You're pretty much right on target. Linux JFS and AIX JFS2 were branched from the same base code, but are a little bit different on disk. (The biggest difference is big vs. little-endian.) I don't think it would be difficult to adapt the JFS code to grok JFS2 if the JFS2 specs were available. > Also, (and this is really a rhetorical question), what was the point > in coding AIX LVM support in EVMS if AIX filesystem support was not > intended in Linux for JFS? My guess is just for completeness. It allows the future development of Linux JFS2, or it allows a Linux file system to reside in an AIX volume group even if it couldn't be used by AIX. > Thanks, > > Leigh. -- David Kleikamp IBM Linux Technology Center _______________________________________________ Jfs-discussion mailing list [EMAIL PROTECTED] http://www-124.ibm.com/developerworks/oss/mailman/listinfo/jfs-discussion
