What's the indication of "ext_attr" feature > and what are the reasons behind to have this feature? They are there simply to indicate that a given feature is present on the filesystem. They prevent old versions of the kernel and/or e2fsck tools from mistakenly operating on a filesystem with newer features, potentially corrupting things on disk or returning incorrect file contents. All remotely recent kernels have large file support for ext3, and all 2.6 ones (and many vendor-supplied 2.4 ones) have ext_attr, so you have to be running something pretty old to run into compatibility problems with either of those features. --Stephen _______________________________________________ Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
