Snap 4100 orphaned drive question
Hi, i'm new here and to Snap server maint so I could be asking something easily fixed. I searched around and couldn't really find anything that answered my question.
The other day we had a storm and the power went out. After that the server powered back up and seemed to work fine. Later that day someone tried to access files on it(from a Mac) and it threw some error about not being able to mount the volume. I checked around the office and found no one could connect but the web panel was still up and functional, except that the disks were all labeled "offline". I powered it down and back up and still nothing. I checked the logs, which only went back as far as May 10, that after the power up after the storm, the entry "File System Check : FSCK fatal error = 32" is in after every boot. Also, the command "info device" spits out: Code:

Re: Snap 4100 orphaned drive question
If you want to manually format the the drive. Login as admin and get to the debug page. Enter "co de format 10008 /reinit" If it fails on this you will need to repace the drive. If it formats, Set it up as a active spare. The Snap will grab it and start the rebuild of the raid array.

Re: Snap 4100 orphaned drive question
And by formatting that single drive I shouldn't lose any data? I feel pretty confident that if anything happens to the data, the company may be in serious trouble. Thinking back I should have really pushed for some sort of secondary backup solution.

Re: Snap 4100 orphaned drive question
I'm a little curious about your situation. If only one of the drives is dead, I am not sure why all of the drives appear to be offline. When I had a disk fail in my 4100, the RAID volume showed as running in degraded mode, but I could still access data from it. Only drive 2 was offline, as it seized up and wouldn't spin anymore. Your problem sounds different.
I wouldn't try formatting anything just yet, even though you shouldn't lose any data if you try and format the drive that is orphaned. I would just replace the drive and set it up as a hot spare and see what happens. Hopefully it will just rebuild the array and go on it's merry way. I'm just wondering if you don't have a more serious problem with the motherboard or something...I hope not, it just sounds odd from the way you described it.

Re: Snap 4100 orphaned drive question
Jontz is correct you should be in degrade mode. Depending on which version of the OS, Degrade may not be an option. I'm pretty sure I would go ahead and get a replacement drive. Once they have a major problem its time to replace them ALL.
I though there was another user that could not access there data till the drive was replaced. I had one uses report that in degrade mode the speed was about 10% of normal, real slooow.

Re: Snap 4100 orphaned drive question
There was one time that the disk status page didn't freeze up and it displayed RAID5 running in degrade mode but it was only once. I havn't been able to get it back since.
I could replace the drive but the only spare I have lying around is an 80 gig Seagate(ST380021A) and the drives in the server are 61 gig Maxtors(5T060H6). Would mixing that Seagate cause problems? I've read around that mixing and matching is not recomended. EDIT: After checking through the log again, the "File System Check : FSCK fatal error = 32" isn't showing up after my last two boots. Ideas? |

Re: Snap 4100 orphaned drive question
You are right that its not good to mix. Normally snap says the drive needs to be within 2% of capacity. But if the dirive geometry is too far off, it causes problems. What do you have to loose. Install it, the unit should format it, then set it as a hot spare. If every thing goes right it will take the drive and start the resync/rebuild.

Re: Snap 4100 orphaned drive question
Checking the connections on the drives and board were the first thing I did. I even replaced the ribbon cables some extras I had lying around but the same thing happens.
I was thinking I would just throw the 80 in there as a temp until I could get some better drives. My first thought was to hook everything up to my machine and use that RAID reconstruction tool I saw mentioned on here but I don't know that that would work to well. EDIT: Now i've put the new drive in, it formatted on boot, I set it as a spare but the server still seems to freeze like I mentioned before after checking RAID5. I don't know how long i've let it run like that in the past so I think i'll just leave it alone and see what happens. Is there any possibility it's trying to rebuild the array during this time? Because it gives me no idication it's doing anything. No network access, no web access and the only light on the front panel is the system light that blinks ridiculously fast, a constant link light and a net light that flashes from time to time. If it is rebuilding, about how long will it take? Last edited by Reason_Man; 08-19-2006 at 02:07 PM. |

Changed cables? Many SNAP servers (with multiple drives), but not all, use cable select cables not standard IDE cable. While this may not be a problem in your case, and most certainly is not the orignal problem, changing the cables in the middle of this "MAY HAVE" created another problem in the process. Meaning, the new drive might have corrected your problem but changing the cables kept it from doing so. In fact this may be why your error messages changed and no longer showing a fatal disk error. Hey, just my 2 cents worth. I do not have a 4100, but my 4000 does in fact use cable select cables and changing them to standard IDE cables would be a problem. But as I said, Dave can correct me if I am wrong here and I will just shut up. Side Note: Different RAID controllers are more or less sensitive to the drives sizes in any type RAID that uses stripping, some will work, some will not, and the ones that will vary in how far they will go. I cannot speak for the controllers built into the SNAP servers. HOWEVER, I can tell you that from my experience, most RAID controllers in RAID 5 arrays using HOT SPARE will usualy NOT pick up a non identical drive to be used in a failed array. When non identical drives can be used, you usualy have to do it manualy as a general rule. Just a thought. Last edited by Phoenix32; 08-19-2006 at 03:57 PM. |

Re: Snap 4100 orphaned drive question
I'm just the back stop for you 4x00 users.
Quote:
Was the 80 gig clean or did it have a file structure on it? If so I hope it wasn't unix. You by chance didn't get the drives swaped around did you? I would remove the failed drive (or 80gig) all together and see if the unit comes up. If you have another 4100, I would move the drives over to it and test. If the data is criticle I would stop right now and see if I could locate the software for recovering the raid set. djontz is the 4100 user on the forum.

