Thanks. The problem was I volunteered to add /bin to my path. That's
why it didn't work. But do I need to configure apache?

The t option in tar is just reading a table of contents not the actual
files. If you switch to the GNU tar, there is an option (W) that
attempts to verify the files as it writes them, which may be of a little
more help. There is more to your problem though if nothing returns any
kind of errors that you have run out of space. What commands are you
using to copy the tarred files onto tape?

Subject: Software RAID5 Performance Tuning
Date: Tue, 30 Jan 2001 15:51:40 GMT
Good morning,
Several months ago I decided I wanted LOTS of disk space.. mostly for
archiving digital photos, video, music and the like. I have a 9Gb
10kRPM Scsi drive for playback and any software I use frequently, but I
wanted somewhere to store stuff. I decided I would go with four 80Gb
Maxtor drives. I had two ATA/66 controllers (four buses) but they're
different brands. One's a Promise, and the other is a no-name from Best
Buy. I added md support to the kernel, built a nice 240Gb RAID-5 array,
and put ReiserFS on it for a journaling filesystem (fscking a 240gig
drive gives me the willies). I went with a 32kb chunk size on the
array, and Reiser is using 4k block sizes. /proc/mdstat has this to say
about the array:
+---------------
Personalities : [linear] [raid0] [raid1] [raid5]
read_ahead 1024 sectors
md0 : active raid5 hdk1[3] hdi1[2] hdg1[1] hde1[0]
240082944 blocks level 5, 32k chunk, algorithm 2 [4/4] [UUUU]
unused devices: <none>
+---------------
Now, my questions:
Is it normal for a set up like this to take over TWO DAYS for md to
build/rebuild the array?
Is it normal for my system to run at a constant load of 0.10 even when
it's not doing anything?
Is it normal for kapmd to be using 53% of the CPU?
PID USER PRI NI SIZE RSS SHARE STAT LIB %CPU %MEM TIME COMMAND
2 root 17 0 0 0 0 RW 0 53.0 0.0 16508m kapmd
Is it normal for me to only be achieving about 200kb/sec transfer rates
to the array? (My DSL modem can almost outpace this puppy, and the LAN
stomps it.)
The rest of the machine's stats:
PIII/500
128MB RAM
Two ethernet cards (home LAN router)
Linux 2.4.0-test9
Redhat 6.2 initially, with lots of changes
Could anyone give me some advice on performance tuning a software RAID
array under Linux? I'm going to spend a few days trying to decrease IO
latency in the kernel (online opinions seem to abound on this topic),
but I suspect I'm missing something big here. Should I be using much
larger chunk/block sizes because of the size of the array? Does having
two different brands of controllers do me in? Any suggestions on a
systematic way of collecting more performance data?
With the array taking two days to build, trial-and-error is pretty much
out of the question. ;)
Any help is appreciated!

I had a peep at the hardware compatibility lists, and it looks as
though XFree86 does not support your graphics card. This means that
you will almost certainly not be able to use X if you install Linux.

Well, programs that are only available as binaries for Linux/i386
(Staroffice etc.) will not run under Linux/alpha anyway. Programs
that are available with the source code will (normally) compile for
Digital Unix; binaries will also probably be available from the GNU
sites. Many of them (emacs, gnuplot...) will probably already be
installed. However, I accept that it will be easier to install
software on a Linux machine because of the availability of
debs/rpms. Which programs in particular do you want to use?

No, it's not "state granted" If it was, they wouldn't have been

Must be why Microsoft has been REPEATEDLY **CONVICTED** in Federal court

Subject: Re: Slow Disk Check for Large Drives
Date: Tue, 30 Jan 2001 16:48:17 GMT
You probably want a Journaling Filesystem. A Journaling FS keeps a log
of every write transaction, so if a power failure occurs, the filesystem
is able to use that log to 'rollback' to before the write operation, and
continue without lengthy scans of the filesystem to try and find errors.
My personal favorite is ReiserFS (http://www.reiserfs.com/) and I'm
currently using it on a 240Gb RAID-5 array (four 80Gig drives).
Recovery after a power failure mounts the filesystem almost instantly...
(though the RAID array takes a while to resynch. Fortunately Linux
allows you to use the array even while it's busy resynching.)
If you're not running RAID, however, Reiser will give you near
instantaneous remounts after a power failure. They've also been able to
tweak out some pretty hefty performance improvements over the now
somewhat-antiquated ext2 filesystem.
Some other choices:
ext3 - Replacement for ext2 with journaling capabilities
http://olstrans.sourceforge.net/release/OLS2000-ext3/OLS2000-ext3.html
jfs - A port to Linux of IBM's journaling FS.
http://oss.software.ibm.com/developerworks/opensource/jfs/
xfs - A port ot Linux of SGI's journaling FS. On IRIX it's arguably
the most robust *nix filesystem available.
http://oss.sgi.com/projects/xfs/
(anyone know of any others?)

st = (Scsi Tape) driver, 0 = 1st drive, m = mode; prepended
n = non-rewinding
See "/usr/src/linux/Documentation/devices.txt" and "man stinit".
Some application expect "/dev/tape" to be a symlink to the real drive.

It is state granted. That is precisely what patents and copyright are--
state granted monopolies. It used to be that there was a trade off--
they were granted only if they were published clearly for anyone to
read. Now adays you can copyright and trade secret at the same time. Ie
copyright in many situations has become simply a centrally planned,
state granted monopoly to allow friends of the government to make money.
That that same company could also engage in practices which contraven
other laws, or that different branches of the government could work at
cross purposes is hardly surprising. Lets see how Bush handles the
Microsoft case.

These are just environment variable settings. To see what effect they have,
you should look at ifup and ifup-ppp (and the corresponding ifdown) and
at the functions in network-functions. You might get some help here:

Subject: CDROM detected at boot, can't mount
Date: Tue, 30 Jan 2001 17:44:05 GMT
CDROM drive on my Mandrake 7.02 system is detected (in /var/log/dmesg as
/dev/hdc) but can't be mounted (mount /dev/cdrom /mnt/cdrom) reporting
"not a valid block device" or some such wording to that effect. The odd
thing is that the very same CDROM drive worked fine for loading the OS.
Everything else in the system is working fine. The CDROM drive is a LG
8080 type (CD-RW) as master alone on the 2nd IDE channel of a
few-years-old IBM box.
What am I doing wrong?

There are a few things that come to mind. One is physically
making it impossible for a normal user to power the system
down. If staff is unable to re-configure the system (it
is not a trivial hack either for hardware or for the systems
admin software), then perhaps hiring an outside consultant would
be approriate. Basically you want only the appropriate people
(systems administrators) to be able to power the system down.
Only root should be able to do it, and only people with the
appropriate skills should have root access. The same should be
true for physical security, where the key that provides access
to the on/off switch should only be available to those same
people. Clearly your data is considered important, and the
above level of security should be required regardless of the
time it takes to reboot the system.
As to speeding up a reboot, I can think of one obvious thing
which can be done there too. Your specific application should
be the only application which uses the 3 or 4 large HDs. Have a
smaller disk which holds the OS, swap, etc. Then change the
mount proceedure in the boot rc files such that rebooting does
not wait for the large disks to be checked, but continues on
once the smaller disk's partitions are mounted. That can be
done by setting up partitions on the large disks to not be
automounted, and adding a separate command in the rc files to
mount them, but run it in the background so that rebooting does
not wait for it to complete. The application, or whatever
process invokes it, will need to verify that the appropriate
partitions have been mounted before it runs.
