Non viable RAID set error

This is one of those problems that I don't know where to seek help from but here goes... I'm pretty much hosed anyway...
Since August 09 I have been running a RAID set consisting of 2 Western Dig RE4GP 2TB drive (resulting in a roughly 3.xTB volume). Everything has worked fine, every 6 months the Apple RAID card reconditions its battery... no problems... until last night at 10:55pm... I get this error message out of nowhere (I'm not doing anything special or taxing on the computer) saying that the RAID Utility app needs my attention. All of a sudden I see these 3 "severe" events that have occurred:
Wednesday, December 29, 2010 10:55:23 PM PT Non-viable RAID set RS1 and all associated volumes are offline critical
Wednesday, December 29, 2010 10:55:19 PM PT Drive 3:50014ee2583cccfd missing - Replace immediately or acknowledge loss of RAID set RS1 and associated volumes critical
Wednesday, December 29, 2010 10:55:19 PM PT Drive 3:50014ee2583cccfd missing - Previous drive status was inuse critical
After some panic and thought of what data I might have lost, I decided to reboot and of course the computer won't reboot (before August 09 I was having some nightmares with the Apple RAID card that came with the computer and after calling Apple and complaining, they sent me a new RAID that has been working fine since yesterday I guess). I forced power down and then removed both WD RE4GP trays (bays 1 & 3), restarted the computer and after a while, the computer booted up fine (boot drive is a WE RE3 in bay 1 and I also have a Seagate ES2 in bay 3). Both drives are "associated" in some operational way with the RAID card so this would indicate that the RAID card is working okay but could the WD RE4GPs have failed?? There was no mechanical noise or indication that the drive hardware had failed; after all these are "enterprise" class drives and only a year and a half old and they have never experienced any trauma. I have recently used Disk Warrior and all drives and the RAID set and everything passed without issue. So today I tried to re-insert both WD RE4 sleds into the computer but again it wouldn't boot up just like yesterday (just stuck at the grey screen, no Apple logo appears). Removing both sleds allows the computer to boot so at least some comfort.
Can anybody give me any tips to maybe save the data on the drives or what I should try? Thanks a lot!

At what point does this error occur? Can you provide more of the stack trace?

Non supported character set error

Hello, I have a j2ee application that uses OLAP API to make queries against cubes created with cwm2 packages, in a database (db 1).
I've replicated the schema in another db (db 2), importing the user (with a dmp file) and throwing the object creation scripts. This works right, and the objects in the catalog are all validated. But my j2ee application doesn't work against this new user; some errors appears.
The two databases are the same version, the only difference is that db 2 was installed using WE8ISO8859P15 character set. Is there any problem with this set and the olap api ? The character set in db 1 is WE8ISO8859P1.
The error is:
"oracle.express.idl.util.OlapiException: Non supported character set: oracle-character-set-46".
I'm using ojdbc14.zip and orai18n.zip in the WEB-INF/lib directory of my application. My database version is 10g r. 2 (10.2.0.1.0)
Thanks by your reply.

RAID Set not showing up - 3 severe events

Intelle Xserve running 10.6 RAID Card running firmware v E-1.3.2.0, Two it drives set up with I think RAID 5.
The main person for the system is away as well as his backup. So I'm running on very little information at the moment.
Log:
Called in due to user not able to access shared files (Also shared FileMakerpro databases and Portfolio server). Only access to server was via screen share.
Could not connect. After trying all that I could, powered down the server. Restarted, got a login startup permissions error for an item to run at startup. (I'll have to check what exactly that was). Started the Portfolia server and the FileMakerpro databases. Users able to access and use.
Next day same thing. User lost connection with the server. Restarted, start filemakerpro databases and portfoilio services. User able to access.
I suggest pulling over the files needed to work just in case it looses connection again, User starts to pull over some files which is transfering.
About 15 minutes later I get a call that the user lost connection again.
Restart the once again. This time get errors from the RAID utility:
Non-viable RAID set RS1 and all associated volumes are offline
Drive 3:500 missing - Replace immediately or acknowledge loss of RAID set RS1 and associated volumes
Drive 3:500 missing - Previous drive status was inuse
The RAID utility does not show a RAID set.
The drive appear to be OK
The drive shows up on the desktop but when I go into the drive the folders etc are showing. Access the main folder results in a loop where it bails out and just shows the desktop again.
I'm going to get some files to the user from the timemachine backup for now.
Is it possible that the data is OK and maybe the drive are marked off line for the set but still OK?
Any info would be great,
Thanks

Yes the 160GB has the OS. I'm coming into this cold as the main person and the backup are currently away.
I have got the users a work around so they can do thier work. The backup person has very limited email contact and he had thought it was a RAID 5.B But I would agree this looks to be a RAID 0 or 1 since there are only two drive available for data.