No, the 80 gig replaced drive 2(or 1 if we start at 0). I'll try taking the drive out all together. I do not have another server but I could look around for a cheap used one to stick my drives in. I got the server second hand so I don't have any extra software if any came with it. Is there a way I can pull the data from the drives without actually having to physically remove the drives? EDIT: Removing the drive does nothing but flash the drive 2 LED amber. Last edited by Reason_Man; 08-19-2006 at 04:58 PM. |

Re: Snap 4100 orphaned drive question
There was one user that installed the drives into a pc with a raid 5 controller. Then used a recovery/resync software external of the snap. The snaps use a XFS unix file system.
The OS is stored in flashram. There are several 4000 and 4100 units on ebay. I think the 4100 run a little cheaper because of there lack of upgrade ability. But they are a little faster than the 4000.

Re: Snap 4100 orphaned drive question
I just found an empty 4100 on ebay, enclosure only(+ board and PS). One dollar so I think i'll try there.
If I were to take the drives out of the server and into my machine, is there a particular setup I could have to use? Like, my board supports RAID but I only ave 2 IDE ports. Would I be able to set two drives master and two slave or what? |

Re: Snap 4100 orphaned drive question
Most MB do not support raid 5 only 0 or 1. You will have to find a controller that support raid 5. Search the threads for raid 5, xfs, recovery ... till you find the one with the user that did his.

Re: Snap 4100 orphaned drive question
WOW....lot of activity on this thread since this morning.
The fast flashing system disk is indeed NOT GOOD. I am convinced now that your problem is not a hard drive problem, or at least a single hard drive problem. Just out of curiosity, did the disk 2 light ever go amber when you had the original orphaned drive in there? Normally it would if there was a problem... If you set the new drive as a hot spare, it should immediately pick up the drive and put it back into the array. During this time, the unit is accessilbe via the web interface, and you can see the status of the raid rebuild. This proccess should take about 6 hours or so with 120 GB drives, so maybe half that with 60 GB drives. The fact that you are saying that it is frozen and seems to be in panic mode doesn't bode well. The problem with the 4100's is that the OS is in flashram. If there is something wrong with that flash, or any part of the motherboard, there is very little you can do to recover the data from the drives. You might try as blue suggested finding a PC raid 5 controller and trying to rebuild the array that way. I'd be interested to see your results. If you are going to pull the drives and put them in a PC to try and rebuild them, try putting a single blank drive in your 4100 and see what happens. I am guessing that it will still be in panic mode and won't install the OS like it should. If you are seriously interested in that snap on ebay, let me know. I am thinking about picking it up myself and I don't want to get into a bidding war with you if you need it. Phoenix, just FYI the IDE cables in a 4100 are not CS cables, they are straight IDE cables with only one drive connector on them. All four drives in a 4100 are set as master.

Re: Snap 4100 orphaned drive question
Sometimes you can recover with a image file to boot the snap, then reload the OS. Did that several times on my 2000. There is a special reset sequence to clear panic modes. I would check to see if your cooling fans are still working. Most hardware failures are due to heat.
I think your best bet on recovery is with another 4100. Before you install any drives, connect and verify the unit is in raid 5 and not JBOD. You may have to come up with some drives to do the initial setup if a debug cmd want force it into raid 5. If it was reset back to factory settings, it does not change the drive configuration.

For your information on 4000:
SN < 70700042-003 use M/S (40 ribbon connector) Version 3 and > CS (80 ribbon connector)

Re: Snap 4100 orphaned drive question
Yeah, I took everything out and reseated it as I know that can sometimes be the problem(i've run across more than one machine that wouldn't do anything just because certain things weren't seated properly).
I probably won't end up bidding on that server since there are 3 already at about 60$ and I can't wait 3 days for something that might end up costing me a couple hundred. If you know of any other place to get a relativly cheap, used 4100 let me know. So currently my only option is to either get a new server(doubtful) or find a machine with a RAID 5 controller? Can I get one as an expansion card? If I find one with RAID 5, how would I go about setting them up? Currently I have my Windows boot drive on a SATA connection with 2 IDE ports. Could I get a double ribbon cable and hook up the 4 drives to each? If so, how would I configure them as far as master and slave go? Then, how would Windows react to it? |

Re: Snap 4100 orphaned drive question
Your pc will destroy what's left on the drives. MS doesn't no squat when it comes to drives formated in something not MS.
Yes to a pci raid 5 controller. You need to find the post of the user that did it. You will need to match the raid controller chip on the snap. Does the unit come up with no drives installed? If not do a factory reset. Normal (NOT PANIC) if YES -> Use assist to locate and assign the IP address. iF NOT -> pull the power while the unit on. Reboot Did it come up Normal? IF NOT Pull power again and DO the factory reset again Did it come up normal this time? Once it comes up normal with no drives, login as admin and check you platform byte in debug. If it still indicates 4 drives. Power down and install/connect the drives Powerup. If it comes up check to see if you have lost more than one drive. If So you are having hardware problems. Their was 1 user that had a second drive fail 2-3 days after the first one. When this happens you are SOL. This is a lesson learned. All though we use raids that have protection/redundency, Backups are still required. There are compaines that specialize in raid recovery, and can provide quick turn around for $$$$$$$

Re: Snap 4100 orphaned drive question
I found the post on using the external raid controler. It was on a 4000. Need to verify same controller chip. But it's a start.
