File size limit for NFS

[Jim Naylor]

I have a system running HP-UX 11.11. I set up and automount for nfs and when I go to the nfs mount directory and do an ll I get several files that say not found.

# ll
./finance0508051316.dmp not found
./itemtest0509081011.dmp not found
./tcorp0510171519.dmp not found
./postest0509071413.dmp not found
./test0509071332.dmp not found
total 1961840
drwxr-xr-x 2 root sys 8192 Mar 24 2005 bex
-rw-rw---- 1 ora806 dba 150528 Nov 7 2003 dev030311071154.dmp
-rw-rw---- 1 ora806 dba 921 Nov 7 2003 dev030311071154.log
-rw-rw---- 1 ora806 dba 385024 Nov 11 2003 dev030311111052.dmp

The files that say not found are all over 2gig. Is there a file size limit on this?

Hi,

after what Robert suggested (hi Rob :-)check too if the filesystem has the largefiles option enabled.

fsadm -F vxfs /dev/vgXX/lvolX

should say what options are enabled on the filesystem.
If it is not then

(if you have OnlineJFS)
fsadm -F vxfs -o largefiles

(if you have not OnlineJFS)
umount /
mount -o largefiles /dev/vgXX/lvolX /


HTH.

Best regards,
Fabio

Are you using old automounter (not autofs)?

If so, it can only mount NFS using PV2, which is limited to 2GB file size. autofs can mount both PV2 and PV3, allowing you to have up to 128GB file size.
