Xsan: How to automount StorNext volumes

Summary

This article describes the configuration of Xsan clients running Xsan 1.4.1 and earlier to automount filesystems hosted by Quantum StorNext Metadata Controllers. Perform these steps for each Xsan client that should mount a StorNext filesystem at startup.

To configure automounting of StorNext filesystems on Xsan 1.4.2 or later, please refer to instructions in the StorNext installation guide for your version of StorNext available at the Quantum web site.

Products Affected

Xsan 1.1, Xsan 1.2, Xsan 1.3, Xsan 1.4

Ensure the StorNext filesystem will mount on the Xsan clients by following these steps.
Run this command to create a directory to hold the Startup Item files:
```
$ sudo mkdir -m 755 /Library/StartupItems/acfsMounter
```
Using these guidelines, create a new file named "StartupParameters.plist".
Paste these contents into the file:
{ Description = "ACFS File System Mounter"; Provides = ("acfsMounter"); OrderPreference = "Early"; }
Save the file, and put it here:
/Library/StartupItems/acfsMounter
Using these guidelines, create a new file named "acfsMounter".

Paste these contents into the file, replacing [myVolume1 and myVolume2] (on the ninth and tenth lines of the script) with the name of your StorNext volumes. Additional volumes may be entered on the consecutive lines but must be included in the single quotes:

#!/bin/sh 
# 
# CVFSMounter startup script for: 
# 
#       MacOS 
. /etc/rc.common

myVolumes='
myVolume1
myVolume2
'

StartService () 
{
        local vol
        sleep 60
        ConsoleMessage "Mounting ACFS File System" 
        for vol in $myVolumes; do
                if [ -d "/Volumes/${VOL.EN_US}" ]; then 
                        ConsoleMessage "Mountpoint already exists! Ensure that you are not mounting the volume on a preexisting mount!" 
                else 
                        [ ! -e "/Volumes/${VOL.EN_US}" ] && mkdir -m 111 "/Volumes/${VOL.EN_US}" 
                        [ -d "/Volumes/${VOL.EN_US}" ] && mount -t acfs "${VOL.EN_US}" "/Volumes/${VOL.EN_US}" 
                        /usr/sbin/disktool -r > /dev/null 
                fi 
        done
} 
StopService () 
{ 
        local vol
        for vol in $myVolumes; do
                ConsoleMessage "Unmounting ACFS File System" 
                /sbin/umount "/Volumes/${VOL.EN_US}" 
                /usr/sbin/disktool -r > /dev/null 
        done
} 
RestartService () 
{ 
        StopService 
        StartService 
} 
RunService "$1"

Save the file, and put it here:
```
/Library/StartupItems/acfsMounter
```

In the Terminal, execute these commands:

$ sudo chown -R root:wheel /Library/StartupItems/acfsMounter 
$ sudo chmod 755 /Library/StartupItems/acfsMounter/acfsMounter
$ sudo chmod 644 /Library/StartupItems/acfsMounter/StartupParameters.plist
