Description Holger Wansing 2006-03-14 20:14:27 UTC

Please describe the problem:
First to say, I found this when trying the gparted livecd 0.2.2-3:

On my machine I use hibernation with the software-suspend2 inplementation
(http://suspend2.net) and data is stored on a swap partition I created
specially for this purpose.
When I have done a suspend and then start the gparted livecd, the 
"hibernation swap partition" is detected as of type "unknown".
When I start gparted livecd after a normal system shutdown, the swap partition
is detected correctly as "linux swap".
But: I'm not sure if this is an error or if this is intended; I only
wanted you to know.

Steps to reproduce:
1. start my normal debian installation
2. suspend the system with software-suspend2 implementation
3. start laptop with gparted livecd
4. look for detected swap partitions


Actual results:
Swap partition is not detected as such, is detected as of type unknown

Expected results:
Not sure (see above)

Does this happen every time?
Yes.

Comment 1 Plors (Bart H) 2006-03-16 18:20:32 UTC

thanks for reporting!
Could you provide the output of:
'fdisk -lu' and 'parted <device> (press 'p' once inside parted)' for both situations?

thanks!

Comment 3 Plors (Bart H) 2006-03-16 20:44:13 UTC

thanks!
This seems to be a libparted problem, i'll look into asap or forward it to the libparted devs.

please standby as i might need more information.

Comment 4 Leslie P. Polzer 2006-03-27 23:07:52 UTC

Please provide the output of

hexdump -C /dev/hdX | head -n 50

where hdX is your suspend2 partition.

Comment 6 Leslie P. Polzer 2006-03-29 00:02:29 UTC

Scheduled for 1.7.1.

Comment 7 Holger Wansing 2006-06-25 15:42:11 UTC

This bug is fixed in vers 0.2.3-1 of the live-cd.

Thanks

Comment 8 Plors (Bart H) 2006-09-27 09:47:04 UTC

sorry, overlooked this one. I just heard this issue isn't fixed yet (from a guy who heard it from Leslie). Are you sure it's fixed Holger?

Comment 9 Plors (Bart H) 2006-09-27 10:16:50 UTC

http://bugzilla.gnome.org/show_bug.cgi?id=342369
that one seems to have the 'reversed problem' :) 'The hibernation partition gets misreported as Linux Swap'.

I guess there is a relation and all this comes down to fixing/improving ped_file_system_probe()

Debarshi told me he is working on this (or at least investigating it), so there is hope :)

Comment 10 Debarshi Ray 2006-09-27 10:45:33 UTC

I am a bit confused. Could anyone clear these:
a. Is this one fixed?
b. What should the partion being tagged 'unknown' be?

Comment 11 Plors (Bart H) 2006-09-27 10:47:53 UTC

Hi debarshi, well, according to Holger it's fixed (comment #7) or at least it works for him, but according to you it isn't (Heard from Leslie). That why i asked Holger to confirm this.

Hmm, I'm a little bit confused.
In fact the bug is not fixed.
Don't know what happened that day to let me think it is ...
(I tried today with version 0.2.3 + 0.2.5 + 0.3.1 of the livecd:
bug not fixed in all that versions)

Sorry for the trouble

Holger

Are you sure about the hexdump output with the hibernation signature on? Each time I did `hexdump -C /dev/hdaX | grep -n 50` on the hibernation partition, I got 'S1SUSPEND[0x00]' as the hibernation signature. The signature starts 10 bytes before the end of the first page on the swap area. The exact location from which the clean swap partition's signature, 'SWAPSPACE2', also starts. 00000ff6 is the location in this case.

I used the 'hibernate' option on Ubuntu 6.06 Dapper Drake, and Fedora Core 6 Zod systems running the GNOME desktop. Which distribution were you on?

Yes, I am sure about the signature!
Please read the initial report. I was referring to that what is known as
"suspend2", which is *not* the in-kernel suspend functionality from the vanilla kernel, but an alternative software-suspend implementation (see http://suspend2.net).
Thus it's not that important, which distribution you use, I use Debian Sarge.
But you can get suspend2 running with each distribution I think.

