Hack a Snap Sever 1000?

Use digital dolly (dd) from the knoppix CD to copy the boot tracks. After you have installed it you will be required to reinit the drive to get full capacity.

There has been a few that have converted a 1000 to a 2000 model. Remember that these models use a software raid. You may not have enough ram in the 1000. I think it only has 24 meg, where the 2000 has 32 meg.

That last little bit went over my head; I am assuming it is some sort of app for Linux/Unix, of which I have ZERO experience...

I just successfully upgraded the 1000 I had using a clone program that was referred to back in the first few pages of this thread that operates under DOS. It was successful. I didn't really upgrade the drive that much, just went from a 40 to a 60 (all I had), but did it more for "when the hard drive fails" kind of thing.

Interesting to note on the software RAID. So, they actually implement software RAID in the 1000 series, since there isn't a hardware RAID chip in the unit? WOW, that is kind of odd, considering I have never seen a 1000 equipped with RAID, so it is interesting they they would have the feature built-in the software. -EDIT- Just re-read your reply. Are you saying the 2000/2200 also uses a software RAID solution as well? -END EDIT-

But, I guess what your telling me is it won't work? I am either going to go for a RAID 2x60, or a single 120Gig drive (don't want to fight the 137Gig barrier, which btw what determines whether you have this limitation or not? OS, BIOS version, etc?)

Thanks everyone,

PS. In all cases I am using the newest V3 OS. Haven't seen the need for V4 in my application yet.

The 2000 uses software raid, where the 2200 uses hardware. Major difference in performance.

UNIX has had software raid avaliable for years. The snaps use a modified XPS file systems. Most clone programs have problem with it, the reason for sugesting dd. You shoud check to see if you have full capacity of you drive. Since the clone software does not know the file structure used. If it does not, let me know and I will give you the debug command to correct it.

As for as large drives, generally a bios v2 or greater with v4.0.830 os will work. There is nothing wrong with v3.4.803 if you don't have a need for large drives.

Thank you blue68f100, you are truly a wealth of information!

Way back early on in the thread the poster also gave the debug command to reformat the newly installed drive to its full capacity. In my case, it worked just fine, I do have full drive capacity.

Thank you also for the information on the v4 OS. So I take it that is required for drives >137Gig. Not a problem, I will just stick with 120Gig size max.

Also, the software I have is version .805; I had a hard time re-finding it again after Adaptec bought out Snap Appliance. I had that software before, but deleted it when I upgraded a couple of our other Snaps. Anyway, I ended up retrieving it again from a cached page of Snap Appliance LOL, but I don't think its there anymore.

Since the 2000 uses software RAID as well, you are really tempting me to try out the 1000 with a pair of mobile 7200rpm drives, although that is kind of an expensive experiment. I can get the single WD RE 120 Gig drive for about $90 shipped. The two mobile drives will cost probably 3 times that much.

Ahh.....decisions, decisions....But it would be kind of cool to have a RAID Snap server in such a tiny package.

As far as performance, we just used them as simple file servers. In my case I am using them in the same fashion, but with FTP capabilities, so performance isn't a major concern, but I do have to ask...

In the end, isn't the speed of the server bottlenecked but its 10/100 network connection?

Thanks again for sharing your knowledge!

Be carefull with WD, most of their drives have a ATA133 interface. Snaps only work with ATA100. WD has a utility that allows you to manually set the ATA speed.
If its connected at 10base, I think you get a throughput of 3mbps. 100 base is in the 35mbps, I think.

Thanks for the heads up, I'll keep note of that.

I just got finished opening up the 1100 I have (haven't tried a drive upgrade on it yet).

Its very odd...The newer 1100 I have looks like an old Pentium I computer inside; Intel P166 CPU, I belive intel TX chipset, FPRam or maybe EDO, etc.

Inside my older 1000 resembles NOTHING like the 1100. I can't even identify any PC components inside the 1000. Most all the chips are made by "ST". There is no intel chips inside that I immediately saw...no intel CPU, no intel chipset, etc...

Also, the 1000's HD used "Cable Select" on the HD, and the 1100 used "Master/Slave" settings.

Very odd, just thought I'd point that out in case anyone was wondering.

You are right about the Intel Chip, thats the heart, slow. The ram is a edo-dimm 72 pin. If you have a ram chip the is upgradable, then you have the older model, v1.

Some of the early 1000's (v1) had the os stored in flashram like the 2000. It made it easy when the drive failed. Just install a new drive and the snap would do all the setup and installation. All you had to was setback and watch. After about 5-10 minutes you can reconnect to it and monitor the progress of the drive format.

Hi guys. I have just got a snap server 1000. I have tried to copy the image from the snap servers 10gig hard drive to a 200 gig hard drive I have. I think I messed somthin up because now the snap server wont boot to the 10gig hard drive any more. So I am just wondering if some one might have a image of there 10gig hard drive that you could loan to me. If I could do this how abouts would I do it?

Thanks
Rick

How did you try to copy the image?

I used the ultimate boot cd..

[re3dyb0y]

I don't know of a way with the UBCD....

File hosting is down atm, but email me, and i will get back to you

The general way is by using Knoppix

[rickytim]

poogles,
I got your email for the images. I have unzipped them and I do not know what I am sposed to do with the images now. Do I just copy the image to the hard drive I am going to be useing for the snap server?

Thanks
Rick

[re3dyb0y]

It is all explained in the last couple of pages.

So have a look, and if your stuck, give us a shout back, and we'll try to explain!


