I asked if besides the retrans, timeo and vers is it possible to add anything else in the future GUI devel.

Hi guys,
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.
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?
Must mention, I test on 3.1 version from dreyou's repo.
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, still get the
same mount options shown.
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 ?

However, when I check the mounts on the host, it does not show
these addtitional options used ? (only soft,nosharecache), here
the mount output:
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)
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)
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)
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 using vdsm.conf.
add the following into /etc/vdsm/vdsm.conf
[irs]
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!
Alex
