Those dm-0 messages are probably a logical error. For instance, a snapshot
that is full would give those errors. You need to tell us what dm-0 is
mapped to. Look in /dev/mapper for starters.

This is normal for your new disk.

Again, this is on dm-0, not sdc.

This is normal, not sure what is has to do with filesystem desciptors.
Tell us exactly what you mean by "put a LVM on it". Did you run
pvcreate? vgcreate? lvcreate? You might find the output of "pvs"
enlightening. That will tell us what PVs you have created.
And list /dev/mapper so we know what dm-0 is, and include the output of "lvs".
