Hello,
we start running a FreeNAS-Box with ZFS RAID in mirror-mode with a usb-stick as boot-device. After setting up the raid, the webinterface says that the mirror was setup correctly and it´s "healthy".
After that we checked the functionality in case of a hardware failure - we shutted down the system and plugged off one of the disks. After booting up, the raid was degraded, as expected, but all data was still available from the nas. Afterwards we shutted the system down again, replugged the first hdd and plugged the other drive off. Know we expected all data woud be still in place, but nothing could be found. The webinterface (ZFS info) just gives an error.
Did we get something wrong with a ZFS mirror? Could´nt we run each drive independently in case of failure.
Thx for your response,
mhari
