Hi guys,
I remember asking the same thing a couple of weeks ago. Itamar

to be the same, should check the vdsm.conf file for nfs mount
options.
Because I did not had the time to do test this until now, I
return with
the test results.
Well Alex it seems to be right, on the 3.1 version, if you go
and edit
the /etc/vdsm/vdsm.conf file, on line 146, I uncommented the
nfs_mount_options parameter and changed it to :
nfs_mount_options =
soft,nosharecache,noatime,__rsize=8192,wsize=8192
Went in Ovirt interface, put the node from Hosts tab into
Maintenance,
so that the ISO domain and Master Domain will get unmounted
automatically; restarted the vdsm service on the hypervisior
server and
activate the node back from GUI. Upon mount command, there is
no change
or difference between what I have added and what was configured
automatically before.
I remember something about you must not pass any nfs option from
ovirt, or it will override the vdsm.conf.
are you trying to set nfs options from both engine and vdsm.conf?
Basically, I had 2 questions, one was like Alex asked and it is in the
current topic, and the other was suggestion to add these nfs
configuration parameters changes into the GUI in Storage tab. I asked
if besides the retrans, timeo and vers is it possible to add anything
else in the future GUI devel.
Must mention, I test on 3.1 version from dreyou's repo.
This is key. There was a bug where vdsm did not take the vdsm.conf
nfs_mount_options into consideration [1], which was fixed upstream in
4.10.1--so after the version you are running. There was also a
complementary patch in engine--the two work together to fix this issue.
If you had the fix, you would simply need to be sure to not check the
"Override Default Options" checkbox for your NFS storage in the UI.
However, without the fix, I think the most straightforward way to
accomplish what you want is to configure the storage using a Posix domain
as Itamar suggested earlier in the thread.
I'll leave the question of adding additional, custom parameters in the UI
for others to answer. Seems like it could be useful, but can be
accomplished other ways.
[1] http://bugzilla.redhat.com/826921
type nfs
(rw,soft,nosharecache,timeo=__10,retrans=6,vers=4,addr=x.x.__x.x,clientaddr=x.x.x.x)
Might this be a bug on vdsm to be fixed ?

So I've tried some bits Itamar asked me to - however,

I tried "service vdsmd reconfigure; service vdsmd restart"
- the mount
for HV03:/vmfs/data should now have the new mount options,
but no luck.
Anyone time to help ?

the mount output:

Above is after I restarted HV03 so it really should
have mounted
HV03:/vmfs/data with the new options
another question would be if "nolock" would be a good
idea as it
seems that nfs ops are sometimes being blocked by a
lock ? at
least, it behaves as if .. i havent further
investigated yet.

you can set it manually on each hypervisor by

add the following into /etc/vdsm/vdsm.conf

nfs_mount_options = soft,nosharecache
restart vdsmd service on the end.
you can also set them via a posixfs storage
domain, but for
nfs, an nfs storage domain is recommended over a
posixfs one.
question is what is the use case for them, and
should they be
added for nfs domains as well.

Subject: [Users] custom nfs mount options
Hi,
Is it possible set custom nfs mount options,
specifically : noatime,
wsize and rsize ? I couldnt see anything
when "adding
a NFS domain"
- only timeout & retry.
Thanks!
