Hi,
Since I had some free time over Christmas, I decided to conduct few
tests over btrFS to se how it will cope with "real life storage" for
normal "gray users" and I've found that filesystem will always mess up
your files that are larger than 10GB.
Hi Tom,
I'd like to nail down the test case a little better.
1) Create on one drive, fill with data
2) Add a second drive, convert to raid1
3) find corruptions?
What happens if you start with two drives in raid1? In other words, I'm
trying to see if this is a problem with the conversion code.

Ok, my description might be a bit enigmatic so to cut long story short
tests are:
1) create a single drive default btrfs volume on single partition ->
fill with test data -> scrub -> admire errors.
2) create a raid1 (-d raid1 -m raid1) volume with two partitions on
separate disk, each same size etc. -> fill with test data -> scrub ->
admire errors.
3) create a raid10 (-d raid10 -m raid1) volume with four partitions on
separate disk, each same size etc. -> fill with test data -> scrub ->
admire errors.
all disks are same age + size + model ... two different batches to avoid
same time failure.
