Access to Jira

[Sali Heta]

Hi Community

I started a new job at a new company as an IT admin. If I try to access our Jira server i only get an error message as soon as I try to go to the website (https://jira.tem.ch/jira/secure/errors.jsp). It's hosted on our server and I've checked everything I could. What made me doubt everything was, when I looked into the event log and there I've found an error

( A corruption was discovered in the file system structure on volume D:.

A corruption was found in a file system index structure. The file reference number is 0x7f0000000005d9. The name of the file is "\Program Files\Atlassian\Application Data\JIRA\plugins\.osgi-plugins\felix\felix-cache". The corrupted index attribute is ":$I30:$INDEX_ALLOCATION". )

I also checked the services ( SQL Agents running, Jira 8.21.1 Service running, Apache 2.4.17 running, TomCat running).

I cant get the server running and I dont know what to do anymore. Any help would be appreciated!!

Thanks in advance and regards
