#48099 [Com]: stat failed on a readable / writable file in NFS mount
ID: 48099
Comment by: offset at galvanet dot com
Reported By: offset at galvanet dot com
Status: Feedback
Bug Type: Filesystem function related
Operating System: Linux
PHP Version: 5.2.9
New Comment:
It's working with LFS support.
Stat is exactly the same :
stat64(/home/files/3/4/0/340db92364af5c0616187f6e1db86ed7,
{st_mode=S_IFREG|0444, st_size=9888768, ...}) = 0
But after the size is writen correctly :
write(1, 9888768, 79888768) = 7
(Working on a 32bit system)
Thanks

As I don't have any NFS mounted stuff available anywhere, can you try
this:
# CFLAGS=`getconf LFS_CFLAGS` ./config.nice
# make clean make
And then try that script of yours.

This might be related to ug #45040 (And LFS support in general..)
