10.7 Server - Remove RAID 0 ?

Hi, I recently upgraded my Mac Mini SL server to Lion server ... after having some troubles I reinstalled it.
I configured the drives (2x500GB) to be in a raid array (mirror).
Is it possible to remove the raid easily?
i was thinking of:
- Superduper the entire disk to an external device
- Remove the raid config leaving 2 separate disks
- Restore the superduper image to the first disk;
- (use the second one as a TM-backup).
I not quite happy with Lion as it is extremely slow. Opening safari or any othe application causes the system to not respond for a few seconds, even minutes. Could the raid config be a cause of these hickups?
Kind regards

Is the OS installed on the RAID drive? It seems really strange that everything would be so slow... are you sure both drives are healthy? Have you run Techtool Pro or some other disk utility on them?
As far as cloning the drive, your plan should work. I use CCC to clone my boot volume nightly, and can boot back and forth as needed. But if the drives are running poorly (the drives in the Mac Mini are like 5200 RPM laptop drives), it might take forever to clone.

Mac Mini Server with Raid 1

Hi,
Is it possible to set up a Mac Mini Server with Raid 1 using only another mac computer such as a mac book?

Yes- Colin Jeukens posted step by step instructions back a couple of months ago. Here it is again...
Out of the box the mini comes without Raid. You have two identical HDs of 500Gb.
I have just set it up as Raid1. You can't do this when you use the startup disk from the mini. And as you don't have a Superdrive ... you need to be creative. You need another Mac with Firewire.
Step 1: Start the Mini in Target Mode. Press the T during start. In a few seconds the firewire logo will appear on your screen.
Step 2: Go to your second Mac. Connect the firewire cable between second Mac and Mini.
Step 3: On the second Mac start the disc utility. The two identical drives on your mini will show. Create a new Raid set (mirrored = Raid 1). Include both drives. Confirm the warning that all data on the mini will be lost.
Step 4: Make sure your second Mac has CD/ DVD sharing option installed. This is tou use the superdrive to install OS X Server on the mini.
Step 5: Shutdown both Macs
Step 6: Start your second Mac in target mode. Make sure the firewire cable is still connected.
Step 7: Start the Mini with the option key pressed.
Step 8: Insert the OS X Server install disc in your second Mac.
Step 9: wait till the drive logo apears om the Mini. Continue the install. Will take about an hour.

Mac Mini Server and RAID

Hello,
I have now the new mac Mini Server with LION.
All is already intalled but I would like to have a raid solution.
I looked here > https://discussions.apple.com/message/10819777#10819777
But it's Old and close, and there is no DVD in the Box.
I Know, I can download Lion & every softwares but I am not sure about the best way to do that.
First, I use a Big USB Key to use with Time Machine. Perhaps it will be better and fast to install than Apps with my internet connection. 2 - I have to use the disk application to format the 2 disks... Do I need to be in target mode with another mac ?
I read there is a problem after with time machine.. true ?
I am sure lot's of people want to use mac mini server with Raid disk.
Thank you for your help.

AppleIDAuthAgent[245]: SERVER Removing certificate for Apple ID

After installing Mountain Lion I can no longer use my Apple ID in the OS, except in iTunes. Whenever I try loggin into Messages, App Store or iCloud I get errors about not being able to communicate with the server. The ID works fine for logging in here as well as the web version of iCloud, and it works on my iphone too. My console is filled with these messages, appearing every ~5 seconds...
"8/3/12 4:09:09.720 PM AppleIDAuthAgent[245]: SERVER Removing certificate for Apple ID "ba...ow@?????.???" dsID="736e6f6c4d686b64435230342f44334b6a53454747513d3d" because it has expired or been revoked. (renewCertificateForAccount()/AppleIDAuthd.cpp #143) accountCheckDispatch"
I think the problem stems from this, but I'm not really sure what to do about it. Any help?

How did you fix it?

Removing RAID card from MacPro (2006)

I have a Mac Pro 1,1 (2006) which had been used as a server. It has an Apple RAID card installed (the first version, blue one, part number A1247).
I am now using this computer at home. The RAID card has failed. I'd like to remove it, reformat the drives and use the computer as a non-RAID version.
I have physically removed and unplugged the RAID card from the connector. I reinstalled the hard drives. However, when I boot up off the Snow Leopard Install DVD, Disk Utility cannot find the four hard drives that had previously been plugged into the RAID Card.
Am I missing a step somewhere? Is there more hardware beyond just the RAID card itself I needed to remove, and if so, can someone point me to the instructions on how to do it?
Thanks!
Matt

Just to elabroate on The hatter's post and in case anyone else stumbles upon this thread when searching about removing the Apple RAID card from the Mac Pro (pre-2009), the answer is within the first link in The hatter's post, namely this Apple user guide on installing the RAID card: http://manuals.info.apple.com/en/MacPro_RAIDCard_Installation.pdf
Basically, there's an iPass cable that connects the hard drives to the motherboard - but when you have your Mac configured with an Apple RAID card the iPass cable is connected to the RAID card instead of the motherboard. So when you remove the RAID card you need to connect the iPass cable back to your motherboard and that involves removing the fans, which is a tad fiddly. Make sure you've got a good magnetic screwdriver that doesn't chew screws!
Hope this helps someone out there
I've finally managed to replace my RAID card and dual SAS drives with a Vertex 2 SSD and I'm loving the speed, quietness and most importantly the fact I can now put my Mac Pro to sleep!!

