Deployment Architecture

Why am I getting "Error while creating deployable apps...No such file or directory" trying to to run "apply shcluster-bundle" on our search head cluster deployer?

Splunk Version 6.3.1

After executing the following command on my deployer instance, I am seeing this error.

-bash-3.2$ ./splunk/bin/splunk apply shcluster-bundle -target https://myhost@domain.com:8089

Error while creating deployable apps: Error copying src="/opt/splunk/etc/shcluster" to tmp_staging_area="/opt/splunk/var/run/splunk/deploy.8e9ed66fdbd0ac3d.tmp": No such file or directory

The temp_staging_area does exist and permissions are okay.

I had apps symlinked in shcluster/apps...

Splunk support with confirmation of dev says the symlinks would cause issues, so I have removed them and now works fine.

just had the same problem with our Deployer. Evidently, an app had multiple files exceeding 256 characters. Errors reported in splunkd.log regarding tar: Path/name too long

To view your name + path limits:

$getconf NAME_MAX /opt/splunk
255

$ getconf PATH_MAX /opt/splunk
4096

I wonder if this is the same behavior for deployment server? Would you experience issues if you symlinked the deployment_apps?

Symlinks are no issue here, but you happen to have one "pointing" to a non-existing directory (dereferenced) from shcluster/apps to apps and/or the symlink itself doesn't have the right permissions.

Try doing a "chown -R splunkd:splunkd" on the entire Splunk install tree on the deployer. I had a similar error (and the SPL is probably my complaint) about vague error messages that was a caused by a single bad file in a completely unassociated directory.

I had the same problem and this fixed it for me (no symlinks involved);

Doing "chown -R" on the ../etc/shcluster/apps folder did the trick.

Thx!

Knowing this is an old issue, I had a similar problem on Splunk 7.0.x with the users directory going missing within the shcluster path.

It was not successful. To add a little more context about the shcluster/apps directory, I have symlinked custom apps that relate to a local git repo that I have keeping the apps up to date. Splunk dev confirmed that symlinks would cause this issue.

Ok, at least we have confirmation of an issue and a bugID.

I was told SPL-106728 was created to have more logging for the deployer instance.
