Re: [techtalk] Raid 1+0

2001-05-21 Thread s h

RAID 1+0 (or RAID 10 as I've always heard it) is a RAID-1 of RAID-0's. 
Create two separate RAID-0's first.  Then, create a RAID-1 using the two
arrays you've just created.  The RAID-10 array will be seen simply as a
single sd.

HTH,
Sally

I think what you may be referring to as RAID-5 is actually RAID-4. 
RAID-4 is a stripe set with a single dedicated parity disk.  RAID-5 is
similar to RAID-4 in that it is a stripe set with striped parity.  Data
gets striped across each drive, and each individual disk has parity bits
from all of the other drives.  Erm.  I didn't describe that very
clearly, but that's the best I can do without drawing pictures or
something :)

[techtalk] Apache SIGTERM

2001-05-23 Thread s h

Hi all,

I recently replaced the hard drive on my intranet webserver.  The old
one had Redhat 7.0 installed, running apache-1.3.12-25.  My intranet
site has a mysql database with a php frontend.  The packages I used were
mod_php-3.0.12-1, mod_php-mysql-3.0.12-1, mysql-server-3.23.22.6, and
mysql-2.32.22-6.  When I installed the new hard drive, I installed
Redhat 7.1, with apache-1.3.19-5.  I installed the same packages for php
and mysql as I had before, and copied over my old httpd.conf file, along
with the entire docroot, with cp -Rpd to retain permissions.  I thought
I had all my bases covered... but once I had all my packages installed,
httpd will not start.  /var/log/messages only repeats what I already
knew (httpd startup failed).  /var/log/httpd/error_log shows only this:

[Wed May 23 08:32:25 2001] [notice] Apache/1.3.19 (Unix) 
(Red-Hat/Linux) mod_ssl/2.8.1 OpenSSL/0.9.6 DAV/1.0.2 PHP/4.0.4pl1
mod_perl/1.24_01 configured -- resuming normal operations
[Wed May 23 08:32:25 2001] [notice] suEXEC mechanism enabled (wrapper:
/usr/sbin/suexec)
[Wed May 23 09:54:00 2001] [notice] caught SIGTERM, shutting down

Subsequent attempts to restart httpd only repeat the "caught SIGTERM,
shutting down" message, with no other details.

Has anyone ever run across a similar situation?  And are there any other
logs I can check that could shed any more light on what's going on?

TIA...

Sally

[techtalk] Kickstart woes

2001-06-20 Thread s h

Hi all,

I've currently been playing with Kickstart.  When I tried it out, it
booted the kernel on the disk, insmod'd the network card driver,
successfully got a dhcp address, and then insmod'd nfs.o.  It gives no
error messages at all; the last message is the nfs module line. 
However, the installation just aborts.  My ks.cfg is pasted below-- any
ideas will be much appreciated.

TIA,
Sally
