Cant see file on shared storage

[alan147]

Hello

I just set up some shared storage on a Netapp filer and connected two rhel 5 servers to it using iscsi. The storage has been partitioned and then mounted on both servers. Howerver when I write a file to the shared storage on one server I cannot see it on the other server. Any ideas what I have missed?

Thanks

Alan

Ive just noticed that if I un mount the partition the OS doesn't recognise the file

Before dropping the mount point

-rwxr-xr-x 1 root root 1.3G Jul 6 13:37 p10098816_112020_Linux-x86-64_1of7.zip

After droppiing the mount point and re mounting

?--------- ? ? ? ? ? p10098816_112020_Linux-x86-64_1of7.zip

Thanks again

Alan

What filesystem type are you using? Is it cluster-aware? (It needs to be!)

here is some information, go over it and compare how you did it, with the way they did it...

I was using EXT3.

When I write a file to the storage on one server I cannot see it on the other until I remount.

Thanks for your help.

ext3 is not a shared-access cluster aware filesystem; you'll need to use something more advanced if you wish to mount the filesystem on multiple systems simultaneously.

Thanks, I dont want to mess about with production database servers so i'll use NFS on the NetApp until the next rebuild of the DB servers when I'll look at GFS.
