"Download System logs" tgz-file does not work
-
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:
- Download starts without estimation but at high speed
- Some Megabytes are downloaded (~180MiB when trying on masterhost while 90MiB on slavehost)
- Download speed suddenly stop an stuck at 0 for some minutes
- Browser considered the download as failed
- 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!

Hi!
We need more info to assist:
- XO commit
- XCP-ng version (and must be up to date)
-
Hi, thanks for your reply.
To your questions:
- XO Commit 3aa36f9
- XCP-ng 8.2.1 LTS with latest updates (updated last saturday)
Regards
-
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 -
@olivierlambert
Same in 8.3 and 37fbb
edit: And in 5.103.1 -
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... -
@stormi can you help on this subject on XCP-NG team side?
-
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 indeed not free of irony
-
@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

@peder No, but let me ping our XAPI developers @gthvn1 and @andriy.sultanov

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:xapi: [debug||6246 HTTPS 10.1.0.100->:::80|get_host_logs_download|xapi_http] Leaving RBAC-handler in xapi_http after: HANDLE_INVALID: [ task;

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.
