Looking for opinions on Apple's software RAID in Disk Utility

I'm thinking about making a stripped RAID (RAID 0) with Apple's software RAID in Disk Utility. How reliable is it, and will I see a huge speed improvement over just having two independent drives. This RAID will also be my boot drive. Is that a good idea or should I have a separate drive for that function?

It depends. And seeing you don't have a lot of exposure to RAID, it depends, you still need even more to regularly backup, and depends on the drives to some extent. RAIDs are great for some things, and the sustained reads and writes look good in some simple benchmarks, but for most users, they are better off with a really good fast 10K Raptor or something as a dedicated OS/apps boot drive.

They did some earlier tests on RAID for boot drive, which you might want to look into.

Software Update and Disk Utility no longer work (Leopard)

Hello. After upgrading yesterday from 10.4.11 to 10.5.0 then updating to 10.5.1 I find that repair / verify permissions no longer works (it just hangs after starting).
And the same with Software Update, it starts the check then just hangs. Grateful for any ideas!
Overall I am finding Leopard much slower in operation than Tiger. Peter

Create a new admin account with Apple menu -> System Preferences -> Accounts and see if the issue duplicates itself logging into that account. That will say if the issue systemwide, or just localized to the a bad user cache file. If the issue persists in the new user, you can try looking in the System -> Library and Library -> Cache, Applications Support, and ByHost folders for cache files relating to Software Update and Disk Utility. Once you find them, carefully extract them to comparable folders on your desktop you create (i.e. name one systemlibrarycache) so you know where you go them from, and restart your Mac. If the issues go away after two restarts then it is just one set of bad cache files. If the issues return after two restarts, you have something generating bad cache files which needs a more system wide repair tool.

Problems running Software Update and Disk Utility

I had automatic updating turned on in the Software Updates control panel, so I believe the system tried to apply the 10.4.6 automatically and somehow failed.
Ever since, when I try to run Software Update it hangs while trying to connect to the internet to get the list of available updates. I tried downloading the installer directly from Apple, but when I try to select a volume on which to install the update, it doesn't list my hard drive.
Finally, when trying to run the Disk Utility, I get an error about how the Disk Utility cannot be started because a background process is not running. I have to Force Quit to exit out of the Utility.
I was able to boot off the Mac OS X 10.4 installation DVD at which point I repaired the permissions and repaired the disk. However, upon restart the same problems remain.
I've seen several other people post about this issue; has anyone found a resolution OTHER than doing an Archive and Install (which I don't want to do if I don't have to?)
Thanks so much for help that anyone can provide!

Looking for Solaris 9 9/05 Software Supplement CD

Is there a Software Supplement CD for Solaris 9 9/05 (SPARC)? There was one for Solaris 9 9/04 but I can't find one for 9/05. I am referring the the Software Supplement CD (including VTS, RSC, ALOM, etc.), and not the Software Companion CD.
Thanks

If you are looking for a recent Solaris 9 Software Supplement CD, these aren't available for download. You have to order/buy the Media Kit.
Sometime there was an image available with earlier Solaris 9 versions.

Xserve RAID won't RAID in disk utility

I have a XServe RAID that won't RAID in disk utility. The XServe is fully populated and there are two arrays created. Both of those arrays show up in disk utility and will only be partitioned with an Apple Partition Map. If I try to partition them GUID, that partition fails (system formatter failed). Once, I partition them APM, two volumes show up on the desktop. Then, I try to create a software RAID with those two volumes and I can not get the volumes to RAID together. The error message in disk utility says (RAID can not be modified). I have checked the system log and it says something about a socket error or that it can not bind. Does anyone have any ideas on why I can not create this RAID?
My end goal is to have 2 hardware RAID 5's and put a striped RAID set on top of that to have one large volume for Final Cut video editing.
I'm using a Mac Pro with Atto Celerity 42ES fibre card.
Thanks

This may be a little too late, but maybe it will help. I'm not sure why this happens. I reinstalled my server, and I could not access the drives, even though they showed up in disk utility (as a blank file).
Here is what I did to fix it:
1. Open up Disk Utility
2. Make a disk image of the drive you want to mount, save this somewhere accessible (i saved it on another one of my RAID drives)
3. Erase the disk, it should then mount and be accessible
4. Restore the image onto the drive.
Cheers!

