Commit Message

Fabian Grünbichler Sept. 22, 2020, 9:14 a.m. UTC
heavily based on/practically forked off iotest 257 for bitmap backups,
but:

- no writes to filter node 'mirror-top' between completion and
finalization, as those seem to deadlock?
- no inclusion of not-yet-available full/top sync modes in combination
with bitmaps
- extra set of reference/test mirrors to verify that writes in parallel
with active mirror work

intentionally keeping copyright and ownership of original test case to
honor provenance.

yes, but also only on tmpfs. ext4, xfs, ZFS all work fine.. the numbers 
for tmpfs vary between runs, each wrong count is sometimes 393216 (256k 
expected + 128k extra), sometimes 458752 (+192k). it's always the dirty 
bitmap used by the mirror job which is 'wrong', not the passed-in sync 
bitmap which verifies correctly. the final mirror results also seem 
correct.

for the first diff hunk (bitmap + never + simulated), we did

- reference mirror #0
- add sync bitmap 'bitmap0'
- do writes to dirty 6 sectors (393216)
- reference mirror #1
- test mirror #1
- bitmap0 still has count 393216
- reference mirror #2
- test mirror #2
-- while that is not yet completed, do 4 more writes
-- bitmap0 now has count 393216 + 262144 655360
-- dirty bitmap 'should have' count 262144, but has 458752 or 393216

this is not what actually interests us at this point: how far the mirror 
has progressed does not matter, we just want to see that the writes we 
did while it was ongoing have been reflected in the sync bitmap. so 
unless there is some hunch that this difference in mirroring 'speed' 
between the file systems is something that we need to take a look at, 
I'd say we just dump bitmap0 after the writes have been performed, 
instead of all bitmaps (in line 230f).

I see.  The active bitmap the backup job adds isn’t cleared when
progress is made (it’s only used to capture dirtying writes while the
job runs, so the initial bitmap stays constant), in contrast to the one
that mirror adds.  Backup doesn’t clear any bitmap, because it doesn’t
need to – a single iteration is sufficient to catch everything that was
dirty at the beginning of the job.

So, yes, we should hide dirty_bitmap, as it can be in an arbitrary state
while the mirror job is running, and it doesn’t give us useful information.

Looks like there is never any other bitmap bit bitmap0 and the mirror’s
dirty_bitmap, so this sounds like a good idea.
