Very slow cloning speed on specific model
-
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.
-
@DeRo93 In what Mode is the drive being read to the system? From BIOS you may find something like SATA Operation.
Can you change this to AHCI and see if this helps improve the speeds a bit? Maybe change to ATA - IDE if it’s available?
-
@Tom-Elliott HP UEFI does not have AHCI - IDE Options in their UEFI Setup
HP says AHCI is activated by default on newer Models. -
@Tom-Elliott As far as I understand, this problem is occurring specifically on NVME SSDs
-
Did anyone get this working?
I have a large batch of the EliteBook 840 G6.
Some of which build and other are extremely slow.
Looks like my batch has 2 versions or firmware versions.
The one that works is “Toshiba KXG60ZNV256G 79VA215DKRVN” and the other is the same drive but an older firmware by the looks of it.
Im in contact with HP to see about getting a firmware updater…
-
Littlwe update.
So i swapped SSD out of a “slow” building laptop into a “working full speed” laptop.
So i thought the working laptop would now build slow, well it didnt. Building at full speed.
The other laptop with the SSD from the original full speed laptop is still building slow.
So maybe its not SSD related, but something on the motherboard?
-
@Duncan Are the BIOS versions the same on these laptops? Settings too?
