Christian Zartl, November 22, 2011 This is the German translation of the original English FAQ from here on the forum: FAQ-Those-common-questions-that-keep-getting-Asked-and-Answered-about-FreeNAS-8 yang ming line (compiled by Users protosd). In general, the FAQ, however, should be maintained yang ming line so that it does not become too cluttered.
Please post any posts here! This topic will be closed to the sticky thread and is intended solely for the FAQ. For desired changes, suggestions, corrections or suggestions please drop me a PM. However, I offer no support, yang ming line I'm just doing the translation! Please, if you have an idea for a question included response / link, send a PM to me (German) and protosd (creator, English) and we will add it here. This FAQ does not come alone from protosd, many persons have given their answers to them, he has compiled only all the information here. Please, if you would like to help translate this FAQ, send a PM to protosd. 1) If my hardware / my motherboard is defective, can I restore the system with new / different hardware and still import / read data from the hard disks? How it looks with my dataset?
YES, as long as you do not use a hardware RAID and instead take care of the ZFS RAID. A dataset is basically a folder / directory that together with your other files on your disk, but under a different mount point such as / mnt/dein-pool/dataset_1, is located. yang ming line 2) Can I start with one or two hard drives and easily add more later?
YES, but only under certain conditions. You can simply nich disks mix, vote on each other and always add new like Openfiler or Drobo for example, unless you used only UFS formatted disks and waive properties such as mirroring (mirroring) or ZFS raidz. Here are some links from this forum, the more detail discuss the: add-additional-disk-to-volume Recovering-data Question-on-setting-up-drives-for-ZFS Here is a really valuable post about ZFS information on disk configurations etc. Getting-the-most-out-of-ZFS pools! 3) I have a faulty hard drive, how can I find the serial number to make sure that I remove the correct disk?
In the left menu bar of the graphical interface by clicking on Storage Systems -> Disk -> Show all the disks and then clicking on the icon with the little magnifying glass (more disks) next to the name of your disk. The serial number is listed next to each disk device name. You may have to run through the column expand to be able to read the complete serial number with the mouse. From the command line you can see the name of the device - about ADA1 or ADA2 example - display, which outputs FreeNAS as failed (failed) (replace below ADA1 by the found of you device name): smartctl-i / dev/ada1 4) How to exchange I have a defective drive?
Currently (version yang ming line 8.0, 8:01 betas) it is not safe or recommended to replace yang ming line a faulty hard drive via the graphical interface. First, you should run some commands at the command line and after you're done with that try to reveal the graphical interface, that a hard drive was getausche. The latter works better with the latest release 8:02 and it is strongly recommended that you first upgrade. Determine which disk needs to be replaced (in this example ada7 in a RAIDz1/z2 named tank) Identify the physical disk System Shutdown Remove ada7 and exchange it with a new hard drive (same size or larger) on the same line from Turn the power on ( tank will be located in a DEGRADED status and / dev/ada7 not be available) In the command line enter zpool replace tank ada7 a The pool will begin to restore itself. This can take a long time, wait until it is finished. You can status while with zpool status-v Check After it finishes, run again zpool status-v, it will still DEGRADED spend searching for the device name / dev/ada7/old Give the zpool detach tank / dev/ada7 / old one again Check the status DEGRADED yang ming line and / dev/ada7/old should disappear and the pool ONLINE state be Give the zpool export tank a hint: It was proposed to set up your new USB drive after shutdown. This is extremely and thus better yang ming line to first try the next step. If it does not work in the GUI under System -> Preferences -> General tab to Factory Restore button. Only if you still have problems after that, install the USB flash drive again and enter your settings n
