Can I set up RAID 1 in Mac Mini Server?

Sorry if I am in the wrong forum, but would like to know if the new Mac Mini server can be set up as RAID 1 or 0 and does it require reinstalling OS after formatting, or it comes already in RAID?
thanks,

Officially, yes, you need to off-load to a backup, configure the RAID-1, and reload onto the mirrorset.
If you're feeling lucky, you can potentially [activate RAID-1 without the archive|http://www.afp548.com/article.php?story=20040827122302975]; on-line. Search for (other) discussions of using the DiskUtil tool and enabling disk mirroring for various of the previous discussions.
But if something goes wrong with the on-line conversion, a bug or a power drop-out or a disk glitch or or... ?
RAID-0 is striping; two disks together presented as one bigger disk; targets I/O performance.
RAID-1 is mirroring; two disks together presented as one; targets reliability.
RAID-0 and RAID-1 (and the other RAID levels) can be hardware-based or software based.
The Mac Mini Server uses software-based RAID.
And for completeness, neither RAID-0 nor RAID-1 is an archival strategy.
As for the other question, do you have one disk showing, or two? If two, you're not running RAID-1. All of the Mac Mini Server boxes I've seen have arrived not configured for RAID-1. They've arrived as two single disks; as what the RAID folks tend to call JBOD; Just a Bunch Of Disks.

    You should find a card (size like a cd jacket) with serial no. It should be put all together with an installation DVD and user manual etc.

  • RAID on Mac mini Server (2011 i7)

    I just purchased a new Mac mini Server today (the base configuration 2011 Quad Core i7 with 4GB RAM and 2x 500GB 7200RPM magnetic hard disks) and wanted to share what I've learned about setting up RAID on the system.
    First, as you may have heard, the Mac mini Server does not include any installation/reinstallation media (I was hoping for a USB reinstall key, but it seems that the new systems don't include these or optical discs; last year's Mac mini Server included handy reinstall DVDs even though the system didn't have an optical drive).  Out of the box, the new Mac mini Server has Mac OS X Lion, the iLife suite, and the Mac OS X Lion Server tools pre-installed on one of the two 500GB internal drives; the other disk is formatted as a separate, second drive.
    If this is the configuration you're looking for, you're good to go right out of the box.  As an aside, this shipping configuration is ideal for using the second disk as a Time Machine drive.  I would argue that Time Machine would be a better use of the second volume than a RAID 1 configuration, as Time Machine provides versioned backups and you don't incur the write performance penalty RAID 1 requires every time data is saved to the disk.  I would further caution that, while an internal Time Machine disk is a convenient safety measure, any critical data should be backed up outside of the system as well.
    Now for those like me who were intrigued by the opportunity to mate the Quad Core i7 with a RAID 0/striped configuration for a performance boost (or if you want to use RAID 1), a RAID configuration is possible, but it there are a few caveats.
    First, Apple has two recovery options for the new Macs: a small hidden recovery partition on the boot drive and their Internet Recovery system.  While it's possible to boot other systems from a Lion installation DVD extracted from the App Store Lion installer, such bootable optical discs will not boot the Mac mini Server at this time (this may change if Apple modifies the App Store Lion installer).  Therefore, as of right now, the recovery partition or the Internet Recovery system are the best options for installing/reinstalling on a RAID set.
    Second, if you boot the system using Command+R to access the recovery partition, you can wipe the two drives and create a RAID set, but this process will remove the recovery partition and is incompatible with FileVault encryption (a warning to this effect comes up when you try to start an install/reinstalll on a RAID set, but at that point, you've likely already erased the recovery partition in Disk Utility).  If the system boots after the recovery partition is deleted, the only install/reinstall option is Apple's Internet Recovery.
    Third, as might be expected depending upon your internet bandwidth, the Internet Recovery system can take a while to boot the recovery tools (10-15 minutes to boot on a standard cable modem connection) and to reinstall the OS (50+ minutes on a standard cable modem connection).  Internet Recovery currently reinstalls only Mac OS X Lion and the Server tools on the mini Server; there's no option to install iLife during the OS install (Apple could always change this by updating their servers, and there is a Customize button on the installer, but it is greyed out and cannot be clicked at the present).
    Fourth, once the OS is reinstalled, it's possible to reinstall the iLife applications by launching the App Store from within Mac OS and selecting Purchased.  The store will indicate that the system is eligible to download the iLife apps and you can do so by agreeing to upload system-identifying information to Apple and signing in with your Apple ID.
    I hope all this helps.  Here's a more concise step-by-step of how to set up the system with RAID:
    THINGS YOU NEED
    A fast Internet connection for the mini
    Patience
    Hold Command+R on the keyboard at start up to boot from the system's recovery partition (if the recovery partition has been deleted, the system should start from Apple's Internet Recovery system; you may need to connect to WiFi if wired ethernet isn't available)
    Once you get into the recovery utility, select Disk Utility and for each of the two hard drives:
    highlight the drive
    select the Partition tab
    select 1 Partition from the Partition Layout pulldown menu
    select Free Space from the Format pulldown menu
    click Apply
    After you've wiped both of the drives, highlight one of the disks and click the RAID tab, then create a RAID set (striped or mirrored, as you prefer)
    Quit Disk Utility and from the main recovery utility menu select Reinstall Lion (from this point on, if you have any trouble, you can restart the mini from the Internet Recovery system and return to this point, but the recovery partition will be gone as long as you keep the RAID set)
    After you install and configure Mac OS X Lion Server (which can take well over an hour to download and install), you should be able to reinstall the iLife applications by launching the App Store App and selecting Purchased, then logging in with your Apple ID and agreeing to send your system info to Apple to download the iLife Applications
    If you're using the mini as a production server, I highly suggest setting up some local, external recovery tool, as you don't want to have system downtime protracted by having to wait for an Internet Recovery boot/reinstall.  I would also beg Apple to consider this sort of scenario and to provide more supported methods for recovering and reinstalling from local media.
    Best of luck to you all.