Setting up the Mac Mini (non server) with RAID 1

I have a regular Mac Mini (Mid 2011) with Lion OS. I would like to change the hard disk to 2 1TB drives and use RAID1 to add some reliability to my data. Is this possible in the non-server Mac mini? Do I need to remove all my data to convert the system to RAID1 (assuming I can)?

Windows 7 on mac mini server and raid 1

I just purchased a 2011 mac mini server with the hopes of installing windows 7 alongside lion. Then my goal was to have the two drives mirrored. I successfully mirrored the two drives using disk utility and then proceeded to install lion. This all went fine. Imagine my shock when I loaded up bootcamp to see an error message describing it's inability to install windows on a raided system. The thought hadn't even occured to me that this would be an issue.
I have searched through various forums and other places on the internet and haven't found a solution. I am curious if I can get anyone with any experience in this area. Is it possible to have mac and windows installed on a drive... and have that drive mirrored to the second drive... regardless of what os i'm booted into?
Thanks for your help guys

The GUI version of Disk Utility is very limited in what sort of RAID configurations you can create. It will only allow you to have a single partition on the disk and to make a RAID using that.
Boot Camp requires creating additional partitions on the disk and hence it complaining.
There is a commandline version of Disk Utility called diskutility (duh!). It has far more options available. Details for this command can be obtained by typing man diskutility in Terminal.app.
It appears that in theory you might be able to do the following.
Start off with both disks not setup for RAID
Use Boot Camp to create the Windows partition. Repeat this on each disk.
Then in Terminal.app manually convert the boot Mac partition to a RAID using diskutil appleraid enable
Then add the matching partition on the second drive to make it a working mirror using diskutil appleraid add
Then in Terminal.app manually create a RAID for the Windows partition using both drives and use FAT32 as the format using diskutil appleraid create
Then boot and run the Windows installer and tell it to erase the Windows partition as NTFS
I cannot gurantee the above will work and you should obviously have backups if needed. Another option would be to have the Mac partition covered by RAID but not the Windows partition, this would result in three volumes one Mac RAIDed volume, and two other non RAIDed volumes even though you have two physical disks.

Remove RAID in S10 system

I have an S10 Thinkstation purchased 1/09 with a two-drive SATA RAID 1 array. It came with WIN7 but I ordered it with no OS and installed WINXP myself. I remember it was quite difficult.
Now I need to upgrade to WIN7. In the process I would like to remove the (now degraded) RAID array and install WIN7 on a (new) formatted spare hard drive that I ordered with the system. I will use the two existing RAID drives as backup drives within the case (I use MOZY for backup as well). There is also a third, older hard drive, from my previous workstation, installed as a backup drive. I also have a smaller external hard drive with two swsppable drives.
It's been a long time since I fussed around under the hood and I don't recall if the RAID was set up in the BIOS or just configured during the install.
Can anyone help an old retired woman with a How-to-Uninstall RAID walk-through? I'd like to preserve all the drives I can.
Solved!
Go to Solution.

This part of your question is probably better suited for the Microsoft forums as the details about licensing can get kind of tricky. As far as I know, those "system builder" installation discs are just that...for use by system builders. I believe that the major difference between those versions and retail versions is that there is no path for upgrading and existing OS...only a clean full intstall of the new OS. If your intent is to do a clean installation, you are essentially the system builder andI think you might be OK.
But as I mentioned, it's probably better to check with the MSFT forums to be sure before proceeding as you'll likely not be able to return anything after it's been opened.
Also, keep in mind using a 32-bit OS puts a pretty massive limitation on the amount of memory you'll be able to use in your system. 32-bit operating systems can't address more than 4GB of memory. Of that, probably less than 3GB will actually be usable (avaries based on configuration and BIOS settings). 64-bit is really the way to go if you can swing it. Just some food for thought.

