Ext4 support for RHEL4


Hello,
I have a system running RedHat enterprise 4.8 in the company I work.

For backup purposes we decided to attach a USB drive previously formatted as ext4. The problem is that the OS did not recognize the partition. Looking into it I found that the kernel (2.6.9-89.ELsmp) does not support ext4.

I can not format and upgrade the OS because the system is compiled for RH4, besides it is in production.
The solution would be re-format the USB drive, but I would like to avoid that.

The question is, is there any other way to add ext4 support to my RHEL4.8? Such as installing an rpm with the module or something else? As you see I am not an expert.

Thanks in advance,
Manuel

I agree. That's the solution.

I do not know whether an elegant method exists to get RHEL4 to handle ext4 filesystems. But I'm fairly certain you will be going into unsupported territory with Red Hat. (i.e. They're not going to help if/when you break things.)

Rather than mucking about with a production system in this way, I recommend formatting the USB drive. Simple and low risk.

Short answer, no.

It could work to mount it under FUSE ext4fuse or ext4fuse.

Thank you all for the replies. I think I will do the safest, formatting the USB drive.
Regards,
Manu
