[ale] fiber channel mounts

[Jeff Lightner]

OCFS or OCFS2?

 

Not arguing - just curious.

With my tests OCFS has less performance/functionalities than GFS when
used without oracle.

	I'm saying while OCFS2 was initially designed for Oracle there
is nothing prohibiting one from using it for other purposes since it is
Open Source (i.e. no cost).

	 

	However, it probably makes more sense to investigate GFS first
if you're not already familiar with OCFS2.

	OCFS2 works very well with oracle...  GFS is a general purpose
clustered filesystem...

		You could get OCFS2 (open source) from Oracle's web
site.  It's designed to allow you to use the same storage in a clustered
configuration.  We use its predecessor OCFS for one of our old Oracle
RAC environments but RAC isn't required as OCFS2 handles its own
clustering setup.  Its also reportedly a much improved product over
OCFS(1).   It uses Linux' O_DIRECT stuff for the file sharing so the
tools you use have to be O_DIRECT aware and I think most of the newer
ones (tar, ls, cp, mv etc...) are.   When we did it back on RHEL3 (2.4
kernel) we had to load the utilities Oracle had made that were (also
open source).

		 

		Also GFS I believe is designed for similar usage and is
native to most distros but I haven't used it.

		I have a netapp joined by fiber channel to 2 linux head
end servers. I'm using multipath fiber channel in an active/active mode
for maximum data throughput.
		
		box 1 can write a file and read that file is there. Box
2 can't see the file exists. 
		box 2 can write file and see it on the netapp but box
one does not see it.
		
		run sync on both boxes and umount/mount the netapp
storage space again.
		both box 1 & 2 see the file written from box 1 but the
file written from box 2 is gone.
		
		this is bad. Clearly I have a misconfiguration
somewhere! Box 2 shows errors related to ext3 journal corruption so ext3
is NOT a good choice.
		
		Box 2 is supposed to be a failover database and the
netapp is the storage for the database files. I would prefer for the
failover to be closer to a hot standby than a cold standby but it looks
like I can't keep the netapp partition mounted on box 2 if box 1 is
still live. I'm not running the database at all on box 2.