    I found the basic principle on another forum thanks to a guy called 'e-whizz' and this what I did to make RAID 1 work on a mac mini server with LION server.
    You can easily configure the second drive on a mac mini server for a Mirrored RAID 1 set with Lion Server without either reinstalling or erasing your existing setup.
    The initial setup process takes about 30 minutes, though the rebuilding of the mirror disk will take several hours, depending on the amount of data you have on the drive. It took around 3 hours on a new mac mini server with lion server installed, nothing else configured.
    Before you start, please ensure you have a current backup of the server. Getting the following commands wrong can render you server unusable.
    What you need to use is the command line version of Disk Utility, diskutil.
    Before you start, clone the hard drive. You can use SuperDuper (or similar, I have used SuperDuper) with copying all files onto a USB memory stick. If Lion is freshly installed, 8Gb will do. SuperDuper will create a bootable copy on the USB.
    Boot the mac mini from the external USB. To do that, reboot and hold down the option key while restarting. You will see a window, select the USB drive to boot from.
    Launch the terminal and type the following command:
    diskutil list
    This gives you a list of all the drives and partitions your system knows about.
    You need to find the Server HD partition (the first disk) and the HD2 partitions (the second disk). These are the two main ~500GB drives. You will be using the disk IDENTIFIERs when issuing the diskutil commands. For a stock standard Mac Mini Server, the commands below are correct, but if you have previously changed the volume names, or repartitioned at any stage the disk identifiers and volume names may differ.
    First enable RAID mirroring on existing Server HD volume. This will create a single disk, unpaired mirror, without affecting your data.
    Using this syntax:
    diskutil appleRAID enable mirror disktomirror
    where disktomirror is your disk identifier for Server HD
    On my mac mini server, Server HD was disk0s2, so I used this command:
    diskutil appleRAID enable mirror disk0s2
    You now need to run diskutil list again to see the disk identifier for the new RAID volume. The new RAID volume will be listed as disk# on its own at the bottom of the list.
    On my mac mini server this was disk3 (disk 2 was the USB I booted from, disk 0 the first disk and disk 1 the second disk)
    Next add the disk HD2 to the Server HD raid mirror volume (on my mac, as I said before, this is disk3) as a new member.
    This step will erase disk HD2 and begin an auto repair of the Server HD.
    Using this syntax:
    diskutil appleRAID add member newdisk raidvolume
    replacing newdisk and raidvolume with your particular disk identifiers
    On my server this was:
    diskutil appleRAID add member disk1s2 disk3
    To follow the progress of rebuilding the mirror set, type
    diskutil list
    It will show you the progress in % of the rebuilding under status
    Once finished, reboot and your RAID 1 is up and running and you have also a working backup on your USB (coz' that's where you booted from ;-)
    After reboot you can check the status of your RAID with
    diskutil appleRAID list
    Both drives should show ONLINE under status, interestingly, the device node for the RAID changed on my mac mini server from disk3 to disk2
    That's it

  • Please help. Can no longer connect to my Mac Mini Server

    Up until two days ago, my iMacs were connecting to my Mac Mini Server normally. All of a sudden I could no longer transfer files without being prompted to type my password.

  • Can't log new user onto Mac Mini Server

    I can't log a new user into Mac Mini server.  Have added the user to the Workgroup Manager, and am now trying to use the password created there for log-in on user computer. Any advice?

    Do you have Server Access Control Lists (SACLs) configured?  If so, you will need to add this new user to the appropriate SACLs before it can connect.  As an example, when I create new users, I need to add them to the File Sharing SACL or they never see any available shares on the server.

  • Can I install Snow Leopard on Mac Mini Server hardware?

    What I would like to do is buy the Mac Mini Server but I don't need the server OS. I want the desktop OS on the Mac Mini Server. Will installing Snow Leopard on the server hardware be just like installing it on a regular Mac Mini?
    Or should I just wait and see how Lion shakes out?

