Hack a Snap Sever 1000?

Also, will an upgrade get me past the 137GB barrier? I've got 250's lying around (though 5400rpm drives are better for cooling). But first, I need an upgrade....

Thanks, everyone!

They are on the snap server ftp site (ours)

Email me and i will pass on the details too you

I did one of these upgrades on an original Snap 1000 a while back with the help of this forum. I was thinking about getting a Snap 2000 and doing the upgrade on it and I see from this forum that the 137mb barrier has been broken.
Two questions:
1. Are the drives that are being used ATA100 or can an ATA133 be used?
2. It seems the key is the OS upgrade for breaking the 137mb. Is this correct?

Thanks,
Chris

I presume you mean 137GB

It would seem so with Os v4, but not always, give it a try and see. Dont go all the way to 4.0.860, as that seems to cause a few problems.

I think better results have been obtained with ATA100, but ATA133 have been used

I just upgraded my Snapserver 4100 to Snap OS 4.0805 using the upgrade file and apparently the upgrade took without a hitch. However my disks are no longer accessable. Looking at Disk status it says "Uninitialized. Disk has not been validated yet. Please wait."

It has been like that for over two hours. This is a Raid 5 setup with four discs. I had recently replaced Disk one I with a 120Gb drive prior to this upgrade and set it up as a spare and the Raid used it and joined it with the other three, and it has been working fine with the three other 80Gb drives without any problems.

Am I missing something here? Is there something I should do to get the Snap to initialize? When the unit boots up, it checks all four drives and no drive lights stay on, nor does the disk light stay lit after it has rebooted.

In the log, it shows: File System : Set-up of logical disk failed. Device ID: 60000 (hex)

Figured it out. The upgrade didn't like the oddball hard drive size compared to the stock 80Gb units, so I unplugged it entirely and voila! the Snap server is up and running like a charm. I replugged in the 120Gb unit, reformatted it, and now it is in the process of repatriating it into the raid. Best part is no data loss. Cool!

I was recently sent a 'failing' snap server 2200. The data on the device is important to its owner, and I'm in the process of trying to recover whatever I can from the device.

I was provided with no documentation/software. I was only given the 2200 unit and its power supply. The system is no longer under warrantee.

From what I'm told, the device was left in its default raid configuration (raid 0).

The hard drives have been imaged in their original state, so messing around with various approaches to getting the data off is fine, plenty of spare hard drives witht he same LBA to use.

Heres where I need help:

Upon booting up, the system light comes on while the LAN light never does. There is some initial hard drive activity, but that doesnt last for more than a second or two.

If you modify the jumper settings on the hard drive you can get the system/disk lights to alternate. According to the snap appliance website this means you should call tech support... Not exactly helpful as the device is no longer under warantee. While the device is in this state, the lan light does come on and network activity is acknowledged by the activity light. The device itself does not appear to be addressable.

I have run through the process of 'resetting' the device through the sequence provided on the snap appliance website. The device resets fine by exhibits the same behavior as before the reset.

The options I have available (unless you all can come up with something else) seem to be either:

A) Buy a an identical 2200 and place the hard drives with the data into it. This is already in the works, but I still have time to also try:

B) Trying to rebuild the array manually to recover the data... This is where I need a lot more information maybe some of you could provide.

I am assuming (unless told otherwise) that the stripe was configured with IDE1 as the first device followed by IDE2. I'm also guessing (by analyzing the data on the drives looking for patterns) that the stripe size seems to be abnormally large (16384 sectors, or 8192KB). If this information is correct (which I have been unable to verify with any degree of certainty) I am still unable to determine the file system in use on these devices. I have heard that it is a variation of FFS (Open FFS?) or possibly UFS. Other snap devices I've worked with have used XFS. I can't seem to locate any clues on the drive that would point towards a valid partition table or information telling me what file system is in use. If I could determine what file system is in use, rebuilding the array (using the default settings) and mounting the raid image to recover the files may be possible.

So questions:

Has anyone successfully recovered the data off of a raid in this scenario? If so, how?
What file system is in use on the 2200 models?
What is the default stripe size for a raid 0 configuration?
Which is the first device in a 2 hard drive raid 0 default configuration?
Does the actual raid begin at an offset of the drive, or at the first sector?

Any other clues are welcome, I have some time before the replacement unit comes in to try more stuff out.

I made an effort to read every post that looked relevant in this thread, so I apologize if any of these questions have been answered before.

Thanks.

[re3dyb0y]

To my knowledge the only way that people have got data off is via another snap

The filesystem is believed to be XFS (as told by eu snap support)

There are some firms that specialize in data recovery including RAID's. Toms Hardware Guide had an article on them last month. Like Mr Google_uk said the only other way is by another snap, but I think they need to be the same OS version. Snap has made XFS file systems changes with different OS's. After you reset to factory setting you need to use Assist to locate and set the drive up. Default is 2 shares. The jumpers should me set as master on both drives. I run RAID 1 so if a drive fails I don't loose any data.

[HLouie]

Could any user of the Snap Server 2200 EM the information of the power supply information. I know it a external unit similar to the 1000 and 1100.

