RAID sets and volumes

I am trying to set up a RAID5 but am having trouble with the volumes.  My RAID set is 5.23TB but my Volume is only 2TB.  I am creating a second volume of 3.23TB. Is there a way to combine the two volumes into one volume of 5.23TB to match the RAID set?

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.

  • How do I remove one failing hard drive from raid set and replace with new one

    Last Friday apparently one of my raid drives started failing.
    As I mentioned on this forum I started getting continous beeping.
    I was finally able to get the raid working at a degraded level.  I ordered a replacement hard drive which is arriving today.
    (In the meantime I made twice daily backups of my work.....)
    Below was the message I got from the browser based raid software:

    (See this earlier thread if you wish!)
    http://forums.adobe.com/thread/727867?tstart=0
    At one point when I did the checked the browser interface I saw the message Failed and Degraded
    As I said, I was able to work over the weekend on the degraded system.
    This morning I got the beeping again and did the rescue and now I am running a "full raid" without the notice that one raid was "Free".
    In any case, the new hard drive is arriving today.
    What steps should I take to incorporate the new drive into the raid system.
    I have one OS drive
    and 4 tb raid drives.   One needs to be replaced with the new one that I am getting today.
    Thanks

    Harm,
    Regarding your comment:
    Re: How do I remove one failing hard drive from raid set and replace with new one
    Please tell me how to read the serial number from an individual drive rather easily, without un-installing them:
    If you select the proper drive to change out, you only need to remove one drive and look at its serial number...
    Step 1: Identify bad drive serial number using Areca's tools
    Step 2: Turn off the computer
    Step 3: Remove what you think is the bad drive based on following your numbered cable method, marked hot-swap bays, whatever
    Step 4: Verify that the serial number matches the "bad drive" serial number from step 1; if it does great, proceed; if it does not match, go back to step 3
    Step 5: Change out the CORRECT drive - that's the bottom line for this whole procedure
    Cheers,
    Jim

  • RAID set and JBOD on same controller card?

    I'm planning to update my RAID from the current 4-disc software 0 in my MacPro to a RAID 5 with dedicated controller (for now) and here's what I'm planning (tentatively)
    • RAID 5 consisting of 8 discs, 4 inside 5.1 MacPro with MaxUpgrade's kit in use for SAS connectivity , and 4 more discs in a 1U rackmount SAS chassis, possibly OWC's new 'trayless' unit, or another similar chassis.
    • Areca RAID controller ARC-1880ix-12 is what I'm leaning towards at this time.
    I don't have the cash or demand (yet) for a system in a huge expansion chassis and 24 drives, but my the main thing I want to know, (since I've never had this many discs to play around with before) is when I create an 8 disc RAID 5 Array for storage, can I also connect another external chassis to the controller as a JBOD unit and have those drives therein function independently, with swap capability of single volumes? This would be very handy for individual cleint-drive backups and would free up my eSATA interface for file ingest and more flexibility.
    I do know I would have to get an adapter to run more than one external SAS connection cause the Card only has one External SAS port as is. I may go with a different card with more channels for more future expansion, but it will more than likely have more internal ports than external.

    your system is on that RAID0?
    do you regularly clone your system, for when, (not in case), the RAID0 fails?
    Yes, when working I backup the data ideally after every time I add footage to the RAID, if not at least once daily.
    have you considered the added security of RAID6 (if your going to have that many drives . . .)
    I have, and it will probably be the next step if I go to a RAID larger than 8 discs. IF I do start getting the need for 16+ I may go to a RAID 10.
    when you mean storage, do you mean like archival, past projects type storage, or current working projects drive space?
    Working projects. Also will look into LTO for archival in the future if the demand necessitates it.
    can I also connect another external chassis to the controller as a JBOD unit and have those drives therein function independently, with swap capability of single volumes?
    yes
    Thank you, this is the main question I had, do you have a specific experience such as this you would share?

    you're describing SAS expander. You can easily have more than 200 drives connected.
    No I'm describing a PCI plate SFF-8087 to SFF-8088 Adapter, like this one:
    http://www.pc-pitstop.com/sascablesadapters/AD8788-4.asp
    Like I said, most of the cards I'm looking at have more internal 8087 ports than the external 8088 ports.
    what kind of work are you doing? Vidéo, audio? One project at a time, or parallel projects? Alone or with others (colleagues, employees)? The Caldigit system looks nice for large teams of people.
    This would be a mobile installation, with me as a single operator handling digital video footage, so this would be direct attached storage, no network interface necessary. Usually one project at a time, but if I get busier hopefully more than one.

