I'm running 14.04 LTS with ZFS and tried to update my kernel to 3.17 following these instructions. During this install I got this error:

    *** Please make sure the kmod spl devel <kernel> package for your
    *** distribution is installed then try again.  If that fails you
    *** can specify the location of the spl objects with the
    *** '--with-spl-obj=PATH' option.

Google led me to this page, and I ran sudo apt-get install spl-dkms to attempt to fix the above.

After reboot, I have kernel 3.17 but no ZFS pools. I rolled back to my previous kernel (3.13.0-40) but still have no zpools.

$ sudo zpool status
no pools available

I should have one mirror pool showing. The partitions are still there, as parted shows:

(parted) print                                                            
Model: ATA HGST HTS721010A9 (scsi)
Disk /dev/sda: 1000GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt

Number  Start   End     Size    File system  Name    Flags
 1      1049kB  2097kB  1049kB               boot0   bios_grub
 2      2097kB  10.0GB  9998MB               root0
 3      10.0GB  992GB   982GB   zfs          zdata0
 5      992GB   1000GB  8204MB               swap0

The other drive looks similar. The mirror is on zdata0 and zdata1.

Why can't it find my zpool, and how do I get it back?

In this case, zdb showed the pool, but zpool status did not. I needed to do:

zpool import -f zdata

And all was well again.
