Status: Open
Bug Type: Filesystem function related
Operating System: Redhat EL4
PHP Version: 4.4.5
New Comment:
PHP version seems to be irrelevant, but I was forced to choose a
version because of the bug category. I couldn't find the versions I
tried it on (4.3.9, 5.2.0) in the version drop-down.

Description:
------------
disk_total_space, disk_free_space reports wrong total and free space
for NFS-mounted filesystems on RedHat Linux.
This bug seems to be the related to #39520, if not the same. #39520 has
been rated as 'bogus' which I think is a mistake. Please re-consider.
The bug shows on RedHat Linux, but not SuSE Linux. This might
ultimately be considered as a RedHat bug or of the libraries used there,
but other commands (df) that use the statfs system call show the correct
file system size / free space.
It may be argued (like in #39520) that the wrong block size parameter
is used to calculate total or free disk space. strace df -h shows RedHat
and SuSE report different f_frsize, but same f_bsize on the same NFS
share, but df reports the correct size on both.
Reproduce code:
---------------
Test: Mount a NFS share on a RedHat system and on a SuSE Linux system.
1) RedHat 2.6.9-34.EL, 32-bit
[EMAIL PROTECTED] /]# mount -t nfs 10.20.0.178:/dot/oracle_dump /mnt
[EMAIL PROTECTED] /]# df -h
Filesystem Size Used Avail Use% Mounted on
...
10.20.0.178:/dot/oracle_dump 280G 125G 156G 45% /mnt
[EMAIL PROTECTED] /]# /dot/dc/bin/php/bin/php -r
'echo_number_format(disk_total_space("/mnt")) . "\n";'
37,512,204,288 ==> Wrong size, seems to be real size / 8
2) SuSE Linux 9.3 32-bit
suse:/ # mount -t nfs 10.20.0.178:/dot/oracle_dump /mnt
suse:/ # df -h
Filesystem Size Used Avail Use% Mounted on
...
10.20.0.178:/dot/oracle_dump 280G 125G 156G 45% /mnt
suse:/ # php -r 'echo number_format(disk_total_space("/mnt")) . "\n";'
300,097,634,304 ==> Correct.
Expected result:
----------------
I would expect the result to be 300G on both systems.
Actual result:
--------------
Reports 300G on SuSE Linux, around 35G only on RedHat.
