For the record, note that migrating a system from one arch to another is completely unsupported and is likely to cause it to behave unpredictably in the future.

Upgrading from 32bit to 64bit

Many thanks, -T p.s. be really cool if all that stuff were built in Hi, Just out of curiosity why are you making the move from VB to KVM ? I currently make use of VB for most of my OS testing, but KVM looks like it has a bright future. Cheers Paul Hi Paul, I made the mistake of using VB with an enterprise level database and VB corrupted the database. The customer, my largest customer, eventually fired me over it. VB is a toy. I should have known better. KVM, on the other hand, has Red Hat behind it. I can not see the issues I have/had with VB not being fixed instantly. In my experience, Oracle could care less. -T

I'd expect this to work (but I admittedly don't know for sure) as long as it's really never ever mounted more than once. I think ext4 has no multiple mount protection. Any mistake may cause irreparable damage to the filesystem. Sharing it using NFS is certainly the safer option. -- Stephan Wiesand DESY -DV- Platanenenallee 6 15738 Zeuthen, Germany

Sharing iscsi luns between sl5.x and sl6.x
Hi all, Due to a certain app requeriments, I need to share an iscsi lun between two sl5.x and five sl6.x servers. This lun is formatted with ext4 fileysytem (I have used one of the sl5.x servers to do this). Can I expect some type of problems ??? Thanks. -- CL Martinez carlopmart {at} gmail {d0t} com
