ext4 support is missing in 2.6.24 kernel ?

[xagaba]

Hi to all !

Today I install the PVE in my server using an esata disk (for PVE) and an existing 10Tb raid5 md0 device formated in ext4 as additional storage shared with NFS for networked machines and VMs.

Testing the default kernel, I see that 2.6.18 has ext4 support, and after installing the mdadm package I can mount the md0 device.
But the 2.6.24 kernel don't have the ext4 module available and I can't mount the md0 device.
Ext4 module It's missing on purpose in 2.6.24 ?
The ext4 support in 2.6.18 kernel it's back-ported, or it's a early ext4 module version (ext4dev) ?
I'm afraid to use an ext4 version to buggy for my data.... previously mounted in a Ubuntu 10.4 LTS with no problem.

I test also the 2.6.32 kernel (ext4 support it's present), but I'm interested in using OpenVZ containers together with KVM.

Thanks in advance for the replies !

It is backported - but I don't think it is production ready (I would not use it, because it is too new).

I test also the 2.6.32 kernel (ext4 support it's present), but I'm interested in using OpenVZ containers together with KVM.

We are currently testing 2.6.32 with OpenVZ support - there are still some bugs, but hopefully we can release something soon.

Ok, I try to stay with KVM until you release the OpenVZ support for 2.6.32 kernel

See you.
