Great.
So, carry_on_level() returned ENOMEM, leaving things in inconsistent state.
And for some reasons it happened silently.
Please, check you partition once in a while (weekly or monthly), if
possible.
Thanks,
Edward.

I used this patch on top of reiser4-for-4.9.patch and I have not been
able to reproduce corruption on OOM that I had before.
I tested with writing to multiple disks and partitions while
deactivating swap and filling the RAM.
I had loads of errors in logs (none R4 related) but no errors when I
fsck-ed R4 partitions.
Thanks

Hi Dushan,
Could you please apply this patch and try to reproduce
the corruption with swap turned off?

So what about data corruption?
Did you encounter it after enabling swap?
Nо.
I just fsck-ed my R4 partitions to check and had no corruptions even
as I had disk full a couple of times on some of them in last weeks.

Edward.
This happens without any memory pressure, with 4G of 8G RAM free and
no swap activity.
I reproduced it on freshly booted system.

I spoke prematurely.
Looks like I had 2 different BUGs on mount:
1. BUG when mounting partition with old disk format - that was
solved
with 4.8.1 patch
2. BUG when mounting dismounted partition - this one is not
solved
When I I get this BUG I do:
echo 1 > /proc/sys/vm/drop_caches
and everything works OK again.
With echo 1 > /proc/sys/vm/drop_caches added before mount to
scripts
that I run daily on R4 partitions I had no occurence of this bug
and
before I had it every day.
When partitions are mounted on boot they mount OK, but when
system
finishes booting when I try to mount them I get this BUG:
