This commmit updates crashDumpMgr in order to add three new parameters
and enhance the existing one.
1. Maximum Files: Added 'max-files' parameter to specify the maximum
number of saved crash dump files. The default value is 4.
2. Maximum Size: Updated the 'max-size' parameter to support
the 'unlimited' value. The default value is 5GiB.
3. Maximum Used: Included 'max-used' parameter to limit the maximum
storage used by saved crash dump files. It supports 'unlimited'
and has a default value of unlimited.
4. Minimum Available: Implemented 'min-available' parameter, enabling
the definition of a minimum available storage threshold on the
crash dump file system. The value is restricted to a minimum of
1GB and defaults to 10%.
These enhancements refine the crash dump management process and
offer more control over storage usage and crash dump file retention.
Story: 2010893
Task: 48676
Test Plan:
1) max-files parameter:
PASS: don't set max-files param. Ensure the default value is used.
Create 5 directories inside /var/crash. Each of them contains
dmesg.<date> and dump.<date>. run the crashDumpMgr script.
Verify:
PASS: the vmcore_first.tar.1.gz is created when the first
directory is read.
PASS: 4 more vmcore_<date>.tar files are created.
PASS: There will be 1 vmcore_first.tar.1.gz and 4
vmcore_<date>.tar inside /var/log/crash.
PASS: There will be one summary file for each direcory:
<date>_dmesg.<date> inside /var/crash
2) max-size parameter
PASS: don't set max-size param. Ensure the default value is used
(5GiB).
PASS: Set a fixed max-size param. Create a dump.<date> file greater
that the max-size param. Run the crashDumpMgr script. Verify
that the crash dump file is not generated and a log
message is displayed.
3) max-used parameter:
PASS: don't set max-used param. Ensure the default value is used
(unlimited).
PASS: Set a fixed max-used param. Create a dump.<date> file that
will generate that the used space is greater that the
max-used param. Run the crashDumpMgr script. Verify that
the crash dump file is not generated, a log message is
displayed and the directory is deleted.
4) min-available parameter:
PASS: don't set min-available param. Ensure the default value is
used (10% of /var/log/crash).
PASS: Set a fixed 'min-available' param. Generate a 'dump.<date>'
file to simulate a situation where the remaining space is
less than the 'min-available' parameter. Run the crashDumpMgr
script and ensure that it does not create the crashdump file,
displays a log message, and deletes the entry.
5) PASS: Since the crashDumpMgr.service file is not being modified,
verify that the script takes the default values.
Note: All tests have also been conducted by generating a kernel panic
and ensuring the crashDumpMgr script follows the correct workflow.
