Subject: Optimal Linux RAID Support? Questions.
Date: Tue, 31 Aug 1999 10:46:55 GMT
Hello, I am in the process of configuring and setting up some Linux
servers for my company, two of which will have their own RAID (~50gb and
~250gb respectively). I have been using only SCSI devices for years but
the new EIDE (e.g., Ultra ATA/66) drives/cards look acceptable and given
its drastic cost difference, it seems like a very attractive option for
RAID structures. SCSI is out of the question due to cost, so I will be
using Ultra ATA/66 drives.
The two servers that I will be putting a RAID into have two different
uses, the 50gb one is used for the main fileserver and thus needs
redundancy (RAID 5), the 250gb one will only be used as a temporary
storage RAID and redundancy is not important (RAID 0), except maybe to
keep the RAID functional if a drive goes down, but no backups will be
kept and data being lost is not a concern so getting more space out if
this RAID is more important.
The question is this... software or hardware based RAID? And what
are the hardware requirements?
Hardware - I have heard that the FastTrak66 card is good, however it
has a 4 drive limitation (and im not sure of the throughput of 4
drives would be any higher than 2), so I cant use it for the large RAID
(at least not as a stand alone device), and apparently has no support
for RAID 5 which is what i'd like to use for at least the main file
server. Is this the only option for an EIDE hardware based RAID
controller?
Software: I am not sure how much the EIDE bus issues have changed, I
know the drive being used still needs to take control of the bus, but
are the latency issues in switching between two drives on the same bus
as bad as it used to be? Would getting multiple EIDE cards/busses, one
for each drive so it has its own dedicated bus, create a significant
performance boost with software RAID? For example, I could get 4
dual-EIDE bus cards and have a total of 8 disks. How about the
Linux EIDE controller drivers what kind of load will that create? Which
chipset is best? What kind of system will I need to be able to manage
this RAID and the 100base network mounts using it? I dont plan on using
the fileservers for anything other than the RAID, servicing the network
mounts and backup (only on the main server).
I dont have the money to just buy all the drives I need and various
cards and benchmarking the various configurations (and have not yet
found anyone or site that has), also what drives I get depends on the
card/configuration.
Ultimately i'd like to get the most throughput as possible while
keeping the cost down. However I am unclear on the performance details
regarding EIDE and Linux RAID. If anyone could help out that would be
greatly appreciated!
Thanks!

I think you use the "mt" command to enable hardware
compression before running tar.

Hi. I got my settings like you did, but I ran sndconfig --noautoconfig

I don't want the compression on all the time.
Mine has a jumper that turns the compression on or off. The manual
also says that issuing the proper mode select command over the scsi
bus will turn the compression on or off regardless of the jumper
setting.

2.2.11 does have a "nasty" memory leak in some configurations,
but this is supposed to have been fixed in 2.2.12. Are you sure
it's the kernel that's responsible?

Subject: Kernel panic 'skput over,' 2.2.12
Date: 31 Aug 1999 07:14:54 -0400
Having some problems with a 2.2.12 kernel I've built in the last few days.
Last night it kernel paniced for the second time in 12 hours. The first
panic, I could not see the msg as it scrolled off the screen trailing some
garbage. The second one was sitting at the console when I came in this AM:
Kernel panic: skput: over: c01b2c0d: 287 put: 287 dev: eth0
In swapper task- not syncing
I looked up the address in my System.map file and it lists 't
boomerang_rx' at addr c01b29cc, 't vortex_close' at c01b2dac. This machine
has two 3Com 3C905-TX ethernet cards, both running at 100Mbit/sec.
This box acts as a gateway between our two IP subnets and runs a sendmail
server for aliasing/queueing. Yesterday's panic happened under semi-major
load (multi-node pc backup across the subnets). Last night, the load
should have been relatively light.. 2-3 users and perhaps some Quake2
traffic. Other box particulars are:
AMD K5/133 (believe that's the right speed)
Generic Intel PCISet motherboard (circa '95)
64Mb RAM
kernel compiled with gcc2.7.2.3
Slackware v4.0 dist.
Vortex drivers are NOT modules
Compiled with 'optimize as router not host'
No firewalling/masquerade stuff compiled in.
I've backed off to my last working kernel (2.2.11) for now, which I know is
supposed to have some problems in the TCP/IP stack. What's the last known
GOOD stable 2.2.x kernel? (didn't 2.0.(8 || 10) have some stability problems
too?)
Let me know if I can offer any other info. Thanks for any help.

ASF is a proprietary Microsoft format. Until somebody reverse

try wether id's and termination is ok. adaptec controllers are known for
their erratic behaviour with poor or incorrect termination.
als see weter there is no fork construction in the cable (eg: both wide and
narrow connectors on controller used internally and extetrnal devices
present. If there are devices on both the internal connectors, then disable
low-termination.
maybe faulty cabling is the cause.... try replacing the cable.
most of my scsi trobles are one of these.
als disable scan (scsi config automagically) as this protocol leads to
trouble also. just be shure that only the devices at cable ends are
terminated.

Oh brother. Same happened here. But What causes me concern is that as
more companies start "packaging" Linux it will become more difficult to
port these freebie apps like RealAudio and so on.
Now IBM is going to start working with Red Hat and personally after
seeing the way they've botched OS/2 for end users I'm not real happy
about that.

I've had problems with memory timing in a K6-233Mhz (32 meg 60ns and 65
mes 50ns). As soon I removed the older, slower memory (I've kept only 64
megs) the problem disapeared. But in my case i had no freezes, but sig

Check your box to make sure its well refrigerated. Sometimes a defective
or suddimensioned cooler may cause the CPU to overheat.

Hello All,
I have a portability question:
On Solaris, the waitpid syscall has as a WNOWAIT
option (in addition to WUNTRACED and WNOHANG): the
waitpid syscall keeps the child in a waitable state, so
the same child may be waited for once more. On Linux
the waitpid syscall misses this option. Does anyone know
