vmunix: rfs_read_common ; short page read messages

Hello all,

following is the message displayed in the messages file:
vmunix: rfs_read_common:vp=0xfffffc00160d66c0(type 5) short page read(asked: 5, got: 1)

can someone point out what does this mean?
Is it nfs related issue because the customer was taking a remote backup.

Re: vmunix: rfs_read_common ; short page read messages

without technical information about version etc it is very difficult to give you a clue.

In V5.1A there is a patch out there fixing some rfs_ problems and is NFS related.

So please install latest patchkit or have a look into the description of it.

Re: vmunix: rfs_read_common ; short page read messages

Hi,

At some point in code level BL17, a developper inserted some informational printf statements to verify a patch he developped for an race condition between AdvFs and NFS access.
The code was released but he forgot to remove the informational messages, so what you see is normally harmless.

In more recent code-levels this message is removed.

Johan.

Re: vmunix: rfs_read_common ; short page read messages

The system that I have is AS4100 and the os is tru64 unix version 5.1 .

Patch kit PK6 I have loaded. waiting for the customers reply. I was more inclined in knowing what exactly does it mean by short page read.i was having a doubt on the paging of the system.
If it was a coding mistake its just ok.

Regards and thanks all of you.

Re: vmunix: rfs_read_common ; short page read messages

rfs is nfs related, short page read means the length/number of expected pages is not correct.

Paging of system itself is not related...

Due to 5.1 patch may not be available because this version is unsupported.
