Hi guys,<br>
<br>
I remember asking the same thing a couple of weeks ago. Itamar
answered 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.<br>
<br>
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 :<br>
<br>
nfs_mount_options =
soft,nosharecache,noatime,rsize=8192,wsize=8192<br>
<br>
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.<br>
<br>
type nfs
(rw,soft,nosharecache,timeo=10,retrans=6,vers=4,addr=x.x.x.x,clientaddr=x.x.x.x)<br>
<br>
Might this be a bug on vdsm to be fixed ?<br>
<br>

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

nfs_mount_options =

<br>
<br>

However, when I check the mounts on the host, it does
not show these addtitional options used ? (only
soft,nosharecache), here the mount output: <br>
<br>
HV02:/vmfs/data.old2 on
/rhev/data-center/mnt/HV02:_vmfs_data.old2 type nfs
(rw,soft,nosharecache,timeo=600,retrans=6,nfsvers=3,addr=x.x.x8)<br>
HV02:/vmfs/data on
/rhev/data-center/mnt/HV02:_vmfs_data type nfs
(rw,soft,nosharecache,timeo=600,retrans=6,vers=3,addr=x.x.x8)<br>
HV03:/vmfs/data on
/rhev/data-center/mnt/HV03:_vmfs_data type nfs
(rw,soft,nosharecache,timeo=600,retrans=6,nfsvers=3,addr=127.0.0.1)<br>
<br>
</div>
<div>Above is after I restarted HV03 so it really should
have mounted HV03:/vmfs/data with the new options<br>
<br>
</div>
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. <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>

you can also set them via a posixfs storage
domain, but for 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 added for nfs domains as well.

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