I have some chanches to recover my data?

If I am reading that zpool import information correctly, you have a 3 disk STRIPED pool. This is a type of ZFS pool that has no redundancy.

Unless you can get your missing disk back to health, you have very little chance of getting any data off the pool.


The disk you've listed, appears to be a Seagate Cheetah 15K.5 146GB Hard Drive. It is possible that you can shutdown and power off everything, re-seat the failed drive's data & power cables, then power the whole system up again. That may or may not work.

If not, and the data is worth a lot, you can try a data recovery service.

If not, and the data is worth a lot, you can try a data recovery service.

I'm guessing the data isn't worth that much since the pool is labeled "test".

EDIT: NVM, I got confused by the illumos link. I just noticed on the post it says MAM3STORAGE.