    Thanks Indy, I already had proceeded the installation according your tip. Just an objection related to the updates: I was able to install the OS updates only while in target mode, as when I made 2 attempts to update the version 10.6.6 to the current one (10.6.7 - the combo one and the MBP version too) it was not permitted. I had to plug the FW cable into the MBP again and update the Mini's OS (using the special MBP version of 10.6.7) in target disc mode. I want to use the Mini as a media server and intend to install Windows 7 on the other HD which now hosts the server OS. However, according to one poster (Sven G) there are some problems (I don't know exactly what they are) related to Boot Camp software. Have you any information about these problems?
    I have maintained both OS (standard and server) living side by side on the Mini, is there any problem with that?
    Again many thanks, you were succinct, right to the point, and your tip just proved itself correct. 
    Cheers

  • Can't connect to Mac Mini Server

    I am setting up a new Mac Mini Server for the first time and cannot connect to it from the local network. The Mini is connected to the local network and the internet via an Airport Extreme Base Station. The server appears in the Finder of my MacBook Pro under "Shared" but will not connect. I was able to connect prior to turning on some services in Server Admin (including enabling the Firewall). I allowed the server to control the Base Station upon initial setup but was not sure if it configures and turns on it's firewall services automatically. Should I have Firewall enabled in Server Admin?

    Blankfer,
    Did you re-enable Firewall in Server Admin and then open the screen sharing ports?
    I'm still confused as to whether the Firewall in Sever Admin is only supposed to be used when the sever is acting as an internet gateway. I was under the impression that the Mini was controlling my Airport Extreme's firewall services for me in the background. After my initial configuration through Setup Assistant (including selecting the option to have the server control my Airport) the Firewall in Server Admin was not enabled. Does Firewall being disabled in Sever Admin mean I have no firewall up at all? ...I plan to have it running web and mail services so I need to make sure it's secure.
    -Thanks

  • Mac Mini Server with Snow Leopard - PARTITIONS

    I may be mad but was wondering - why does the mac mini server create a partitioned HDD? I want to use the 1TB with out a partition - am I right in thinking that to solve this I simply delete one of the partitions (obviously the one that is empty)? I need to use the whole HDD and intend to back it up using a Time Capsule. Can anyone advise?
    Many thanks

    The mac mini server comes with 2 physical 500Gig drives. It's not one drive that's been partitioned so you can't delete it to get 1 TB. What you can do is define a Raid 0 set in disk utility so that the 2 physical drives look like 1 logical 1TB drive.
    Here's a little overview of Raid:

  • Mac mini server won't load after creating RAID0

  • What is "best practice" to set up and configure a Mac Mini server with dual 1 TB drives, using RAID 1?

    I have been handed a new, out of the box, Mac Mini server.  Has two 1 TB drives in it.  Contractor suggested RAID 1 for the set up.  I have done some research
    and found out that in creating the software RAID, this takes away the recovery partition, so I have been reading up on how to create a recovery "disk" using a thumb drive.  this part of the operation I am comfortable with, but there are other issues/concerns that I have.
    Basically, what is the "best practice" to setup the Mini, configure the RAID and then start the server.  I am assuming the steps would be something like this:
    1) start up the Mini and run through the normal Maverick setup/config - keep it plain and vanilla
    2) grab a copy of the Server app and store it offline in a safe place
    3) perform the RAID configuration / reinstall of OS X Maverick using the recovery tools
    4) copy down and start the server app
    This might be considered a very simplified version of this article (http://support.apple.com/kb/HT4886 - Mac mini server (Late 2012 and Mid 2011): How to install OS X Server on a software RAID volume), with the biggest difference being I grab a copy of the Server App off of the mini before I reinstall, since I did not purchase it from the App store, but rather it came with the mini.
    Is there a best practice /  how-to tutorial somewhere that I can follow/learn from? Am I on the right track or headed for a train wreck?
    thanks in advance

    I think this article will answer your question. Hope this helps: http://wisebyte.blogspot.com/2014/01/best-configuration-for-mac-mini-server.html

    You will need to enable file sharing in System Preferences
    as well as setting up sharing and permissions for the
    directories that you want shared.  You may also want to
    setup a non-administrative user or allow limited guest
    access.  The user would require entering a user name and
    password to make the connection, but would allow remotes
    to change files, if set up tat way.
    As for serving iTunes media, better to post in the iTunes forum.

  • How can I create RAID 1 on Mac mini server just now from box.

    I bought my Mac mini server two days ago and decided that 1Tb + 1Tb HDD are very good for RAID 1 (mirroring).
    Thinking - doing ... Open Disk Utility, try to change and create RAID. Nothing. Try to reinstall OS X - recovery part are on disk all time.
    Does anybody can help me to create what I want and how to do this with minimum energy. Thanks a lot.

    Start from an Internet Recovery which boots you into it's own Recovery Partition. From there use Disk Utility to put your 2 drives into RAID 1. Reinstall OS X from the Internet Recovery once you have done that and install everything else as you need to.
    Be aware that RAID volumes do not have their own Recovery Partition so you will need to either have an external drive with an RP to boot into else you will need to use Internet Recovery each time (which is around a 650MB download).