"Create" button dim when attempting to setup mirrored RAID in Disk Utility.

I'm trying to setup a mirrored RAID in Disk Utility (v10.5.6) in MacOS 10.4.11 on a PowerMac G5. I've got the System and all of my files on a 500 GB Seagate internal drive and I've added a blank 500 GB Western Digital internal drive to be the mirror. When I boot from the Seagate drive and run Disk Utility, I can follow all of the instructions for setting up a mirrored RAID (except the last instruction):
1) Launch disk utility.
2) Select my boot drive.
3) Click on the RAID tab.
4) Enter a RAID Set Name and select a Volume Format (Mac OS Extended Journaled).
5) Drag a drive or volume to the set. Okay, I actually have a problem here, because if I drag the boot volume or drive to the set, nothing happens (it doesn't appear in the selection box). So I drag the blank volume to the set and it shows up in the selection box.
6) Select RAID type (RAID Slice).
7) Click the "Create" button.
That's the step that I can't complete; the "Create" button is dimmed (grayed out, disabled). My boot drive isn't partitioned (it has just one volume), I've run Disk Utility to repair Disk Permissions before I attempted to set up the RAID, and both drives are formatted as "Mac OS Extended Journaled." The only potential cause I can think of is that the two drives I'm using, though they're both 500 GB drives, are from different manufacturers. I can't imagine that would make a difference though.
Why is the "Create" button dimmed?
Any help would be GREATLY appreciated!
Thanks,
Scott

Hi there,
Thanks for your help!
Your explanation makes sense. I've just recovered from a hard drive failure and although I'd backed up most of the files the night before, I still lost a day's worth of email and several days worth of other files. Mirroring appealed to me because then I'd always have a completely up-to-date copy of everything, but your bad experiences with it give me pause.
Is there another backup strategy you can recommend that would give me really up-to-date backups of my entire boot volume?
Thanks again!
Scott

Adding Drive to Concatenated RAID in Disk Utility

Hello,
I'm having a spot of trouble with Disk Utility. 24 hours ago I added a new drive to a Concatenated Raid through Disk Utility, and clicked Update to set the process going.
Now it's not responding. It just claims to be updating. I struggle to believe that it takes this long though!
I didn't format the disk before adding it to the RAID. Is this what's causing the upset?
When I try to cancel it tells me I risk losing data on the disk. I'm not sure if it means the new disk or all disks on the array - which is a terrifying prospect. If I quit Disk Utility, will my existing data on the array be safe?
Thanks in advance for the help,
Ben

The drives are in Sonnet P500 enclosures and connected to the MacPro via a Sonnet SATA card.
On purhcase I was told this could be done, as it's a Concatenated JBOD setup. For a better description of what I mean by that, this wiki article describes it well http://en.wikipedia.org/wiki/StandardRAIDlevels.
Does this provide any further clues?
Currently there are 7x 1TB drives in 2 enclosures. I've now added 2 more 1TB drives. I can currently see and continue to use the data on the existing 7 drives. My worry though is that if I quit the disk utility I may lose the data on the 7 original drives.

Erase and Install
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Quit DU after formatting completes and return to the installer. Install Snow Leopard.
5. After restart into Snow Leopard download and install Mac OS X 10.6.8 Update Combo v1.1.

Looking for opinions: AppleCare worth to pay for it ?

