Include partclone 3.20?

@sebastian-roth said in Include partclone 3.20?:
I was able to manually link one of the binaries by adding -ldl
This is the path I was going down too when researching the error they just said put -ldl as the last library in the linker. The question was where (ignorance of buildroot)? The other thing I thought is update the version of buildroot to current, maybe a later release of build root would have a compatible version of the crypto lib.
The other thing I found is that ubuntu has 0.3.20 with some kind of patch level beyond 0.3.20 but I couldn’t find the source files to see if building that had fixed the crypto lib errors.

@sebastian-roth Ok thanks, I will try it out and report back. These inits, they just go on the FOG server right? Or do I also need to add something to the mac OS Grub/FOS boot stick?

Which way did you create that boot stick?
Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)
Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

@sebastian-roth Uhm… @george1421 can probably answer that better than I can.
Sorry for deleting and reposting the replies. The way the thread looks after replying, it looks like I replied to the OP and not to another reply.

The OP used the tutorial I created to boot into grub and then into fos linux on a usb stick. But it sill uses the standard bzImage and init.xz. So no difference there. We still need buildroot to compile correctly.

Thanks, I wasn’t sure how this one was made. I downloaded the img and used rufus to write it onto a USB. It works great by the way.

@Fog_Newb There you go: https://github.com/FOGProject/fos/releases/tag/testing
Just download
init.xzand put in/var/www/html/fog/service/ipxe/in your FOG server - rename the original file instead of overwriting it! -
@fog_newb FWIW: the testing
init.xzgoes onto the flash drive if you are booting with that./var/www/html/fog/service/ipxe/is used when pxe booting via iPXE into the FOG menu. -
@sebastian-roth @george1421 Good news!
So far so good. I was able to capture the APFS drive on the real mac using the USB stick and the updated init.xy. I put the updated init.xy on both the stick and the server.
I was also able to capture both drives APFS and NTFS on the hackintosh laptop. Now I have to figure out how to back up the data in case deploying the images goes sideways.

@fog_newb Thanks for testing and the quick feedback.

Which data do you mean? On the device? Probably using Clonezilla to have a backup at hand?!?
-
@sebastian-roth Yes, Clonezilla but I need to get some more SSDs/HDDs.

@sebastian-roth Does 1.5.9.163 have these new inits?
I read the dev-branch info but wasn’t sure. I never know what most of that stuff means.

No these inits are still in testing phase. Since partclone is at the heart of FOG imaging and the versions jumped from 0.3.13 to 0.3.20 these inits must have more testing with people before they are added to the dev branch and then onto the 1.5.10 when its released. They might work great with your hardware but fail on some genericly assembled computer.

I’m currently testing init.xz images built by myself using the partclone-0320 branch. In addition, these images have, for my part, added these two commits of mine from github that fix bugs with BTRFS (https://github.com/FOGProject/fos/pull/47 https://github.com/FOGProject/fos/pull/45). The whole thing was built using Buildroot 2022.02.5, which fixes bugs related to udev (https://github.com/FOGProject/fos/issues/46). I know it’s too many changes to treat my experience as relevant to the addition of this particular partclone version, but I think it’s worth sharing anyway.
The FOG server on which this custom init.xz runs is based on Fedora 36 (/images on XFS), the latest (at the time of writing this) development version of FOG, compiled kernel 5.15.71, and an updated version of UDPcast to 20200328 (the latest does not work with FOG). This server, runs in production, so there are 30 images restored each day, and sometimes more (mostly Windows 10 and Ubuntu). But it happens to image other computers that have other systems, such as Fedora 36 Workstation with the BTRFS file system. I mainly use Multicast restore (computers in the school computer lab), but sometimes I need to restore one computer and I use Unicast.
The previous FOG server was based on Debian 10 (/images on EXT4), FOG 1.5.9 and the latest official kernel and init.xz. The situation has changed dramatically after the migration.
On the old system, using Unicast I was getting speeds of around 7-8GB/min (for both restore and capture). With Multicast, this speed increased to 12GB/min.
After I built the server on Fedora, I used init.xz from the partclone-0320 branch without patches and the official 5.15.68 kernel and the speed increased to 14GB/min using both Multicast and Unicast. The capture speed went up to 9GB/min. After changing init.xz to the current one, the speeds have not changed, but at least I can safely restore the BTRFS file system without any errors.
I don’t know how much of this is due to Partclone 3.20 and how much is due to migrating the system to Fedora with XFS, but I can say that so far Partclone 3.20 is running very stably and hasn’t crashed yet. And I have already restored images based on NTFS, XFS, EXT4 and BTRFS. If I only notice any flaws with the operation of the whole thing I will describe them. But so far I have no complaints about my system. If it continues to perform as well as it does now I will migrate the FOGs in other computer labs to what I am using in this particular one.

