NFS copy problem

[Piet Timmers_1]

Hallo everybody,

We are using NFS to make it possible to mount an OpenVMS filesystem on a PC. On the PC we use NFS-Client software from Reflection. This works, but, when I want to copy a large (50Mb) file from the PC to the NFS disk it says:

Cannot copy .....: There is not enough free disk space.
Delete one or more files to free disk space and then try again.

Why is this?

The properties on the PC let you see that the NFS disk has over 38 Gb free.
SHOW DEVICE on the OpenVMS shows that the disk has over 38 Gb free.
Diskquota is not enabled on this disk, but it is on other disks.
I have created a large file, 100 Gb, on the disk, no problem.
I copied this file to a new version with /CONTIGOUS , no problem.

Any idea?

Greetings,
Piet Timmers

Hi Piet

I don't know Reflection NFS. But I know about some file size limitations. As far as I remember there are several products (ftp, sftp, NFS)(depends version) which are limited to 2 GB.

Piet,

which versions are involved here?
Acc. to the SPD, TCPIP V5.5 increases the limits for NFS V3 file system to 1 terabyte and to 4 GB on container file systems.

Just tried something : I enabled high water marking on the drive (on VMS) and copied 100K blocks (from remote VMS, have no PC NFS client).

It ended in error when trying to use NFS for file creation (file attributes write error).

May be this error is interpreted by reflection as "no space" ?

Everybody thanks for thinking, but the problem is solved!!



You want to know what we did??


Increased a timeout value, windows applications and error messages........hrrrr.

Thanks.

Piet,

Which timeout ? The high water marking makes NFS file operations take (a lot) longer. Increasing the timeout may help for the current size but give prblems again when you use files of e.g. 1GB.
