dkms does not find kernel source
16,914
After a looong debug session I found that the build and source links in /lib/modules/2.6.32-openvz-042stab090.5-amd64 to /usr/src and /usr/include were missing.
Added them manually and it worked.
Everyime happy that I can work in Linux where I can at least look into the source and debug...

For days now I am trying to get ZFS-on-Linux working on Debian 7 but the module doesn't want to compile:
# dpkg-reconfigure zfs-dkms ------------------------------ Deleting module version: 0.6.3 completely from the DKMS tree. ------------------------------ Done. Loading new zfs-0.6.3 DKMS files... Building only for 2.6.32-openvz-042stab090.5-amd64 Module build for the currently running kernel was skipped since the kernel source for this kernel does not seem to be installed.
Of course, headers and source are installed:
# uname -r 2.6.32-openvz-042stab090.5-amd64 # dpkg -l | grep 2.6.32-openvz-042stab090.5-amd64 ii linux-headers-2.6.32-openvz-042stab090.5-amd64 1 amd64 Header files related to Linux kernel, specifically, ii linux-image-2.6.32-openvz-042stab090.5-amd64 1 amd64 Linux kernel binary image for version 2.6.32-openvz-042stab090.5-amd64 ii linux-source-2.6.32-openvz-042stab090.5-amd64 1 all Linux kernel source for version 2.6.32-openvz-042stab090.5-amd64 #
So I am trying it manually. Still not:
# dkms build zfs/0.6.3 -k `uname -r` --kernelsourcedir=/usr/src/linux-source-2.6.32-openvz-042stab090.5-amd64 Error! Your kernel headers for kernel 2.6.32-openvz-042stab090.5-amd64 cannot be found. Please install the linux-headers-2.6.32-openvz-042stab090.5-amd64 package, or use the --kernelsourcedir option to tell DKMS where it's located ls /usr/src/linux-source-2.6.32-openvz-042stab090.5-amd64 | wc -l 90
it contains everything (arch, block, configs, debian, ...). WTF?

pdwalker about 9 yearsI had a similar problem. I updated the kernel (yum update) and installed the zfs packages. My kernel showed one version, while the sources showed an updated version. Had I rebooted after the update, the zfs installation would have worked. Your hint gave me the required clue

divB about 9 yearsThanks for your comment. I can also add one more thing: At least in Debian it seems to be important to install the linux-headers-* package first before upgrading the kernel (linux-image-*). That way it works for me.
