Yes, i think you are right, I noticed that swift is trying to generate
log file with size more that 18446744073GB, which cause the file two
large problem.

for a normal execution of first.swift code, it will will generate the
files as follow;
[torqueuser at ip-10-251-89-208 test]$ pwd
/mnt/ebs/test
[torqueuser at ip-10-251-89-208 test]$ ls -l
-rw-rw-r-- 1 torqueuser torqueuser 25141 May 29 12:33
first-20090529-1233-nj1nazbf.log
-rw-rw-r-- 1 torqueuser torqueuser 25406 May 29 12:34
first-20090529-1234-bgzd13z4.log
-rw-rw-r-- 1 torqueuser torqueuser 14 May 29 12:34 hello.txt
-rw-rw-r-- 1 torqueuser torqueuser 114 May 29 12:34 swift.log
but when I try to run it on s3 (mounted via s3-fuse), the error occurs
is following files is generated:
[torqueuser at ip-10-251-89-208 abc]$ pwd
/mnt/s3/abc
[torqueuser at ip-10-251-89-208 abc]$ ls -l
total 2

no output of 'quota', 'df'is (/mnt/s3 is the s3 directory :
[torqueuser at ip-10-251-89-208 s3]$ df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda1 4128448 2744188 1174548 71% /
none 873880 0 873880 0% /dev/shm
/dev/sda2 153899044 1999124 144082296 2% /mnt
/dev/sdf 10321208 290468 9506452 3% /mnt/ebs
fuse 274877906944 0 274877906944 0% /mnt/s3
normally, we have create a single file sized around 1G with no problem,
it seems there is something wrong when swift try to generate log on
s3fuse. (I am using swift-0.9)
Then I tried to run swift on locally but with output file write to s3
directory, then it works correctly.(log file is stored on local
directory where i run swift, and output file is on s3 directory)
