RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Lukas Herbolt 2016-10-14 07:51:44 UTC 
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.

Comment 13 Bohdan Milar 2018-01-18 10:15:43 UTC 
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.

Comment 16 Bohdan Milar 2018-02-08 18:07:26 UTC 
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.