Apple RAID Utility Raid 0 one disk roaming making raid set not viable

Hello!
I have a problem with RAID 0. In the picture below you can see that one drive was set to missing and RAID set RS1 has been set to non viable. However all four drives(Bay1-4) are set to be verified with status good. However as can be seen from the picture Bay 3 is set to status: Roaming
I don't know what I can do here. There was some talk on other discussions but nothing that helped me
Thanks to anyone that read this and try to help me. If you need more detail I will be more than happy to give them to you.

An error with drive in bay 3 threw it out of the RAID, breaking the Striped RAID. You data will be very difficult to recover, since the data are striped on two different drives, and one of them is no longer part of that RAID set.
You now need to re-initialize the RAID set (which destroy what is left of the data) using the same or different drives, and restore the data from your backups if desired.
I recommend writing zeroes to every block on the troublesome drive before even thinking of returning it to service.

Error when mirroring two striped raid sets

I have an external 5 drive enclosure (sonnet fusion 500P) connected to my mac pro via serial host adapter (sonnet tempo SATA E4P).
While attempting to mirror two striped raid sets, or vice versa, I get a "disk utility internal error". I am able to stripe or mirror no problem, it is only when I try to mirror the two striped sets that the error appears and makes me restart disk utility.
Any ideas what is causing this error?

I had the same problem. I could not get the Disk Utility application to create a RAID 10 which is created by stripping two mirrors. I was able to figure out how to use diskutil to configure a RAID 10. Here are the steps that I used:
1. Open Terminal. Use the command "diskutil list".
2. Look for the name of the disk with a * next to it and make sure that the real disk name is listed in the "type name". Write down the "disk number" names of the volumes you want to work with.
3. Use the following diskutil command to create the mirrors.
"diskutil createRAID mirror RAID10 HFS+ disk4 disk6"
Replace disk4 disk6 with your disk numbers that you discovered in step 2 above. This command will create each mrror. Create two mirror sets.
4. As each mirror is created write down the disk number that is reported in this line: "Creating file system on RAID volume "disk5 "
5. Use the numbers of the mirror disks, as discovered in step 4 to create the stripe of the two mirrors. Use the command:
"diskutil createRAID stripe RAID10 HFS+ disk1 disk5"
Substitute disk1 disk5 in the line above with the disk numbers discovered in step 4 above.
Your RAID 10 is now completed.
Performance with this setup will be higher with a direct connect 4-bay enclosure like the FirmTek SeriTek/2eEN4 - http://firmtek.stores.yahoo.net/sata2een4.html
However, this should also work with a 5-bay PM enclosure just slower. Personally, I switched from the diskutil created RAID 10 to using the HighPoint RocketRAID 2314 for RAID 10 configurations.
http://www.amug.org/amug-web/html/amug/reviews/articles/highpoint/2314/
The reason is that while I can create a RAID 10 with diskutil it is complicated to build and complicated to rebuild when a failure occurs. The RocketRAID 2314 web manager makes all of this easy and rebuilds RAID 10 automatically. It just works while using diskutil sends you to the Apple Discussion Boards every time a problem occurs. This is one of the reasons I recommend the RocketRAID 2314 over the Tempo E4P SATA host adapter.
If I had a E4P and the 5-bay enclosure I would be happy with a 5 drive striped RAID set or purchase the RocketRAID 2314 so that I could easily support RAID 5 and 10 configurations.

Mirrored RAID set has degraded following power outage.

Hello,
Following a recent power outage our Mac Pro running Leopard OSX Server with 2 x 1TB discs in a Mirroring RAID configuration (with an installed RAID card) developed a 'severe error' message.
The Raid Set R0-1 has a Viable (degraded) status.
Drive One (or bay 1) is 'Good' and 'Assigned'
Drive Two is 'Good' but with the State - 'Roaming'
Also, the events display describes the failure of a drive 3 (there isn't one) and that the R0-1 is Degraded and no spare is available.
So, we're a little confused.
1. Is the Drive 2 no longer part of the RAID mirror (i.e. Roaming)
OR
2. Something more significant has happened hence the bogus Drive 3 message?
Any suggestions or advice would be much appreciated as always.
Thanks
Steve

