Symptoms

En ugyldig fil med navnet "ls" blev oprettet i /var/lib/docker/devicemapper/metadata ved en fejl.

SP går ind i en rullende genstart med eVE-fejl i /EMC/C4Core/log/start_c4.log (eller /mnt/ssdroot/EMC/C4Core/log/start_c4.log, hvis SP er i servicetilstand):

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"

 

Cause

I henhold til /EMC/CEM/log/eVE/eVE_startup.log på SP kører Dockeren ikke:

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

Ifølge /var/log/messages mislykkedes Docker-tjenesten, fordi den ikke kunne indlæse enhedsfilen "ls":

2017-08-07T21:41:09+00:00 self docker[18109]: time="2017-08-07T21:41:09.996387324Z" level=error msg="[graphdriver] prior storage driver \"devicemapper\" failed: devmapper: Failed to load device files:Error looking up device ls:Unknown device ls"
2017-08-07T21:41:09+00:00 self docker[18109]: time="2017-08-07T21:41:09.996422502Z" level=fatal msg="Error starting daemon: error initializing graphdriver: devmapper: Failed to load device files:Error looking up device ls:Unknown device ls"
2017-08-07T21:41:10+00:00 self systemd[1]: docker.service: main process exited, code=exited, status=1/FAILURE

 

Resolution

  1. Fjern den problematiske fil i /var/lib/docker/devicemapper/metadata:

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

  2. Ryd startredningstælleren:

    svc_rescue_state -c

  3. Genstart SP:

    svc_shutdown -r
Bemærk: En SP-genafbildning kan også løse dette problem.
