17. Troubleshooting¶
Robin CNS provides a number of native tools and commands for an administrator to utilize in order troubleshoot their Robin cluster and/or report issues. These tools vary in their use case but provide enough information to provide insight as to why as the cluster is not functioning as intended or the reason for unexpected failures. As a result, they should be the go-to utilities when debugging potential issues and their outputs should be sent alongside any bug reports filed to Robin. Each tool has been described in their respective sections below.
Alongside the aforementioned tools for administrators, Robin CNS also provides more granular commands for individual users to track the progress of
their executed operations and determine reasons for their failure. These operations are referred to as jobs and are identified by a unique ID.
17.1. Listing all jobs¶
Robin stores all jobs that have occurred during a cluster’s lifespan. To view these jobs alongside details such as their start time, state etc. issue the following command:
# robin job list --verbose
--ignoredeps
--noarchived
--nopurged
--states <states>
--failed
--nocolor
--page_size <size>
--page_num <num>
--total
--all
--app <app_name>
--k8sapp <k8sapp_name>
--vnode <vnode_name>
--node <node_name>
--disk <disk_wwn>
--json
|
Show complete job information instead of truncating it for display purposes. |
|
Do not show child jobs |
|
Do not show archived jobs |
|
Do not show purged jobs |
|
Filter jobs based on states. Choose one or more from: active, failed, succeeded, archived, purged |
|
Show only jobs which have failed |
|
Show uncolored output |
|
Number of jobs that should be displayed for each page |
|
Page number to start displaying jobs from (starting index 1) |
|
Return the total number of qualified root jobs |
|
Display all jobs associated with a specific application. Note this option must be used in conjunction with the |
|
Filter jobs based on specified application |
|
Filter jobs based on specified K8s/Helm registered application name |
|
Filter jobs based on specified Vnode name |
|
Filter jobs based on specified physical node name |
|
Filter jobs based on specified disk WWN |
|
Display output in JSON format |

17.3. Log Collection¶
During any cluster wide failure or unexpected negative scenarios that affect multiple services, logs from all the system components will be needed by Robin in order to debug the issue properly. However sometimes given the scope of the issue, only a subsection of logs need to be collected. This granularity is available but it is highly recommended to always send the complete set of logs when filing a bug report with Robin. Available age-based filtering helps in reducing storage footprint. Robin supports uploading logs to the following destinations:
|
Used to store collected logs in Robin backed storage |
|
Used to store collected logs in NFS. |
|
Used to store collected logs in Amazon S3 |
|
Used to store collected logs in a given remote location |
|
Used to store collected logs to GCS bucket.(only for GCS repos) |
17.3.1. Storing logs using Robin Storage¶
Logs collected by Robin can be stored on a volume created on the local cluster, with the following command:
# robin log collect robin-storage <rpool>
--nodes <nodes>
--dest-path <dest_path>
--size <size>
--media <media>
--age <age>
|
Name of the resource pool name to use. |
|
Comma separated list of nodes from which to collect. The default is to collect all |
|
Destination path where log files will be copied |
|
Size of the storage volume for the log collect. The default is 250GB |
|

|
Collects log based on age. Valid options are s (sec), m (min), h (hrs), d (days), Mo (month) and y (years) For example 10m represents 10 minutes. |
Example:
# robin log collect robin-storage default --wait
Job: 123 Name: LogCollect State: PROCESSED Error: 0
Job: 123 Name: LogCollect State: WAITING Error: 0
Job: 123 Name: LogCollect State: COMPLETED Error: 0
17.3.2. Storing logs using NFS¶
Logs collected by Robin can be stored on a NFS share, with the following command:
# robin log collect nfs <nfs_share>

|
Comma separated list of nodes from which to collect. The default is to collect all |
|
Access Key for the respective user with access to the specified S3 bucket. |
|
Secret Key for the respective user with access to the specified S3 bucket. |
|
Collects log based on age. Valid options are s (sec), m (min), h (hrs), d (days), Mo (month) and y (years) For example 10m represents 10 minutes. |