Yes. Verification with the GUI tool is the first step. But... hmm, if you are dropping communications with the card, that is not a good sign. Make sure you have a backup and then try a PMU reset on the system. Maybe there is something wacky in the power manager. Then try any/all of these from Terminal to get more information:
raidutil list status
raidutil list eventinfo
raidutil list raidsetinfo
This should provide feedback. If these commands fail, then I fear that the card is not responding. Do you have AppleCare? It might be time to call for a replacement card.
Hope this helps

Updating RAID Set

I currently have a 1TB (2 500GB USB HDs) Concatenated RAID set. I've attempted to add a third 500GB hard drive to it, but after I click "Update" I get the error message "Unrecognized filesystem." I then check out the log and after the update process starts, the log records "Unable to find the member disk for this RAID set" and then the error "Unrecognized filesystem"
I've checked both the 2 HDs on the RAID and the one i wish to add. No corruption, and data can be written and read. I've searched through other discussions here and although there are similar reports, none (that i could find) mention the "Unable to find the member disk for this RAID set" log record.
Any suggestions?
10.5.2 and all software is up-to-date

First, prep the new drive properly:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X 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 Installer menu (Utilities menu for Tiger or Leopard.)
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. Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process will take 30 minutes to an hour or more depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.
Second, I'm not sure you can simply add a third drive without actually recreating the RAID which will erase all the data on the RAID.

Vista won't install on a RAID set. ***SOLVED***

I just installed my new MSI 790GX-G65 system and I cannot install Vista (32-bit) on any type of 2 disk RAID set that I have tried to create. I can get the installer to see the drive(s) by loading the driver, but after partitioning and formatting, I get a message about "windows cannot find a valid drive for install" or something to that effect. I can install fine using IDE mode and just picking one of the drives. Any help would be appreciated.

Quote from: FrogmanTM on 09-August-09, 05:39:36
Well, I solved it! The problem was with the Vista installation process itself. It turns out that Windows reads information about the boot sequence from the BIOS of the motherboard. It looks at this information to understand what will happen when the system boots for the first time. If you have a USB drive connected to the system and it is listed in the boot config as a bootable device (in my case the BIOS put the USB stick as the second boot device, right after the CD drive, and the RAID volume was listed AFTER the USB stick) - you will probably see this error: "Windows could not determine if this computer contains a valid system volume."
To get past it, I had to re-configure the BIOS Boot options to NOT include my USB drive as a bootable device (or just drop the priority below whatever drive you will be booting from). You can also boot your system without a USB drive installed - not an option for me since I need to install 3rd party raid drivers.
Whew! Thanx for all your help, I am glad I finally figured it out.
Wow dude you're a genius for two days I've been searching and searching and searching wondering why my vista wont install onto my raid 0. I have a DFI board with a 760fx chipset, i have done all the bios updates and brand new raid drivers and to no avail. Found this post and voila. Thanks a lot. Such a simple fix usually the last thing you think of or not think of it at all.

Mac Pro 2009 Raid Set Lost after Hard Reboot

We have a newer Nehalem based Mac Pro with a 2009 Black Apple Hardware Raid card. The Hard Drive Configuration is: 4 x 2TB Western Digital drives setup as a Raid 1+0 array providing 4TB of space with what we believed to be optimal performance and redundancy. We had two volumes / partitions configured on the array, one 120GB for the OS and the remaining 3.8TB for data.
Everything was working fine when the server froze up. ON the Screen an error message said there is a problem with your Raid controller, Please open Apple Raid Utility.. Unfortunatly when we tried to do that we just got a spining beachball. We tried to open finder and it beachballed. We tried to force quit and nothing working. Finally we were left with no choice but to do a hard restart of the server and turn the machine off and then back on.
When the server came back on it would not boot up. We were greeting with the Folder with a Queston Mark. We booted from the Mac 10.6 Snow leopard Server Disk and opened up Apples Raid utility software. Much to our shock the Raid Set and the two Volumes were not shown in the Utility. However all 4 of the drives were listed and all being shown as Green light good status, but listed as "Roaming". We weren't sure what to do, the volumes weren't accesible since they didn't exist, the Raid set wasn't there, there was no way to run something like Data Rescue Recovery software. We tried calling Apple and have to wait until they open this morning. After looking online at various forums we came accross this problem with no solutions. Most of the people with the problems had the older 2006 Blue Raid card, and this appeared to be a common issue amoung others with the older card. I decided to try and re-create the Raid 1+0 set. However as soon as I did that I was prompted by Raid Utility that the drives I was selecting to use for the Raid set were already a part of another raid set and using them would delete the data on the set. I obviously canceled the process. Crazy enough the system knows the drives belong to a Raid set but doesn't realize it should know what the raid set information is.
We were using Mac OS 10.6.7 Snow Leopard Server, and I even tried installing and updating an external drive with 10.6.7 Server and booted from the drive from the machine and try to run Raid Utility. That did not work either. Any advice from anyone would be awesome. I'm worried what Apple is going to say when I do get a hold of them, the system is under Apple Care warranty. Thanks in advance for anyone's time.

