One of the most recent and enlightening things we tried was to hang a spare SCSI drive on an external connector on the RZ box, put an ext2 filesystem on it, and add a share for it in the smb.conf. A 32GB file copies perfectly to this share, obviously using the same Samba setup and network interface, which made me suspect an issue with the RZ disk array.
However, the RZ people asked us to try a different filesystem on this new share. First we tried reiserfs, which is what the RZ array uses, and we observed a failure mode very similar to when we copy to the main array. Then we tried XFS, which is also journalling, and it too failed, although in a different way.
However, when we just do a native copy in Linux from the SCSI drive to the main array, the 32GB file copies fine, so it would seem that neither resierfs in itself nor Samba in itself is choking on the huge files.
And yet I see in the archives a recent post from Leroy that he is using resierfs for 30GB files with no problems (although perhaps he doesn't have NT in the picture, I don't know.)
So what are the best options at this point? Huge files are intrinsic to our operations, but if we go with ext2 on the main array, it will take a long time to start up the RZ box. Should we try ext3, and if so, are there any possible complications we should be aware of?
Thanks. -Eric
