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 JianHong Yin 2016-11-18 09:15:30 UTC 
Description of problem:

As Subject/Summary:
'exportfs -s' always output some exports options twice

[yjh@dhcp-11-111 nfs-utils.up]$ sudo systemctl start nfs
[yjh@dhcp-11-111 nfs-utils.up]$ sudo exportfs -s 
/expdir  *(rw,wdelay,no_root_squash,no_subtree_check,sec=sys,rw,secure,no_root_squash,no_all_squash)

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

How reproducible:
always

Steps to Reproduce:
$ cat /etc/exports
/expdir   *(rw,sync,no_root_squash)
$ sudo systemctl start nfs
$ sudo exportfs -s
/expdir  *(rw,wdelay,no_root_squash,no_subtree_check,sec=sys,rw,secure,no_root_squash,no_all_squash)

Actual results:
exportfs -s output some exports options twice, but can not output some options like sync,hide,no_wdlay

Expected results:
remove redundant options, and add the missing options

Comment 2 ChunYu Wang 2017-02-07 12:18:58 UTC 
Hi, Steve,

Patch in Comment 1 provided by Jianhong seems workable to solve this problem, will we fix it in next versions?


Also, some opitions appear twice in /var/lib/nfs/etab:
-bash-4.3# strace exportfs -s 2>&1 |fgrep "etab"
open("/var/lib/nfs/.etab.lock", O_RDONLY|O_CREAT, 0600) = 3
open("/var/lib/nfs/etab", O_RDONLY)     = 4

[chunwang@fs-qe ~]$ cat /var/lib/nfs/etab | head -1 | sed 's/^.*(//;s/)//;s/,/\n/g' |sort
acl
anongid=65534
anonuid=65534
hide
no_all_squash
no_all_squash
nocrossmnt
no_pnfs
