[solved] mkinitcpio, zfs: module not found: zlib_deflate

I just upgraded to 4.10.2 along with the corresponding zfs-linux/spl-linux updates from the archzfs repo.   mkinitcpio also upgraded to 23-1.

When mkinitcpio runs, I'm getting an error that zlib-deflate module is missing.   Before I reboot and risk needing to pull out my archiso usb, I'm hoping someone may understand what is going on. 

I believe this is related to the zfs hook I am including, but am unsure if this is going to result in a fatal boot issue.  When I first upgraded to kernel 4.10.1 I do not recall seeing this, but it is possible I didn't pay close enough attention.

I can see that there is no zlib_deflate module in the lib area, but there is a header at zlib/deflate.h.  Also I do see that the modules are gzip'd.

/lib/modules/4.10.2-1-ARCH/build/include/config/ppp/deflate.h
/lib/modules/4.10.2-1-ARCH/build/include/config/crypto/deflate.h

Has anyone else using zfs run into this?

@blahhumbug not sure if you've solved it yet, but yes, it will be an issue at boot, as I'm currently trying to solve it

it would be nice if my luck would let me access that link Scimmia posted though

The error is benign, and you will be able to boot just fine.  The error message will be hidden when the linked bug is resolved.  Marking thread solved.

@blahhumbug

I would like some help then....

I have rebooted, and my system has not started properly. when I boot trough USB and chroot into it I get the following

[root@archiso linux-4.10.3]# mkinitcpio -p linux

[root@archiso linux-4.10.3]#

I'm currently trying to build zlib_deflate module, but it's been years since I've compiled my own kernel (and even back then I'd mostly build what I needed embedded), so I'm having trouble getting the .ko file (assuming I actually need it?)

Not really sure where to go from here or what I should be doing

Re: [solved] mkinitcpio, zfs: module not found: zlib_deflate

I don't think any boot issues are related to the zlib_deflate error.   I still get that error everytime I rerun mkinitcpio, but can boot fine.

Did you just upgrade from 4.10.2 to 4.10.3?  Is it possible that 4.10.3 has some other issue with your hardware?

Re: [solved] mkinitcpio, zfs: module not found: zlib_deflate

It's possible...
I haven't been lucky lately.... 2 drives of my ZFS array died recently... 1 is throwing errors....

Thanks for confirming you can still boot fine even with that 'zlib_deflate' error, that saves me a lot of troubleshooting
