From: puciek at gmail dot com Operating system: Centos, Gentoo, Ubuntu PHP version: 5.4.17 Package: Filesystem function related Bug Type: Bug Bug description:disk_total_space doesn't work with LVM
Description: ------------ Running disk_total_space on a system that is using LVM it will return completely incorrect data. For example on a machine with result of "df -h" as follows: Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg-vg_root 99G 47G 47G 50% / tmpfs 32G 0 32G 0% /dev/shm /dev/sda1 194M 65M 120M 36% /boot /dev/mapper/vg-vg_backup 400G 33M 400G 1% /var/tmp /dev/mapper/vg-vg_mysql 950G 81G 870G 9% /data on this setup it will always return 32G. We get similar result on second machine with "df -h": Filesystem Size Used Avail Use% Mounted on /dev/mapper/batty-root 258G 217G 29G 89% / none 4.0G 208K 4.0G 1% /dev none 4.0G 0 4.0G 0% /dev/shm none 4.0G 88K 4.0G 1% /var/run none 4.0G 0 4.0G 0% /var/lock none 4.0G 0 4.0G 0% /lib/init/rw none 258G 217G 29G 89% /var/lib/ureadahead/debugfs where it will always return 4G. At first that it was because of outdated version of PHP, original tests were with PHP version 5.3.27 and 5.3.6, but then I was able to reproduce it on my testing box with Gentoo and PHP 5.4.17. -- Edit bug report at https://bugs.php.net/bug.php?id=65446&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=65446&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=65446&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=65446&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=65446&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=65446&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=65446&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=65446&r=needscript Try newer version: https://bugs.php.net/fix.php?id=65446&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=65446&r=support Expected behavior: https://bugs.php.net/fix.php?id=65446&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=65446&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=65446&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=65446&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=65446&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=65446&r=dst IIS Stability: https://bugs.php.net/fix.php?id=65446&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=65446&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=65446&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=65446&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=65446&r=mysqlcfg
