System information

Type Broken Version/Name
Distribution Name Arch Linux
Distribution Version Rolling release (current as of Apr-06-2018)
Linux Kernel 4.15.15-1-ARCH #1 SMP PREEMPT Sat Mar 31 23:59:25 UTC 2018
Architecture x86_64 on i7-4770K
ZFS Version 0.7.0-405_g533ea0415
SPL Version 0.7.0-32_g581bc01
ZFS Package Version 2018.04.04.r3402.533ea0415.4.15.15.1-1
SPL Package Version 2018.04.04.r1070.581bc01.4.15.15.1-1

Describe the problem you're observing

After the upstream encryption change (as experienced in #7175), I've since migrated to new pools, but a recent upgrade made the FS not mountable. I can import the pool fine, load the keys fine, but not mount the actual FS. I am also acutely aware of the silliness of running the development version of ZFS, on Linux, on Arch linux, but let's get past that, shall we?

[root@antares ~]# zpool import tank
[root@antares ~]# zfs load-key tank/multimedia 
Enter passphrase for 'tank/multimedia': 
[root@antares tank]# zfs mount tank/multimedia 
filesystem 'tank/multimedia' can not be mounted: Input/output error
cannot mount 'tank/multimedia': Invalid argument

Describe how to reproduce the problem

Use the above version of the kernel and ZFS, and run the commands above.

For reference, the following combination works fine with this file system (which was created after the encryption update):

Component Known Good Working Version
zfs 0.7.0-316_ge921f6508
spl 0.7.0-26_g48ef8ba
zfs package 2018.02.15.r3313.e921f6508.4.15.3.2-1
spl package 2018.02.07.r1064.48ef8ba.4.15.3.2-1
Linux kernel 4.15.3-2

So changes made after those versions will likely be the culprit, unless the package is built vastly differently.

Include any warning/errors/backtraces from the system logs

Output of /proc/spl/kstat/zfs/dbgmsg attached.
