Yesterday, I installed the 1.0.1 patch against 2.4.5 on a machine at
work. The machine's a 2-cpu, 4gb ram machine (highmem 4gb enabled).
I've got 4 disks on a dual-channel megaraid controller, doing hardware
raid0 across all 4. I created a single, 273gb partition, and did an
mkfs.xfs on it. I then tried to create a 20gb file with:
dd if=/dev/zero of=/u01/bigassfile bs=4096 count=5242880
This gave me messages like:
Aug 9 14:59:10 dpdred2 kernel: __alloc_pages: 0-order allocation failed.
Aug 9 14:59:14 dpdred2 last message repeated 113 times
Aug 9 15:01:51 dpdred2 last message repeated 90 times
Aug 9 15:01:51 dpdred2 kernel: ed.

Aug 9 15:05:47 dpdred2 kernel: ed.
Aug 9 15:05:47 dpdred2 kernel: __alloc_pages: 0-order allocation failed.
The file was created successfully though...but the messages do tend to
put me on edge a bit. Copying a 64gb file from an NFS share to the
filesystem doesn't show any problems. I got the feeling from a
message in the archives that this might be a problem with the mainline
kernel's highmem code... would that be a reasonable assumption, or is
this an XFS issue? If it's related to the highmem issues, then I'd
need to upgrade to 2.4.7...are there release 1.0.1 patches against
2.4.7, or will I have to upgrade to the latest development snapshot?
If I have to upgrade to the latest development snapshot, is it stable
enough to use?
