To keep this post short, I only pasted the errors from the trace below.

The /dev/zfs file does exist

# ll /dev/zfs
crw-rw-rw- 1 root root 10, 249 Jan  9 16:48 /dev/zfs

 

In addition the trace also contains the following, confirming the existence of the file

faccessat(AT_FDCWD, "/dev/zfs", F_OK)   = 0

 

zpool also has the same issue.
