Description of Problem:
Creating a large ext2 filesystem on Smart Array 5300 may take an
extraordinarily long time to complete. The process starts out normally,
but slows during the creation of the inode tables.
Creating a filesytem of about 175gB on an ADG volume took about 8 to 10
minutes to complete. Creating the same filesystem when using the 2.4.3
tree downloaded fron kernel.org completed within a couple of minutes.

You filed this under i386, but reported observing the problem on an IA-64.
Have you observed this on i386 as well?
Please remember to file Itanium defects under ia64 in the future.
What beta version have you tried this with? What is the kernel version?
Florian La Roche
This was tried with Beta 3 and kernel 2.4.3.
Re-assigned to the kernel.
Al, is this the O(N^2) buffer algo ?
This defect considered SHOULD-FIX for Fairfax gold-release.
It would be very interesting to know if the 2.4.7-0.4 kernel still has this
behavior; the relevant kernelcode is totally rewritten to get rid of bad
algorithms and such.
Comments from Compaq Engineer
The comments from RedHat indicate they have their own 2.4.7 (version 2.4.7-
0.4). When will we see that? Or do they want to know if it's fixed in the
2.4.7-0.3 was released to the betatime about half an hour ago, that's the same
as 2.4.7-0.4 which will have a rpm depenency fix in it.
