# rbd_mirror_helpers.sh - shared rbd-mirror daemon helper functions
|
|
#
|
|
# The scripts starts two ("local" and "remote") clusters using mstart.sh script,
|
|
# creates a temporary directory, used for cluster configs, daemon logs, admin
|
|
# socket, temporary files, and launches rbd-mirror daemon.
|
|
#
|
|
# There are several env variables useful when troubleshooting a test failure:
|
|
#
|
|
# RBD_MIRROR_NOCLEANUP - if not empty, don't run the cleanup (stop processes,
|
|
# destroy the clusters and remove the temp directory)
|
|
# on exit, so it is possible to check the test state
|
|
# after failure.
|
|
# RBD_MIRROR_TEMDIR - use this path when creating the temporary directory
|
|
# (should not exist) instead of running mktemp(1).
|
|
# RBD_MIRROR_ARGS - use this to pass additional arguments to started
|
|
# rbd-mirror daemons.
|
|
# RBD_MIRROR_VARGS - use this to pass additional arguments to vstart.sh
|
|
# when starting clusters.
|
|
#
|
|
# The cleanup can be done as a separate step, running the script with
|
|
# `cleanup ${RBD_MIRROR_TEMDIR}' arguments.
|
|
#
|
|
# Note, as other workunits tests, rbd_mirror.sh expects to find ceph binaries
|
|
# in PATH.
|
|
#
|
|
# Thus a typical troubleshooting session:
|
|
#
|
|
# From Ceph src dir (CEPH_SRC_PATH), start the test in NOCLEANUP mode and with
|
|
# TEMPDIR pointing to a known location:
|
|
#
|
|
# cd $CEPH_SRC_PATH
|
|
# PATH=$CEPH_SRC_PATH:$PATH
|
|
# RBD_MIRROR_NOCLEANUP=1 RBD_MIRROR_TEMDIR=/tmp/tmp.rbd_mirror \
|
|
# ../qa/workunits/rbd/rbd_mirror.sh
|
|
#
|
|
# After the test failure cd to TEMPDIR and check the current state:
|
|
#
|
|
# cd /tmp/tmp.rbd_mirror
|
|
# ls
|
|
# less rbd-mirror.cluster1_daemon.$pid.log
|
|
# ceph --cluster cluster1 -s
|
|
# ceph --cluster cluster1 -s
|
|
# rbd --cluster cluster2 -p mirror ls
|
|
# rbd --cluster cluster2 -p mirror journal status --image test
|
|
# ceph --admin-daemon rbd-mirror.cluster1_daemon.cluster1.$pid.asok help
|
|
# ...
|
|
#
|
|
# Also you can execute commands (functions) from the script:
|
|
#
|
|
# cd $CEPH_SRC_PATH
|
|
# export RBD_MIRROR_TEMDIR=/tmp/tmp.rbd_mirror
|
|
# ../qa/workunits/rbd/rbd_mirror.sh status
|
|
# ../qa/workunits/rbd/rbd_mirror.sh stop_mirror cluster1
|
|
# ../qa/workunits/rbd/rbd_mirror.sh start_mirror cluster2
|
|
# ../qa/workunits/rbd/rbd_mirror.sh flush cluster2
|
|
# ...
|
|
#
|
|
# Eventually, run the cleanup:
|
|
#
|
|
# cd $CEPH_SRC_PATH
|
|
# RBD_MIRROR_TEMDIR=/tmp/tmp.rbd_mirror \
|
|
# ../qa/workunits/rbd/rbd_mirror.sh cleanup
