hard links

[warmongr]

I have two partitions<br>
<br>
/dev/hda1<br>
/dev/hda5<br>
<br>
I want to link a directory on /hda1 to a directory on /hda5 ie.<br>
<br>
/home/ftp/mirrors/linux (/home is on /hda1)<br>
/usr1/mirrors/linux<br>
<br>
I want to link the 1st one to the second one.<br>
<br>
I used ln -d /usr1/mirrors/linux /home/ftp/mirrors/linux however I am getting an error message as follows:<br>
<br>
ln: cannot create hard link '`/usr1/mirrors/linux' to '/home/ftp/mirrors/linux': Invalid cross-device link. Any ideas.<br>
<br>
What is spawning this is I have a new ftp server and want to set this up like the old server. (Same partition settings) Is there another way to link them?<br>

Try using a symbolic link instead. (ln -s)

I would like to do as you suggest however that is not the way it is presently configured. I am trying to find out how this was accomplished and recreate it on the new ftp server.<br>
<br>
Thanks though,<br>

Any others<br>

Hmmm... 'ln -s' is the only way of linking directories (or files) across different file systems.<br>
<br>
Presumably, you're doing this because the partition on /dev/hda5 has the required amount of disk space? If so, then 'ln -s' should work for your requirements.<br>
<br>
There is something else you could do, though.<br>
<br>
Is the /usr1/mirrors/linux directory the only thing on that partition? Presumably, it isn't, so the next question is, can you make the required space as a new partition? If so, you can then simply 'mount' the partition under '/home/ftp/mirrors/linux'. I suspect this may be how it's set up on the old system you're transferring from. If 'df' shows '/home/ftp/mirrors/linux' as a seperate entry, then this is the case.<br>
<br>
There's a third way involving loopback filesystems, but it's a bit much to get into a this stage. (Plus, I've not set one up for quite a while ;^)<br>
<br>
HTH.

As always, you are correct. Had I applied a little unixism to my question I would have realized that hard links are inode dependent. ok, so I haven't had to think in a while. df does not show /home/ftp/mirrors/linux as a seperate entry and I will admit to being stumped on this one however I did as suggested and used a symbolic link and there is no harm, no foul and I can move on to my next emergency. <br>
<br>
Thanks all,<br>

Thanks for the compliment War, but just to warn folks, I'm not always correct. See some of my other posts for proof ;^)<br>
<br>
Glad things are working for you,<br>
