I am unable to re-index or access issues and dashboards, help?

[Alex Pomerantz]

We use JIRA version 6.4.3.

Over the past few weeks our JIRA instance's performance has become more volatile. Re-indexing fails whenever I attempt it. Dashboards display long strings of error messages and users are unable to access any issues.

The Health Check function detected a problem with our indexing, but the other categories appear healthy.

The error I recieve when trying to access issues or queries is "Error getting the next result (I/O Error: There is not enough space on the disk)".

I am attempting to run a query to see if I can delete attachments to clear up space, but that is failing as well.

Any assistance would be greatly appreciated.

It appears your disk is full. Try cleaing old log files first.

What operating system are you running?

If linux you can try ncdu or find: 

cd / && ncdu

find / -size +100M -printf "%s - %p\n"
