Description of problem: Original we use "NLM_GRACE_PERIOD" to define the NLM Grace-time in RHEL6. And in RHEL7, this can be done by setting the RPCNFSDARGS in /etc/sysconfig/nfs file. But I have tried using both of the above methods, it always shows up as "0" when check with "sysctl fs.nfs.nlm_grace_period". Version-Release number of selected component (if applicable): RHEL-7.1 with nfs-utils-1.3.0-0.8.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1. set NLM time in /etc/sysconfig/nfs, maybe using: a. echo "NLM_GRACE_PERIOD=30" >>/etc/sysconfig/nfs b. echo "RPCNFSDARGS='-G 30'" >>/etc/sysconfig/nfs 2. service nfs-config restart 3. service nfs restart 4. sysctl fs.nfs.nlm_grace_period Actual results: [root@hp-dl580g7-04 ~]# sysctl fs.nfs.nlm_grace_period fs.nfs.nlm_grace_period = 0 Expected results: [root@hp-dl580g7-04 ~]# sysctl fs.nfs.nlm_grace_period fs.nfs.nlm_grace_period = 30 Additional info: The NFSv4 grace-time can be set successfully: [root@hp-dl580g7-04 ~]# cat /proc/fs/nfsd/nfsv4gracetime 30
Still reproduced with latest RHEL-7.2 [root@hp-dl585g7-04 ~]# rpm -q kernel kernel-3.10.0-327.13.1.el7.x86_64 [root@hp-dl585g7-04 ~]# rpm -q nfs-utils nfs-utils-1.3.0-0.21.el7_2.x86_64 [root@hp-dl585g7-04 ~]# echo "NLM_GRACE_PERIOD=30" >/etc/sysconfig/nfs [root@hp-dl585g7-04 ~]# echo "RPCNFSDARGS='-G 30'" >>/etc/sysconfig/nfs [root@hp-dl585g7-04 ~]# cat /etc/sysconfig/nfs NLM_GRACE_PERIOD=30 RPCNFSDARGS='-G 30' [root@hp-dl585g7-04 ~]# systemctl restart nfs-config [root@hp-dl585g7-04 ~]# systemctl restart nfs [root@hp-dl585g7-04 ~]# sysctl fs.nfs.nlm_grace_period fs.nfs.nlm_grace_period = 0 [root@hp-dl585g7-04 ~]#

Note there is a modification adding lockd.conf to set module parameters (bug 1264387) in nfs-utils-1.3.0-0.26.el7 Maybe we should set this parameter in /etc/modprob.d/lockd.conf. If so, need update the testcase/manpage. Will do some more investigation later.
