NFS version 4 changing export properties

junioras400 — Thu, 06 Jan 2011 21:30:30 +0000

Hi, can someone describe which will be the impact when i will change the NFS Export Properties to NFSv4 (see Advanced – NFS version supported for connections) and what about the security options? Should i unexport the folder before making the change? NFSv4 will impact the user’s access to shared item? Thanks for your Help.

NFS mount as persistent or as a service?

ITKE — Tue, 15 Dec 2009 17:37:53 +0000

I’m running Windows Server 2008 R2, 64bit. We have a couple NFS shares on our NetApp SAN that we need to mount from this server as letter drives. I have installed “Service for NFS” and I have successfully mounted the NFS shares using both “mount” and “net use”, but I have a couple questions:

1. Is one method better than the other, “mount” vs. “net use”
2. When using “mount,” the mounts are lost when log out of that user
or restart. Can I do any sort of a “persistent” tag with “mount” (I got it to work with “net use”, but this leds into my next question…)
3. Ultimately I would like to have the NFS mounts remain active even
when there is no user logged in, is there any way to mount an NFS share as a service or somthing like that so that it is always available?

Any help would be greatly appreciated, thanks!

Can’t copy from NFS share to NFS share

Looking for help with a an NFS issue

I have two shares one with zfs filesystem the other with a UFS filesystem shared via NFS. I use the shares as home directories for my users

The ZFS has the following in dfstab running on solaris 10
share -F nfs -o anon=0,log /mypool/home

The UFS has the following in dfstab running on solaris 10
share -F nfs -o rw,root=172.16.51.3:172.16.50.3 /usr/home

THese shares are both mounted to two seperate servers running solaris 8

server A @ — /usr/home (/usr/home)
— /usr/tester (/mypool/home)

Server B @ — /usr/home (/usr/home)
— /usr/tester (/mypool/home)

The problem I am having is as root user on server A

    I can ‘touch’ a file, cat, cp, vi, and etc in /usr/tester
    I can not do any of the above to my /usr/home

When I go to Server B the problem is just the opposite

    I can ‘touch’ a file, cat, cp, vi, and etc in /usr/home
    I can not do any of the above to my /usr/tester

I was alerted to this problem when I tried to do a usermod -d /usr/tester -m
    I recieved permissions errors when coping the contents from usr/home to /usr/tester on server A

drwxr-xr-x 9603 root root 9603 Oct 3 19:05 tester
drwxr-xr-x 9602 root root 185856 Oct 5 12:07 home

Has anyone else experienced this problem before? What did you do to resolve it. Not sure of what other information is needed.

Regards,

Looking for multi-vendor Storage Virtualization

GuruBhai — Fri, 06 Feb 2009 09:47:44 +0000

Need a “simple concept” to do the SAN Interconnect based Storage virtualization on multi vendor basis / heterogeneous SAN sub system based. And how much this will be helpful on ROI?

Throughput calculator for all the SAN subsystem?

GuruBhai — Fri, 06 Feb 2009 09:43:47 +0000

I was searching for a long time for a simple tool which can tell us the controller throughput of any SAN environment. Its necessary for every Storage engineer to have this utility to cross verify the subsystem we buy. Ofcourse the vendor will have the tool or LAB benchmark for the same. But those will work on the connected environments – I mean the san subsystem connected with multiple nodes with File system etc. Instead of that we should have a tool which helps us to find out the exact back end performance of the controller. Even its single or dual on SAN path. Does anyone have any idea on the same. Incase of more clarification let me know. We can discuss further and we can create something new for the storage industry. What say?

How do I setup a storage with multiple geographical location Sync?

GuruBhai — Thu, 05 Feb 2009 15:36:47 +0000

Iam planning to setup a storage which needs to be located in 5 geographical locations. The data which i write on the first location should get sysnc with rest 4 locations in no time. I dont want to invest more in procure higher bandwidth solutions. Is there any other way to sync the data by caching mechanism or related to same technique. The ens result would not only the data sync I require the data to get video streamed or rendered using same applications on all location. I wont specifically select the data from locations. I just select stream or render what ever mount points I have. Cause I dont want to show the location to the end user. He will not come to know which location data he is accessing. But end of the day I require minimum 4GBps of throughput on each storage location. Will it be possible by just configuring same kind of storage hardware on all locations with same LUN size & file systems export. User will have access either through NFS or FTP. Does anyone have idea on this?

mooving SUN NFS v3 to EMC Celera NFS v3

Mimo — Tue, 03 Feb 2009 16:00:45 +0000

We are actualy in a big migration project. and we want to migrate are multiple single file systems to a EMC Celera NAS. Are problèmes is that we use ACL on are SUN FS. and when we copy the file using Rsynck (i’m a SAN architect I don’t know a clue of unix systems and command) with all th good attribute to copy the ACL with it. the copy won’t work. EMC don’t seem to support ACL in his NAS. Toes any one here had this issue and how did you fixe it.

Are SUN os is SUN 8.0
Are Celera OS version is Dart 5.5
