[Spacewalk-list] Invalid cross-device link error

[Pierre Casenove]

Hello,
I've straced spacewalk-repo-sync call.
Here is the error:
stat("/data/satellite/redhat/1/bbe/mrepo/0.8.7-2.el5/noarch/bbe01b9ea61f85f4892dedc0fbb89b73/mrepo-0.8.7-2.el5.noarch.rpm",
0x7fff4f62f540) = -1 ENOENT (No such file or directory)
stat("/data/satellite/redhat/1/bbe/mrepo/0.8.7-2.el5/noarch/bbe01b9ea61f85f4892dedc0fbb89b73",
{st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
rename("/var/www/html/pub/epel/5/epel5-x86_64/mrepo-0.8.7-2.el5.noarch.rpm",
"/data/satellite/redhat/1/bbe/mrepo/0.8.7-2.el5/noarch/bbe01b9ea61f85f4892dedc0fbb89b73/mrepo-0.8.7-2.el5.noarch.rpm")
= -1 EXDEV (Invalid cross-device link)

/data/satellite is Spacewalk mount_point
/var/www/html/pub/epel/5/epel5-x86_64 is where the rpm is stored
locally on the server. It gets here using reposync.
Folder /data/satellite/redhat/1/bbe/mrepo/0.8.7-2.el5/noarch/bbe01b9ea61f85f4892dedc0fbb89b73/
is correctly created.

I've also dug a bit in bugzilla and found BZ 676369 being corrected
for spacewalk 1.6. And this commit in particular:
2dbe4deade884d410f93bfcd30947bb77dd18e88
-    pkgfd = os.open(packagePath, os.O_WRONLY | os.O_CREAT | os.O_TRUNC)
-    os.lseek(fd, 0, 0)
-    while 1:
-        buffer = os.read(fd, 65536)
-        if not buffer:
-            break
-        n = os.write(pkgfd, buffer)
-        if n != len(buffer):
-            # Error writing to the file
-            raise IOError, "Wrote %s out of %s bytes in file %s" % (
-                n, len(buffer), packagePath)
-    os.close(pkgfd)
+    os.rename(filename, packagePath)
     # set the path perms readable by all users
-    setPermsPath(packagePath, chmod=0644)
+    os.chmod(packagePath, 0644)


This patch introduces the use of os.rename command... which seems to
be a problem with local repositories.

Thanks in advance for your help,

Pierre
