On BDA V4.4 OL6 the following symptoms are observed on one node of the cluster, which in this case is Node 5.
1. Running "bdacli disable bdc" fails with an error on Node 5:
scp: /opt/oracle/BDAMammoth/bdaconfig/tmp/bdacli_imghistory.sh: Read-only file system
ERROR: Update imagehistory failed
2. It is observed that on Node 5 where BDD is installed, that /bdd is not accessible.
3. Even a simple command like belong fails on Node 5 because "/" appears to have become a read-only filesystem.
indicates that mdadm crashes and that there are inconsistencies on the '/' and '/boot' partitions.