I haven't lost data, but in my 2010 Mac Pro with 2009-vintage Apple RAID card, it has this Really Annoying Habit of constantly losing Disk 3 (the spare) in my 4x2 TB internal RAID5 array whenever I have to do a hard reboot.
I keep having to re-mark the now-"Roaming" drive as a Spare and then wait 8+ hours for it to rebuild the array ... grrr.
I saw an Apple KB article that suggests removing the Roaming disk and re-inserting it. Duh. Fat lot of good that did. Really wish there was some answer to this issue ... hard reboots should NOT cause array disks to go from "Assigned"/good to "Roaming"!

Advice on RAID Sets, Volume Sets, and RAID Levels of the Volume Sets using an Areca Controller

I have read through a lot of information on disk usage, storage rules for an editing rig, users inquiries/member responses in this forum and I thank each and every one of you – especially Harm.
In building my new workstation, I purchased five (5) WD 1T, 7k, 64M SATAIII hard drives and an Areca RAID card, ARC-1880ix-16-4G, which I plan to use primarily as my media/data disk array. The workstation will use a 128GB SATAIII SSD as the OS/program drive and I will transfer two (2) WD Raptor/10k SATA 70GB drives from my current system for pagefile/scratch/render use. I tentatively plan on using a mobo SATAIII port for the SSD and mobo SATA ports with a software RAID (level 0) for the 10k Raptors.
In reading the Areca Instruction manual, I am now considering exactly how I should configure the 5 physical 1TB drives in terms of RAID Level(s), Volume Sets, and RAID Sets. I must admit that I like the opportunity of allowing for a Dedicated Hot Spare as I am generally distrustful of the MTBF data that drive vendors tout and have the bad experience in the past of losing data from a mal-configured RAID array and a single drive hardware failure (admittedly, my fault!).
In line with the logic that one doesn’t want to perform disk reading while trying to write at the same time (or vice-versa), I am thinking the approach above should work OK in using the mobo disk interface and both software and external hardware RAID controllers without having to create separate RAID level configurations within a Volume Set or further dividing up the physical drives into separate RAID sets. I know in forum messages that Harm noted that he had 17 drives and I could envision a benefit to having separate RAID sets in that situation, but I am not at that point yet.
To some degree I think it might be best to just create one RAID Level on one Volume Set on one RAID Set, but want to solicit thoughts from veteran controller users on their workflows/thoughts in these regards.
Anyone care to share thoughts/perspectives? Thanks
Bill

Thanks for the speedy feedback Harm - I appreciate it.
I was thinking RAID level 3 as well.
Of course, it's always something! I purchased the Caviar Blacks by mistake - which are non-TLER. I will work with EggHead to return the ones I purchased and replace them with RE4 versions as I'm not thrilled about the possibility of the controller declaring the volume/disks degraded unnecessarily and although I have the DOS utility WDTLER where one is supposed to be able to enable/disable TLER on WD drives - I suspect WD is way beyond that now anyway with current builds.
I agree with you about just testing the performance of the options for the raptors - on the mobo and then on the controller. When I benchmark them I'll post the results in case others are curious.
Thanks again....off to EggHead!

Creating a mirrored raid set with a hard drive that already has data on it.

I have a hard drive that I keep my photos on, and want to create a mirrored raid set that includes this drive, with its data, and another drive. How can I do this without erasing the drive with my photos on them? I am running 10.7.5 if that matters.
Thanks for any help.

Creating a Mirrored RAID reformats the drive and loads a substantial RAID driver and some tables onto it. When completed, the drive is inherently a member of a RAID set, and will continue to be so even if moved to another Mac.
because of this, you cannot create a RAID directly on a standard drive that contains data already in any reasonable, risk-free way.
To amplify what The Hatter has said above, Mirrored RAID is not Backup. Mirrored RAID only increases mean time to repair to keep a drive failure from becoming a Data Disaster. You still need a Backup. Mirrored RAID does not protect you from deletions from user error, crazy software, or "just because".
I run a mirrored RAID in my Home Server, which contains all the Users files for everyone in the Household. And I also recognize (after being burned by it) that Mirrored RAID is helpful, but not a sufficient Backup by itself. I back up the Users Drive automatically to an External drive using Time Machine. [So what I am advising is not just theoretical, I am living what I am advising.]
With WD Black 1TB and other very good drives in the under US$100 range, there is really no reason NOT to invest in several drives for such an undertaking.

