I was running chkfsys on a old QNX system and got the message:
‘Warning: Bitmap on disk is smaller than the mounted disk size.
Continue?’
It let me continue, but the message is always occuring. Is this
something to be worried about?

Yes, it probably is. This suggests that you went into the partition
table and change the partition size or mapping. While, this may
make the QNX partition look bigger, it won’t allow any extra data
to be written to it – the QNX file system uses one bit in the bitmap
per block it deals with, and if the bitmap doesn’t extend to the end
of the partition, that will be wasted space. (And, the bitmap can’t
be grown.)
Unless you have a good idea of the history of this machine, it might
be a good idea to back everything on it up, then do a completely clean
install. If the partition map has been played with, some other OS might
also be confused as to who owns which blocks on the disk.
