What is this vdsm-4.9.6-4.5.x86_64 build? where's vdsm.log? Have you tried this in more than one mountpoint in one host? What happens when you add a completly silly option (say, "danken")? Does it show in vdsm.log and mount command? Created attachment 588813 [details]
vdsm log
vdsm-4.9.6-4.5.x86_64 is vdsm that comes with si4 build. vdsm log added. I tried this on more than one mountpoint. vdsm daemon was restarted after each change in vdsm.conf file. iiuc - nfs options from backend should override vdsm.conf (In reply to comment #7) > iiuc - nfs options from backend should override vdsm.conf Correct, but if not passed from backend need to take from conf. Need release note to specify that vdsm.conf param is deprecated and will be ignored in the future.

Just to be clear, the deprecated parameter is: [irs] nfs_mount_options = soft,nosharecache,vers=3 It will be supported in 3.x, but will probably be removed in 4.0 Customers using it should upgrade domains to > V2 and set the params from the GUI

Changes pushed: http://gerrit.ovirt.org/5368 The proposed patch checks for matching keys on a per-option basis, but does not do any "intelligent" option resolution. E.g. the following option combinations will be resolved: engine | vdsm.conf | resulting option ------------------------------------------- timeo=600 | timeo=1000 | timeo=600 <nothing> | vers=3 | vers=3 soft | hard | soft,hard (can't do this!) (This is all done within the context of a longer option string, so combinations like "vers=3,intr" would do what you expect subject to the above rules.)
