NFS issue - Error performing inpage operation

[Annelise Wilken]

I have an rx4640 that has the following filesystems exported:

/disk1/live/data/roi
/disk1/live/data/ni

I have a windows 2000 PC that maps drives to each of the directories listed above. When the customer tries to copy files from her windows Pc to /disk1/live/data/ni this works fine, but when trying to cpoy files from the PC to /disk1/live/data/roi this hangs the session on the PC. (i.e the customer was using windows explorer - this explorer window hangs not the PC itself!)

I've looked on the unix box and there aren't any fails; timeouts or NFS errors in syslog. But on the windows PC they see the error "Error performing inpage operation"

Can anyone offer advice? Because the filesystems are on the same physical volume on the unix server I would have thought that neither of the shares would work???


Many thanks.

Have you checked the /etc/exports file to make sure they're both exported with read/write permission?

Hi,

Write permissions on the file systems for the PC user can be the issue. This can be verifired by checking /etc/exports of the server and the user can also try moving one file within the unix file system from his PC.

Hello,

Have a look at this page for more information,

Have checked /etc/exports and both are exported with rw permission for any user from any machine.

Not sure what else it can be????

[Ivan Ferreira]

What if you export only /disk1/live/data, and then map the sub directories? Or map /disk1/live/data and try to write to the subdirectories.

Have read through the document and it implies that it could be due to bad sectors on the disk - I'm think of asking the customer if I can run an fsck on the filesystem .... hopefully that will fix it. I would have thought I'd have seen some unix errors or at least read errors etc... but I'm not seeing anything, no mail errors ... nothing!!!

[MarkSyder]

If users on the unix system can write to the disc I wouldn't bother with fsck - the document was referring to discs which are physically attached to a PC and is probably of no use to you whatsoever.

At this stage I think I would suggest asking on the Microsoft forum - I think the problem is on that side rather than the unix side.

Yeah I think so to .... if it was a disk problem (and I've just been able to write to and read from the disk ok) then I'd see read errors or even bad block errors .... funny coz the windows people are saying its unix ..... and I've been saying it isn't ....will let you know what happens!!!!

Hi,

For performing a media test on the drive the best way will be to use dd for reading the whole disk, if any such error is there in media it will get reflected straight away.Also is not there any other windows client to test the same operation.

dd in read mode shall be

#dd if=/dev/vgxx/lvol? of=/dev/null bs=1024k

Where /dev/vgxx/lvol? is the device file for that LVOL which holds that file system.

Problem solved ....it turns out it was a problem with the nfs client on the windows PC - the windows PC was rebuilt and a different windows client installed - all works ok.

Thanks for everyones input!
