Re: Large file size issues with Samba client.
After patching Samba 2.2.3 and the 2.4.18 kernel with your patchs and I can now access files 2GB without issue. Just for kicks I downloaded 2.5.24 and that worked too (without patching the kernel). Guess smbfs lfs is included. For now though I'm running 2.4.18 just to be safe. Thanks.

Large file size issues with Samba client.

RE: Large file size issues with Samba client.
Title: RE: Large file size issues with Samba client. An 18.4 Exabyte realmedia file? Must be one of Jeremy Allison's ACL discussions. That number is interesting. If you subtract it from 2^64, you get 1,932,534,103. If that number is added to the other reported file size (2,307,064*1024), the result is 343 bytes less than 2^32. The 343 bytes is explained by rounding in the bytes-to-kilobytes conversion being done in W2K. My guess is, somewhere, the actual 32-bit unsigned file size is being reported as a 32 bit signed number. That negative value is later represented as a 64-bit signed number, and is later represented an unsigned 64-bit number. That series of representation changes would convert the just-over 2GB file size into the just-under MAXINT64 size being shown in Linux. -Original Message- From: Brett Simpson [mailto:[EMAIL PROTECTED]] Sent: Thursday, June 20, 2002 1:01 PM To: [EMAIL PROTECTED] Subject: Large file size issues with Samba client.

Thanks. I'll give that a try.

It was a pain to test due to the lack of sparse file support on the Linux side (I had not seen an equivalent to the sparse flag on the Linux side - but it sure helps on the Windows side in creating test files). What lack of sparse file support? $ dd if=/dev/zero of=aa bs=512 count=1 seek=1024 1+0 records in 1+0 records out $ d aa -rw-rw-r--1 puw puw524800 Jun 21 03:26 aa $ du -h aa 8.0kaa There is no flag because it is always supported (given filesystem backing, and all unix-like filesystems support it). Just truncate it to the size you want it to be. /Urban
