Amazon FSx for Lustre Maintenance Windows

Amazon FSx for Lustre performs routine software patching for the Lustre software it manages. The maintenance window is your opportunity to control what day and time of the week this software patching occurs.

Patching occurs infrequently, typically once every several weeks. Patching should require only a fraction of your 30-minute maintenance window. During these few minutes of time, your file system will be temporarily unavailable.

You choose the maintenance window during file system creation. If you have no time preference, then a 30-minute default window is assigned.

Changing the Maintenance Window of an Existing File System
