Hello,

two things to check:

a.) Does the disk you want to transfer to have enought space?
b.) Does the target filesystem support "large" files (i.e. >2 GB)?

how can i check file system support large files?

are we speaking about linux?

if so, all moder fs (ext3, reiserfs, ...) support >2GB files

AFAIK, even ext2 with 2.4 kernel supports big files.

But I suggest you to split you archive anyway - probably some applications don't support big files

Rgds,
Vitaly

I have both, ext3 and ext2 with kernel 2.4 but ftp cant send archives more than 2 GB.

Hello Edwin,

one way to make sure your file system supports that large files and has enough space is to create a file larger 2GB. One easy way to do so is

dd if=/dev/zero of=test.dat count=450000

Don't forget to remove test.dat after the test ;-)

Greetings, Martin

P.S. Creating the 2GB file takes a moment...

Hi,

this certainly looks like the 2^31-1 = 2147483647 bytes limit.

I know the Filesystem can support it, as well as the OS, so this leaves the FTP server and client.

Try using something else, i.e. ncftp to rule out the client, or using a different protocol all together (you have ssh? use 'scp').

or 'split' and 'join' the file in 2Gb chunks.

I get this information when i run

dd if=/dev/zero of=test.dat count=450000

[root@salato-apl11 TIS]# dd if=/dev/zero of=test.dat count=450000
450000+0 records in
450000+0 records out

Is it that ok?

Hello Edwin,

definitly, this proofs you do have enough space on the disk and the filesystem supports files >2GB conclusively. So now the next think to check/exchange is the ftp client/server as already suggested by others. Make sure you remove the test.dat or you will waste 2GB of disk space ;-)

All the best,

Martin
