Common issues: Software configuration - unable to execute command

Possible error messages

• Unable to execute command

Resolution

During the node setup phase, CycleCloud uses Chef to configure services and applications on the nodes. Chef invokes native OS commands to do this configuration.

For example, Chef might try to create a mount point and mount a NAS to a cluster node:

mkdir -p /data
mount -t nfs 10.0.1.5:/exports/data /data

These commands can fail for many reasons, which triggers a Chef error. In version 7.9 and later, CycleCloud shows the command that failed, along with the STDOUT and STDERR that contain the error message.

• Review the command that Chef runs and check for syntax errors. If the command comes from a custom Chef recipe or cookbook, fix the error and re-upload the project.
• Sign in to the node that has the error and try running the command as the admin or root user.
• Using mount as an example, if the command is failing, troubleshoot the mounting error by running the command manually and diagnosing the root cause, such as an incorrect server host/IP or export path.
