SCP failed I/0 error

[sam_25_1]

Hello Everyone,

When i am doing a scp to copy directory from one server to anaother i get the following eror message.

scp: /ohrprod.OFF.Jan-20-2008-014500.1: I/O error.

I was previous able to do a scp copy before, but now I am getting that error message.

The comand format is

scp -r @source ip:/source file / destination file.

The file size is more than 2 gb so i also did a fsadm -F vxfs -o large file /fiel system

I would be greatfully if any one could help me out fro teh same.

Thanks in advance.

Have a nice day.

Sam

Filesystem full on the remote system?

Are you sure your command took? Can you fsadm -F vxfs /mountpoint on the remote filesystem?

It is -o largefiles no space and plural. Just making sure you had the right -o option.

Hi dave,

thanks a lot for your speedy reply, i sincerly appreciate it.

yes there was i typing error,

the command whihch i executed was

fsadm-F vxfs -o largefiles / filesystem

wheni do a bdf comand there is nearly 20 gb of free space still left in it.

i was able to a scp copy on friday as i manually take a backup of the directory.. but today for soem reasons it goes through 100% and finally gives me I/O error
.

Please let me know what else can i do

You mentioned that you were able to do scp on friday?
what was the file size that day, was it more than 2 GB ??


is the target filesystem of the scp configured to allow large files? Have you tried say a local dd of /dev/random to create 2GB file in the target filesystem to make sure it can take 2GB file?

Is scp the only option to copy over the file ? If yes then,I would:

On source host:
split -b 1024m mybigfill /aaa/bbb/mbf

This will split your file into 1GiB files /aaa/bbb/mbfaa, /aaa/bbb/mbfab, /aaa/bbb/mbfac ...

Now scp these /aaa/bbb/mbf* files to the destination host.

On destination host:
cat /aaa/bbb/mbf* > mybigfile

Man split for details. Split will avoid the all your eggs in one basket problem

Hi Mirdul,

Thanks alot for your reply, Yes I was able to scp the file on friday and they were larger than 2 gb plus.

i even execute the fsadm command and check the echo $? and theoutput returned 0. so i beleive the fiel got excuted.

I have not tried the split command before, I would go through the man pages for it.

thanks alot for replying to both my querries

Sam,

Have a look at the following thread and check the ssh version:
