Hi,
I just installed a FreeBSD 10.0-STABLE system where I:
- Created a GPT partition on da0, with a label of, say 'abcdef'
- Did a 'geli init / geli attach' on that GPT label, i.e.
geli init -s 4096 -K abcdef.key -l 256 -P /dev/gpt/abcdef
- Attached to that:
geli attach -k abcdef.key -p /dev/gpt/abcdef
This correctly gives me '/dev/gpt/abcdef.eli' The *first* time I did this I
then did:
gpart create -s gpt /dev/gpt/abcdef.eli
Which worked - and then went on to create a partition and use it for ZFS.
After a while I decided to re-do the disks (switching out '-l 256' to use
the default key size).
But now I'm stuck - I can:
- Create a GPT partition with label on the underlying device, e.g. as
before, create a GPT partition on da0 with a label of 'abcdef'
- 'geli init' and 'geli attach' to that label - and I get a corresponding
.eli device - e.g. '/dev/gpt/abcdef.eli' - but I can't do anything with
that device now:
gpart create -s gpt /dev/gpt/abcdef.eli
gpart: provider: Device not configured
I can't read, or write to it either:
dd if=/dev/gpt/abcdef.eli | strings
dd: /dev/gpt/abcdef.eli: Invalid argument
0+0 records in
0+0 records out
0 bytes transferred in 0.000059 secs (0 bytes/sec)
No errors are output anywhere - and the geli 'attach' to the first label
succeeds (and I get a corresponding .eli device) - but it doesn't "work".
Any ideas?
I know this worked once (when the disks were 'new') - as I still have it in
my scroll back. I've tried all incantations of 'gpart destroy' and 'geli
clean' - but no matter what I do (including rebooting), I can't get this to
work again.
If I use geli on the raw da0 device - I end up with 'da0.eli' - and I *can*
access / GPT partition that, but it no longer works applying GELI to a
label (but, like I said - I was able to do this once!)
