Red Hat Bugzilla – Bug 1384796
udisk does not clean the mount point during reboot
Last modified: 2018-06-12 22:41:32 EDT
Description of problem: When you change the default location for devices to be mounted under /media via udev rule. --- cat /etc/udev/rules.d/81-udisks2.rules: ENV{ID_FS_USAGE}=="filesystem", ENV{UDISKS_FILESYSTEM_SHARED}="1" --- The mount point '/media/<DEVICE NAME>' which is created by udisk is not removed during reboot. It leads to new directory created '/media/<DEVICE NAME>1' after reboot and mount over udisks. Checking the documentation the folder should be removed by the umount helper umount.udisks2 which will clean the directory. THe helper should be specified in the /etc/mtab as 'helper=' or 'uhelper=' which does not seems to be there. mtab from reproducer: --- /dev/sr0 /media/XRMPOEM_EN iso9660 ro,nosuid,nodev,relatime,uid=0,gid=0,iocharset=utf8,mode=0400,dmode=0500 0 0 --- Current workaround is to set /media as tmpfs. Version-Release number of selected component (if applicable): libudisks2-2.1.2-6.el7.x86_64 udisks2-2.1.2-6.el7.x86_64 How reproducible: Each time while shared disk is mounted under /media with udisks Steps to Reproduce: 1. mount disk with udisks as shared under /media 2. reboot machine Actual results: New directory is created on every reboot /media/<DISKNAME>N where DISKNAME is mounted and the previous old mountpoint remains empty (/media/<DISKNAME>). Expected results: On each reboot the umount (/usr/sbin/umount.udisks2) will clean up the directories created by the udisks. Additional info:

Works fine with labeled disks. But with not labeled disks, UUID is used to create the mount point. UUID mount points still act incorrectly as described earlier: - New directory is created on every reboot /media/<DISKNAME>N where DISKNAME is mounted and the previous old mountpoint remains empty (/media/<DISKNAME>). Tested on x86_64, aarch64, ppc64 with udisks2-2.7.3-4.el7 using image file as a loop device.

Test case updated to cover both - labeled and non-labeled partitions - and to be applicable also on remote systems (to test secondary archs). Tested on x86_64, ppc64, ppc64le, aarch64. Bug reproduced with udisks2-2.7.3-4 (for non-labeled partitions). NOT reproduced with udisks2-2.7.3-6. Fix verified.
