https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250770 --- Comment #5 from Gunther Schadow <raj@gusw.net> --- Thank you so much for the feedback. I am up over 10 hours now. So it looks like the spell has finally been broken! So, it may well be that the minorversion=1 is necessary for the oneopenown to work. I suggest updating the man page. It currently reads: minorversion=<value> Override the default of 0 for the minor version of the NFS Version 4 protocol. The only minor version currently supported is 1. This option is only meaningful when used 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 OpenOwners, 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 version 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. 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 lack of clear and conspiciously placed documentation and warning. This week, if nothing 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. -- You are receiving this mail because: You are the assignee for the bug.
