Hi,
I'm testing with some multipart uploads to RGW and I'm hitting a problem
when trying to upload files larger then 1159MB.
The tool I'm using is s3cmd 1.5.1
Ceph version: 0.67.4
It's very specific, this is what I tried (after a lot of narrowing down):
$ dd if=/dev/zero of=1159MB.bin bs=1024k count=1159
$ dd if=/dev/zero of=1160MB.bin bs=1024k count=1160
$ s3cmd put -P 1159MB.bin s3://widodh/1159MB.bin
$ s3cmd put -P 1160MB.bin s3://widodh/1160MB.bin
The 1159MB file works, the 1160MB fails with:
Reading through the source I wasn't able to figure out what err_no=27 means.
Error code 27 is EFBIG, which is "File too large", but searching for
'27' or 'EFBIG' in the source code doesn't show me anything.
In the end of the logs it shows:

I tried a lot of sizes, but the tipping point seems to be 1159MB,
anything larger won't work.
Playing with the multipart chunk size doesn't make a difference.
Without multipart (--disable-multipart) the upload succeeds, but a
2500MB non-multipart upload fails again with the same error code.
Any ideas?
