I have the following geom options in my kernel config:
GEOM_LABEL
GEOM_PART_BSD
GEOM_PART_GPT
GEOM_PART_MBR
The last three are recent addition that I want to report about.
Also, geom_mirror and geom_journal are loaded as modules and I use both
gmirror and gjournal, independently.
This is a i386 7.1-PRERELEASE system, kernel is built from svn rev. 184137.
Here's a diff between new kernel verbose dmesg and old kernel verbose
dmesg (only geom specific lines, old kernel was built from sources from
around Sep 24):
-GEOM: new disk ad4
+GEOM: ad4s1: invalid disklabel.
+WARNING: Expected rawoffset 0, found 63
+GEOM: ad4s1: invalid disklabel.
+WARNING: Expected rawoffset 0, found 587191815
+GEOM: ad4s1b: invalid disklabel.
+GEOM: ad4s1c: invalid disklabel.
GEOM_JOURNAL: Journal 1799301102: ad4s1d contains data.
GEOM_JOURNAL: Journal 1508823937: ad4s1e contains data.
GEOM_LABEL: Label for provider ad4s1e is ufs/export.
GEOM_MIRROR: Device mirror/rootfs launched (2/2).
GEOM_JOURNAL: Journal 1799301102: ad4s2d contains journal.
GEOM_JOURNAL: Journal ad4s1d clean.
GEOM_JOURNAL: Journal 1508823937: ad4s2e contains journal.
GEOM_JOURNAL: Journal ad4s1e clean.
GEOM_LABEL: Label for provider ad4s2f is ufs/xtra.
+GEOM_MIRROR: Cannot add disk ad4s2ca to rootfs (error=17).
GEOM_LABEL: Label for provider ad4s1d.journal is ufs/system.
GEOM_LABEL: Label ufs/system removed.
The strange messages are ones about invalid disklabel and also about
trying to add ad4s2ca to 'rootfs' mirror.
On disk ad4 I have two slices and a number of partitions within each.
Now I got some new devices for the second slice.
Old devices:
/dev/ad4s2
/dev/ad4s2a
/dev/ad4s2c
/dev/ad4s2d
/dev/ad4s2e
/dev/ad4s2f
Plus new devices:
/dev/ad4s2ca
/dev/ad4s2cd
/dev/ad4s2ce
/dev/ad4s2cf
Here's more data/info:
$ fdisk ad4
******* Working on device /dev/ad4 *******
parameters extracted from in-core disklabel are:
cylinders=620181 heads=16 sectors/track=63 (1008 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=620181 heads=16 sectors/track=63 (1008 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:

end: cyl 1023/ head 8/ sector 63
The data for partition 2 is:
