ok, thanks a lot for your fast answer ... i plan on testing it also on top of gfs2 in the near future and i'll see if i'll have the same behavior or not ..

Just out of curiosity, what does the " mainmem.usenamedfile="FALSE" " parameter means, from a vmware server point of view ?

vmware is creating a virtual memory file on start (.vmem) and using mmap() system call for accessing it, and ocfs doesn`t support mmap system call.
if that parameter is set to false, that file isn`t created in the VM`s directory, but in a different way in the local temp directory. (you don`t see it there because it`s unlinked/deleted after creation).

Thanks a lot devzero ! I was setting up the same thing : two ibm blades with CentOS 5.1 x86_64 with VMware server 1.0.4 using a iScsi shared disk with ocfs2 on top.

I had the same problem as described above and your tip did the job .. Just out of curiosity, what does the " mainmem.usenamedfile="FALSE" " parameter means, from a vmware server point of view ?

Just for info (and hoping that google indexes this as well .. ) , here is the info i had before applying the tip :

VMServerd IPC closed the connection with thread /path/to/my.vmx (0x8301af0)
Feb 29 10:54:20: app| Lost connection to /path/to/my.vmx (/path/to/my.vmx) unexpectedly.

Only problem so far is when I place the vmx file on the ocfs2 storage,
then when starting the image, vmware crashes.

try setting mainmem.usenamedfile="FALSE" in your VM`s configuration

Hi Jon,

I am using the vmware server on x blades with Linux on it.
Attached to the blades we have an emc storage which we mounted on all blades with ocfs2.
The .vmdk files are placed on the ocfs2 filesystem, so we can switch vm to each blade depending performance.
Also I use a seperate vm which connects to the other vm's and syncs the datadisks to a backup datadisk using rsync. That way I have a uptime of 24 hours.

Only problem so far is when I place the vmx file on the ocfs2 storage, then when starting the image, vmware crashes.

using rhel4 as host and ubuntu 704 as client

ocfs2 on OpenSuse 10.2

Hello,
I am wondering if anyone is using ocfs2 for a shared storage solution with VMWare Server. I have successfully installed it using guest os opensuse 10.2 accessing a shared disk from 2 guests. Seems to work fine and is fairly easy to configure.

What I would like to do is use ocfs on multiple vmware server hosts and shared storage for a low cost solution using opensuse 10.2 and ocfs2 on fiberchannel storage.

VMWare server seems to work fine on opensuse 10.2

This would facilitate a low cost esx solution that vmfs provides to esx on fiberchannel.

Thanks,

Jon
