If anyone cares besides me, I found these limits with x86: Vanilla 2.4.20 kernel 2 TB With LBD kernel patch -- Effectively None. ie. Multiple PBs or bigger Vanilla 2.6.0 kernel with LBD_CONFIG off 2 TB With LBD_CONFIG ON -- Effectively None. ie. Multiple PBs or bigger XFS -- Effectively None. ie. Multiple PBs or bigger DM -- 2 TB even in 2.6 (not sure about this) LVM -- 1 PB, but you requires large extents NFS -- No restriction Samba -- No restriction. Also, the actual hardware driver (SCSI, etc.) can limit to 2 TB, or even 1 TB. Greg On Fri, 2003-10-17 at 17:07, Greg Freemyer wrote:

For Large file systems use XFS from SGI. I have files that are 65 Gig in size.

Hi,
I have Suse 7.3 with kernel 2.4.19 compiled by my own, and i want to create a 5GB file.
I use the command:
dd if=/dev/zero of=largefile bs=1024k count=5120
and this is the answer that i get:
dd: writing `largefile': File too large 2049+0 records in 2048+0 records out
ls -h
2.0G largefile
I try as root and as normal user.
How can i create this file under Linux?