@piotr86pl Excellent feedback. While you have many accomplishments, it would be interesting in your buildroot configs to roll partclone back to 0.3.13 (only) and see if your side by side comparison still holds. This will kind of give the developers insight to if the partclone upgrade generated these improvements or it was updating buildroot to something current and optimized for linux 5.15.x,
Either well done rebuilding the FOG imaging environment and the performance gains you have.

I built init.xz with partclone 0.3.13, with no changes to buildroot or scripts, and ran a series of tests. The end result was a difference of 1GB/min in some cases in favour of partclone 0.3.20, but this is a marginal difference to take into account. I noticed that partclone 0.3.13 was a little slower to start than partclone 0.3.20, i.e. after the message “Attempting to deploy image”, it took longer to start partclone 0.3.13 than 0.3.20 - about half a minute.
In general, changing the partclone version here is unlikely to affect the speed of image restoration, but more on things like support for non-Linux filesystems like NTFS or support for more exotic filesystems like BTRFS.
Also, I wouldn’t rush to update partclone to version 0.3.20, but I would definitely see it already when FOG 1.5.10 is released, as it fixes a few bugs after all and doesn’t cause me any problems. I would also give buildroot in a newer version for the release of FOG 1.5.10, so as not to scare users away with those udev warnings that appear because of eudev. But it’s all up to the developers now. I’ll keep an eye on the operation of my setup and as soon as something happens I’ll investigate it and let you know.

First of all, thank you for taking time to debug/test the setup with the old version of partclone and the current version. Its important to know exactly which change made a difference in the imaging times.
If we can get enough people to test the development ints (the ones issued by the developers not in the current dev branch) and prove them out, I’m sure that 0.3.20 will be in the 1.5.10 release. As noted in this thread partclone 0.3.20 addresses an issue with the apple file system so there is more pressure to get it into the 1.5.10 over a speed improvement.
@Developers please note the testing by @Piotr86PL

It seems to me that when it comes to increasing the performance of FOG, server configuration makes a big difference.
The previous server was based on Debian 10 with FOG 1.5.9, and the /images directory was on the EXT4 partition. The server was virtualised with VMware ESXi and files were kept on an array of HP 7200RPM SAS drives. The configuration was the default - as it was after the FOG installation. That’s when I was achieving 7-8GB/min on PCs (with NVMe drives) for capture and deployment and 12GB/min for multicast. We are talking about a Windows 10 image (NTFS). With an image with Ubuntu 20.04 (EXT4), the speeds were definitely higher - 18GB/min with Multicast and 12GB/min with Unicast.
However, I wondered if it would be possible to squeeze more out of the whole thing, so I set up a virtual machine based on Fedora 36 with the XFS file system (which supposedly handles large files well, which disk images certainly are). I installed the latest development version of FOG. After installation, I manually compiled Udpcast version 28.03.2020 (the latest one doesn’t work with FOG - it crashes as soon as a multicast session starts). I added the following options to the sysctl.conf file:
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.core.rmem_default = 312144
net.core.rmem_max = 312144
net.core.wmem_default = 312144
net.core.wmem_max = 312144
to disable IPv6 (which I do not use) and to increase the socket buffer size. Additionally, I set 128 threads in the NFS settings, as the default is a small number (and the server is running on a vSphere cluster). Still in the FOG itself in the Storage Node settings I set the bitrate to 1000M. I’ve also compiled the latest kernel to make sure the latest patches are working (I’ve disabled SPECULATION_MITIGATIONS as I’ve read that this can affect CPU performance, and sometimes I find myself imaging computers with really weak CPUs). I also prepared my own init.xz with partclone 0.3.20, and then added these patches to the scripts and updated Buildroot to not have problems with BTRFS.Also, this is how my current FOG configuration looks - as if anyone was curious what exactly I changed that made me achieve the speeds I did. A bit of an offtopic, but maybe it will be of use to someone.
