I was trying to install an old optical drive into my system, which turned out to be having problems, so I pulled it out again, but upon rebooting back into Ubuntu 18.04, I'm unable to mount my 3-drive (16TB) linear lvm volume. I keep getting the message:
mount: /home/kp/bigdrive: mount(2) system call failed: Structure needs cleaning.
sudo e2fsck /dev/bigVG/bigvol and it comes back clean (without errors) every time. Also, the volume mounts just fine using the Ubuntu 18.04 live CD. No problems whatsoever. I'm really baffled here. Is there some kind of cached file I need to clear or something?
