Re: video archive on a microSD card

[Jaegeuk Kim <jaegeuk@kernel.org>]

Hi,

This is caused by no free segment to write data or node blocks.
In both of cases, have you tried file defragmentation?
I'd like to know whether this bug happens in normal cases as well.

Can you provide fsck.f2fs messages?

Thanks,
