Crash Module

|
|
|
============
|
2019-02-27 12:49:47 +00:00
|
|
|
The crash module collects information about daemon crashdumps and stores
|
2018-06-27 22:14:08 +00:00
|
|
|
it in the Ceph cluster for later analysis.
|
|
|
|
|
|
|
|
|
|
Daemon crashdumps are dumped in /var/lib/ceph/crash by default; this can
|
|
|
|
|
be configured with the option 'crash dir'. Crash directories are named by
|
|
|
|
|
time and date and a randomly-generated UUID, and contain a metadata file
|
|
|
|
|
'meta' and a recent log file, with a "crash_id" that is the same.
|
2019-02-27 12:49:47 +00:00
|
|
|
This module allows the metadata about those dumps to be persisted in
|
2018-06-27 22:14:08 +00:00
|
|
|
the monitors' storage.
