So it looks like the spell has finally been brok= en! So, it may well be that the minorversion=3D1 is necessary for the oneopenow= n to work. I suggest updating the man page. It currently reads: minorversion=3D Override the default of 0 for the minor version of the NFS Version 4 protocol. The only minor version curren= tly supported is 1. This option is only meaningful when u= sed with the nfsv4 option. oneopenown Make a minor version 1 of the NFS Version 4 protocol mount use a single OpenOwner for all Opens. This may = be useful for a server with a very low limit on OpenOwner= s, such as AmazonEFS. It can only be used with an NFSv4.1 mount. It may not work correctly when Delegations are being issued by a server, but note that the AmazonEFS server does not issued delegations at this time. pnfs Enable support for parallel NFS (pNFS) for minor versi= on 1 of the NFS Version 4 protocol. This option is only meaningful when used with the minorversion option. The clear statement of pnfs "This option is only meaningful when used with = the minorversion option." would remove all ambiguity. I do wonder also about the speed compared to a "native" Amazon Linux mount = -t efs mount. I feel like it's slower. My throughput allocation utilization is barely a blip, not an issue for me.= =20 I personally can't really use your efs automounter because I need to be in precise control of the mount /usr during boot. I wonder if more improvements can be gleaned from the mount_efs Linux code. Anyway, it looks more and more like this is a no-bug and just somehow a lac= k of clear and conspiciously placed documentation and warning. This week, if not= hing else fails, I will close this issue and I will update all the places where I had left some negative commments. I love FreeBSD after all. Thank you. --=20 You are receiving this mail because: You are the assignee for the bug.=