Mac Mini Server HDD raid failure help

My server has been running for years, perfectly, most of the time. It is set up as a mirrored raid set.
I noted today that the second HDD is displaying a "failed" red flag in disk utility. I attempted to Rebuild and that failed.
In the FIRsT aid tab Verify returns errors. "This disk needs to be repaired using the Recovery HD..restart control r....etc."
There's my problem. No monitor or keyboard. I'm using screen sharing from an imac.
Is there a way to run the server reboot remotely?
Is it time to purchase a new server or simply replace the faulty drive?
Cheers
Gaz

Hi Chaz,
Is it time to purchase a new server or simply replace the faulty drive?
I think replace the faulty drive is thw answer.

24/7 laptop server remove battery?

I just acquired an old PowerBook G4, which I plan to install and run as a 24/7 media server which will stay plugged in permanently and never be physically touched.
Should I remove the battery permanently?
I'm just wondering if the battery is a fire hazard, or whether it would get damaged by remaining plugged in 24/7 and never actually being used to hold a charge, etc. Or that it would use more energy.

Conventional wisdom is that the battery acts to smooth out the power supplied by the AC adapter, and is an important component for reliable operation of the computer. It can be removed for debugging, but should not be removed from a computer in constant use.
If you wish to lengthen battery life and maintain the battery in working order, the recommendation is to discharge/recharge it about once a month.
Be sure that the screen is blanked when possible, as leaving it on full time will make it become permanently and irreparably dim.

Exchange server-Removing a Domain Controller from the forest

Hi Guys,
I need some help on removing a faulty domain controller from the AD forest. Here is the scenario:
1. The FSMO roles have been seized to a new domain controller already.
2. The old one is non-functional and is down for ever.
I know the steps would be doing a meta-data cleanup And then remove some of the DNS entries related to the old server. But the real issue is:
> I have Exchange 2013 running in one of the machines configured in the Forest, which was migrated from the old Domain controller. I then set Exchange listening to the new domain controller.
So, my doubt is, if I delete the old domain controller and do a metadata cleanup, would it have any effect on the exchange server? The Exchange machine acts as an additional domain controller as well. Its a production environment and any
change that affects Exchange would cause a big loss. Looking forward for your valuable suggestions..
Regards,
Nash

Hi Ed,
I don't have issues with the AD on the Exchange server. Eventhough it is configured as an AD, Exchange is pointed to the main working domain controller, which is a different machine. I just want to remove the traces of an old domain controller from which
I transferred the FSMO roles to the new domain controller. The old domain controller is completely down and hence I can't do a conventional 'dcpromo' on it. So just planning to do a 'metadata clean up' for removing the non-working DC from the forest.
So, In essence, I just want to know that, if I do a metadata cleanup, would it affect the Exchange server in any way?
Regards,
Nash

Win 2003 server SATA2 RAID 0 install errors

I keep getting the following error when trying to install Win 2003 server, as it is loading drivers:
"The file iaStor.sys is corrupted.
Press any key to continue."
Note: I get this error on every copy of win2003 server that I have AND I get it when trying to F6 install Intel's SATA RAID drivers from floppy, so it isn't really a corrupt file.
So I continue on and finally when trying to load windows it says something about windows not detecting any harddrives. Well, bios sees them fine. The ROM Intel Matrix Storage Manager sees them fine. I have all 3 drives set on one volume in Intel Matrix Storage Manager for a total of 698.7GB's. If I change to SATA Mode IDE the BIOS sees them fine.
I have the following relevant BIOS settings:
SATA Mode RAID (I've tried all 3 settings with no luck)
SATA Post speed setting DISABLED (I've tried Force Gen2 to no avail, and yes the HD jumpers are off so it runs at a full 3gbs)
JMB361 Disabled (I don't have anything on SATA port 5)
I've messed around with practically every possible combination of settings and am at a complete loss here as to what I should do to get this thing working. I've even tried skipping RAID completely. I've read through the (confusing) mobo instructions multiple times and just don't see what I am missing here. =/ Any help would be greatly appreciated! TY! See profile for hardware specs.

Well, you can only find out by re-installing the system with SBE 2003 again and if it doesn't works, you've got to install SBS 2003 back...
It depends on how you want to play the game. A shot that may help you or burden you .

LDAP server removed from tree still being referenced.

Greetings,
NW6.5sp8
It seems a server I have removed from my tree is still being referenced.
On my Apache console screen im seeing it referencing 172.16.10.1. Which, again, has been removed.
ldap *MASTER[172.16.10.1] down
LDAP initialization failed. Check LDAP and restart apache.
That's what im getting. I ran a PKIDiag 4-0. That didn't fix me.
If someone could point me in the right direction to resolving this issue, I would certainly appreciate it.

DFS server removal

Hello,
I have a domain controller that I would like to decomission and remove. It is also one of three namespace servers. How can I remove it as a namespace server? It actually isn't sharing any files in the namspace on the server.
Thanks,

Do it in the DFS console. On the left click on the namespace that this DC is a namespace for. On the right click on the Namespace Servers tab. Highlight the DC and click on Delete to the right of that.
