QFS problem: Error: mount_samfs: mount() error: Device busy

Question

Hi:
I setup the QFS on my two nodes sun cluster 3.2 environment. Everything works fine. But when i reboot both nodes, the QFS system cann't be mounted. it shows following error:
Error: mount_samfs: mount() error: Device busy
Following is my setup procedure:
*2. Create the mcf file (on both nodes)*
#cd /etc/opt/SUNWsamfs/
#vi mcf
# Equipment Eq Eq Family Device Additional
# Identifier Ord Type Set State Parameters
archive 2 ma archive on shared
/dev/did/dsk/d5s4 20 mm archive on
/dev/did/dsk/d5s3 21 mr archive on
*3. Create the hosts file (on both nodes)*
#cd /etc/opt/SUNWsamfs/
#vi hosts.archive
#HostName NetworkInterface ServerPriority Unused Server
xenon 172.16.0.129 1 0 server
arsenic 172.16.0.130 1 0
*4. modify the /etc/vfstab file (on both nodes)*
#vi /etc/vfstab
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
archive - /archive samfs - no shared,notrace
*5. create the mount point (on both nodes)*
#mkdir /archive
#chmod 755 archive
*6. create the file system (on the server node)*
[root@xenon:/etc/opt/SUNWsamfs #]samd config
Configuring SAM-FS
[root@xenon:/etc/opt/SUNWsamfs #]sammkfs -S -a 64 archive
Building 'archive' will destroy the contents of devices:
/dev/did/dsk/d5s4
/dev/did/dsk/d5s3
Do you wish to continue? [y/N]y
total data kilobytes = 68525248
total data kilobytes free = 68525184
total meta kilobytes = 1044224
total meta kilobytes free = 1043680
*7. mount the file system*
on server side
[root@xenon:/etc/opt/SUNWsamfs #]mount /archive
[root@xenon:/etc/opt/SUNWsamfs #]chown �R oracle:dba /archive
On client side
[root@arsenic:/etc/opt/SUNWsamfs #]mount /archive
mount_samfs: Configuring file system
*8. Create the QFS metadata server (MDS) resource group for high availability.*
From xenon do:
# clresourcetype register SUNW.qfs
# clresourcegroup create -p nodelist=xenon,arsenic archive-rg
# clresource create -t SUNW.qfs -g archive-rg -p QFSFileSystem=/archive archive-rs
# clresourcegroup online -emM archive-rg
Actually, i did not do the step 8 (Create the QFS metadata server (MDS) resource group for high availability).
then i reboot both nodes, the QFS failed to be mounted
I found one doc is related to my problem.
http://sunsolve.sun.com/search/document.do?assetkey=1-25-90055
It suggests to restart the samfs-qfs Resource Group to fix the problem. But the problem is i haven't setup the "samfs-qfs Resource Group ".
How can i do now? any advices?
Many many thanks!

Answer 1

It looks like you have the wrong entries in your hosts.archive file.
On a cluster, these should always reference the clusternode-priv names, e.g.
-bash-3.00# cat hosts.rac_data
pgyruss1 clusternode1-priv 1 0 server
pgyruss2 clusternode2-priv 1 0
These resolve to slight different addresses to the ones you are using and that might be the cause of your problem.
-bash-3.00# getent hosts clusternode1-priv
172.16.4.1 clusternode1-priv
Try that and see if it works. You might have to fiddle about a bit and may need to run "samd config" again.
