[zfs-discuss] Cannot mount encrypted filesystems.

Looking for help regaining access to
encrypted ZFS file systems that
stopped accepting the encryption key.

I have a file server with a setup
as follows:

Solaris 11 Express 1010.11/snv_151a
8 x 2-TB disks, each one divided
into three equal size partitions,
three raidz3 pools built from a
"slice" across matching partitions:


  Disk 1  Disk 8  zpools
  +--+    +--+
  |p1| .. |p1| <- slice_0
  +--+    +--+
  |p2| .. |p2| <- slice_1
  +--+    +--+
  |p3| .. |p3| <- slice_2
  +--+    +--+

zpool status shows:

  ...
  NAME          STATE
  slice_0       ONLINE
    raidz3-0    ONLINE
      c7t0d0s0  ONLINE
      c7t1d0s0  ONLINE
      c7t2d0s0  ONLINE
      c7t3d0s0  ONLINE
      c7t4d0s0  ONLINE
      c7t5d0s0  ONLINE
      c7t6d0s0  ONLINE
      c7t7d0s0  ONLINE
  ...

And several file systems on each pool:
zfs list shows:

  rpool
  ...
  rpool/export
  rpool/export/home
  rpool/export/home/user1
  ...
  slice_0
  slice_0/base
  slice_0/base/fsys_0_1
  ...
  slice_0/base/fsys_0_last
  slice_1
  slice_1/base
  slice_1/base/fsys_1_1
  ...
  slice_1/base/fsys_1_last
  ...
etc.

The intermediate "base" file systems
are there only to set attributes
to be inherited by all other file
systems in the same pool.

They were created with encryption
on, forcing all others to be encrypted.

The keysource for slice_?/base
was set to
   "passphrase,prompt"
while creating the file systems.

Then I stored the keys (one key per
pool) in files in a subdirectory
of home/user1, and set keysource for
slice_0/base to
   "passphrase,file:///export/home/user1/keys/key_0"
(Similarly for the other two pools)

So far so good.
Several weeks and several terabytes
of data later, I decided to relocate
the files with the encryption keys
from a subdir of user1 to a subdir
of root. Copied the files and set
slice_0/base keysource to
   "passphrase,file:///root/keys/key_0", etc.

That broke it. After doing that, the base
file systems (that contain no data files)
can be mounted, but trying to mount any
other fs fails with the message:
"cannot load key for ''slice_?/base/fsys_?_?'': incorrect
key.

Using "zfs set" I can set the keysource
back and forth to the original directory
and the new one, or to prompt, etc.
I can change the "canmount" attribute,
etc., but not actually mount anything.

Tried changing the files attributes
to readable by all or only by owner.
Tried setting the keysource locally for
each fs with no success (other than not
being able to set it back to inherited
from base.)

Any other thing I can do? Most of the
data is either old junk or things I can
rip again or download again, but there
are some files I can not recover from
anywhere else.

Thanks,

Did you ever export the slice_0 pool and reimport it or reboot the 
server ?  Basically are you and ZFS both 100% sure you had the correct 
passphrases stored in those files ?

Exactly how did you do that ?

zfs key -c -o keysource=passphrase,file:///root/keys/key_0

or

zfs set keysource=passphrase,file:///root/keys/key_0

The first does a key change and actually reencryptes the on disk data 
encryption keys using the newly generated AES wrapping key that is 
derived from the passphrase. The second only change where to find the 
passphrase.

Can post some sample output of:

zfs get -r encryption,keysource slice_0

In particular include a few examples of the filesystems you call
''base''
and the fsys ones.

What is important here is understanding where the encryption and 
keysource properties are set and where they are inherited.

Will do. (At least temporarily, until this
problem is solved. Long term plan is
switching to FreeNAS, even if that means
running an older version of ZFS)

The system was rebooted many times
during a period of weeks,without
any problems.
(This is a home file server,
powered up on only on evenings and
weekends, when I am at home.)

The trouble began when I tried to
change the passphrase location as
described below.

First, I did the 2nd. (Change location only)
I believe I tried the first form also *after*
things were already broken, but I''m sure the
passphrases were identical: slice_08, slice_18
and slice_28 for each pools 0/1/2. - The ''8''
to bring the length to the minimal
requirement of 8 characters.
( My goal for using encryption was just to
obfuscate the contents if, for example, I
send a disk out for repair; not to hide
anything from the NSA )

Question: I believed the keys generated from a
passphrase depend only on the passphrase, and
not on  how it is provided or where it is stored.
Is this a true statement?

Actual commands output for slice_2/... pasted at the end.
The keysource was originally, (in the still working
system,) inherited from slice_2/base. It is now set
locally. At this moment some filesystems use "prompt",
others use "file", neither works.

I did try setting the keysource to "prompt,
to "file" at the original location [ actual path:
file:///export/home/trouser/passphrases/slice_2_passphrase ]
to "file" at the new location [ actual path:
file:///root/passphrases/slice_2_passphrase ]
for all file systems. It always failed.

A ''zfs key -c'' won''t work unless a ''zfs key
-l'' or ''zfs mount'' has
successfully loaded the key first.

Can you send the ''zpool history slice_2'' output so I can see
what
commands have been run.

Almost, the passphrase case also depends on a hidden property called 
"salt" that is updated only when you do ''zfs key -c''
and was set to a
random value at the time the dataset was created.

Did you ever do a send|recv of these filesystems ?  There was a bug with 
send|recv in 151a that has since been fixed that could cause the salt to 
be zero''d out in some cases.

This is the interesting part you have set the keysource explicitly on 
every leaf dataset - you didn''t need to do that it would have been 
inherited.

What this means is that even though you have the same passphrase for 
each dataset the actual data encryption key is different because the 
passphrase value plus the hidden salt property are used together to 
generated the wrapping key.

Ah, so that''s what that was.

I hit this problem some time ago, as was discussed here.
Unfortunately, I also wrote more data into the recv''d filesystem
before the next reboot, and only after that did the new fs become
eunmountable.

So, now that the bug is understood and fixed, if i still have the
original dataset (source of the send), can I use that to recover the
salt and thus the keys and new data?

Are you saying "Abandon all hope?"

[zfs-discuss] Cannot mount encrypted filesystems.

That should have failed because the keysource property is inherited from 
slice_2/base. So you have found a bug and I can reproduce it.

The reason that should have failed is the source of where the keysource 
comes from is used to determine which dataset to look at for the hidden 
salt property.  We know what that salt property should actually be in 
your case because it is set on slice_2/base.

Unfortunately ''zfs set salt'' won''t work because salt
is read-only from
userland (so it doesn''t accidentally get overridden and cause the very 
same symptoms you have!).

In theory you would assume that you could go back to having the 
keysource inherited by running:
  ''zfs inherit keysource slice_2/base/bitsavers''

However that won''t work because of a protection we have in place to 
again avoid yet another route into these same symptoms. It will fail 
with an error message something like this:

cannot inherit keysource for ''slice_2/base/bitsavers'': use
''zfs key -c
-o keysource=...''

Using a hacked up libzfs that removes the check that ''zfs
inherit'' does
so I can get out of the situation and make the datasets accessible 
again.  So this is fixable so don''t abandon hope yet.
