[LTP] [PATCH 0/3] LVM support scripts for OpenQA

[LTP] [PATCH 0/3] LVM support scripts for OpenQA

[Martin Doucha]

The old support script for LVM tests (testscripts/ltpfslvm.sh) doesn't work
very well with external testing tools so LVM tests currently cannot be run
in OpenQA. Create new LVM support scripts that focus exclusively on setup
and cleanup. One of the scripts also generates a new LVM runfile that'll test
only file systems supported by the test machine.

Martin Doucha (3):
  Fix releasing loop devices in shell API
  Allow acquiring multiple loop devices
  Add LVM support scripts

[LTP] [PATCH 1/3] Fix releasing loop devices in shell API

[Martin Doucha]

tst_device helper program currently cannot release any loop devices because
tst_release_device() checks whether any loop device was acquired by the same
process. If not, it'll do nothing. And since loop devices for shell test
scripts are always acquired by a different tst_device process, the check always
fails.

Call tst_detach_device() instead to bypass the check.

[LTP] [PATCH 2/3] Allow acquiring multiple loop devices

[Martin Doucha]

tst_acquire_device__() currently uses a hardcoded filename so only one loop
device can be used at a time. Allow setting arbitrary temp filename so that
multiple different loop devices can be acquired.

[LTP] [PATCH 3/3] Add LVM support scripts

[Martin Doucha]

Add support scripts for LVM tests that can be used with external testing tools.
- generate_runfile.sh - Creates runtest/lvm.local with testcases for all
  locally supported FS types
- prepare_lvm.sh - Creates 2 LVM volume groups and mounts logical volumes
  for all locally supported FS types

[LTP] [PATCH v2 3/3] Add LVM support scripts

[Martin Doucha]

Add support scripts for LVM tests that can be used with external testing tools.
- generate_lvm_runfile.sh - Creates runtest/lvm.local with testcases for all
  locally supported FS types
- prepare_lvm.sh - Creates 2 LVM volume groups and mounts logical volumes
  for all locally supported FS types
- cleanup_lvm.sh - remove LVM volume groups created by prepare_lvm.sh and
  release the associated loop devices

Signed-off-by: Martin Doucha <mdoucha@suse.cz>
---

Changes since v1:
- rename generate_runfile.sh to generate_lvm_runfile.sh
- update above commit message

[LTP] [PATCH v3 3/3] Add LVM support scripts

[Martin Doucha]

Add support scripts for LVM tests that can be used with external testing tools.
- generate_lvm_runfile.sh - Creates runtest/lvm.local with testcases for all
  locally supported FS types
- prepare_lvm.sh - Creates 2 LVM volume groups and mounts logical volumes
  for all locally supported FS types
- cleanup_lvm.sh - remove LVM volume groups created by prepare_lvm.sh and
  release the associated loop devices

Signed-off-by: Martin Doucha <mdoucha@suse.cz>

Sorry for resubmitting again, I didn't test v2 properly.

Changes since v1:
- rename generate_runfile.sh to generate_lvm_runfile.sh
- update above commit message

Changes since v2:
- fix filename in misc/lvm/Makefile

[LTP] [PATCH v3 3/3] Add LVM support scripts

[Petr Vorel]

Hi Martin,

thanks for fixing these scripts, they were waiting long for it :).

> Changes since v2:
> - fix filename in misc/lvm/Makefile
You can just use *.sh next time.

> +++ b/testcases/misc/lvm/cleanup_lvm.sh
Maybe we can move them to testcases/lvm, but that's tiny detail.

BTW part of the cleanup it'd be nice to get rid of 'export LTPROOT;'

BTW I wonder whether we still need testscripts/ltpfslvm.sh testscripts/ltpfsnolvm.sh,
which use runtest/lvm.part1 and runtest/lvm.part1?


Kind regards,

[LTP] [PATCH 1/3] Fix releasing loop devices in shell API

[Petr Vorel]

Hi Martin,

> tst_device helper program currently cannot release any loop devices because
> tst_release_device() checks whether any loop device was acquired by the same
> process. If not, it'll do nothing. And since loop devices for shell test
> scripts are always acquired by a different tst_device process, the check always

> Call tst_detach_device() instead to bypass the check.

Indeed losetup --list shows increasing list of the devices.
Thanks for a fix, pushed.

Kind regards,
Petr

[LTP] [PATCH 2/3] Allow acquiring multiple loop devices

Hi Martin,

Good idea, thanks!

BTW IMHO DEV_FILE should be #define DEV_FILE "test_dev.%d.img", where %d would
be PID to fix clash when tests run in paralel (e.g. mkswap01.sh and df01.sh).
I'll send a patch tomorrow, based on this one.

Kind regards,

Huh, do we even attempt to support parallel runs at this point? I doubt
so.

No, but I'd expect it'd be nice to have this support for runltp-ng. Or not?

We will fix this, when we get there. Also thinking of it the file that
is backing the device is actually created in the test temporary
directory, which has unique name anyways.

If I remember it correctly, the file was in /tmp directory (the default)
(probably before creating temporary directory and cd into it).
I was really able to crash on tests, when running 2 in paralel.

[LTP] [PATCH v4 3/4] Add LVM support scripts

[Martin Doucha]

Add support scripts for LVM tests that can be used with external testing tools.
- generate_lvm_runfile.sh - Creates runtest/lvm.local with testcases for all
  locally supported FS types
- prepare_lvm.sh - Creates 2 LVM volume groups and mounts logical volumes
  for all locally supported FS types
- cleanup_lvm.sh - remove LVM volume groups created by prepare_lvm.sh and
  release the associated loop devices

[LTP] [PATCH v4 4/4] Skip Btrfs in LVM stress tests

[Martin Doucha]

Delayed file deletion makes stress testing Btrfs on small block devices
difficult. Each test case would require explicit FS cleanup synchronization.
Drop Btrfs tests from LVM runfile for now.
