sounds like a storage configuration issue: 2016-03-09T08:52:51.791-0500 [initandlisten] exception in initAndListen: 13516 couldn't open file /var/lib/mongodb/data/journal/j._0 for writing errno:1 Operation not permitted, terminating What is a the PV and PVC like? The message points Operation Not Permitted error. The underlying storage looks the issue. Please provide the jaml for the PV the PVC, and the pod. Also what is the the backing storage ? Note that our knowledge base suggests to fiddle with service accounts to work around this: https://access.redhat.com/solutions/2194761 So as Jan mentioned in comment#5 this: https://access.redhat.com/solutions/2194761 There are two more options: 1) Use a block device as the bases for storage backend (Ceph, iSCSI, AWS EBC, GCE PD, not NFS) and enable automatic fsGroup assignment - to enable automatic fsGroup assignment: oc get -o json pod | grep scc # get scc name oc edit <scc name> #set fsGroup type to MustRunAs instead of RunAsAny more information about fsGroup: https://docs.openshift.org/latest/install_config/persistent_storage/pod_security_context.html#fsgroup 2) Use NFS as a back end but change the group ownership of the target directory to some group (eg 12345) then add that group as a supplemental group to the pod either by editing the template file or editing the dc. we are working on a feature to enable adding it to the PV: https://github.com/kubernetes/kubernetes/pull/20490 closing this. Jaspreet please reopen if you feel you issues have not been addressed. |
Description of problem: When creating application using mongodb-persistent-template.json or postgresql-persistent-template.json, pods keep restarting with errors Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Create an application using mongodb-persistent template 2. Create a persistent volume claim for the application bounded to a persistent volume 3. The pod gets created however it keeps on restarting.
