ost --update_client --name <OST Client Hostname> --mode <auto | passthrough | dedupe>

Description

Updates the attributes of an OST client (OST client name and mode). The OST client modes are auto, passthrough, and dedupe.However, the OST client operating mode depends upon how it is configured in QoreStor.

  • Auto —Auto mode in QoreStor functions the same as Dedupe mode.
  • Passthrough — The OST client passes all data to QoreStor for dedupe processing. This is also known as “server-side dedupe”.
  • Dedupe — The OST client processes hashing on the data. This is also known as “source-side dedupe” and is the default mode. Source-side depuplication is resource intensive. On machines with less than four cores, or on 32-bit machines, performance may be reduced.

Syntax

ost --update_client --name <OST Client Hostname> --mode <auto|passthrough|dedupe>

Where

--name   Hostname of client
--mode   OST modes (auto, dedupe, passthrough)

NOTE: You may be able to force writes for OST clients running in the Passthrough mode using the QoreStor CLI mode --dedupecommand. The change in OST client mode is effective on the next backup operation when you are using Veritas NetBackup. (If you are using Veritas Backup Exec, you will need to restart this service for it to recognize that a new mode has been configured.)

Result

OST client updated successfully.

ost --limit --speed <<num><KBps | MBps | GBps | default> --target <ip address | hostname>

Description

Limits the bandwidth consumed by OST (OpenStorage Technology) for a system you define by IP address or hostname (--target), by which you define the speed in kilobytes/second (KBps), megabytes/second (MBps), gigabytes/second (GBps), or an unlimited bandwidth (default).

Syntax

ost --limit --speed <<num><KBps|MBps|GBps> | default> --target <ip address | hostname>

Where

--speed    OST speed limit (eg. 10MBps).
--target   DR replication target name or IP address.

Result

Successfully updated OST bandwidth limit for acmesys-49 to 10 MBps.

ost --partial_images --containerid <Container id> [--delete <Partial image path>] [--timeout <> 0>]

Description

Lists or cleans up partial images.

  • Container id — ID of container.
  • Partial image path — OST partial image path to delete.
  • Timeout — Maximum timeout (in seconds) to list partial images.

Syntax

ost --partial_images --containerid <Container id> [--delete <Partial image path>] [--timeout <> 0>]

Where

--containerid   Container ID.
--delete        OST partial image path to delete
--timeout       Maximum timeout(in seconds) to list partial images.
