[Moosefs-users] how to export moosefs to vmware esxi

From: youngcow <you...@gm...> - 2011-02-13 01:38:12

Hi
  I build a moosefs storage to my application. Now I meet a problem
about it. I have a vmware ESXi 4 system and I want ESXi use the moosefs
storage.
  I found ESXi support nfs. Then I build a file server which mount
moosefs file system. But Linux kernel nfs server can't export no-local
file system. I install unfs which is a user space nfs server. But I find
a problem , Unfs dosen't support nfs feature "readdirplus" and ESXi 4
uses it. It's very big problem for me. Anyone can help me ?

Thanks.

Thanks.
That's a good idea. I will try it later.
But I wonder the performance of the big file on mfs.

Today I find the GlusterFS implement native NFS.
I think they have find this problem of unfsd (it used unfsd before).

I hope MFS can have native NFS support.

I have test the solution of iscsi.
I use iscsitarget-1.4.20.2 and install on rhel 5.5 x64. I make a 
file(size 80G on mfs) and share with 2 node ESXi4 but only one ESXi4 can 
use it (VMFS) another ESXi4 can see the lun but it can't use it.

Then I make another file (size 4G) on normal filesystem(ext3 local) and 
share to these machines and two ESXi4 nodes can use it.

I can;t understand these, anyone know the reason ?

Thanks.

the config file is

cat /etc/iet/ietd.conf
User userid superpassword
Target iqn.2011-02.cn.thcic.storage:storage.vmiso
Lun 0 Path=/data/iscsi/vmiso,Type=fileio
Lun 1 Path=/home/data/myiso,Type=fileio


vmiso(lun 0) is on mfs and myiso(lun 1) on ext3.

MFS has chunk lock when writing, may be it's the reason.

You could use NFS server over iSCSI, then export it to ESXi4 VM.

Hi

     When I use one file on ext3 file system, It worked very well. So I 
think it's a problem of moosefs. But I don't know the reason.
