text editor and modify as needed before running the command in the terminal/shell.

Parameters

ALIAS

Required

The alias of the AIStor deployment.

--airgap

Optional

Use in environments without network access to SUBNET (for example, airgapped, firewalled, or similar configuration).

If the deployment is airgapped, but the local device where you are using the AIStor Client has network access, you do not need to use the --airgap flag.

--verbose, -v

Optional

Show per-drive statistics in the output.

By default, the command displays a consolidated view with per-server statistics showing the number of drives and aggregated read/write performance (average and min-max range). When --verbose is enabled, the output shows individual statistics for each drive path on each server.

Global flags

This command supports any of the global flags.

Examples

Test speed of all drives on all nodes

Run drive read/write performance measurements on all drives on all nodes for a cluster with alias myaistor.

mc support perf drive myaistor

Test drive speed with per-drive statistics

Run drive read/write performance measurements showing individual statistics for each drive path.

mc support perf drive myaistor --verbose
