    I'm getting this message when I try to run first aid on the 2tb fusion drive in my 2016 27in iMac:

    'THere is not enough free space in the Core Storage Logical Volume Group for this operation'.

    THere's 900GB+ free on the drive itself - I can't repair the drive, even if I reboot into recovery. Anything online that looks like a fix involves wiping the drive and setting it up again. I have backups but I'd obviously rather not have to go through all that.

    Any ideas?

    Is this a fusion drive? Is it an encrypted drive?

    Do you have File Vault turned on?
    If you do, turn File Vault off, then try your drive repair.

    It is a fusion drive. File vault is turned off.

    Ah, OK.

    Other than running Disk Utility/First Aid, are you actually having a problem with your iMac?
    There might be other solutions if you can describe the real problem...

    I suspect you are going to have to split the fusion drive, reformat and then create a new fusion drive.

    If there's no particular problem, then no reason to waste time "fixing" a system, when it is not broken.
