I am looking for GlusterFS and GFS(Red Hat Global File system) to set up
shared database storage. I am confused some thing.Now i am writting this in
some assumption but i am not clear my assumption is correct or not . in
case any thing wrong please guide me .Thanks for your time .
We have five socail web sites ,we are using MySQL to store user profile
. Now we are currently using NFS to meet data sharing requirement (for each
site with a single NFS server with its own local storage connected to a
number of clients on network).For Example : Let us assume A ,B,C,D,E are
our sites and NFS1,NFS2,NFS3,NFS4,NFS5 are five NFS server .If a user search
in site A it seraches only NFS1 only but i want to make it to serach on all
servers.storage scalability , high performance can't bet achived in current
NFS set up.The sucess of our bussness requires 100% availability ,
scalability ,high performance ,data sharing for our web serving
To find solution for those requirement i am looking cluster file system to
setup test environment for that .I am new to both networking and cluster
file system but i am familer with Linux.
I saw GlusterFS and GFS .Finaly i took GlusterFS installed one two machines
,it works fine .but yesterday i found one forum ,there somebody is telling
1).GFS/OCFS is about sharing the block device.
2).NFS/PNFS/GlusterFS is about sharing the filesystem (and DRBD seems like a
nice solution to replicate block devices)
now my question is
1). what is the difference between sharing file system and sharing block
device? which one is best for shared data base storage .
2).How do compare GlusterFS and GFS?
3).Is any one can recomand which one is best for our above requirement with
4).we are using MyISAM as storage engine, GlusterFS can support it? Is
there any relevent document related to MySQl with GlustterFS? i googled it
,but badly i am not get relavent information.
5).I have 8 machine for testing perpose ,but i have installed only two
machine only ,one for GlusterFG server and GlusterFS client on another
machine .using clien volume file i am mounted /var/dir from server to client
. Here i have two issue what is the job of GlusterFS Server and GlusterFS
6).Next i want to install GlusterFS server on 5 machine with own local
storage and GlusterFS client on one machine,then i want to mount different
directories from server to one client machine . Is it correct way?
7). mysql default path is /var/lib/mysql/ . how do i mount this directory
to client? can i mount like normal directory?
Please can any one help me.
Thanks to your time