Sam

[rickytim]

Poogles I cant really find what I am looking for on the last couple of pages. I real do not know where even to start. I if you could please direct me some where that explanes how to put this image on to my hard drive. Also what one do you think I sould try to use? The 1000 or 2200 image?
Thanks
Rick

I just figured out how to bring up the debug command line in the Snap. I just had to go back through the posts; it was all there! Thanks for not telling me. I know I have to do some of the work myself.

Entering the URL Address: http://snapname/config/debug
-This brings up the Snap command line interface

I loaded Knoppix Linux v.4 onto one of my PCs running W2K Pro on NTFS and was frustrated at first because the Linux didn't recognize NTFS, even using the ntfs file system switch. So I couldn't access the image file!!

In this case I copied the snap hard disk image .bin file to a usb drive, which the Linux OS recognized and then I imaged the new Seagate drive for the Snap with that.

For those not familiar with Linux, like myself, getting the device listing of the USB devices took a little while, but typing the command: dmesg|grep usb listed the usb devices and, in my case, sda was the id of the drive.
-"mount -t auto /dev/sda /mnt" mounted the usb drive with the name of mnt.
---the -t auto, file switch automatically understood the FAT file system of the usb drive.
-typing "ls /mnt" brought up a listing of the files on the root of the usb drive for confirmation.

At first Snap didn't recognize the newly imaged drive. After playing around with a few partitioning utilities, I realized that the new Seagate must of had some info on the head of the drive and the snap image was not at the exact place the Snap expected. I couldn't get the Seagate DOS level DiskWizard to work, PartitionMagic 8 couldn't reclaim the full capacity of the drive and leave it in a "unallocated" state, so I went back to the Drive Management utility in W2K and deleted all the partitions on the drive. I think the disk utility has to "zero fill" the beginning of the drive, so no data is on the drive at all. Leave the drive "unallocated" with no partition.

I then reimaged the drive with the snap image and.....the Snap loved it and worked....but only at the 28GB of the image.

Entering the URL Address: http://snapname/config/debug
-This brings up the Snap command line interface
-Type in the command: "config devices format 10000 /reinit"
-This command configures the snap disk system to allow the full capacity of the drive
---The drive is formatted to full size on the server restart.

The new Seagate 7200 200GB drive does run a bit hotter than the original Quantum Fireball. I have ordered a new fan from Cyberguys. the Snap 1000 fan is a 40 x 40 x 10mm fan. Hopefully, that will keep it cool enough.

Thanks for all the help. These NAS boxes are sure neat!

That is part of it

[rickytim]

OK, I got Knoppix 4 but I still do not know what else to do. I need like setp by step instructions on what to do in knoppix to mount the image on to the hard drive.
Some one please help.
Rick

[blue68f100]

check you email for instructions.

blue68f100

[rickytim]

ok blue68f100 I followed you directions you sent me. But when I type "ls /mnt" It said you chould see a list of windows files. I do not get that. I only get auto, cdrom, cdrom1, floppy, hda1, and hdb1. Please let me know if I have to do somthing different to get this to work.
Thanks
Rick

[rickytim]

I just saw in your email I need to use a fat32 format. I will give it a try at work tomarrow then...
Thanks
Rick

[blue68f100]

The "ls /mnt" will give you a directory listing of what you mounted @ /mnt. (The "ls" is equivlent to a "dir" command in dos.) If you copied the snap1000.bin file to root of c:/ , you should have seen it. This is just a check to make sure the files (source and target) are properly set.

I do not want you to over write the boot track on your windows hard drive.

If you have a usb pin drive. Another option would be to copy the bin file to it. Then type "dmesg|grep usb" locate your drive then mount it with "mount -t auto /dev/usb? /mnt".

Then do the "ls /mnt" again and see if you see your files.

If mounted you can continue to copy the .bin file to the hard drive.

Winndows XP, 2000, and NT default to NTSF format, which supports large hd. Fat32 is restricted to <137gig.

Make sure you have the hard drive jumpers set correct. Either CS or M/S.
Knoppix v3.8 would not boot on my computer with SATA drives. The reason for keeping Win98 with Fat32 drives.

There seams to be alot of people having problems using dd. I tried to write the instructions to make it easy to follow. After you get it to work, give me feed back so I can update my instruction to help the next person.

David

[rickytim]

OK, I followed the instructions that you gave me blue68f100 but when I go and install the hard drive into my snap server and access the snap threw a web browser I get a error that there is no devices installed. I guess it does not recognize the hard drive. I am now stuck and don’t know what to do or try next. Please let me know what else I can try.
Thanks
Rick

[blue68f100]

If you still have the org 10gig drive, see it it boots. If it does I can give the the detalis to copy it's boot tracks to the new one.

Make sure you set the hard disk to master or what ever the original was.

What are the lights doing (sys & disk) on the front of the snap? If the disk light is solid, it may be doing some disk repair.

You may need to reset the unit back to factory settings after installing.
Then use assist to do the initial setup.

Depending on which version of the 1000 you have you may need to use the 2200 img file.

David

[rickytim]

Ok, the original hard drive I have tried to copy it over to the drive I want to replace it with. When I finished copying over the original hard drive I tried the drive I just copied the image to but it didn’t work. I then tired the original hard drive and that no longer works either. So I must of messed something up when copying over the original image.

I have already reset the server back to factory settings when I tried the drive using the DD command.

When I installed the DD command hard drive into the snap and powered it up after like 1min the lights would start blinking normally like if it was working. But about 1min later when I could view the snap online the hard drive activity light would go off.

I also have an image of a 2200 snap server I will try it now and see if it works.

Thanks
Rick

[rickytim]

I have loaded the snap2200 image but I am still getting the same problem that no disks where found...

[re3dyb0y]

Is this cannot be found, in the case you cannot get to the web interface?
