glusterfs.git/tests/basic/gfapi/glfs_sysrq.c, branch v3.12.5 GlusterFS is a distributed file-system capable of scaling to several petabytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. gfapi: add API to trigger events for debugging and troubleshooting 2017-01-19T18:44:22+00:00 Niels de Vos ndevos@redhat.com 2017-01-06T11:49:32+00:00 d93a6691538270aefe7703e8f8d7c822f53528e5 Introduce glfs_sysrq() as a generic API for triggering debug and troubleshoot events. This interface will be used by the feature to get statedumps for applications using libgfapi. The current events that can be requested through this API are: - 'h'elp: log a mesage with all supported events - 's'tatedump: trigger a statedump for the passed glfs_t In future, this API can be used by a CLI to trigger statedumps from storage servers. At the moment it is limited to take statedumps, but it is extensible to set the log-level, clear caches, force reconnects and much more.

Introduce glfs_sysrq() as a generic API for triggering debug and
troubleshoot events. This interface will be used by the feature to get
statedumps for applications using libgfapi.

The current events that can be requested through this API are:
 - 'h'elp: log a mesage with all supported events
 - 's'tatedump: trigger a statedump for the passed glfs_t

In future, this API can be used by a CLI to trigger statedumps from
storage servers. At the moment it is limited to take statedumps, but it
is extensible to set the log-level, clear caches, force reconnects and
