Very slow cloning speed on specific model
-
@Quazz I checked, exactly same disks were in the previous HP laptop model - 840 G5. So I think the next test I’ll do it’s downgrading BIOS version to the previous version.
-
@oleg-knysh You may also be interested in trying out an experimental init.xz that uses a newer version of partclone. Though the github issue does not indicate this resolves the issue for them, perhaps it will in this case. It’s worth a shot anyway.

@Quazz Do you have some manual as I can upgrade the Partclone?
-
@oleg-knysh Download the init file from the provided link, put it in /var/www/fog/service/ipxe
Give it a name that isn’t init.xz (eg init_partclone.xz) so it doesn’t overwrite)
Then you can change the host init file in the host settings or globally under FOG Settings -> TFTP servers (eg init_partclone.xz)

We recently received the new HP 8460 G6 which has a Western Digital PC SN520 NVMe SSD hard drive. We experienced the same problems where the imaging process with partclone was SUPER slow <10MB/min. This same fog installation had no issue with the HP 840 G5 with a Samsung SSD hard drive.
I first tried the experimental init.xz that @Quazz recommended but it failed with a kernel panic.
I then upgraded fog to the latest dev-branch and re-tried the init_partclone.xz that @Quazz recommended.
That solved the issue, I’m imaging the G6 laptop at 1.31GB/min.
Thank you for solving my problem @Quazz.jpd
-
@jondeong Just an FYI: the update to dev-branch would have updated the KERNEL RAMDISK SIZE for you to what is going to be the new size requirement. that was almost certainly the cause of the kernel panic.
-
Thank you for helping,
Just now (before upgrading FOG and Partclone) I’ve reimaged one new HP 840 G6 with the same SSD Toshiba, and the same BIOS version. Everything was fine. The speed was 1.5-1.6 GB/min.
I raise my hands
I don’t know where is the difference between “fast” and “slow” laptops.But anyway I’ll upgrade my FOG server.
-
Last update:
Update FOG to 1.5.7.2 didn’t help
Update FOG kernel to 5.1.16 didn’t help
Update Partclone to 0.3.12 (see @Quazz post) did helpMaybe it’s some spontaneous fix as it was before
I’ll update if still will be issues with imaging. -
@oleg-knysh has this continued to work for you? We have a very similar issue with the HP EliteBook 840 G6 laptops but running Fog 1.5.7.2 with Partclone 0.3.12 didn’t help us. All other laptops (Lenovos or 840 G5) work 100% of the time, but out of a batch of 20, only 2 G6 laptops imaged successfully - the rest hang on the initial partclone section or the image deploy is very slow. Hardware and BIOS are the same.
-
Thank you @Quazz ! Been tearing my hair out over this. Tried so many things, new FOG server, update to 1.5.7.4, updating to 5.1.16 kernel, using nvme_core.default_ps_max_latency_us=5500 kernel argument. None of which worked. Finally after using your new init file I am imaging at 5GB/min.
-
@Middle I have the same Problem. Updated FOG and PartClone but it does not help
. Did you find another solution? -
@Quazz Is there a way to create a .xz file for PartClone 0.3.13 ?
-
@DeRo93 Technically, yes, but it is considered unstable and unfinished.
-
@Quazz Maybe its worth a try?
-
@DeRo93 Have you tried 0.3.12? The differences between those two versions are minor.
-
@Quazz Yes I tried your .xz File. Does not solve the problem for me
I´ts a HP EliteBook 840 G6
-
@DeRo93 Unfortunately there are some issues on that model with certain SSDs (though not all) that are currently resolved.
I’m unsure where to even point the finger at this point, but extensive attempts from our side have been done with no success.
Another user was using older models to deploy their images to the drive and then put those drives into the G6 model.

Does this mean there is NO other method to get my FOG Image on this Notebook model ?
-
@DeRo93 I think what it means is we need more details. I understand it’s the same type of machine (EliteBoot 840 G6) and all, but what things have you tried?
From what I can gather, you’ve attempted the Init.xz but did you try the nvme_core.default_ps_max_latency_us=5500 being set as a kernel argument?
Can you get us a video of the problem you’re seeing?
What is “slow” in your eyes? (For example is this on deploy or capture? Capture should be slower than deploy as it’s actually collecting the data and compressing it to store to the network.)
-
Hi,
i tried the Init.xz and the kernel argument. I updated FOG and BIOS from the Notebook. Even tried older BIOS Versions.
With “slow” its like the rate is going to 20 kb / min … it starts with 70 MB / min and then goes lower and lower… Its a Deploy…
SSD in this Notebook is a “sk hynix bc501 hfm256gdjtng-8310a” with the newest firmware.
