Hello there.
After updating to 1.5.2v i faced strange issue. Pool is not imported after system startup at the end. Only command "zpool import -a" will help. But every time do that, is a little annoying. The system it self started (very fast startup) from PCIe SSD (Samsung SM951), the os is 10.9.5 (13F1911). The pool is two mirrored 3TB SAS HGST Drives and one 120GB SSD as Cache device on ATTO ESAS H608 HBA.
What to do to make auto import again??
