Symptoms

  • Distribuere proxy-versjon 19.3 ved hjelp av proxy deployment manager.


  • Når du bruker proxy-versjon 19.3, mislykkes tilfeldige sikkerhetskopieringer av VM-bilder som viser feilmeldingene nedenfor: 
    [VcbImageBackupAssistThread]  ERROR: <0237> Cannot create thread (11) Resource temporarily unavailable
avvcbimage Info <43574>: vcApiVersion 6.5
avvcbimage Info <43575>: VSphereHTTP::vcVersion65 will be true
avvcbimage Info <42137>: job type = 4
.
avvcbimage Info <16041>: VDDK:VixDiskLib: Advanced transport plugin /usr/lib/vmware-vix-disklib/lib64/libdiskLibPlugin.so was successfully loaded into vixDiskLib.
avvcbimage Info <16041>: VDDK:VixDiskLib: Enabling advanced transport modes.
[VcbImageBackupAssistThread]  ERROR: <0001> threadimpl::runthread Exception Resource temporarily unavailable
avvcbimage Info <9772>: Starting graceful (staged) termination, MCS cancel (wrap-up stage)

Cause

  • Antall proxy-oppgaver overskred verdien (512) som er angitt for "TasksMax", selv om verdien er satt til "infinity" i filen "/etc/systemd/system/multi-user.target.wants/avagent.service" som nedenfor: 
    <Proxy_Name>:~ # less /etc/systemd/system/multi-user.target.wants/avagent.service
.
[Service]
ExecStart=/etc/init.d/avagent start
ExecStop=/etc/init.d/avagent stop
KillMode=process
Restart=on-abort
RemainAfterExit=yes
TasksMax=infinity
  • Også når du sjekker oppgavetelling fra Service "vami-sfcb.service", viser den riktig oppgavetelling som nedenfor: 
    <Proxy_Name>:~ # systemctl status vami-sfcb.service
  vami-sfcb.service - LSB: Small Footprint CIM Broker Service
   Loaded: loaded (/etc/init.d/vami-sfcb; disabled; vendor preset: disabled)
   Active: active (running) since <DAY> <yyyy-mm-dd hh:mm:ss UTC; # days ago
     Docs: man:systemd-sysv-generator(8)
    Tasks: 16 (limit: 512)
   CGroup: /system.slice/vami-sfcb.service
              6873 /opt/vmware/sbin/vami-sfcbd -d
              6878 /opt/vmware/sbin/vami-sfcbd -d
              6882 /opt/vmware/sbin/vami-sfcbd -d
              6883 /opt/vmware/sbin/vami-sfcbd -d
              6892 /opt/vmware/sbin/vami-sfcbd -d
              6901 /opt/vmware/sbin/vami-sfcbd -d
             11366 /usr/local/avamarclient/bin/avagent.bin --listenport=28009...
  • Men når du sjekker oppgavetellingsnummer fra "avagent.service" , viser den "0" -verdien, noe som betyr at den ikke teller oppgaver riktig som nedenfor: 
    <Proxy_Name>:~ # systemctl status avagent.service
  avagent.service - Avamar Unix backup/restore agent (avagent)
   Loaded: loaded (/usr/lib/systemd/system/avagent.service; enabled; vendor preset: disabled)
   Active: active (exited) since <Day> <yyyy-mm-dd hh:mm:ss UTC; # ago
 Main PID: 1286 (code=exited, status=0/SUCCESS)
    Tasks: 0
   CGroup: /system.slice/avagent.service
             1476 /usr/local/avamarclient/bin/avagent.bin --listenport=28009 ...

Resolution

  1. I proxyen må du kontrollere at verdien "TasksMax" er satt til "infinity" i filen "/etc/systemd/system/multi-user.target.wants/avagent.service" som nedenfor: 
    <Proxy_Name>:~ # less /etc/systemd/system/multi-user.target.wants/avagent.service
.
[Service]
ExecStart=/etc/init.d/avagent start
ExecStop=/etc/init.d/avagent stop
KillMode=process
Restart=on-abort
RemainAfterExit=yes
TasksMax=infinity
  2. Aktiver tjenesten «vami-sfcb» på proxyen som vist nedenfor: 
    <Proxy_Name>:~ # systemctl enable vami-sfcb
Synchronizing state of vami-sfcb.service with SysV init with /usr/lib/systemd/systemd-sysv-install...
Executing /usr/lib/systemd/systemd-sysv-install enable vami-sfcb
Created symlink from /etc/systemd/system/multi-user.target.wants/vami-sfcb.service to /usr/lib/systemd/system/vami-sfcb.service.
  3. Start proxyen på nytt ved å bruke kommandoen "reboot".
  4. Kontroller at tjenesten "avagent.service" viser riktig oppgavetelling og ikke null som nedenfor: 
    <Proxy_Name>:~ # systemctl status avagent.service
  avagent.service - Avamar Unix backup/restore agent (avagent)
   Loaded: loaded (/usr/lib/systemd/system/avagent.service; enabled; vendor preset: disabled)
   Active: active (exited) since <Day> <yyyy-mm-dd hh:mm:ss UTC; # ago
 Main PID: 1286 (code=exited, status=0/SUCCESS)
    Tasks: 16
   CGroup: /system.slice/avagent.service
             1476 /usr/local/avamarclient/bin/avagent.bin --listenport=28009 ...