Within the next three weeks we have to decide whether or not investing around 1.000 Euro ($1.200 USD) into three year AppleCare support for our company's XServe.
At this time I had made only (more or less) bad experiences with the 90-days-support Apple provides (I can only talk about the German support, not sure regarding others):
Most questions became answered by refering me to knowledgebase articles not related in any way to my original issue. Also I heard often that this is a known problem, but cannot be supported since it requires command line access not under the support terms or that they will call me back (I had to call back each single time). One time I even got the advise to visit this forum
And during my last phone calls I also had the special pleasure to talk with a professional speaking some kind of "Gerglish" (German and English mixed). It was quite hard to get even an idea about what he is speaking, so after explaining my issue three times, I gave up. By the way, he also promised to send me knowledgebase articles - I never received them.
Only very few support calls were handled professionally. So I had a really hard time on getting anything set up, configured and worked around the bugs Apple ships with the servers. Many thanks to this forum, Apple should charge for using it and I would be the first paying for - hope that they don't read this and take it for serious The people here at this place are much more helpful as all German support representatives together.
But back to topic. I would like to hear some user experiences made with the three years extended support, especially from Germany-based people (hope that there are some users around). Good as well as bad ones.
So hopefully I get a better overview whether or not it is worth spending money or better diving into OS X Server by educating myself.

First, realize that the three-year maintenance agreement is only a hardware maintenance agreement. It is not for assisting you in setting up your server or working around Apple's bugs. Also realize that your experience in Germany may be different from my experience in the U.S.
That said, for us it has been worth it. We have had four incidents with our Xserve G5, and, in each case, I have been impressed with the telephone support we have received from the Enterprise Server Support Group in Austin, Texas. The first case was an apparent manufacturing error - rather than the 250 GB ADM drive that had been ordered, invoiced, and paid for, the server arrived with an 80 GB drive. Replacement drive overnighted, arrived next day. In the second case, our Apple Hardware RAID card had its firmware settings become corrupted in an odd manner where it still functioned perfectly as two RAID 5 LUNs, but the Xserve would not boot from it. This happened during replacement of the BTO Apple SCSI card (really a rebranded LSI Logic 22320) in the adjacent slot that never worked right with our backup software, replaced by an ATTO UL4D that has never had problems. Because no firmware file was available for re-flashing the card (even though I believed and still believe that the card itself was OK), a replacement Apple Hardware RAID card was overnighted, received next day, and solved the problem with the RAID card. The third instance was when the ribbon cable between the Apple Hardware RAID and the drives was suspected as being intermittent and, no questions asked, a replacement was sent. The fourth instance was when we got intermittent ECC errors. Austin support had us interchange two DIMMs to see whether it was the motherboard that they should send (if the errors did not follow the DIMM) or a replacement DIMM (which they should send if the errors followed the DIMM). Turned out to be the DIMM, and a replacement was sent.
I still have an open case on the Apple Hardware RAID card that has been open for over a year, now. The card has a bug in that it does not fully flush its write cache on graceful power down. Only workaround is to turn the write caches off, which is what we have done. Because the Xserve G5 (and its Apple Hardware RAID card) is EOL, I doubt that this bug will ever be fixed. But the hardware is broken (unless you think it is normal for a disk controller card not to flush its write cache on graceful power down before disconnecting from the drives).
My only complaint is with the local on-site subcontractor. There are not many Xserves in our city. When the Apple Hardware RAID card failed, we had to make numerous follow-ups to get the local service person to contact us following the initial incident report with Austin, even though the server would not boot from the Apple Hardware RAID (we kept the server up by booting to an external firewire drive). When the local on-site repair person finally contacted us, I was not impressed by his total lack of knowledge about the Xserve, and I do not believe that he had ever seen an Xserve, much less ever having been trained on the product. I told him that I did not want him touching our server, relayed that information to Apple's support group in Austin, and they just overnighted the replacement Apple Hardware RAID card to me for replacement by me.
So, if you are expecting setup assistance or assistance working around bugs in the software, you aren't going to get it. It's strictly hardware repair. If you are looking for bug reporting or workarounds, the best route there is to get an Apple Developer membership (they are free if you get the entry level that doesn't provide prerelease software) and to file bug reports via RADAR.
Hope this helps,
Russ

I realize iTunes is available for partial backups.
I do sync with iTunes. I don't like iTunes.
1. I have 4 different devices I need to backup up. iTunes lets you have one account sync'ed to one PC.
2. iTunes doesn't backup everything.
3. iTunes fails sometimes and you loose what you have sync'ed. I would like backup software that is more reliable.

