Cpio won't restore in a certain directory.

This is not a critical thing but an interesting thing I came across

Has anyone ever had a case where cpio would not restore files in a certain mounted directory

I am going through the process of replacing a few disk drives and found that when I create a directory /hmnt and mount a file system on it I can not do a cpio recover. I don't know why. I can mount the same file system on another mount point, a directory I created in /tmp the same way I created /hmnt (with the mkdir command) and cpio has no problem with it. I can touch or create files no problem from the command line. Cpio just sits there longer almost like its waiting on something.

Any ideas or answers?

Is this local filesystem or an NFS filesystem? The first thing I would do is umount the filesystem and do an ls -l mountpoint to see the mode of the underlying mountpoint directory. I'm betting they are very restrictive. When you run cpio, are you running as the same user as when you excute the other commands you mention?

Both directories that I used as mount points are 777 and I am root when I run the commands.

The only difference I can see in them is one is in the root directory and one is in /tmp

Do you have root access on the NFS mounted folder?

Without it root is restricted on the remote system.

Okay, humor me and do a few things and post the results:

umount the filesystem.

ls -l /
and then ls -l /tmp (if that is where the "good" mount is working)

Now mount the filesystem on /hmnt and do an ls -la /hmnt

bdf

df -kt

There is one more thing that could do you in. Consider the case where you are cpio'ing from a file /hmnt/my.cpio that is itself restoring /hmnt/my.cpio, the cpio image could overwrite itself. It would be a good idea to also
cpio -i[c]vt < my.cpio and post that listing.

I don't seem to have time to mess with this right now but when I get time, if the problem still exists I will bring it back up.

for now though I am closing the thread
thanks
