[SOLVED] Problem Suspending with Encrypted LVM - hard disk/BIOS psswd

PiklesOnFire · 2010-01-25 22:11:01

Hello all, I was wondering if anyone has been able to get an encrypted lvm to resume from suspend?
Every time I try, it looks like it came back, but then I have no access to the hard drive.
ls says input/output error.
xfce4-panel keeps popping up "resource missing" messages with little boxes instead of text for the title.

Any help with this would be amazing

Yeah, of course this is working without a hitch for lots of people. Sorry I have no insight into why you're having problems. Questions that may help people help you: Are you in a position to swear that the same installation (kernel, drivers, settings, version of pm-utils, etc) works fine on your hardware when the (same) drives aren't encrypted lvm? Are you using dm-crypt/LUKS or another sort of encryption? On top of lvm, or lvm on top of your encryption? Which parts of your filesystem are on the encrypted lvm partitions? Presumably not /boot, are any other parts not? Can you resume from hibernation? Are you really _entirely_ sure your hardware setup resumes from suspend with your system even when encrypted lvm is not part of the equation?

PiklesOnFire · 2010-01-26 02:22:10

Yep, everything works fine when not encrypted. I even installed a second IDENTICAL copy, minus encryption, and used every method i could find, they ALL worked, none are working w/ the crypted lvm.
Yes, it is a dm-crypt/LUKS, and it's the entire LVM is on an encrypted block (I always get mixed up when saying this on top of that, so hopefully this is clear).
Every bit of my system is crypted LVM except /boot. It resides on a usb thumb drive.
I haven't even tried Hibernation (doh!) because I'm really more concerned about suspend atm.
And yes, i'm 100% entirely sure it comes from suspend when not encrypted. Give me a couple hours, I'm going to take my dar image and put it back on usb, and test it again, because I want to 100% sure ;p

Profjim · 2010-01-26 02:45:59

Hmm, that's my setup too (dm-crypt installed first, LVM on top of it), except mine's even more complex. What kind of hardware are you using: internal laptop hard drive? not a solid-state drive. What filesystem are you using on the drive (though I expect this isn't part of the problem). What method are you using to suspend: just bare /usr/sbin/pm-suspend from pm-utils? Anything other than pm-utils running which might be controlling your laptop drive, like laptop-mode-tools?

PiklesOnFire · 2010-01-26 02:52:35

Yep! internal drive, not ssd. it's all xfs except swap, obviously, and boot, which is ext3.
i've tried every suspend option i could find, including tuxonice, which simply REFUSES to suspend.

btw - the hardware is a dell E1705, radeon X1400, i can post lspci if needed, though.

PiklesOnFire · 2010-01-26 04:04:17

BTW - Using pm-utils I can recover from a hibernation. It's just suspending that doesn't work for some reason. fml

Profjim · 2010-01-26 09:19:32

pm-utils writes to a log file, on my machine it's /var/log/pm-suspend.log, though I don't remember if that's the default or if I renamed it. Does that tell us anything useful? Any useful error messages in the block where it's trying to resume?

PiklesOnFire · 2010-01-26 20:07:08

I can't SEE any errors when it's trying to resume... My system just locks up.
I'm not 100% sure, but I think it's not remounting my drive (at least, that's how it appears)

here is a copy of my /var/log/pm-suspend.log

Mon Jan 25 23:04:53 EST 2010: performing suspend

It doesn't even show it trying to resume =/

Profjim · 2010-01-27 00:55:10

Looks like you've got laptop-mode installed. I don't. I think most everything it does can be done more directly, it's just an extra layer of complication. Anyway, you can try removing that and seeing if that improves the suspend/resume situation at all.

Also, I don't know what encryption you're using but in my case I have to load the module aes_x86_64. That doesn't show up in your modules list. Probably if you needed it you wouldn't even be able to boot, but I thought I'd mention it in case.

PiklesOnFire · 2010-01-27 20:50:41

heh, I tried it before I even installed laptop-mode-tools ;p
but, after removing it, still no success.

I'm using twofish encryption, and it's module is in that list, so i'm still at a loss.

For the time being, until I can figure out what's wrong, I have just aliased suspend to pm-hibernate, as again, hibernation works without a hitch.

Profjim · 2010-01-27 22:07:25

Sorry we haven't made progress. Isn't it ridiculous that in 2010 suspend/resume is still so much a black art?

I JUST solved the issue.
After days of searching, I found a post where someone had mentioned they had a password set for their hard disk.
This is a feature available w/ some BIOS, and that, as well as the fact that I had an "admin" password set in the BIOS was causing the issue.

In short, the disk gets unlocked at boot, but when resuming from suspend it doesn't prompt for it again, therefore leaving the disk locked.
What I was seeing was simply an image pulled from RAM, explaining why all other hardware was functional except the Hard Disk.

SUSPEND AND HIBERNATE NOW BOTH FULLY WORK!!!!!!!

Hope this helps someone else out as well!!

EDIT: I have actually wrote a blog, to hopefully prevent others from having this issue as well: http://my.opera.com/PiklesOnFire/blog/t … om-suspend

Good that you solved it, and this is good to know as well. I don't use my BIOS password, but I was planning to do so someday. It sounds like it should be broken on resume regardless of whether one's using disk encruption, then, no?

No, because the drive is still decrypted in the ram's mind.
But it's not "unlocked" as per the motherboard's mind.

it's sorta complicated, but it makes sense. lol.
