zfs discuss - Mar 2008 - Solaris 10 x86 + ZFS / NFS server "cp" problem with AIX

Friends,
I have recently built a file server on x2200 with solaris x86 having zfs
(version4) and running NFS version2 & samba.

the AIX 5.2 & AIX 5.2 client give error while running command "cp -R
<zfs_nfs_mount_source> <zfs_nfs_mount_desticantion> as below:
cp: 0653-440 directory/1: name too long.
cp: 0653-438 cannot read directory directory/1.
 and the cp core dumps in AIX.

Can someone please help

Thanks

I think someone from the AIX camp is probably better suited to answering 
this, as they hopefully understand under which circumstances AIX''s cp 
would spit out this kind of error message.

Hi
seems like CR
6538383 "cp -r" to AIX local dir from NFS-mounted ZFS dir complains
"cp:
0653-440 <dir> : name too long."

seesm adding -p will get past this one or using find as in:

find . | cpio -pdmu

else copied in from CR
{
"There is an old problem with scandir() in libc that was fixed by the 
following APARs:
AIX 5.2: IY59427
AIX 5.3: IY60062

I can''t be certain this is the same problem, but it looks highly
likely.
There is no APAR for AIX 5.1 as it is out of support. If my fix levels 
are correct, if you have installed 5.2.0.50 (or later) or 5.3.0.10 (or 
later) or any level of 6.1 then you''ll have the fix."
}

Enda

I know nothing of AIX, but as a guess out of air:

Since it''s a recursive copy, is it possible one of the filenames in the
the tree is just really long or the directory structures are so deep that it
passes some AIX limit?

This is almost certainly an instance of 6538383 in our bug database. 
scandir() is indeed broken on AIX, this is not a ZFS bug.  If you have 
IBM support, you need to file something called a PMR with them to get 
the ball rolling on a fix.  It''s possible someone at Sun opened one 
already, I''m not certain.

The workaround is to use a program that doesn''t rely on scandir() to do
the copying, tar or cpio as previously mentioned.  Adding the -p option 
to cp appeared to be a workaround at one point, but that was a red 
herring, the failure with cp can be intermittent as it involves 
scandir() scribbling somewhat randomly over memory.
