  • 1.  How Increase /opt

    Posted Mon November 22, 2021 09:32 AM

    Hello ;

     

    On my 3105 Qradar version 7.43 appliance the file system /opt sometimes reaches 96%.

    Is there any way to clean this file system or increase its size.

     

    Thanks for your help.

    Hi,
    there is no easy way to increase opt partition other than reinstall.
    deleting files isn't easy either as this is System partition. You should look for large files that maybe leftovers from software updates and can safely be removed. Make backups first. For getting more specific instructions use df -h command and paste output here. Pls double check retention policy inside GUI for purging variable data once default disk limit is reached. Lowering the specified value by 5 percent may already help

    Hi Hichem,

    as outlined before this isnt easy to fix. From the df -h output all I can see is /opt having reached 90% already. Moreover I can see that you are using forensics function inside. Maybe its a good idea to put that on an extra box?
    Running forensics on your main machine is not best practice. Not sure however as we do not use forensics in our own environment. Dont touch the lib directories.
    Instead please focus on backup and upgrade directories as mentioned before. /opt/qradar/upgrade/728-backup/ would be an example. Use du -h to determine which subdirs contain how much xxM or xG. cd into /opt/qradar and run du -h | grep backup. You will find many /upgrade/*backup/ and /patches/*backup subdirs including release info as listed bove, which you should be able to remove or better move into /store or /storetmp in the 1st place and softlink them if needed (safe option). When moving file use mv -p in order to keep file attributes. The backup dirs listed above should be removable. Please keep those dirs and files related to your current release if any . Be careful and dont forget the current backup!
    Good luck
    Karl
