cpio input/output error

mattma · #1 11th September 2004, 08:50 AM

hello,

I'm trying to migrate an entire partition (~50gb) from one server (rh9) to another (fedora core 2). What I'm doing is mounting the old partition from the old server on the new server using samba. then i use

find /mnt -depth -print | cpio -pdmvu .

this file copy command has always worked for me in the past and it gets all the hidden .something files as well.

However, after a while, I end up with a

"Input/output error" on the console. Any ideas?

I'm not married to cpio, if anyone has another good way of migrating a large amount of files across the network with all hidden files intact, I'd be happy to hear it.

On the other hand, is having this error a sign that something is amiss on my new server?

Some other info that might be useful: The kernel I am using is the one that ships with fedora core 2. selinux was installed but /etc/sysconfig/selinux is marked as disabled - but I've read that a bug in the distro version of the kernel (my version) makes it enabled anyway, but permissive. The partition i am copying to is a software raid 5 (via fedora) with 3 disks.

thanks in advance,

matt ma

ok, I figured it out. The find command was timing out while waiting for cpio to complete copying all those files. It times out because it tries to hold on to a samba connection for hours. So the solution is simple, separate the commands -

find /mnt -depth -print > tmp.log
cat tmp.log | cpio -pdmvu .

Does it really copy hidden file?
If I run find . -depth -print I cannot see any dot file returned....
How can this be fixed/worked around?