There has been a discussion about the structure of the signature on the
suspend2-devel list (initialized by this bug report): see 

http://lists.suspend2.net/lurker/message/20060328.191659.edd7358e.en.html

Greetings
Holger

Oh, I am so sorry! The problem is there even if you use the 'swsusp' facility provided in the Linux kernel (echo shutdown > /sys/power/disk; echo disk > /sys/power/state), and hence I got a bit carried away and missed that you had mentioned Suspend2.

Any way the 'swsusp' problem has been resolved to the extent that 'print' works fine. Other commands might not work as expected. However it will improve soon. Suspend2 support will also be there soon.

Comment 16 Debarshi Ray 2007-01-17 09:53:30 UTC

Support for swsusp partitions is now available in the 'master' branch of the GNU Parted Git repository. The following commands can be used to checkout the Git repository.

git clone git+ssh://git.debian.org/git/parted/parted.git parted
git clone http://git.debian.org/git/parted/parted.git parted

Support for suspend2 paritions is next in line.

Comment 17 Curtis Gedak 2008-11-28 21:49:30 UTC

Hello Holger,

Is this problem still present with the latest version of Parted (either 1.8.8 or unofficial 1.8.9)?

(In reply to comment #17)

Yes, this problem still exists in libparted 1.8.8 (tested with gparted 
live cd 0.3.9)

Holger

Comment 19 Curtis Gedak 2008-11-30 21:12:34 UTC

Thank you Holger for confirming the problem.

Hi Debarshi,

Do you know if a bug was logged with the Parted team for this problem?

Also do you know if anyone is actively working on it?

Comment 20 Curtis Gedak 2009-08-13 22:52:37 UTC

Hi Holger,

Would you be able to test this with the latest parted release (1.9.0)?

If it is more convenient to use a Live CD, parted-1.9.0 is packaged with gparted-0.4.6 on the System Rescue CD:

To download SystemRescueCd-x86-1.2.3, visit:
http://www.sysresccd.org/Download

If the problem still persists, would you be able to re-raise the problem on the bug-parted mailing list (bug-parted@gnu.org)?

Comment 21 Holger Wansing 2009-08-20 19:58:50 UTC

(In reply to comment #20)
Hello,

I tested this with parted 1.9.0.
The short answer: Problem still (or again?) exists.

The long description: 
The swap partition with suspend2 hibernation signature on it is detected by parted as type "unknown".
"fdisk -lu" detects the partition as "Swap linux / Solaris".

Here comes the output of "hexdump -C /dev/sda5 | head -n 50" while /dev/sda5 is
clean swap space:

Comparing this output to that one I posted in Comment 5 of this bug, it seems that the suspend2 developers changed their hibernate signature in the meantime.
That's very likely the reason, why the partition is still detected as unknown.
The hexdump output provided today is from a hibernate signature created with suspend2 version 3.0.1.

Thank you Holger for retesting this problem and confirming that it exists with the latest parted 1.9.0.

Would you be able post this bug to the parted mailing list (bug-parted@gnu.org) so the parted developers can take a look at it?

It might be useful to include a link back to this bug report so the parted developers can review the trail of comments.

Thanks,
Curtis Gedak

The following quote is from bug #709640 comment #3.

----- begin quote -----

Looking at bug #334569 software-suspend2 was being used for hibernation.
As far as I can tell that is defunct.  The current implementation
included in the kernel is Linux Software Suspend and uses a different on
disk signature, but both libparted and blkid recognise that signature.

$ blkid /dev/sda10
/dev/sda10: ... TYPE="swsuspend"

$ parted /dev/sda print
...
Number  Start   End     Size    Type      File system     Flags
...
10      361GB   362GB   1074MB  logical   swsusp

----- end quote -----

In addition the Software Suspend 2 web site listed above (http://suspend2.net) no longer appears to contain content related to software suspend.

As such I am closing this as INVALID as it appears that Software Suspend 2 is no longer used.
