Exporting File System with Root Access to Another System

[Sheila Birchmeier]

We have been hearing discussion that if a file system is exported (in the control file for the package) with root privileges to another system (example: XFS[1]="-o access=servers, root=serverxx") and serverxx is not found in the host table that the package will not start successfully. Does anyone know if this is true?

Sheila,

You may want to open a ticket with HP to get this answered quicker.

Good Luck!

If you specify a line like

XFS[0]="-o aceess=hosts,root=host1 /export/sapmnt/SAP01"

in your NFS control script, and the address of host1 cannot be resolved, the "exportfs -i" command in the package control script function export_fs() will fail with an error (exportfs error: host1: unknown host).

As you can see in the package control script, any error returned by exportfs will prevent the package from starting.:

function export_fs
{
for I in "${XFS[@]}"
do
while :
do
EXPORTERROR=`exportfs -i $I 2>&1`
[...]
if [[ -n "$EXPORTERROR" ]] ; then
print "$EXPORTERROR"
print "\tERROR: Function export_fs"
print "\tERROR: Failed to export $I"
un_export_fs
halt_nfs_services
nfs_defined_halt_cmds
umount_fs
deactivate_volume_group
exit 1
[...]
