Jones <rjones at redhat.com> Date: Wed, 19 Aug 2009 14:03:35 +0100 Subject: [PATCH] mke2fs: Use e4fsprogs programs if available. On RHEL 5, mke2fs is ancient, and there is a non-standard "mke4fs" binary which acts like the more recent mke2fs on Fedora. Since there are several annoyances and actual bugs in the ancient RHEL 5 mke2fs, use mke4fs instead if it's available. --- appliance/packagelist.in | 2 + daemon/ext2.c | 49 ++++++++++++++++++++++++++++++++++++++++...

So I have been playing with a RAID 10 f2 ( 2 disks far layout) setup...thanks for all of the advice..Now I am playing with the format and want to make sure I have it setup the best that I can, my raid was built using the raid 10 option with 2 disks with the layout=far, chunk size 512....now I read all of the docs I could find about format and stride and stripe size and this is what i came up

I've been thinking recently that we should re-enable DIR_INDEX in mke2fs by default. When it first came out, we had done this and were bitten by a few bugs in the code. However, this code has been in heavy use for several thousand filesystem years in Lustre, if not elsewhere, and I'm inclined to think it is pretty safe these days. Likewise, RHEL/FC have had RESIZE_INODE as a standard

The changes since the previous patch: - safe ADD_ARG macro for adding arguments to a fixed size stack array - support for testing functions that return RHashtable, ie. tune2fs-l. - add tests that set (tune2fs) and get (tune2fs-l) various parameters. - only one 'intervalbetweenchecks' parameter (in seconds) Rich.
