Missing kernel modules in 8.3?

F

frijsdijk

Today, by coincidence, I spotted a weird issue on a couple of our FreeBSD servers that are running 8.3-RELEASE. All these servers are running the GENERIC kernel (amd64), all of them are updated with freebsd-update.

In /boot/kernel, I'm missing opensolaris.ko. Upon investigation, I found that alot more modules are missing.

If I compare the files in /boot/kernel, from a good server (1252 files), with a 'bad' server (~1070 files), I'm missing these kernel modules:

Has anyone else spotted something like this? The weird thing is, zfs.ko is there, but opensolaris.ko is not. Needless to say, zfs will not start on such a machine.

I could easily fix it by copying /boot/kernel from a good to a bad machine, but this got me a bit worried. Something like this should not happen!
 
Code: 
# kldload zfs
kldload: can't load zfs: Exec format error

And in /var/log/messages:

Code: 
Nov  6 11:29:38 srv01 kernel: KLD zfs.ko: depends on opensolaris - not available or version mismatch
Nov  6 11:29:38 srv01 kernel: linker_load_file: Unsupported file type

Code: 
# zfs list
internal error: failed to initialize ZFS library

# /etc/rc.d/zfs onestart
kldload: can't load zfs: Exec format error
/etc/rc.d/zfs: WARNING: Unable to load kernel module zfs

Weird. I think maybe you should also post to the mailing lists.

So if I understood this correctly, those servers were pre-8.3 and were updated using freebsd-update. Can it be that the modules were missing before the update?

Possibly.. yes. Not sure about that.

On one machiene I rsync'd the /boot/kernel from a good machine. And then I can start ZFS.

Code: 
# kldstat
Id Refs Address            Size     Name
 1   11 0xffffffff80100000 e56e68   kernel
 2    1 0xffffffff81012000 bd6f     ipfw.ko
 3    1 0xffffffff8101e000 6e1b     ipmi.ko
 4    1 0xffffffff81025000 88f      smbus.ko
# kldload zfs
# kldstat

Old modules that are no longer rebuilt because of entries in /etc/src.conf?

Non-existent on this server. But the server is maintained with freebsd-update (running GENERIC kernel). So how could that be the reason?
