Hi guys,<br>
<br>
I remember asking the same thing a couple of weeks ago. Itamar answered<br>
to be the same, should check the vdsm.conf file for nfs mount options.<br>
Because I did not had the time to do test this until now, I return with<br>
the test results.<br>
<br>
Well Alex it seems to be right, on the 3.1 version, if you go and edit<br>
the /etc/vdsm/vdsm.conf file, on line 146, I uncommented the<br>
nfs_mount_options parameter and changed it to :<br>
<br>
nfs_mount_options = soft,nosharecache,noatime,<u></u>rsize=8192,wsize=8192<br>
<br>
Went in Ovirt interface, put the node from Hosts tab into Maintenance,<br>
so that the ISO domain and Master Domain will get unmounted<br>
automatically; restarted the vdsm service on the hypervisior server and<br>
activate the node back from GUI. Upon mount command, there is no change<br>
or difference between what I have added and what was configured<br>
automatically before.<br>

<br>
I remember something about you must not pass any nfs option from ovirt, or it will override the vdsm.conf.<br>
are you trying to set nfs options from both engine and vdsm.conf?<br>
</blockquote></div>
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.<br>
<br>
Must mention, I test on 3.1 version from dreyou's repo.<div class="HOEnZb"><div class="h5"><br>

Might this be a bug on vdsm to be fixed ?<br>

So I've tried some bits Itamar asked me to - however, still get the<br>
same mount options shown.<br>
<br>
I tried "service vdsmd reconfigure; service vdsmd restart" - the mount<br>
for HV03:/vmfs/data should now have the new mount options, but no luck.<br>
<br>
Anyone time to help ?<br>

I've got now :<br>
<br>
nfs_mount_options = soft,nosharecache,rsize=32768,<u></u>wsize=32768,noatime<br>
<br>
<br>
However, when I check the mounts on the host, it does not show<br>
these addtitional options used ? (only soft,nosharecache), here<br>
the mount output:<br>
<br>
HV02:/vmfs/data.old2 on /rhev/data-center/mnt/HV02:_<u></u>vmfs_data.old2<br>
type nfs<br>
(rw,soft,nosharecache,timeo=<u></u>600,retrans=6,nfsvers=3,addr=<u></u>x.x.x8)<br>
HV02:/vmfs/data on /rhev/data-center/mnt/HV02:_<u></u>vmfs_data type nfs<br>
(rw,soft,nosharecache,timeo=<u></u>600,retrans=6,vers=3,addr=x.x.<u></u>x8)<br>
HV03:/vmfs/data on /rhev/data-center/mnt/HV03:_<u></u>vmfs_data type nfs<br>
(rw,soft,nosharecache,timeo=<u></u>600,retrans=6,nfsvers=3,addr=<u></u>127.0.0.1)<br>
<br>
Above is after I restarted HV03 so it really should have mounted<br>
HV03:/vmfs/data with the new options<br>
<br>
another question would be if "nolock" would be a good idea as it<br>
seems that nfs ops are sometimes being blocked by a lock ? at<br>
least, it behaves as if .. i havent further investigated yet.<br>

you can set it manually on each hypervisor by using vdsm.conf.<br>
<br>
add the following into /etc/vdsm/vdsm.conf<br>
<br>
[irs]<br>
nfs_mount_options = soft,nosharecache<br>
<br>
restart vdsmd service on the end.<br>
<br>
<br>
you can also set them via a posixfs storage domain, but for<br>
nfs, an nfs storage domain is recommended over a posixfs one.<br>
question is what is the use case for them, and should they be<br>
added for nfs domains as well.<br>

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