Ignite Image Question.

Ramesh.K.R. — Wed, 06 Dec 2006 01:49:30 GMT

Hi Experts,

I have FTP'd ignite images over WAN. I want to ensure that the image is absolutely intact...

I have compared the size & cksum. Both are same (remote site & local). But the only difference i see is, when i say "file " it gives the following o/p:

remote site - gzip compressed
local - awk program text

Is this a problem ??
How else can i make sure that the ignite image i have FTP'd is absolutely intact ??

Thanks & Regards,
Ramesh.K.R.

Hello.

The only sure fire way would be to recover the image on a test server.

I do this every now and then on my site just to make sure the ignite backups are correct

Hi,

So, there is no other option ??

I just tried "gunzip" on the image. It gives the following error:

Unknown error

Does this mean a problem ?? OR is this expected ???

Hello again RAMESH.

I dont think there is a problem, what command did you use to create the image ?.

I you used the default setting the image was created in tar format if you specified the -m option and chose cpio then thats the reason for the problem

-m c | t Archive method: c for cpio
and t for tar. tar is the
default.

-c z | g | n Compression method: z for compress, g for gzip, or n for no compression. gzip is the default.

Ramesh.
If you used make_sys_image. here is what I found using man make_sys_image.

Note: Archives written to tape or raw disk cannot
be used directly; they must first be extracted
using dd onto a file system where they may be
accessed by an Ignite-UX server. To use a
directory that is an NFS mount point on the local
system, use -s local to specify the server
destination.

Hi,

We have used the following command:

/opt/ignite/bin/make_net_recovery -i -b -P s -l 0x00306EEA926D -s nuncas05 -display

Does this tell you anything ??

Hello.
Seeing your command line arguments i can tell you that the image created of the server is in tar format therefore gunzip gives you the error.

You probably could use tar to uncompressthe image, I would not recommend trying to uncompress it using tar, because I dont know what the result would be.

Ramesh don't you have another server were you could try to use this image too see if it works ?

Hi,

I think there are no other alternatives, but to check with actual recovery ...
Will try that only soon.

Thanks & Regards,
