recompile kernel on esx server

Jump to solution

Hi,

It's all in the subject line. I have been trying to figure out a way to get a storage device to hold my ISOs an back-up VMs. I want to mount it to the ESX server. However there is the nasty 2G limit I am running into the ESX server when using Samba for the mount type. I have no other choice except to use this type of a mount. So, research tells me that recompiling the kernel with some kind of "fix" will allow me to move past this roadblock. Okay, so my question is: has anyone done this? What were the results? Any suggestions?

Thanks, Jen

You simply can't recompile the VMkernel.

In theory you can recompile the Service Console kernel - provided you have the right build environment.

Anyway this wouldn't help, since the Service Console is limited to 800MB memory.

Why don't you use a VM, mount it there and export it via NFS to the kernel.

This is not a really good solution but is at least a workaround until you have a better storage.

Why must you use samba? What's wrong with NFS?

You will not patch and recompile the vmkernel.

Hi Jae,

NFS is not an option. What is the danger of recompiling the kernel? It shouldn't disturb anything (I think).

try cifs module instead for remote mounts.

iirc, someone posted an updated version - just search the forum

Hi,

Love to search the posts, but with the upgrade cannot figure how to search anymore.... Hope I don't look too dumb but I have to admit I can't figure it out.

Okay thanks everyone. I found the search _. Also found the link to the modified (but working) icfs rpms. I am installing them now. For those of you who don't want to search for it and have been reading my post: http://89.105.41.70/sites/esx/default.aspx

Everything went well with the added kernel module. I did have to run these commands that I copied from the post where I found the http link:

prompt> rpm -i --nodeps kernel-module-cifs-2.4.21-37.0.2.ELvmnix-1.45-1.i386.rpm

prompt> cp -r /lib/modules/2.4.21-37.0.2.ELvmnix/kernel/fs/cifs /lib/modules/2.4.21-47.0.1.ELvmnix/kernel/fs

prompt> depmod -av 2.4.21-47.0.1.ELvmnix/

prompt> mount -t cifs storage_device /mount_point

the other samba rpm went in with no fiddling at all.

Very happy about this --Jen
