Things may have changed from when we wrote the Distributions Redbook, but at that time, Reiserfs was not endian-safe. That is probably still true for 2.2 kernels (Alan Cox?) but I note that Red Hat's distribution has it as an option for their 2.4-based distribution.
Creating a Reiser or ext3 file system involves issuing the mkfs command. By definition, that will clobber your data. One of the advantages of the ext3 file system is that it can be _mounted_ as an ext2 file system, once it's been created. This is handy if you have any tools that seem to choke on ext3. I haven't been hearing anything from anyone screaming about losing their data on Linux/390 by using the journaling file systems. I would love to hear about both successes and failures, if anyone has any to report. Mark Post -----Original Message----- From: Philip J.

My initial concern is how do we move from ext2 to either ext3 or Reiserfs? Does the data on the filesystem get erased during the conversion (I know I back everything up but I need to allocate time)? Are there known incompatibilities on linux/390? We are using SLES7. Regards, Philip J. Tully Manager z/VM and Linux/Z support 212.647.3208
