About this Webinar
IBM Spectrum Scale webinars are hosted by IBM Spectrum Scale support to

product updates and best practices based on various use cases. This webinar
introduces various concepts and features related to disk lease, node expel,
and node recovery. It explains the mechanism of disk lease, the common
scenarios and causes for node expel, and different phases of node recovery.
It also explains DMS (Deadman Switch) timer which could trigger kernel
panic as a result of lease expiry and hang I/O. This webinar also talks
