Re: [Linux-cluster] Did you use GFS with witch technology?



Hi,

Ok I understand, that should be supported.

If your problems (freeze, qdisk loose, etc..;) occur when your VMs are under high load (CPU, RAM, disk IOs ?) why don't you configure more VCPUs on your VMs, split the number of VMs accross more LUNs, etc..

 The thing to keep in mind, there is no way under ESX to limit the IO rate per VM, and ESX 3.5 doesn't support multipathing, if the bottleneck is more located on the disk subsystem.

Not,

What I did:

I have 10 virtual machines.

I have one LUN with 200 GB formated by ESX using VMFS.

Inside this lun, I have a lot of small pieces of 10 GB (the "/" os each
one virtual machine) formated by RHEL 5.x using EXT3.

And my GFS was in another LUN, called DRM (some like Direct Raw Mapping)
where the LUN was delivered to VM without pass "inside" of ESX.

Can you understood of I've complicated ever more? :-p
