Failed to add zfs to initrd on openSUSE Tumbleweed

[misaka4a92]

System information

Type	Version/Name
Distribution Name	openSUSE
Distribution Version	Tumbleweed-20210311
Linux Kernel	5.11.4-1-default
Architecture	x86_64
ZFS Version	2.0.4-1
SPL Version	2.0.4-1

Describe the problem you're observing

When making initrd, the inclusion of zfs dracut module failed because libgcc_s.so is not under /usr/lib .

The result of locate libgcc_s.so is:

# locate libgcc_s.so
/lib64/libgcc_s.so.1
/usr/lib64/gcc/x86_64-suse-linux/10/libgcc_s.so

The problem might be caused by contrib/dracut/90zfs/module-setup.sh.in in source tree. After editing the path for libgcc_s.so installation in /usr/lib/dracut/modules.d/90zfs/module-setup.sh, this module can be added to initrd.

Describe how to reproduce the problem

executing dracut -f to build the initrd, when adding zfs to initrd, it will fail at dracut-install libgcc_s.so , and zfs module is not included in the initrd.

Include any warning/errors/backtraces from the system logs

dracut-install: ERROR: installing '/usr/lib/gcc/*/*/libgcc_s.so*'
dracut: FAILED: /usr/lib/dracut/dracut-install -D /var/tmp/dracut.ELz0Yb/initramfs -a /usr/lib/gcc/*/*/libgcc_s.so*

I also have this problem with openSUSE Leap 15.2. I'm not sure what the implications are, because it seems like everything functions normally. I have been using ZFS for a while, but recently used a hack to 'fix' this, which is to add a soft link to libgcc_s.so into a nested directory like /usr/lib/gcc/for/zfs/libgcc_s.so.

Can you try the first patch from #12108 (also referenced below)?

Not sure why, but even running with e69792e I'm still having issues. Running dracut with -H in a chroot, I get

dracut: *** Including module: zfs ***
simple
dracut-install: No SOURCE argument given
Usage: dracut-install -D DESTROOTDIR [-r SYSROOTDIR] [OPTION]... -a SOURCE...
or: dracut-install -D DESTROOTDIR [-r SYSROOTDIR] [OPTION]... SOURCE DEST
or: dracut-install -D DESTROOTDIR [-r SYSROOTDIR] [OPTION]... -m KERNELMODULE [KERNELMODULE …]
...
dracut: FAILED: /usr/lib/dracut/dracut-install -D /var/tmp/dracut.7B9HGe/initramfs -a

Which I can fix by commenting out the # Try a simple path first elif so that it tries the suse option first. Oddly,

# echo /usr/lib/libgcc_s.so*
/usr/lib/libgcc_s.so*

So I'm not sure why the script fails to skip that elif.