Thank-you

[re3dyb0y]

ftp://**** DOWN *****/

Is the Snap FTP

It does annoy me when people say they have read all the posts and cant find working links

That has been posted by me and others a few times, and therefore is there

Im not bothered about giving it out, it just annoys me when peiople says' something like that

It's Poogles

And anyway, mine are on C/s and it works

[dami2550]

OK, I've also read bunch of this thread, tried all kinds of workarounds and don't seem to get anywhere.

I have SnapServer 4100. Used to be BIOS 2.4.437, OS 3.4.807. Original 80GB hard drives.
Put WD 300GB hard drives in, 137GB each. no problems with creating RAID.

With help of Poogles (I swear I've tried that link long time ago, it didn't work, that's why I emailed you) I upgraded to 4.0.830. Same 137GB disks. Tried cable select, same issue. Tried reinit, still 137GB. Tried only single drive, same problem.

So I guess I just have wrong hardware, huh?

[re3dyb0y]

Thats fair enough, i was just making a point.

My FTP is down/has been down for a while, and aint going back up.

It would seem that you may have. Usually a reinit gives you some more space.

Some other work around may be avaliable

[boyelectric]

I have a 4000, Hardware 2.01, Bios 2.0.282, Software updated to 4.0.855, then .860.

The old drives are fine, raid is fine. Done the debug/ide command and the new drives (Hitachi 250GB) all come out at 137GB. They work fine like this, and I can make a raid fine, but just not the LBA support.

Does anyone have tricks for those of us who are left out in the cold?

I also tried adding the drives in one at a time or all at once, and still not seeing the full capacity.

I also have done the reinit, several times, I've even tried a cold restart to try to jog its little brain... no avail.

(4) Hitachi DeskStar 7K250 - 250 GB - ATA-100, 7200 rpm, 8MB buffer

I remember reading on the forum that the LBA is locked out on the 4000. Snap did not want the 4000 out preform there newer 4100.

There is a "ide 48bitLBACounter" flag that is turned off. But I do not know the command to turn it on. Use the debug to set.

Poogles_uk may be better qualified to answer this question.

I am trying to convert my Snap 1100 into a Snap 2200 using the info supplied in the forum.

I have :
Added additional drive
debug mode
bios unlock
bios model 0
bios lock

I can now see 2 drives and format them. What I really want to do is configure them as JBOD (or raid0)
I was expecting there to now be a 'Configure Disks' option under disk utilities but there is not. I have tried a hard reset and have re-applied the firmware but still no option.

Has anyone got this to work?And if so what did I miss?

Can someone give the the url in snap that gives you the 'Configure Disks' page to see if I can forcibly get there . ie http://203.4.71.116/config?Func=xxxx

I got it to work once a few months ago. I wasn't able to get the configure disks option to pop up though so I used debug commands to set it up instead. The URL for Configure Disks (I pulled this off of my 2200) is:

http://snapserverIP/config?Func=DiskConfigureSend

Hope this helps.
Cheers,

[re3dyb0y]

Yeah.

I presume by updating the firmware you mean the OS?


Blue - I'll have to get back to you, its been a while since i played with my snap.

Rob (int 20h) may be able to help in the mean time.



Also, im going to have a look at altering the OS. Somepoint this weekend. Rob, if you got any further can you give me a shout to say what you've done!


Cheers

Hello,

I just wanted to leave a message saying thank you to all who have posted information on modifying snap servers to accommodate larger drives. I have been looking for this information for a long time and this was the shining star find. I purchased a new snap server 1100 from ebay with a puny 80gb drive, and after following the helpful hints from previous posters, I was able to slap a nice 400gb seagate into it with absolutely 0 problems! Once again, thank you very much.

Oh, and here is how I did it in case that would help anyone else.

Made the digital dolly boot cd.
Removed snap HD and set it as master.
Set new larger drive as slave.
Connected them into my PC.
Booted from DD cd.
Chose copy raw data/partition.
Selected master as source, slave as destination.
Let it copy 3% of 80gb (2.4GB), then turned off PC.
Set the new drive as master and slapped it into the snap.
Logged into http://snapserver/config/debug and gave it the:
"config devices format 10000 /reinit" command.
Rebooted the snap and waited for the format.
Was greeted with a pleasing drive space of 377GB (lost quite a bit to format waste but oh well)
Thats it. Thanks again!

[re3dyb0y]

I dont think it is format waste

Most hard drives when formatted lose some space. So that would probably be about right, i have seen on 200gb drives, losing up to 13gb, and there aint really much you can do about it.

How come you let it copy 3%? Was that your guess on the OS and a bit more space?

Poogles,

As far as the 3%, yea.. im sure the OS wasnt larger than a 100MB or so, but I just did 3% cause I thought it was better to err on the large side.


Question: Since I have been playing with this thing for the past ten hours.. I have dumped about 170GBs onto it but it seems to peak at a transfer rate of 4.98MB/sec, man thats slow. Is everyone else getting something similar to that too? I can live with it because its alot of space up 24/7 but if there is a way to optimize it I would like to know. Thanks.

[re3dyb0y]

That sounds about what most people have got. Read joes article. well to windows anyway

I believe if you have NFS with linux box you can copy quicker


The OS is ~ 30mb in the .sup file
