Dell Unity: SP Rolling Reboot due for eVE failure

Er is per ongeluk een ongeldig bestand met de naam "ls" gemaakt in /var/lib/docker/devicemapper/metadata.

De SP voert een doorlopende herstart in met eVE-fouten in /EMC/C4Core/log/start_c4.log (of /mnt/ssdroot/EMC/C4Core/log/start_c4.log als de SP in servicemodus is):

Mon Aug  7 21:51:41 UTC 2017 CF: iwd: fully started in 0 seconds
Mon Aug  7 21:54:05 UTC 2017 CF: HA: eVE: Error: job cf.eVE stopped
Mon Aug  7 21:54:05 UTC 2017 CF: HA: eVE: stopping
Mon Aug  7 21:54:06 UTC 2017 CF: HA: eVE: Error: failed to stop eVE
Mon Aug  7 21:54:11 UTC 2017 c4_shutdown.sh: called with "-f"

Volgens /EMC/CEM/log/eVE/eVE_startup.log op de SP wordt de Docker niet uitgevoerd:

Mon Aug  7 21:49:05 2017 /EMC/Platform/bin/eVE.pl: Cannot proceed. Docker service is not running
Mon Aug  7 21:49:05 2017 /EMC/Platform/bin/eVE.pl: Cannot proceed. Docker service is not running
Mon Aug  7 21:49:06 2017 /EMC/Platform/bin/eVE.pl: Cannot proceed. Docker service is not running

Volgens /var/log/messages is de Docker-service mislukt omdat het apparaatbestand "ls" niet kon worden geladen:

2017-08-07T21:41:10+00:00 self systemd[1]: docker.service: main process exited, code=exited, status=1/FAILURE

1. Verwijder het problematische bestand in /var/lib/docker/devicemapper/metadata:

   rm -f /var/lib/docker/devicemapper/metadata/ls

2. Wis de teller voor opstarten:

   svc_rescue_state -c

3. Start de SP opnieuw op:

   svc_shutdown -r