  • My phone will not ring when i get a call i have checked setting and volume is up

    only had phone 1 week have 3 phones 1 itunes acount how do i set up multiple acounts in itune it keeps syncing all of our info

    no, my do not disturb was not on. and on the do not disturb, you still get calls from those in your favorites.  I turned off the vibrate with any call or alert and put the flashing led in the accessible section on. 
    but it should not do that.  it didn't even vibrate.  my girlfriend called me and texted me with phone on table while we were at dinner and nothing.  it went right to vm she said.  tower is full so something is wrong.

  • 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!

  • 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"! 

  • Can you move RAID sets around in Xsan?

    Hi All,
    My apologies if this is a dumb question--I haven't been able to find this anywhere.
    Given a SAN, if I shut it down, physically swap two RAID sets, and fire it back up, will Xsan still see everything just fine, or will I have just ruined my SAN?
    Yes, there is a reason we would want to do this.
    Thanks!
    -Josh

    Hi Josh,
    There are no dumb questions. I assume you mean you want to (for example) pull all 7 drives from half of 1 XServe-RAID and install them in exactly the same order in another XSR that is connected to the same FC switch? This shouldn't confuse XSAN- all the vital data is stored on the drives and not associated with a particular RAID controller. You cannot, however, remove a RAID set (LUN) from your volume.

  • Possible to increase the total size of a software raid set?

    Hi,
    I need to increase the size of a software raid set which is internally in one of the Xserves - originally it had 2x 400G drives.
    I've swapped drives into the raid so they are both now 500G drives.
    diskutil info drive XX (ie raid set) shows that the raid is still a 400G raid volume as expected.
    Question is - can I grow the Raid Total Size to use all the capacity of the member volumes?
    I guess the alternative is to remove the drives from the raid, enable raid on one of them and then add the other drive as a member... but this would mean I would have to take the raid offline.
    The raid sets are not my system disks.
    Any clues?
    TIA

    Thanks for your help.
    I rebuilt the array using enableRaid. Worked fine with Raid Volume offline for approx 5 minutes - although I had to degrade the array (and go bare with no mirror) twice in the process.
    In case anyone is interested, this is what the process was:
    1 Swap into Raid array larger drive (say, disk 2) and let array rebuild
    2 Disable file services.
    3 removefromraid disk 2 (leave it mounted).
    4 Unmount the raid set and eject drives (say, disk 1) Remove drive - it's the only original backup.
    5 enableRaid on disk 2
    Providing enableRaid is ok -
    6 Insert a fresh larger size drive in the place of the removed drive (disk 1)
    7 Unmount new drive and addToRaid
    8 (Rebuild array). Providing rebuilding ok -
    9 Start file services again.
    Data, permissions & ACLs were all intact. So now users can fill the rest of the raid up with more MP3s this week <sigh>
    Maybe not the best approach but it worked well for me.

  • Mac RAID card - expanding volume

    Hello - I have a Mac Pro with the Apple RAID card and a three disks RAID-0 (striped) volume (which is also the boot volume).
    Can I increase the volume capacity adding a disk to the volume, without having to format the raid set and start from a backup? In other words, can the raid card increase the volume capacity dinamically (and is there a guide for this?)
    thanks

    No. If you think of your RAID Array as three people playing cards, each gets dealt a card in turn. That is what happens with the RAID Array, data is written to each disk in turn.
    If you add another player to the game, in order to be fair you must deal again. That is exactly what happens with the RAID Array, you must reformat and start over again.

  • 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.

  • How to delete a RAID set in Disk Utility?

    I set up a mirrored RAID set with two 80GB disks on a 500MHz G4 "sawtooth", then installed Tiger successfully. Statup Disk on the Tiger DVD recognizes it as a valid startup disk, but it won't boot (stays on the white screen with the large apple).
    So, I decided to go back to two separate disks with no RAID, but Disk Utility won't seeem to let me delete a RAID set. It shows the volumes as locked (no apparent way to unlock them), and also doesn't allow me to format the underlying drives (bad file descriptor error).
    Any suggestions on how to undo a RAID set in Tiger?
    Thanks,
    0g
    G4 "Gigabit" Dual-500   Mac OS X (10.4.8)   1.5GB RAM, 1TB internal, SCSI, 802.11g, USB2.0

    Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. After the menubar appears select Disk Utility from the Utilities menu (Installer menu for Panther.) After DU loads select the main entry of the RAID (the one with the RAID size) then click on the RAID tab in the DU main window. Select the main RAID entry from the icon list (the one that says "Mirrored RAID Set" and should have the word "Online" in green. Then click the Delete button down below the list view.
    Be sure to backup first because this could cause complete loss of data.

