Disk Failures

This section describes how to handle a disk failure.

In an FPO deployment model with IBM Storage Scale the restripeOnDiskFailure=yes configuration parameter should be set to yes. When a disk is not functioning, auto recovery enables the disk to start functioning. Auto recovery enlists the help of any node in the cluster to help recover data. This may affect the file system I/O performance on all nodes, because data might have to be copied from a valid disk to recover the disk.