# robin log collect ssh <dest>
--nodes <nodes>
--password <password>
--age <age>
|
Destination path where the log files will be copied to. The path should be in the form of ‘<user>@<hostname|IP>:<path>’ |
|
Comma separated list of nodes from which to collect. The default is to collect all |
|
Provide a password on the command line instead of via a prompt |
|
Collects log based on age. Valid options are s (sec), m (min), h (hrs), d (days), Mo (month) and y (years) For example 10m represents 10 minutes. |

Job: 129 Name: LogCollect State: COMPLETED Error: 0
17.3.5. Storing logs on Google Cloud Storage¶
You can backup Robin logs to the Google Cloud Storage (GCS) repo. To back up, you must register a GCS repo on Robin CNS. For more information, see here
robin log collect repo
--nodes <NODES>
--repo_name <REPO_NAME>
--dir_path <DIR_PATH>
--wait
--template <TEMPLATE>
--age <AGE>
--collect-storage-libs
|
This is a comma separated list of nodes from which to collect, default is to collect all. |
|
Select gcs repo from ‘robin repo list’. First register using ‘robin repo register’ |
|
Directory name where log files will be copied inside bucket.(No need to create dir in bucket.) |
|
Wait for the command to finish. |
|
Provide template name or template path. |
|
Collects log based on age. Valid options are s(sec),m(min),h(hrs),d(days),Mo(month) y(years) and all. Example: Use 10m for 10 minutes. Default option is to collect logs of last 3 days |
|
Option to enable collection of files under lib, lib64 and bin for storage |
Example:
[robinmaster@master ~]# robin log collect repo --repo_name robin-repo --wait Job: 235 Name: LogCollect State: PROCESSED Error: 0 Job: 235 Name: LogCollect State: WAITING Error: 0 Job: 235 Name: LogCollect State: COMPLETED Error: 0
17.4. Retrieving Job Logs¶
Robin provides a utility which collects all the appropriate logs from the necessary nodes for a particular job and its consequent hierarchy. It stores these logs within a single tarball that can be provided to Robin alongside a bug report. In addition this useful for an Administrator to debug as to why a job failed unexpectedly. This functionality is extremely convienent as it automates the process of the user logging into every affected node and collecting/inspecting the relevant log files. Issue the following command to retrieve logs for a specific job:
# robin job get <id>
|
ID of job to collect the logs for |
Example:
# robin job get 1
Retrieving log files...
Log files for Job ids: [1] are retrieved successfully at 1582189081.tar.gz
17.5. Tool for checking data integrity on PVCs¶
Robin.io provides the devck_job_runner.sh tool for checking the data integrity of PVC on your cluster.
This tool performs a block-level checksum of data on the disks for specified volumes.
It performs checks on all volume replicas of the cluster. The tool provides the output in the form of a log file.
The log file provides details about both volumes that are healthy (checksum match) and volumes having checksum mismatch issues.
You can run the tool as per your requirements.
Note
The tool is not provided as part of Robin CNS binaries. The Robin customer support provides the tool. Contact the Robin Customer Support team when you need the tool.
The tool uses the disk bandwidth when running it and this impacts the performance of the workload. If you observe any checksum issues on your PVC, you must contact the Robin Customer Support team.
17.5.1. Running the devck_job_runner.sh tool¶
You need to log in to your Robin cluster to run this tool and run it on one PVC at a time. However, you can run multiple instances of the tool on different PVCs.
Prerequisite
You need your
image_pull_secretand the path of the repository from where you pull the images to run the script. Run thekubctl get secret -n robiniocommand to know the secret.
To run this tool, complete the following steps:
Run the following command to execute the script from your cluster.
# sh devck_job_runner.sh -n <pvc_namespace> -p <pvc_name> -s <image_pull_secret> -i <devck_image>
Note
The devck_image command option is the path of the repository from where you pull the image. Format: registry/repository/img_name:tag.
Example
[root@hypervvm-72-51 ~]# sh devck_job_runner.sh -n test-namespace -p r-2 -s test-cred
job.batch/job-devck-r-2-test-namespace created
Waiting for job to complete.
Check jobs status using this command 'kubectl logs job/job-devck-r-2-test-namespace -n robinio'
