[PATCH v2 0/8] fstests: add checks for testing zoned btrfs

[PATCH v2 0/8] fstests: add checks for testing zoned btrfs

[Naohiro Aota]

This series revisit my old series to test zoned btrfs [1].

[1] https://lore.kernel.org/fstests/PH0PR04MB7416870032582BC2A8FC5AD99B299@PH0PR04MB7416.namprd04.prod.outlook.com/T/

Several tests are failing on zoned btrfs, but actually they are invalid.
There are two reasons of the failures. One is creating too small
filesystem. Since zoned btrfs needs at lease 5 zones (= 1.25 GB if zone
size = 256MB) to create a filesystem, tests creating e.g., 1 GB filesystem
will fail.

The other reason is lacking of zone support of some dm targets and loop
device. So, they need to skip the test if the testing device is zoned.

Patches 1 to 4 handle the too small file system failure.

And, patches 5 to 8 add checks for tests requiring non-zoned devices.

Naohiro Aota (8):
  common/rc: introduce minimal fs size check
  common/rc: fix blocksize detection for btrfs
  btrfs/057: use _scratch_mkfs_sized to set filesystem size
  fstests: btrfs: add minimal file system size check
  common: add zoned block device checks
  shared/032: add check for zoned block device
  fstests: btrfs: add checks for zoned block device
  fstests: generic: add checks for zoned block device

[PATCH v2 1/8] common/rc: introduce minimal fs size check

[Naohiro Aota]

_scratch_mkfs_sized() create a file system with specified size
limit. It can, however, too small for certain kind of devices. For
example, zoned btrfs requires at least 5 zones to make a file system.

This commit introduces MIN_FSSIZE, which specify the minimum size of the
possible file system. We can set this variable e.g. $ZONE_SIZE *
$MIN_ZONE_COUNT.

[PATCH v2 2/8] common/rc: fix blocksize detection for btrfs

[Naohiro Aota]

Mkfs.btrfs's "-b" does not specify the block size but the file system size.
Use "-s" to detect it instead.

[PATCH v2 3/8] btrfs/057: use _scratch_mkfs_sized to set filesystem size

[Naohiro Aota]

Btrfs/057 is using _scratch_mkfs directly to set filesystem size. This
can be _scratch_mkfs_sized instead, to go through several
checks (e.g., minimal filesystem size check).

[PATCH v2 4/8] fstests: btrfs: add minimal file system size check

[Naohiro Aota]

Some btrfs tests call _scratch_pool_mkfs or _scratch_mkfs by themselves to
specify file system size limit. It slips through the check in
_scratch_mkfs_sized(). Let's add size check call for each of them.

[PATCH v2 5/8] common: add zoned block device checks

[Naohiro Aota]

dm-error and dm-snapshot does not have DM_TARGET_ZONED_HM nor
DM_TARGET_MIXED_ZONED_MODEL feature and does not implement
.report_zones(). So, it cannot pass the zone information from the down
layer (zoned device) to the upper layer.

Loop device also cannot pass the zone information.

This patch requires non-zoned block device for the tests using these
ones.

We should really do the check in _require rules not in _setup()
functions. Please see below.

I think we could move all check here, based on $target, e.g.

	case $target in
	thin-pool|error|snapshot)
		_require_non_zoned_device ${SCRATCH_DEV}
		;;
	esac

[Naohiro Aota]

Mkfs on zoned block device won't work on most filesystem. Let's
disable the test.

[PATCH v2 7/8] fstests: btrfs: add checks for zoned block device

[Naohiro Aota]

Modify btrfs tests to require non-zoned block device or limit some part of
tests not to be run on zone block devices.

Modified tests by the reasons:

* Mixed BG
  - btrfs/011
* Non-single profile
  - btrfs/003
  - btrfs/011
  - btrfs/023
  - btrfs/124
  - btrfs/125
  - btrfs/148
  - btrfs/157
  - btrfs/158
  - btrfs/195
  - btrfs/197
  - btrfs/198
* Convert from ext4
  - btrfs/012
  - btrfs/136
* nodatacow
  - btrfs/236
* inode cache
  - btrfs/049
* space cache (v1)
  - btrfs/131
* write outside of FS code
  - btrfs/116
  - btrfs/140
  - btrfs/215
* verbose output
  - btrfs/194

Same here, some comments to explain why replace doesn't work with zoned
devices?

Yeah, that will make the patch much more simple. Thanks.

[PATCH v2 8/8] fstests: generic: add checks for zoned block device

[Naohiro Aota]

Modify generic tests to require non-zoned block device

generic/108 is disabled on zoned block device because the LVM device not
always aligned to the zone boundary.

generic/471 is disabled because we cannot enable NoCoW on zoned btrfs.

generic/570 is disabled because swap file which require nocow is not usable
on zoned btrfs.

I think in generic/108 and generic/570 we should only check zoned device
if FSTYP is btrfs in in generic/471. And also need comments to explain
the reason to do so.

Thanks,

Hmm, I don't think the FSTYP restriction is neccesary for generic/108
and generic/570.

Generic/108 won't work on zoned devices regardless of file system
type, because it tries to create LVM on SCRATCH_DEV.

Also, generic/570 tries to create swap directly on SCRATCH_DEV. So, no
file system code is related here. And, swap cannot be work on zoned
devices, because it will do random write IOs. My commit log was
misleading on this point.

I'll add comments anyway.

I did a light review of the patches (no actual testing), all seem to be
doing the right thing regarding the special cases zoned mode needs, and
not changing the default use case.

I've applied patch 1-4 and 6.
