swap slice error

Beeblebrox

Can someone please tell me what this means?
Code: 
GEOM_PART: Partition 'ada0s5' not suitable for kernel dumps (wrong type?)
No suitable dump device was found.
slice is logical, inside extended partn. fstab entry for swap is:
Code: 
# Device		Mountpoint	FStype	Options	Dump Pass
/dev/label/swpsrv0	none		swap	sw	0	0
a similar message (swap fail - kernel panic) is displayed at shutdown as well.

You need to designate a swap partition, not a complete slice.

Read dumpon(8).
 
My mistake w/ semantics. ada0s5 is a partition (albeit a logical one). swpsrv0 is the label for ada0s5
Code: 
$ swapctl -l
Device:       512-blocks       Used:
/dev/label/swpsrv0    4194280    0
/dev/md0          131072         0
 
OK, thanks I got the problem. There should be ada0s2b just like there is ada0s1a under the setup shown below. But I think there are "special problems" or "impossible" protests if I try to create a slice inside a dos "logical partition", right? So should I take the 2 G slice out of the extended section? Do you have any suggestions?

That shouldn't be a problem. The only 'problem' with that setup is that you can't install FreeBSD on an MS-DOS/BIOS extended/logical 'partition'. You can use them once FreeBSD is booted though. The extended DOS/BIOS partitions will show up as slice 5 and higher.
 
Unable to correct the error

This should be simple, but I'm just not getting there. What I have now for the slice structure is:
# disklabel -A /dev/ada0s5
Code: 
# /dev/ada0s5:
type: unknown
disk: amnesiac
label: 
flags:
bytes/sector: 512
sectors/track: 63
tracks/cylinder: 16
sectors/cylinder: 1008
cylinders: 4159
sectors/unit: 4192902

8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  b:  4192886       16      swap                    
  c:  4192902        0    unused        0     0         # "raw" part, don't edit

I'm still getting the previously mentioned errors and when I try
# tunefs -L swpsrv0 /dev/ada0s5 or ada0s5b
Code: 
tunefs: /dev/ada0s5: could not read superblock to fill out disk
