Hi all,
I run a Firefly cluster with a MDS server for a while without any problem.
I would like to setup a second one to get a failover server.
To minimize downtime in case of failure, I want the standby server to
replay journal "on the fly". According to documentation, it seems possible.
Here is my config :
[mds]
mds data = /var/lib/ceph/mds/mds.$id
keyring = /var/lib/ceph/mds/mds.$id/mds.$id.keyring
mds cache size = 1000000
debug mds = 0/20
# debug ms = 1
# debug journaler = 20
[mds.0]
host = host6
mds standby replay = true
mds standby for name = 1
[mds.1]
host = host5
Other configs related to MDS are defaults.
mds.1 is my active MDS.
When I start mds.0, after a few minutes, mds.1 is crashing (it was
running for days without any problem).
Dump data is in attached file. If you need objdump of executable, just
tell me but I use the official Debian package one. :)
What could have caused this problem ?
Thank you a lot.
