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. 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 ?

I've got now :
nfs_mount_options = soft,nosharecache,rsize=32768,wsize=32768,noatime
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.

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
