Full HardDrive, unable to log in

Hi

I uncompressed a huge directory that filled my HD and now I am unable to log in. I have tried all possible ways to log in and nothing works. Using single-user mode I can login but the `dir` I want to remove is `read-only`. I have not been able to make that dir read-write. Any ideas?

When I log in in single-user mode, my prompt keeps printing:

CoreStorageGroup::handleOpen(<ptr>) called, client <ptr>, access 3...

When I can finally type, I have tried

/sbin/fsck -fy

and it seems the HD is fine, no errors, no faults, nothing. When I type

/sbin/mount -uw /

nothing changes. I just need to `rm` the huge `dir` that is causing the memory issue. Is there any way to make read-write a directory while in single-user mode??

I am using an iMac (late 2016), MacOS 10.13.3 High Sierra

Thanks,
