Strictly speaking, this is not a kernel crash, it is just a failure to
write to the device and reporting an IO error and file system going
read-only as a result.
What does dmesg | grep ST8000 show?
If this 8TB is an SMR drive ('Archive'), be aware that under certain
circumstances, like for example unplugging/unpowering too fast after
massive random writes, this kind of IO failures are to be expected.