  • C200 M2 forgets SW RAID Setting

    Hello Folks,
    I'm using the SW Raid feature of an C200 M2 Server. It works well, but if the server is disconnected from power for some hours it "forgets" the SW RAID Setting and boot order in the BIOS, defaults back to Enhanced mode. BIOS and CIMC Firmware are in actual SW state (updated with the
    ucs-c200-huu-1.4.2.iso ) Is there any solution for this problem?
    Thanks

    Hello Padma,
    there is no additional controller card, I'm only using the integrated Software RAID, the boot configuration consists only of the Raid volume. And it matches the shown configuration within the CIMC.
    I could reproduce it the last three times I had disconnected power for about 10 hours, last switch on after ~6 hours w/o power everything went fine. During the week the system sits in a production environment, I'll go and check if I can reproduce it again with >= 10 hours without power next weekend.
    I did the update all selection in the Host Upgrade Utility.

  • Why a Apple RAID controller card cannot delete a RAID set?

    Hi,
    I just have a problem with my RAID set created with RAID Utility.  My configuration is as follows:
         Mac Pro (early 2009 model) 2 x 2.66GHx Quad-Core, 16GB DDR3 1066Mhz Memory
         Apple RAID Card (HW Ver 2.00 and FW Ver E-1.3.20)
         1 x 1TB HD (Apple original) in Bay 1 as boot disk configured as Enhanced JBOD
         3 x 2TB HD (WD black series RE) in Bay 2 to Bay 4 configured as RAID 5
         Mac OS 10.7.4
    The RAID Utility showed the following messages:
    Degraded RAID set RS2 - No spare available for rebuild
    Degraded RAID set RS2 - No spare available for rebuild
    Degraded RAID set RS2
    Drive 3:50014ee20352f5e8 missing - Previous drive status was inuse
    Drive 3:50014ee20352f5e8 failure detected - Primary disk port unusable, previous drive status was inuse
    Furthermore, RAID Utility shows:

    4)  Bay 4 (RS2 RAID 5):  Assigned, verified, Status good, viable (degraded)
    It also showed "Severe Events" message:  "Degraded RAID set RS2 - No spare available for rebuild."
    I tried to delete the RAID set using Apple RAID Utility but nothing happened.  Can anyone help as I have to rebuild the RAID set from scratch?  Thanks.

    I have swapped the drives in bays and it is always bay 2. I'm coming to the conclusion that either the RAID card is failing in bay 2 or there is a Lion / Mountain Lion issue with the RAID card.
    I would say this is not "a Lion / Mountain Lion issue with the RAID card", as I have an "Early 2009 Mac Pro" that is running Snow Leopard (10.6.8), fully patched, that is exhibiting a similar issue, after about 4 years of no such problems.
    My RAID configuration is just like yours: 4x 2TB drives, with Bays 1 & 2 as RAID 1 and Bays 3 & 4 also as RAID 1.  I keep losing either Bay 1 or Bay 2 disk, and after reboot typically see it as a good disk, in the green, but now unassigned to a RAID set, and marked as "Roaming".  When I assign it as a spare, so far the RS1 RAID Set begins to rebuild, and things are okay for a short while.
    Initially this happened about once a month, starting about 3 months ago, now it is a weekly or several times weekly event.
    I've put in new disks (several), restored from a Time Machine backup, and just came in today to find the Bay 2 disk "Roaming".....
    I'm going to try a new Mac Pro RAID card, as I have a spare - just looking for information about whether the replacement RAID card will pick up the RAID sets from info cached on the disks (I hope!), or whether I have to newly create the RAID Sets & Volumes, and then re-populate from Time Machine / the old disks.
    I will say that I've been running 8  "Early 2008 Mac Pro" computers with RAID cards, each configured as above, and 4 "Early 2009 Mac Pro" computers similarly configured. These were all deployed between late 2008 and the beginning of 2010.  I've had little difficulty with them, and they've been wonderful when an actual disk failure has occurred.  I've had about 6 actual disk failures among all these setups.

  • 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?

  • 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.

Maybe you are looking for
