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
