[dm-devel] Regarding dm-clone on RHEL+OEL

[Uday Jonnala]

Hi Roger,

Yes, seems like it is not supported on my box

grep -i clone /boot/config-5.4.17-2011.7.4.el8uek.x86_64
# CONFIG_DM_CLONE is not set

Seems like this is not supported.

Thanks & Regards,
Uday Kiran

You probably have to inquire with the vendor support who supplied the
kernel, but checking on a UEK kernel I have of that major version I
see this (mine is el7 not el8, but I suspect the both UEK kernels are
basically identical).

grep -i clone /boot/config-5.4.17-2102.203.6.el7uek.x86_64
# CONFIG_DM_CLONE is not set

So it was not configured/compiled into my kernel and likely not yours.

And dm-clone appears to have initially been added in 5.4 from what I
can tell so I have zero clue how stable/functional it was in that
version even if it was enabled.