Macbook Pro with Dual hard drives. Scratch Disk, Memory 64bit, Raid, Set Up Questions.

Hello, this is my first post.
I just upgraded from the original 2006 17" Macbook Pro to a refurbished 13" Macbook Pro 2.53GHZ 4GB Ram (2009 model).
I bought the MCE Tech Optibay and installed it (if you dont know anything about it, ask me, its amazing.) So now I have 2x 500GB 7200RPM Seagate hard drives installed.
I am running Snow Leopard, CS3, Lightroom 1.4.
I have the main hard drive set up with Snow Leopard and all the Applications. I keep all my files on external firewire 800 drives, except files I am currently working on.
The second hard drive is set up as a scratch disk for Photoshop CS3 and that is it.
I am looking to upgrade to CS5 and Lightroom 3 here within this month or so. Or if I get anxious, tomorrow, haha.
I want to know the best setup I can do with my current set up with CS3 and for my future setup with CS5.
Any info will appreciated.
-Would some kind of raid set up with my internal drives be better? How does raid work with scratch disks?
-If I upgrade to 8GB memory in my macbook pro, would I even see a difference in performance if I didn't have a scratch disk? Since CS5 and Snow Leopard can use more memory in 64bit.
I think thats all I have on my brain right now. I may have more questions, or I can guarantee I will have more later.
Thanks alot.

First the scratch. Like you said, most everyone has a different take on scratch discs but I'd guess you're wasting one heck of a lot of hard drive space using all 500 GB for Scratch, did I read that right? If I did read it correctly YES, partition it and get some use out of it!!
I've got a unibody MBP 2.93GHz, OS 10.5.8, CS3 & PS 5 (running in 32bit mode), and 8 gigs of ram. I've partitioned the one 300 GB drive so 50GB is scratch, the other partition is for OS, & Apps, and documents (images).
I use LR 2 first than export to PS 5 to finish up. My photos get to be 300MB to 500MB in size and both versions of PS work on this setup just fine. Using PS 5 in 64 bit mode is faster opening files but NON of my plugin's are 64 bit yet, that's why I'm still stuck in 32 bit mode.
Not knowing what size or kind of files you work on makes giving advice a bit tough but try setting the status indicator (don't know the right name for it) in the bottom left corner of any PS open file to "Efficiency" and watch what happens when you process your files. I rarely see mine drop below 90%, I've got the usable RAM in PS Prefs set to it's max suggested, cut way back on History and Cache.
Can't wait for NIK and others to offer their plugin in 64 bit, later this year is what I was told.
There used to be an old "rule of thumb" with old version of PS about Scratch disc size. I don't remember exactly but it may have been 3 to 5 times the size of your biggest file??
Good luck, Alan

Volumes and raid sets disappeared

I booted my machine and it gave me a question mark folder I booted it off an external drive but the internal bay hdds arent mounting. When I was looking through raid utility it says they are all good and viable disks in roaming but no raid sets or volumes are there anymore. This all happened to my xserve (2008 2.8ghz 4gb ram) Three apple brand hdd at 1TB(in a raid 5 configuration) the os I had installed on the external hdd was 10.5.3..... any ideas or thoughts to getting the raid sets or volumes back.... also Disk utility still doesnt recogonize the three internal bays is that cause for concern or do you have to have a raid set and volume before disk utility to recogonize it. Thank you for your time and insight to my problem!

Use this guide:
RAID Utility - User Guide
To delete a RAID set or a volume:
1 Open RAID Utility and choose the volume or RAID set in the left column.
2 Click Delete Volume or Delete RAID Set.

Non supported character set: ...

Hi,
I'm sure I have a well known problem. When trying to post a new row to my DB (Oracle 9i Rel. 2) a java.sql.SQLException is thrown with the message Non supported character set: oracle-character-set-178
What I did to fix this error is:
- checked if nls_charset12.jar is in the classpath (it is)
- tried thin instead of oci (the error is the same)
- changed my NLS_LANG to ....UTF8 or ....WE8ISO8859P1 (didn't help also)
Does anybody know something else what I can do?
Thank you.
Axel

I found the solution myself.
I had to use the classes12.jar (etc) shipped with JDeveloper. I replaced these some day because OCI access didn't work with these classes. But now it seems to work.
