Subject: Overlay issue when truncating files over 2G
Date: Fri, 11 Sep 2015 11:05:06 +0300	[thread overview]
Message-ID: <55F28B32.7000001@gmail.com> (raw)

Hi, I think I've found an issue with overlay. Steps to reproduce:

# cd $(mktemp -d)
# mkdir lower upper work root
# truncate -s 3G lower/sparse
# mount -t overlay -o workdir=work,upperdir=upper,lowerdir=lower overlay 
work
# truncate -s 0 work/sparse
truncate: cannot open ‘work/sparse’ for writing: Value too large for 
defined data type

# umount work

My kernel is: 3.19.0-26-generic #28~14.04.1-Ubuntu SMP

Thanks,
Alkis Georgopoulos
