Description of problem:
It reports error while configure kdump failed via NFS.

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

How reproducible:

Steps to Reproduce:
1. Install rhev-hypervisor7-7.1-20150827.1.el7ev
2. Enable network
3. Configure Kdump via NFS type
4. Check #mount
5. Check /etc/kdump.conf file
6. Check the TUI page.

Actual results:
1. After step3. it reports error as follows.
KDump configuration failed, location unreachable. Previous configuration was restored.
2. After step4, it nfs location which I filled is already mounted.
#mount on /run/kdump-nfs type nfs4 (rw,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=,local_lock=none,addr=
3. After step5, NFS location is not saved in /etc/kdump.conf file.
4. After step6, TUI still shows Local as Kdump type.

Expected results:
1. Kdump via NFS should be configured without error.

Comment 2 Ryan Barry 2015-09-01 16:04:21 EDT
I can't reproduce this, and no changes have been made to the kdump code recently. Are you sure this isn't a problem with the environment?
Comment 5 Ryan Barry 2015-09-08 14:28:41 EDT
Still can't reproduce this.

If it's reproducible, can you please let me know the details of a system I can check it on, and the appropriate kdump path?
Comment 9 Ryan Barry 2015-09-11 11:27:15 EDT
It looks like I couldn't reproduce it (and QE didn't hit it earlier), because /var/crash already existed on my NFS share. If it doesn't, kdump now expects that users should create that manually...
Comment 10 Fabian Deutsch 2015-09-22 10:54:18 EDT
Lowering the priority because it happens only if the target dir is missing, and thus only affecting really new installs with non-existent target dirs.
Comment 13 wanghui 2015-10-26 03:21:33 EDT
Test version:

Test steps:
1. Install rhev-hypervisor7-7.2-20151025.0.el7ev
2. Enable network
3. From the remote NFS server, clean the target dir
4. Configure Kdump via NFS type
5. Check #mount
6. Check /etc/kdump.conf file
7. Check the TUI page.

Test result:
1. Kdump can be setup as NFS type succeed.

So this issue is fixed in ovirt-node-3.3.0-0.18.20151022git82dc52c.el7ev.noarch. Change the status to Verified.
