Have you tried it without the `-X` flag first? According to the manpage this should only be used as a last resort:
Code:
-X      Used with the -F recovery option. Determines whether extreme measures to find a valid txg should take place. This allows the pool to be rolled back to a txg which is no longer guaranteed to be consistent.  Pools                     imported at an inconsistent txg may contain uncorrectable checksum errors. For more details about pool recovery mode, see the -F option, above. WARNING: This option can be extremely hazardous to the health of                     your pool and should only be used as a last resort.
 
I had the exact same issue happen this past weekend, are by chance using a server with a hardware raid card?
I have a SuperMicro with AVAGO MegaRAID. The controller can't bypass to present de disk directly. I audit and found a RAID0 with 1 disk. Over that a RAIDZ mirror with 2 disk/raid0 . I think this the problem.

That sounds like it might be the issue. My setup was a R620 with a PERC710 mini raid card and no passthrough (used several raid0 vdrives to a zfs system).

In my case I'm able to use a perc 310 raid card to pass the disks directly, only issue now is that proxmox is unable to install the efi bootloader in any drive configuration.
