Tarred files not being put on tape
Hi
I normally backup to tape using the following command in Solaris 9 on SUN Enterprise 3500 server:

Code:
tar cvf /dev/rmt/0n data

but after a power cut, the server went down without being shutdown since the UPS failed. Now when I issue the tar command I get the root (/) being full looks like it can't see the tape drive.
How can I get the tarred files being put on the tape?
Thanks

Can you post your error messages? If your / is full, which you can see with the command
Code:
df /

see if you can enlarge it (LVM?) or delete some rubbish files in /.

What OS are you using?

Please post a directory listing of your output device file name and any similar ones:

Code:
ls -la /dev/rmt/0*

If there is any connection between the filesystem full and the tar this should show what is wrong.

My OS is Solaris 9 on sun 3500 server.

I also realised that a file named 0n which is very huge is created in the location /dev/rmt any time I issue the tar command. I have been using this command for years without any problem.

Is it possible that you have been using the same command on this computer for years and that it has never written to the tape drive because it has always written a file to disc?

I guess that the first thing is to find out whether you have a tape drive fitted, the type of tape drive, what the device name should be, and whether the tape drive works.

A device name ending in "n" normally means "no rewind". Are you attempting to append to a tape or trying to do something else?

Hi All
I was able to resolve the problem by typing tapes at the /dev/rmt directory.
Thanks very much for your responses and efforts.
