1339721 – CGroup: /system.slice/mnt.mount not accepting mount options given /etc/fstab for glusterfs.fuse

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 Riyas Abdulrasak 2016-05-25 17:09:35 UTC

Description of problem:

Systemctl mount not setting the mount options specified in /etc/fstab for a gluster.fuse mount.

~~~~~~~~~~~~~~~
systemctl status /mnt
● mnt.mount - /mnt
   Loaded: loaded (/etc/fstab)
   Active: active (mounted) (Result: exit-code) since Wed 2016-05-25 21:20:59 IST; 1min 3s ago
    Where: /mnt
     What: dhcp3-109:/testvol1
     Docs: man:fstab(5)
           man:systemd-fstab-generator(8)
  Process: 3190 ExecRemount=/bin/mount dhcp3-109:/testvol1 /mnt -o remount,defaults,_netdev,acl,ro -n -t glusterfs (code=exited, status=32)
  Process: 3138 ExecMount=/bin/mount dhcp3-109:/testvol1 /mnt -n -t glusterfs -o defaults,_netdev,acl,ro (code=exited, status=0/SUCCESS)
   CGroup: /system.slice/mnt.mount
           └─3171 /usr/sbin/glusterfs --volfile-server=dhcp3-109 --volfile-id=/testvol1 /mnt                  <<<<<<< The mount options some how getting omitted here.

~~~~~~~~~~~~~~~~~~~~~~~~~~
Version-Release number of selected component (if applicable):

Red Hat Enterprise Linux 7.2 (3.10.0-327.el7.x86_64)
systemd-219-19.el7_2.9.x86_64

How reproducible:

Always

Steps to Reproduce:

1. Install RHEL 7.2 

2. Mention a glusterfs share in the /etc/fstab with ro or acl option like below.

dhcp3-109:/testvol1		/mnt			glusterfs	defaults,_netdev,acl,ro	0 0

3. Try to mount the share using 

#systemctl start <mountpoint>

Actual results:

The mount options specified in /etc/fstab  are ignored by "CGroup: /system.slice/mnt.mount"

Expected results:

The mount options should be set as mentioned in fstab

Additional info:

* The mount options were working properly in RHEL 7.1 client , with "systemd-208-20.el7_1.5.x86_64"

* Mount options are properly set when using mount.glusterfs , instead of systemctl.

Comment 2 Mohit Agrawal 2016-05-27 05:14:03 UTC

Hi,

  In RHEL-7.2 mount.glusterfs is not taking argument(passed with -o) because systemd is passing -n(before -o) argument in mount option and script(mount.glusterfs) ignoring the -n option.

The option is obsolete in upstream from the patch(https://github.com/systemd/systemd/pull/755/commits/6f20f850f79df365c2533195214127142013d317) , I think same needs to be merge in downstream also.

Hi Mohit,

what is the next step for this customer ? do we provide an hotfix or a process to have the argument being passed in the correct order ?

Comment 4 Mohit Agrawal 2016-06-04 03:46:35 UTC

Hi,

   I think this is not critical for customer aspect.We can share workaround to configure options with glusterfs by write some unit file to start mount as a separate process.
   For specific to hotfix Riyas can confirm more and for about the backport of patch systemd engineering can confirm.

Regards
Mohit Agrawal
