    Raid Emergency

    Not sure if anyone will be able to help here but I figured I should at least try.

    Hello all,

    I am desperately posting here hoping to find a solution. I walked into my edit suite to find my Raid beeping. I went to see what was wrong and the status light was flashing red but nothing else. I checked with lacie raid manager all drives reported to be good except under the raid status it said PD Missing. Still not sure what that means but I went and physically gave the Raid a once over and all lights were blue showing that all mechanical elements including drives were fine except that *** red light was still flashing. As I always do if I have an issue I restarted the computer to see if it was just some kind of glitch. Since then my raid has been unreadable and everytime I restart my computer it asks me to initialize my drive. When I open Lacie Raid manager the virtual disk is now missing and the Raid shows up as Raid 5 but PD missing. I feel like I can salvage this but I'm sure with one wrong touch I will probably lose everything so I am waiting on a response from Lacie in the morning. However since I know I will not be able to sleep I figured I would try here to see if some could help ease my brain and anxiety. I didn't have everything backed up how ever I did have all the raw so I can rebuild the next episodes but I will need to start on it ASAP if there is not chance of saving this raid. Any help at this point is much appreciated.

    Cheers,
    John

    Re: Raid Emergency

    I'm not too familiar with Lacie units.  What type of raid is it?  0,1,5 or JBOD?

    Re: Raid Emergency

    It's telling you that a physical hard drive is missing. I would check the cables and the seating of the drives, to make sure something hasn't become disconnected.

    If you do get your drive back, you may still need to access the RAID management software to see if your virtual disk has come back, and that's going to depend on your RAID level. If you were on RAID 0 and the drive (or it's data) was damaged in some way, you may not be able to save the stripe. If you used a RAID level with redundancy, you may be able to recover. In either case, I would have your spare disk standing by.

    Re: Raid Emergency

    It was in Raid 5. The virtual disk is missing and from the looks of it I might not have a chance because I never did any background initializations on the unit before. I had no clue that I should of been doing that so I may have just learned a very important and expensive lesson. Just about to call Lacie so my fingers are crossed but I do feel it may be of no good. On to a very expensive data recovery

    PD stands for physical disk, so despite all the lights showing blue (which could just mean there's power to the drives), the management system is not aware that there's anything connected in that slot. This could be anything from a cable fault to a failed drive controller board. This could be why your virtual disk is not appearing.

    If you are forced into data recovery, there is software around that can interrogate RAID disk sets and recover some of your data. I've only done it on Windows, but essentially you buy a number of SATA caddies to hold the disks, hook them up to spare SATA ports on your computer and let the software do it's work. I managed to recover a good proportion of my failed NAS using this technique, but it does require a fair bit of time to set up and execute.

    Re: Raid Emergency

    Sounds serious. A RAID 5 drive should still work with one physical drive out of action.

    If the virtual drive has gone then either 2 or more drives have failed or there is a more serious controller issue.

    If the data is important then best don't do anything. Every step you take to try and recover could make actual recovery harder/more expensive.

    I'd pull it and put plan B into action re storage and continued work. See What Lacie say and go from there.

    Re: Raid Emergency

    zYep and that is where I'm at now. The raid is in a data recovery shop and I'm working on another raid for the time being trying to rebuild my projects. Thankfully there was less stuff on teh raid that wasn't backed up then I though at first. I guess I've learned my lessen now to always have a working backup just in case, especially when thedata recovery may cost as much as or double what buying a second raid would have been.

     

    WIth that being said anybody have any recomendation on best ways to back up a raid. I want to use something like timemachine where it just does it every week or so but I thought I read somewhere that time machine is no good for raid for some reason.

    Re: Raid Emergency

    Time machine can present all sorts of issues as it monitors the space for changes.

    I'm no fan of automated stuff. Its easy for it to break for some reason and you only find out too late.

    You can get software or create scripts but I generally find having an overall media management aproach works best.

    Inital media creaton from rushes at the start of a job can have the Avid media folder numbers managed to create sets of media in numbered folders. This makes backing up easier and a numbered folder (other than 1) won;t get added to.

    You then to just backup currently created media as and when. If you ingest a new batch then manage the numbered folders and back it up whne done. if making media as you go along, renders, titles etc its less critical so maybe every few days or once a week.

    An LTO tape system is the best but not cheap. Non RAID single USB 3 drives would be my choice. Simple and cheap.

    Re: Raid Emergency

    Thanks Pat,

     

    I do have an LTO system for achival backup which is great and I find actually quite affordable when you go GB per dollar. I'm looking more for something to keep a constant mirror of my raid (Almost like a raid 1 except not in a raid setup) so that if my raid were to fail and I haven't backed up a project yet I don't lose any info and don't have any downtime. More as a failsafe but not my main backup of everything.

    Re: Raid Emergency

    As the size of drives have increased and with products like Softraid being so good and decent eclosures so cheap, high capacity gold standard Raid 1+0 setups have become possible for average users. But I agree with Pat, a high capacity single drive backed up nightly is cheap insurance.
