Description Branislav Náter 2016-04-06 14:51:21 UTC
Reproduced also on sos-3.2-35.el7

+++ This bug was initially created as a clone of Bug #1324535 +++

Description of problem:
When using lvmdump=on (or lvmdump-am=on) options from lvm2 plugin, expected data are not collected.

Version-Release number of selected component (if applicable):
sos-3.2-40.el6

How reproducible:
always

Steps to Reproduce:
1. sosreport -o lvm2 --tmp-dir=. --batch -k lvm2.lvmdump=on

Actual results:
no data in sos_commands/lvm2/lvmdump/ directory

Expected results:
Expected data are present

Additional info:

When running lvmdump command and providing directory where to dump data (using -d <dirname> switch), directory should not exists. Otherwise lvmdump exits with error: "Fatal: <dirname> already exists"

When running lvmdump in lvm2 plugin, get_cmd_output_path() method from __init__.py is used:

cmd = lvmdump_cmd % (lvmdump_opts,
                             self.get_cmd_output_path(name="lvmdump")) <--------
        self.add_cmd_output(cmd)

This method creates provided directory "lvmdump" and that cause lvmdump command to fails.

Fix is as easy as run get_cmd_output_path() with "make=False" argument to prevent directory creation:

cmd = lvmdump_cmd % (lvmdump_opts,
                             self.get_cmd_output_path(name="lvmdump", make=False)) <--
        self.add_cmd_output(cmd)

FYI the bug is indepentent on using --tmp-dir - reproducer is valid also for:

sosreport -o lvm2 --batch -k lvm2.lvmdump=on

Comment 5 Pavel Moravec 2016-11-11 07:46:01 UTC
This bug has been fixed due to sos rebase to 3.3 [1] that includes the upstream fix. Relevant RHEL7.3 sos errata is [2].

Therefore I am closing the bug. Please test it if it addresses the reported problem properly, and if not, reopne the BZ.
