    • RE: Multiple I/O Errors during imaging

      @george1421
      Thank you for the feedback!

      I’ve taken your advice and since tested with a MB BIOS flash and a firmware update on the P2 drives (there was one available), and also a few different FOG kernels just in case. Same results with all of that.

      I currently have 2 systems that just won’t take this large image with the P2 drives, so I was able to use the same systems and do a multicast on 1TB SSD’s instead. That passed with flying colors.

      We don’t have any commercial build systems here, but we do have a different model of M.2 drive, so I’m currently testing with that.

      I wasn’t able to get the debug mode to work just yet, but I’ll give that a try again after this different model of M.2 testing. I’ll provide an update to my testing.

      Another part of the truth table though, is that all of these Crucial P2 drives were actually imaged with a ~1TB image many months ago when they were initially installed. Most locations were brand new systems with these drives, but we also have one location that has older model systems (B360M chipset) where we just upgraded the M.2 drive to these Crucials. To the best of my knowledge, the first round of imaging did not produce any of these issues, which is about 250+ systems. It wasn’t until the 2nd, and some 3rd round that these issues started to occur.

      @sebastian-roth
      I’ve only been able to test this in one environment and only with 2 PCs. It did work in that particular test. In a couple of weeks, we are going to have an opportunity to hit a good number of PC’s in another environment where it previously failed, so we’ll have more data then. So far so good though! Thank you much!

      @sebastian-roth
      We are using 1.5.9
      The kernel we use does vary between stores though. 5.10.50 is a popular one though, but we’ve used older and I’ve tried the 5.10.71 (nothing newer than that).

      That’s very strange too. Especially considering that the issue seemingly appeared with no changes made to FOG and across multiple locations.

      @dmcadams FYI, yes this is a Windows 11 image, but I can assure you that this has nothing to do with Windows 11. We first noticed this at 2 other locations using Windows 10. We just happen to be testing with 11 right now.

    • Multicast image is pushed, but it does not "finish/finalize"

      Hello, we first experienced this issue back in December during one of our store openings. Since it was a new install, we just dealt with it and thought this was some strange glitch. Since then, we’ve actually noticed the same thing at 2 other locations, both of which we made no changes, and didn’t previously see this issue. We really don’t multicast often, so that’s why its been several months.

      Issue:
      Multicast image is deployed and gets to 100% on all partitions. No matter how many systems we have going, only 1 PC will actually “finish” the image and reboot. The other PCs will all sit on the partclone screen, and we have to stop the FOG task, then manually reboot the PCs. These PCs that need to be manually rebooted do not get their PC name changed (it remains the same name as the source image PC). So whatever stage/phase where the PC name gets changed, is only running on 1 PC. All others will remain stuck until manual intervention.

      As mentioned, we didn’t see this issue prior to our December opening. We opened a location in November and successfully multicasted over 120+ PCs in a few chunks. That same location, with no changes made to FOG, now experiences this issue.
      We have since tried a few different kernel versions with no luck.

      Has anyone experienced this? Ultimately, we do have a work around, so this isn’t a huge deal. It just gets frustrating as most of what we do is remote, so this issue does cause a delay in the process to wait for onsite assistance.

    • RE: Multicast session is not starting

      @sebastian-roth
      Thanks for the great information. We will give that a try. Also, the FOG_MULTICAST_RENDEZVOUS was actually one of our last attempts. I will revert that back to the default of blank first, and remove that portion from the commands that you sent.

      These client machines also have NVMe drives, so on the receiver side, instead of “/dev/sda1” should we use “/dev/nvme0”?

      Yes they are all on the 192.168.48.0/24 network.

      @sebastian-roth
      Yes, same hardware and same configuration. At least as 2 other sites.
      A couple of other sites have some differences.

      Is there a better log that I can look at to see why its just hanging there? I was hoping for one of those debug modes but for Multicast, or that the Multicast log would show something.

      At this site, we have not had Multicast working. We do have 6 other sites using the same type of setup and networking gear. Those sites we have Multicast working, and we don’t recall needing to do anything special to get it working, other than tweaking some performance settings like IGMP.
      Yes, they are on the same IP subnet as the Fog server.

      Here is a snip of the Multicast.log that I just attempted:

    • Multicast session is not starting

      Hi,
      We are experiencing an issue at a new location where the Multicast session is not starting. See the attached picture. It will go all the way to the partclone screen, and just hang there. We have verified that Unicast image works just fine, using the same image, on the same machines. We can even do multiple systems with that image via Unicast. We’ve been trying with 2 systems, and also tried with 2 different systems.
      We setup FOG with default settings, using Ubuntu 20.04 LTS and then we tried again with 18.04 LTS. Changing only IP and passwords really. Any help would be appreciated!

    • RE: Multiple I/O Errors during imaging

      Another part of the truth table though, is that all of these Crucial P2 drives were actually imaged with a ~1TB image many months ago when they were initially installed.

      Maybe this way using an older kernel. You can try manually downloading older kernels from our website. Put into /var/www/html/fog/service/ipxe/ and set Host Kernel to the older kernel filename on a specific host (host’s settings in the FOG web UI) for testing.

      @Sebastian-Roth So I’m trying the easy things first. I have a system that just would not image to the P2 drive at all. Always throwing errors within a short time. This system works great with a 2.5" SSD, and also a different model of M.2 NVMe drive (ADATA 1TB). I installed an M.2 heatsink on the P2 and got the same errors. So…
      I went down the old kernel path like you suggested and found a kernel that not only worked on a drive that previously failed over and over, but it also didn’t produce any errors, and maintained great speeds (under 2hrs for a 800gb image). I had to try a few kernels before finding one that would even boot without a kernel panic, but finally landed on 4.19.6 (64bit). Is there anything that makes sense about why this kernel would work? Maybe it isn’t reading the temperatures correctly (or it is?) so its not throwing the I/O errors? What are your thoughts?
