I have a DL360 with dual 1266MHz processors, 2GB memory, and two 18.2 GB 
hard drives mirrored using the integrated controller. Partitions are 
formatted as ext3. I have noticed that the backup is up to 10 times slower 
than similar systems we have using ext2 instead of ext3. I am not utilizing 
any of the journaling capabilities of the filesystem.

In addition, I have tried to upgrade the kernel from 2.4.7-10smp to 
2.4.9-34smp. I have tried using RHN and building one manually. In each 
case, the machine hangs after the "Uncompressing linux..." message comes up 
on the console. I have tried booting with 2.4.9-34 kernel with similar 
results.

Disk Config:

[root@la_app2 opt]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/ida/c0d0p2       3.8G  2.9G  768M  80% /
/dev/ida/c0d0p7       6.4G  414M  5.6G   7% /opt
none                  1.0G     0  1.0G   0% /dev/shm
/dev/ida/c0d0p6       2.5G  134M  2.2G   6% /var


[root@la_app2 opt]# mount
/dev/ida/c0d0p2 on / type ext3 (rw)
none on /proc type proc (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/ida/c0d0p7 on /opt type ext3 (rw)
none on /dev/shm type tmpfs (rw)
/dev/ida/c0d0p6 on /var type ext3 (rw)


Thank you,

Jim Zimmerman
