Unable to copy a 6 GB file with cpio

SvenJ · 03-17-2006, 02:10 AM

I’m using Red Hat Enterprise Linux ES release 4 (Nahant Update 2).

When I try to copy a 6 GB file it fails:
find /data/TMP -print|cpio -padmuv /backup/bu0/
/backup/bu0//data/TMP
cpio: File /data/TMP/TMP.TMP grew, 0 new bytes not copied
/backup/bu0//data/TMP/TMP.TMP
3899392 blocks

There is a lot of space in /backup, and using cp instead of cpio works fine.

Is there a size limit on how big files cpio can handle?

Is there a better way to make a disk-to-disk backup?

What filesystem is the /backup folder in?

/dev/sdd1 on /backup type ext3 (rw)
It's on an external disk cabinet with RAID 10.

is the file still written to while you want to copy it?

There are no proceses that has the file opened. So the error message is wrong.
