      Hi All

      I am just curious if i am the only one who is facing this.

      I have an actual XenOrchestra which is build from the sources. Recently i've noticed, that i'm not able to download the systemlogs tgz file from Hosts -> Host -> Advanced Tab -> yellow button "Download system logs".

      I have two Hosts in a pool, they both behave the same with any browser:

      1. Download starts without estimation but at high speed
      2. Some Megabytes are downloaded (~180MiB when trying on masterhost while 90MiB on slavehost)
      3. Download speed suddenly stop an stuck at 0 for some minutes
      4. Browser considered the download as failed
      5. The file "logs.tgz" is corrupted an cannot be read.

      With google search i did not found anything useful. Am i missing something or is there currently a problem with this feature?

      Kind regards and have a nice day!

            Same problem here. In my case it downloads about 30MB before it stalls.

            XCP-ng version : 8.2.1 with March updates
            XO : I tried both 9c27b53df and the older 708b9b5bc
            Browser : Firefox and Chrome in Linux

                Ping @lsouai-vates it seems to be a bug, IDK if it's on XO or XCP-ng's side

                  @Chemikant784 Hello, and thanks for your bug report.
                  I'am currently asking the XO and XCP-NG team about it, and I keep you in touch when I have more information...

                      I'd start with checking the usual logs (notably xensource.log) when the issue happens.

                      See https://docs.xcp-ng.org/troubleshooting/log-files/

                      Yes, I know, getting logs about an issue getting logs. Of course, I mean checking them via CLI on XCP-ng hosts :).

                          @stormi Any hint on what to look for?

                          I see these entries when the download starts but no subsequent errors or anything else that stands out when the download stalls

                              I've been able to reproduce this on 8.3 without XO involved (just by querying the /host_logs_download endpoint).

                              The only error I can see in xensource.log is at the end of a successful download call:

                              And then the subsequent download stalls without any indication. I will investigate this further but just to confirm, can any of you see these or similar errors in your logs? Do you have occasional successful downloads followed by failures?

                                @andriy.sultanov I'm not seeing any errors after it stalls.

                                One funny thing is that the pool master usually stalls after approximately 135MB and the slave stalls after 230MB
                                /var/log on master is half the size of slave's so that may be why.

                                Another funny thing is that when I tried the slave once more it actually finished the download at 230MB but my subsequent "tar -xf" complained about "gzip: stdin: decompression OK, trailing garbage ignored"
                                And for some reason the files it extracted were 528MB whereas they're 498MB on the server.
                                Maybe that's a matter of my using XFS vs the server's ext3, though.

                                That "successful" download resulted in

                                xapi: [error||307417 :::80||backtrace] Xapi#getResource /host_logs_download R:51bd50ee890d failed with exception Forkhelpers.Subprocess_failed(1)

                                in xensource.log.
                                So it seems to fail to properly close the transfer session most of the time and the file compression seems to be somewhat buggy as well.
                                Maybe those things are related somehow.

                                  I managed to download from master now as well, with the same gzip complaint and the same "Forkhelpers.Subprocess_failed(1)" in the log

                                    Does it fails using directly the xe CLI: xe host-logs-download file-name="/tmp/logs.gz" uuid=<hostuuid>
                                    The host uuid can be any host of the pool. I didn't reproduce yet with 8.3 by there are not many logs on my hosts.

                                      @gthvn1 Yeah, that works.
                                      I can get the logs both from the same host and from the other one in the pool.
