[gpfsug-discuss] CCR troubles - CCR vs systemd

[Marc A Kaplan]

Allow me to restate and demonstrate: 
Even if systemd or any explicit kill signals destroy any/all running mmcr* 
and mmsdr* processes,
simply running mmlsconfig will fire up new mmcr* and mmsdr* processes. For 
example:
## I used kill -9 to kill all mmccr, mmsdr, lxtrace, ... processes

[root at n2 gpfs-git]# ps auwx | grep mm
root      9891  0.0  0.0 112640   980 pts/1    S+   12:57   0:00 grep 
--color=auto mm

[root at n2 gpfs-git]# mmlsconfig
Configuration data for cluster madagascar.frozen:
-------------------------------------------------
clusterName madagascar.frozen
   ...
worker1Threads 1022
adminMode central

File systems in cluster madagascar.frozen:
------------------------------------------
/dev/mak
/dev/x1
/dev/yy
/dev/zz

## mmlsconfig "needs" ccr and sdrserv, so if it doesn't see them, it 
restarts them!
