Symptoms

Probleem

Een SyncIQ-beleid mislukt binnen de eerste vijf minuten na het starten met een fout Snapshots initialization error.
 

Symptomen

Een SyncIQ-beleid mislukt vrijwel onmiddellijk en er wordt een waarschuwing weergegeven die lijkt op het volgende:

policy name: TestSnapshots target: 192.168.117.200) SyncIQ failed to take a snapshot on source cluster. Snapshots initialization error

 

Het volgende wordt vastgelegd in /var/log/messages op het coördinatorknooppunt:

Cause

Oorzaak

De bronhoofdmap die in het SyncIQ-beleid is gedefinieerd, is ingesteld op iets binnen /ifs/.snapshot. Dit is geen ondersteunde configuratie.
 

Controleer het probleem.

In het SyncIQ-beleid is de "source root directory" ingesteld op een /ifs/.snapshot/ directorypad. Bijvoorbeeld:

maw-1# isi sync policies view TestSnapshots
                        ID: d132211dc41614d7332515911c21d1cf
                       Name: TestSnapshots
                       Path: /ifs/.snapshot/testSnap2/data/SyncIQTesting
                     Action: copy

                     Target: 192.168.117.200
                Description: Testing the ability to make a copy SyncIQ policy of /ifs/.snapshot/etc files
            Check Integrity: Yes
                Target Path: /ifs/data
    Target Snapshot Archive: No   
Target Snapshot Pattern: SIQ_%{SrcCluster}_%{PolicyName}_%Y-%m-%d_%H-%M

/var/log/messages rapporteert de volgende fouten:

2015-07-02T10:52:47-06:00 <0.3> maw-1(id1) /boot/kernel.amd64/kernel: [bam_snapshot.c:1487](pid 5271="isi_migrate")(tid=100646) Failing snap_create. Non-head file to snapshot 4 
2015-07-02T10:52:47-06:00 <3.3> maw-1(id1) isi_migrate[5271]: coord[TestSnapshots:1435855951]: Can't create new snapshot (SIQ-d132211dc41614d7332515911c21d1cf-new): snapshot create failed: Invalid argument

Resolution

Gebruik SyncIQ niet voor bestanden binnen /ifs/.snapshot. Er kunnen geen snapshots worden gemaakt op basis van andere snapshots. Volg de best practices van SyncIQ.

Additional Information

Let op: de foutmelding "Failing snap_create. Non-head file to snapshot." Het is niet mogelijk om een snapshot van een snapshot te maken, daarom faalt het beleid.
