Hi,
This is from memory (brain not ram) and I can't recreate the steps for
reasons which will be obvious, so may not be entirely accurate.
I have a sata hard disk which is divided into 2 slices. Slice 1 (ad4s1)
is about half the disk and had the remains of a standard install with
swap, / , /var, /tmp, /usr. Slice 2 (ad4s2) is the remainder and has a
single partition for data, ad4s2d. It was all created with sysinstall
and doesn't have anything special like dangerously dedicated.
The operating system on this machine is on a second hard disk which is
what I booted from.
I moved all the data from ad4s1f onto ad4s2d so that I could delete
partitions from slice 1 and make a single large partition.
I then unmounted all ad4* partitions. I may even have rebooted.
sysinstall - Configure - Label allowed me to delete ad4s1a but when I
tried to delete the other ad4s1* partitions sysinstall told me I had to
set kern.geom.debugflags=16 before I could make changes on a running
system . I set kern.geom.debugflags but changes I made in sysinstall did
not take effect, the partitions persisted, both as /dev/ad4s1* and as
entries in sysinstall
At some stage sysinstall core dumped and somewhere else ad4s2d got
deleted. I managed to recreate it and didn't lose any data.
Next I booted from a pen drive and successfully deleted the partitions
from slice 1, being very careful not to delete the partition on slice 2,
however when I exited from sysinstall ad4s2d was gone. Again I managed
to recreate it and didn't lose any data.
The bit that puzzles me is that ad4s2d disappeared twice and the second
time I am sure I didn't do any explicit steps to delete it.
Did I hit a bug in sysinstall or did I do something wrong? I didn't lose
any data in the end but I could easily have done (I know - back up - I'm
going to go and buy a nice big external hard disk very soon ;)

Everything is sorted now so I am really asking this out of curiousity.
Thanks
