Hi,
GlusterFS exports a file system. Once mounted, it works as like local hard
disk, like NFS. So there is no relationship between MyISAM and GlusterFS. And
you can definitely mount GlusterFS volume to /var/lib/mysql, though I
recommened to mount it somewhere else and configure mysql to that directory.
This answers (4) and (7).
For (5) and (6), GlusterFS server exports volumes while GlusterFS client mount
these volumes and does the replication/stripping. Client controls how
stripping/replication is done. Be aware of this. So for (6), you can export
both /export, /export/subexport1 and /export/subexport2 on the server to achive
this.
For (1), (2) and (3), better try yourself. To me, GFS configuration is not
something I would like to try. It's just too complex, IMHO.
Regards,
Yang Ye

Subject: [Gluster-devel] Re :Confusion GlusterFS over GFS(Global File system)
Dear all,
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 infrastrusture.
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)
link :
http://kerneltrap.org/node/6814
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
some reson?
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 client?
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
