A little question.
It is possible to make a clustered NFSv4 service equal non clustered configuration like this:
/dev/sda1 ---> shared storage (GFS is not available)
/dev/sdb1 ---> shared storage (GFS is not available)
mkdir -p /fs/{software,video}
mkdir /{software.video}
mount /dev/sda1 /video
mount /dev/sdb1 /software
mount --bind /video /fs/video
mount --bind /software /fs/software
cat /etc/exports ---->
/fs 192.168.1.0/24(rw,nohide,insecure,no_subtree_check,fsid=0)
/fs/video 192.168.1.0/24(rw,nohide,insecure,no_subtree_check)
/fs/software 192.168.1.0/24(rw,nohide,insecure,no_subtree_check)
--->
Attempt to export with RHCS only one directory with fsid=0 was succesfull.
This configuration ( with only one directory export ) works fine:
<resources>
<fs device="/dev/sda1" force_fsck="0" force_unmount="0" fsid="46982" fstype="ext3" mountpoint="/video" name="fs_sda1" options
="" self_fence="0"/>
<ip address="192.168.1.8" monitor_link="1"/>
<nfsexport name="video"/>
<nfsclient name="wc_client" options="rw,insecure,sync,fsid=0,nohide,no_subtree_check" target="192.168.1.0/24"/>
</resources>
<service autostart="1" domain="fs_fail" name="fs_video" recovery="relocate">
<ip ref="192.168.1.8 "/>
<fs ref="fs_sda1">
<nfsexport name="fs_sda1">
<nfsclient ref="wc_client"/>
</nfsexport>
</fs>
</service>
This is my current cluster.conf:
<resources>
<fs device="/dev/sda1" force_fsck="0" force_unmount="0" fsid="46982" fstype="ext3" mountpoint="/video" name="fs_sda1" options
="" self_fence="0"/>
<fs device="/dev/sdb1" force_fsck="0" force_unmount="0" fsid="46983" fstype="ext3" mountpoint="/software" name="fs_sdb1" optio
ns="" self_fence="0"/>
<ip address="192.168.1.8" monitor_link="1"/>
<nfsexport name="/fs"/>
<nfsexport name="video"/>
<nfsexport name="software"/>
<nfsclient name="wc_client_fs" options="rw,insecure,sync,fsid=0,nohide,no_subtree_check" target=" 192.168.1.0/24"/>
<nfsclient name="wc_client_v" options="rw,insecure,sync,nohide,no_subtree_check" target=" 192.168.1.0/24"/>
<nfsclient name="wc_client_s" options="rw,insecure,sync,nohide,no_subtree_check" target="192.168.1.0/24 "/>
</resources>
<service autostart="1" domain="fs_fail" name="fs_video" recovery="relocate">
<ip ref=" 192.168.1.8"/>
<nfsexport ref="/fs">
<nfsclient ref="wc_client_fs"/>
</nfsexport>
<fs ref="fs_sda1">
<nfsexport name="fs_sda1">
<nfsclient ref="wc_client_v"/>
</nfsexport>
</fs>
<fs ref="fs_sdb1">
<nfsexport name="fs_sdb1">
<nfsclient ref="wc_client_s"/>
</nfsexport>
</fs>
</service>
This configuration does not work.
Your assistance will be greatly appreciated.
Thanks.
