hmm, i am now on cvs as of yesterday evening, including all your changes
in sys/geom/ up to just now (just looked in cvsweb, nothing newer than
what i use there).

but i still get corruption of data, judging by checksum testing.
again, the corrupted file i see is much more compressible than the
uncorrupted original.

(potentially this could also be an nfs-issue, as i am copying onto the
gbde partition via nfs from a 4.6-rc machine. but i can't really imagine
that, never had anything like that in all of my non-gbde freebsd nfs
experience. if it is an nfs issue, then it would probably be fbsd-5
specific - is there any such known issue ?!)

the partition in question now looks like this:
e: 117231392       16    4.2BSD     4096 16384    64  # (Cyl.    0*- 7297*)

this time i inited gbde's sectorsize to "4096". last time i reported
corruption, gbde's sectorsize was at its default (i presume 512). the
corruption then 'felt' just the same. very sporadic - and somewhat
non-deterministic from my point of view.

Heiko
