Jira and large file attachments

Matt Wilson_grxhwo

I'm in the process of absorbing multiple small Jira instance into one big jira instance. One of our smaller site has been allowing very large file attachments (currently 100MB, but they'd like to go even bigger). Our other sites are all running the default 10MB max attachment option.

My personal preference is to see large files stored on a system that is designed/optimized for file transfer (i.e. a file share, or something like Artifactory/nexus).

Is there a good way to pull this off in Jira, i.e. linking my Jira application to a file sharing service. I know I could do something with web links, but I'd like to see something a little nicer. Something along the lines of how you can see Bitbucket activities related to the ticket. Any plugins out there I should be looking at?

Hi Matt,

This can be done by remapping the attachments folder inside the $jira-home/data directory.

Details can be seen in the KB "How to change the attachments directory on JIRA".

However this does come with a warning where if the remote file storage system goes down or experiences a connection issue the attachments can become disconnected and flagged as missing in the Jira database if the files are attempted to be accessed on the front end while the error is occuring requiring some additional recovery steps if you ever encounter a disconnection issue details on recovering images in a scenario like this is covered in "Resolve Missing Attachments in JIRA"

Earl

Hi Earl,

I think you misunderstood my question. I'm not looking to change anything about my attachment setup. I've currently got my attachments on a separate NFS drive with lots of space and good IO. I'm wondering if there is a way to integrate or link Jira to another service that would host these large files.

My concern with the large files is that users will be downloading these files on a fairly regular basis to examine the files locally and will that place undo strain on my Jira service.

Has Atlassian done any testing on large file attachments? Is there a sweet spot size wise? I know it can handle very large files, but is it recommended?

cheers

Matt

Hi Matt, did you find an alternative? I'm just checking because I'm having to solve a similar issue for my JIRA instance.

Especially around integration with a non-JIRA. nFS/FTP storage.

Hi Rohit,

Sorry no. No alternate solution was discovered. That said, I believe some processes where changed to minimize the size of the uploaded files...

good luck on your hunt.

I found a suggestion on this page to create a symbolic link from default path to the path where files can be stored (on a mounted NFS location) the page above. What it doesn't give information on is: whether or not the JIRA supports this configuration.

@Earl McCutcheon would you be in a position to confirm if creating such a configuration is supported by JIRA?

Earl McCutcheon

Hi @rohit agarwal ,

The mention of the symbolic link in the article you referenced falls under a customization noting the section title "Choosing a custom Attachment Path" and within Jira customizations are not covered under Atlassian Support Offerings. So, this material is provided as an optional configuration for your information only and that you use the configuration at your own risk.

The only supported configuration is the files stored locally in the default attachment path, but the risks are relatively low in most cases when setting up the files in a configuration like this as the risk scenarios would be like the example given in my initial reply where the attachment referance in the database could become disconnected from the files referance location if any communication disruption occurs to the linked location where the file is stored.

So, if there are constant network issues the risk goes up, but on stable networks the risk is low, however there is always a chance that the files can become detached and require manual maintenance to rebuild the references. Having a manual maintenance requirement contingent on external factors is why this is not a supported configuration.

Regards,
Earl

Thanks Earl for your response.

I was assuming there would be an external plugin in place for this, seemed like a common use-case to me but I haven't found anything. We have attachments that can go upto multiple Gigabytes so we want an integrated fileshare option which is seamless.
