Hello list, I plan on rebuilding my home fileserver next month with FreeBSD 8.0 x64 and will be using 4x 2TB drives in an external eSATA hotswap enclosure using RAIDZ. I have played around with FreeBSD in VirtualBox just to see how easy it is to deal with ZFS, but a few questions have come up for this configuration. 1) In the event of a disk failure, how do I trace back the name such as adX to a physical drive in the enclosure? Is there a way to take the drive offline then use atacontrol to spin it down or something so it is easy to identify? 2) In the event that I do experience a failure and manage to replace a working disk instead of the failed disk, am I now completely hosed or can I put the working disk back in and try pulling another drive which is hopefully the bad drive? 3) Finally, does the extra load of resilvering the replaced drive 'age' the good drives causing them to fail quicker? Any tips would be greatly appreciated. Thanks.
