[Ocfs-users] Observations

[Varghese Abraham]

Hi,
 we have a 2 node / 3 node RAC installation with OCFS.
We have the following observations.


1. TIME STAMP Issue 

We have noticed that the time stamp which is shown on the datafiles doesnt remain the same even after a shutdown normal /shutdown immediate

i.e If I shutdown all RAC instances ( A , B , C) using shutdown normal / immediate, the timestamp on the datafiles are not the same.
 Even If I just bring up one node ( Say A ) and shut it down normally, after doing an Alter system checkpoint,
 I still dont see same time stamp on all the datafiles.

(  I did an alter system checkpoint on a non-rac database and I noticed that all the datafiles changed the time stamp to the current timestamp)

Is this expected behaviour from a RAC database on OCFS. ?


2. COPY / FTP Issue

 We tried to clone from a RAC to a NON-RAC database using a cold backup of the RAC Instance.
 On once occasion  we used simple copy command (cp)  to copy the files over to ext3 disk
 On the second occasion we used ftp command in bin mode to ftp the files over to the destination node to ext3 disk.

On both occassions while creating the new control file on Target node, we got error stating the System file needs more recovery. ( Althoug we are 100% sure that on both occassions databases were shutdown normally for the backup)
 
On both above mentioned ocassions we were able to correct the problem using cp --o_direct command to copy the files over.
When we used cp --o_direct , we were able to create the Target Database successfully.

Has anyone noticed any similar issue with copy / ftp. ?
