Re: [Users] custom nfs mount options

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.

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 ? Alex.
