I can't seem to get the read and write performance better than approximately 40MB/s on an ext2 file system. IMO, this is horrible performance for a 6-drive, hardware RAID 5 array. Please have a look at what I'm doing and let me know if anybody has any suggestions on how to improve the performance... System specs: ----------------- 2 x 2.8GHz Xeons 6GB RAM 1 3ware 9500S-12 2 x 6-drive,

We recently bought a 32-bit Xeon system with a 12-port 3Ware RAID card and a dozen 500GB drives. We wanted to create 4TB drive arrays; however, we soon discovered that there is about a 2.2TB drive array size limit on 32-bit hardware. Does that sound correct? Would replacing the 32-bit mobo/cpu with a 64-bit mobo/cpu allow us to use drive arrays larger than 2.2TB? Thanks.

I'm trying to enable ACI in openldap by: 1) Install the source rpm (rpm -ivh http://mirrors.kernel.org/centos/4/os/SRPMS/openldap-2.2.13-2.src.rpm) 2) Modify the spec file to include '--enable-aci' in the appropriate locations. I have even tried with the original (no aci) spec file. 3) Running 'rpmbuild -bb openldap.spec, which fails with the following output: <snip>

My goal is to be able to install to the drive array on the 3Ware controller card. 3Ware does provide a RH WS 3 driver that I've tried to use; however, the RH Enterprise 3 WS driver doesn't work since that kernel is older than the CentOS-3.1 install kernel. I'm trying to create a centOS-3.1 installation driver disk for the 3ware 9500S card; however, I'm not having much luck.

Why can't non-uid 0 users have more than 1024 file descriptors when logging in via ssh? I'm trying to allow a user to have a hard limit of 8192 file descriptors(system defaults to 1024) via the following setting in /etc/security/limits.conf: jdoe hard nofile 8192 But when jdoe logs in via ssh and does 'ulimit -Hn' he gets '1024' as a response. If he tries to
