If a bandwidth reservation is not created for a policy, the bandwidth reserve is applied. The bandwidth reserve is specified as a global configuration parameter, as a percentage of the global configured bandwidth or an absolute limit in bits per second.
Note: If a bandwidth reservation is not configured in OneFS 8.2 for a specific policy, the default bandwidth reserve is 1% of the global configured bandwidth. The default is set at this level to encourage administrators to configure the bandwidth reservation per policy. For clusters upgrading from a previous release to OneFS 8.2, note that any existing policies default to the 1% bandwidth reservation, assuming a global bandwidth reserve is not configured.
In the case where a bandwidth reservation is not configured for a policy, the bandwidth reserve is applied if sufficient bandwidth is not available. To configure a bandwidth reservation percentage, use the following command:
isi sync settings modify --bandwidth-reservation-reserve-percentage=[% of global bandwidth reservation]
To configure a bandwidth reservation in bits per second rather than a percentage, use the following command:
isi sync settings modify --bandwidth-reservation-reserve-absolute=[kb/s]
Further, to clear a configured bandwidth reserve, use the following command:
isi sync settings modify --clear-bandwidth-reservation-reserve
