Ext3 users - Apr 2005 - (no subject)

Hello,

  How to upgrade existing ext3 partition to new features? Moved from
RHEL3 to RHEL4.

  I had to install from c0d0p6 so partition could not be reformated during
install.

  Thanks,

  Mindaugas

# dumpe2fs /dev/cciss/c0d0p1 | fgrep features
dumpe2fs 1.35 (28-Feb-2004)
Filesystem features:      has_journal ext_attr resize_inode dir_index
filetype needs_recovery sparse_super

# dumpe2fs /dev/cciss/c0d0p6 | fgrep features

In general, you don't; most features just happen automatically.  If you
want extended attributes, for example, just mount with -o user_xattr. 
Similarly, ACLs, large file support and so on all just get set
automatically when you request the feature.

The two main exceptions are htree and online resize.  Currently online
resize has to be enabled at mke2fs time, not dynamically.  And htree can
be set with "tune2fs -O dir_index", but if you want to convert
existing
directories to the htree format then you also need to run "e2fsck -D"
on
the filesystem.
