+++ This bug was initially created as a clone of Bug #1852619 +++ Description of problem: Sometimes (rarely) must-gather creates empty files: [root@dell-r640-004 ~]# ls -la nodes/worker-0/lscpu -rw-r--r--. 1 root root 0 Jun 30 14:29 nodes/worker-0/lscpu Version-Release number of selected component (if applicable): # oc version Client Version: 4.4.10 Server Version: 4.4.10 must-gather image: "url": "https://access.redhat.com/containers/#/registry.access.redhat.com/openshift4/performance-addon-operator-must-gather-rhel8/images/v4.4.0-6" --- Additional comment from Francesco Romani on 2020-07-01 09:34:06 UTC --- (In reply to Denys Shchedrivyi from comment #0) > Description of problem: > Sometimes (rarely) must-gather creates empty files: > > [root@dell-r640-004 ~]# ls -la nodes/worker-0/lscpu > -rw-r--r--. 1 root root 0 Jun 30 14:29 nodes/worker-0/lscpu > > > Version-Release number of selected component (if applicable): > # oc version > Client Version: 4.4.10 > Server Version: 4.4.10 > > must-gather image: > "url": > "https://access.redhat.com/containers/#/registry.access.redhat.com/ > openshift4/performance-addon-operator-must-gather-rhel8/images/v4.4.0-6" How often does this happen? Say 1 in 10 times, 1 in 5, 1 in 20? --- Additional comment from Denys Shchedrivyi on 2020-07-02 13:52:50 UTC --- hm, I can't reproduce issue with empty files, but I see another behavior: on every 3-4 runs it does not collect lscpu, lspci and proc_cmdline files for some of worker nodes: # ls -la nodes/worker-0 total 96876 drwxr-xr-x. 2 root root 81 Jul 2 09:48 . drwxr-xr-x. 10 root root 159 Jul 2 09:48 .. -rw-r--r--. 1 root root 198 Jul 2 09:47 lscpu -rw-r--r--. 1 root root 36451 Jul 2 09:47 lspci -rw-r--r--. 1 root root 347 Jul 2 09:47 proc_cmdline -rw-r--r--. 1 root root 99155968 Jul 2 09:48 worker-0_logs_kubelet # ls -la nodes/worker-1 total 110368 drwxr-xr-x. 2 root root 35 Jul 2 09:48 . drwxr-xr-x. 10 root root 159 Jul 2 09:48 .. -rw-r--r--. 1 root root 113016832 Jul 2 09:48 worker-1_logs_kubelet