I upgraded the validation extension last year only to find
many of the

issues. I have
dropped them a line a few times requiring info as to when
they might have
another release, but web assist dont seem to inform their

things until the day of release.

Looking for a free stop motion software for my Macbook Pro?

Sorry if this is in the wrong category; I am new here.
I'm currently working on a 40 minute stop motion film. I've experimented with various stop motion apps, but none of them fit what I need. I'm making the film in 9 parts, and I want to be able to export each video as a .mov file and later import into FCPX to make edits and combine everything. I have the audio completely recorded and I plan to take the pictures using my Macbook Pro's built-in webcam. (This film doesn't need to be very fancy; it's for my family.)
I'm looking for something free (not a free trial) and without a watermark. Each of the 9 parts is inbetween 3-8 minutes. What do you recommend?
Thanks

You can do it, but are you prepared to spend? it won't be cheap. It may be cheaper than I thought.
You will need a projector with an HDMI input, and you will need a method of transmitting the HDMI signal, complete with all ancillary protocols (so HDMI 1.2 at least, 1.4 is safer) via wireless. That means way more bandwidth than 2.4 or 5G wireless can offer.
I have had success with the TruLink 60Ghz WirelessHD transmitter/receiver, 30ft range (20 is more 'real world') 1 hdmi in and 1 hdmi out, so they replace the cable. Last pair I bought were $600, but I just saw that Amazon have them available at $141 ....
However these are line of sight devices, no motion and no obstruction between the pair or fuzzzzzz

Looking for Win-based sound-editing software to work with AAC files

Hi, everyone.
I'm a part-time indoor-cycling instructor. I create iTunes playlists to fit a certain types of "rides," transfer the lists to my iPod, then hook the player to the club's stereo system. Very slick.
But not slick enough. There are some songs I don't want to play all the way through; I want to use only isolated segments of certain songs. And I want to employ crossfade. When cycling, it's important to keep the music coming; dead spots are energy killers. I want to stich in some stray bits of oddball audio, such as funny snippets of movie dialog and other nonsense, to keep the mood light. And I'm looking for a way to more precisely control track-to-track playback volume.
I know I can isolate a segment of a song file by using the "start time" and "stop time" adjustments on the "options" tab of a song file's "get info" settings within iTunes. But I want to do more than that. Sometimes I want to play :20 of a song at one part of the ride, and :40 of the same song later in the ride, and I don't want to have to make a renamed copy of the song file to make it happen.
I'm thinking what I need is sound-editing software. I want to create, say, a 60-minute playlist in iTunes, export copies (not the originals) of the songs in that playlist to the sound-editing platform, do my editing and create a single, 60-minute file that I can then load into iTunes and thus, transfer to my iPod. When I hook the 'pod up to the club's stereo, I would then play the single 60-minute "song" instead of the 60-minute playlist.
And of course, I want to do it really cheaply, on a PC running iTunes for Windows. How's that for a challenge?
If I had a Mac, I probably could use SoundStudio to do this, because it imports AAC files.
What I need is a Windows-based editing platform that can import AAC files. If you know of such an animal, I'd appreciate hearing about it.
If there is no such animal, here's what I think I'll have to do:
1. Pluck song files from my iTunes music folder
2. Create a CD containing mp3 copies of those songs
3. Send those mp3 copies into the editing software
4. Stitch the songs together in the editing software into a single file
5. Export that file as a single mp3 file
6. Have iTunes convert that mp3 file to mp4.
Right? Or wrong? If anyone has advice, I'm all ears.

The reason why I posted here was to hopefully find someone who has actually done this before rather than have someone throw packages at me that I can find on Google on my own.
There are a number of SMS gateways out there, but I have not used any of them. Setting up some of them is a very time consuming process and I was hoping to get a heads up on one that that some else had used in the Solaris 10 x86 environment within a zone.
I already have a working email version of this process which I put together very quickly, but using SMS would be a much better process for the techs out in the field.
I won't have the actual GSM Modem in hand until Monday or Tuesday and am doing some preliminary work so that I can hit the ground running when it shows up.
Thanks for your suggestions though.
