The entire process was not seamless, we had to do an entire cluster shutdown and startup to get the cluster up and running again after the upgrade. In the end the cluster was running again, but we ran into some problems with NFS.\n \nThe Problem:\nOur Hypervisors (ACCEPTANCE) can't connect to the back-end Nutanix SR's after the upgrade, resulting in offline\/frozen VMs because their VHDs are not available\/reachable.\n \nWhen rebooting the XenServer hosts they take a very log time to rejoin the farm because they can't connect to the attached SR.\nWhen I do a REPAIR on the SR it also takes a long time before it fails.\nWhen I scan or re-attach the storage via the XenCenter GUI it also fails.\n\n* No advanced options specified (never needed before).\n\n\nWhen I mount manually from the XenServer CLI using the command below, I get the following output;","url":"\/archive-44\/nfs-sr-connectivity-issue-xenserver-7-1-ce-2018-05-0-iptables-30939?postid=35467#post35467","creationDate":"2018-09-26T08:57:09+0000","relativeCreationDate":"3 years ago"},"numberOfViews":9,"contentType":"question","publicLabel":"","category":{"url":"\/archive-43","categoryId":43,"title":"Archive","metaRobots":"index, follow","type":0},"lastPostId":"35479"}, "isActivityPage": true, "showUnsubscribeBtn": null, "attachmentCdn": "https:\/\/uploads-us-west-2.insided.com\/nutanix-us\/attachment\/", "isGuest": true, "csrfToken": "5538255048b7c8e0684595b3d2743d7dfb50fe8d", "hideCategoryMetadata": false, "phrases": { "Forum": { "thread.unsubscribe": "Unsubscribe", "vraag": "Question", "beantwoord": "Solved" } } }">
