Intel Raid0 Image Capture

@Tom-Elliott getPartitons from download. I’ll have to look at the code again

[edit] here is the call chain
fog.download:restorePartition->funcs.sh:runPartprobe->funcs.sh:performRestore->funcs.sh:getValidRestorePartitions->funcs.sh:getPartitions

Updating the trouble code
lsblk -I 3,8,9,179,259 -lpno KNAME,TYPE /dev/md126 | awk '{if ($2 ~ /part/) print $1}'

to
lsblk -I 3,8,9,179,259 -lpno KNAME,TYPE /dev/md126 | awk '{if ($2 ~ /md/) print $1}'

Allowed the system to image in debug mode. I doubt it will run because I don’t have the raid drivers in my pushed image, but imaging did complete fully without error.

@Sebastian-Roth said in Intel Raid0 Image Capture:

@jpmartin George’s mdadm -D /dev/md126 seems to be very handy and informative. Give that a try!

No image file found that would match the partitions to be restored
args passed /dev/md126 /images/WIN7ENTX64 all

Guess that’s just a matter of tuning the init scripts to make this work. Will have a look tomorrow. Marking this unread…

Here you go:

mdadm -D /dev/md126.txt

@george1421 Have you been able to capture an image from the machine?

Do you think it’d be possible to capture a Single Disk Resizable image from these fake raid machines?

[Tom Elliott]

I updated the source for this to allow for if ($2 ~ /part/ || $2 ~ /md/).

Hopefully this will work for you needs.

[george1421]

@Tom-Elliott That should do it very nicely!!

The OP will need to update to the latest release of the FOG trunk once the change has been pushed. I can confirm that it works. I still have my test rig set running.

As for “Do you think it’d be possible to capture a Single Disk Resizable image from these fake raid machines?”. I was able to deploy to this machine once I hacked the init (not needed now) so I also assume you should be able to capture resizeable. My deploy was a single disk resizeable image.

[Tom Elliott]

@george1421 I don’t know if it will “capture” unless the primary device is set though.

[george1421]

@Tom-Elliott Right. I know I have a wall of text in this one. But to use these fake raid systems you have to update the host registration with these settings. Without these set FOS will only see just a bunch of disks and not the array.

Host Kernel Arguments: mdraid=true
Host Primary Disk: /dev/md126

[edit] Corrected the extra bits in the host primary disk

@george1421 where does “Here” come from in “/dev/md126Here” in your post just below?

[Tom Elliott]

@jpmartin I think he was just typing. Ultimately, remove the “Here” as I highly doubt you all have a “/dev/md126Here” labeled device. :smiley_face_here:

As we don’t have smilies I suppose it would be better to add a bit that I’m just playing around.

[jpmartin]

@Tom-Elliott That’s what I was thinking too. But was just checking to make sure I didn’t miss anything.

Have the changes been pushed to the svn trunk so I can update and test?

Sorry trying to do my job and play at the same time, victim of copy/paste. Tom is right its just /dev/md126

[Tom Elliott]

Yes, changes have been pushed and init’s are updated. Reinstalling will work as well, but I still say to just update.

[jpmartin]

@Tom-Elliott Excellent. I’ll update and report back.

[george1421]

Bingo!! my test bench system is deploying!!

[jpmartin]

Running a Resizable Capture now.

Fog is resizing the file system currently.

Will test deploy after this image is captured.

[jpmartin]

Resizable capture worked perfectly.

Running deploy now, should be finished in ~6 minutes, all is looking good so far.

[george1421]

@jpmartin That’s great!! I’ll have to write this up in a tutorial so that its document properly now.

Thank you guys for working together and getting this fixed in just about 24 hours! This is amazing!

[jpmartin]

@george1421 I restored the image as multicast and it errored on one machine after the image was downloaded. I forget the error it threw specifically but it complained about not being able to mount or unmount a partition.

That machine rebooted, then advanced to the same spot that the other was sitting.

It was a partclone screen saying “restoring image (-) to drive/device (/dev/sda1)” and I wasn’t able to hangout long enough to see if it advanced.

I’ll be back in the office in an hour or so, I can give an update then and provide any additional information that may be helpful if the imaging process didn’t finish. I’m hoping it figured itself out after I left for a meeting.

I’m an intern exploring Fog Project as a potential solution to some of our imaging issues, I’ll be sure to make the point that if we end up implementing Fog Project that we should make a donation to support the efforts.
