Unfortunately not since network interfaces break the Unix "everything is

Maybe ethmX would be even better since regular expressions like "eth.*"
will still match. A lot of tools would have to be changed...

Right. These disks could be doing other stuff instead of reading one
another RAID chunk.

So better always align to stripe size.

I suppose(!) alignment doesn't matter that much (or at all) for RAID10
(which is the right choice for DB loads with only few disks).

But that's just my gut feeling.

If write performance is the bottleneck, you might want to consider an
external file system journal (on SSD, preferably). But I've only
heard/read that it helps and I don't know about MySQL tuning.

Any multiple of your RAID volume's stripe size. What is your RAID
configuration, exactly? IMO, block alignment should only matter for RAID
levels involving checksums.

Re: ordering a T610: what options?

2010-09-30 Thread Tino Schwarze
Hi Louis,

*never* order via online shop. Always get a Dell sales person to talk
to. Just tell them what you want, then let them send you an offer. The
price difference is significant (and the Online configurator IMO has
been sucking for years). A sales rep obviously has access to a lot more
configurations (and the knowledge which one to choose).

To answer one of your questions: You may either just order 8 small disks
from Dell if you don't want to pay their premium prices or you could get
the trays from somewhere else (there are other sources on the net).
Getting empty drive trays from Dell has turned out impossible in the
past.

HTH,

Tino.

Citing this URL:

1.   This issue does not affect any Dell PowerEdge servers shipped
from our factories  and is limited to a small number of the replacement
motherboards only which were sent via Dell’s service and replacement
process for four servers: PowerEdge R310, PowerEdge R410, PowerEdge R510
and PowerEdge T410.  The maximum potential exposure is less than 1% of
these server models.
2.   Dell has removed all impacted motherboards from the service
supply. New shipping replacement stock does not contain the malware.
3.   The W32.Spybot worm was discovered in flash storage on the
motherboard during Dell testing. The malware does not reside in the
firmware.
4.   All industry-standard antivirus programs on the market today
have the ability to identify and prevent the code from infecting the
customer’s operating system. 
5.   Systems running non-Microsoft Windows operating systems cannot
be affected.
6.   Systems with the iDRAC Express or iDRAC Enterprise card
installed cannot be affected. 
7.   Remaining systems can only be exposed if the customer chooses
to run an update to either Unified Server Configurator (USC) or 32-bit
Diagnostics.

Just try it. ;-) It should work since the PERC drivers have been part of
standard Linux kernels for quite some time and GParted is based on
rather recent kernels. The kernel driver will make your LVs appear as
/dev/sda and /dev/sdb, GParted should know about the rest.

Simply power off the machine, pull all disks, insert in desired order.
The controller should pick them up - slot position does not matter since
config is stored on disk.

I'd suggest running rpm --verify -a, then re-installing the affected 
packages. Of course, do 1) backup first, 2) run e2fsck on the partition.
Input/Output error is either a sign of severe filesystem corruption or a
sign of hardware failure - check your logs!

Recue CDs are design to allow fsck ;) - figure out the device, then use
it to run fsck. BE SURE TO HAVE BACKUPS! If the RAID had a problem, both
disks might be broken in different ways - I would not trust that data
without some serious integrity checks or similar.

HTH,

Tino.

Such conversion would be very risky, to say the least. (In RAID1, you
have a copy of each data block on both disks, in RAID0, you distribute
data blocks evenly: block0 -> disk0, block1 -> disk1, block2 -> disk0,
block3 -> disk1 etc.) Apart from that, the SAS 5/iR is a rather stupid
controller with no fancy logic etc, so I guess it's simply not supported.

As far as I know, this is not possible since any RAID setup will need
some bytes of Metadata at the start or end of a partition/device. 

BTW: If the 6i/R is similar to the 5i/R, do not trust it's RAID
capabilities but use software RAID instead. This is just an el-cheapo
RAID controller without any of the advanced features of "real" hardware
RAID. We're suffering from an 5i/R on one of our machines - it's
performance is abysmal.

You don't need to reinstall if you boot from a CD, then setup software
RAID devices on the new disk (with one missing device), copy everything
over, then create the devices on the old disk and let the software RAID
do the sync. If you've got LVM in place, things will get easier.

HTH,

Tino.

Why not just use the MIB files delivered with OMSA? I've got these in an
OMSA 6.1 install:
/opt/dell/srvadmin/sm/mibs/dcstorag.mib
/opt/dell/srvadmin/omsa/mibs/dcs3fru.mib

/opt/dell/srvadmin/etc/srvadmin-isvc/mib/dcs3fru.mib
/opt/dell/srvadmin/etc/srvadmin-storage/dcstorag.mib

Be sure to mail/call your Dell sales rep. I've seen pretty nice
discounts, just by going through the sales rep. You may outsource the
hassle of what exact drive/config to choose to them - just specify your
requirements ("as fast as possible, at least xx GB, ..., for under $6K").

BTW: Don't even consider RAID-5.

Just take out all RAM (and note which DIMM was in which slot), insert
known-good RAM; then have a look at the ESM log. It will tell you where
the errors occured (exact DIMM location). Then move all other RAM in,

I suppose, the only valid answer is: Do your own benchmarks. It depends
on such a lot of factors (data locality, hardware architecture details,
cache coherency, bus contention etc. pp) that you simply cannot predict
how your particular application will perform.

disabling compression for tapes?

2009-12-22 Thread Tino Schwarze
Hi there,

while not totally PowerEdge-related, I suppose, there are enough folks
operating tape equipment under Linux. I've got an LTO-3 autoloader
(Quantum Superloader 3 - there's some Dell-rebranded version of that as
well) and it looks like it has compression enabled and I cannot find a
way to disable it (it's useless - the tapes only get compressed data
anyway).

> mt -f /dev/nst0 datcompression 0
Compression off.

But the web interface still says: Compression enabled. (No tape
currently loaded.) The above mt utility is from cpio-2.6...

Any hints?

Installing the kernel source (whatever that package is named in Ubuntu)
and running "make cloneconfig" should give you a good starting point.
Also have a look at the modules which are currently loaded - you'll
probably won't need a lot more (apart from maybe USB storage support

Looking at /etc/init.d/rc3.d of an 6.1 install here reveals the

dkms_autoinstaller
mptctl
instsvcdrv
dataeng
dsm_om_shrsvc

I've had success with running OMSA manually that way.

Speaking of "gzip" as the limiting factor - I've had success in
replacing gzip by pigz ( http://www.zlib.net/pigz/ ) which makes use of

Yes. First: It's the wrong way around. Second: There is more to Java

I'm running OMSA 6.x on OpenSUSE 11.1 as well and I did not fiddle
anything - just installed the RPMs and they worked.

I wouldn't expect any program to look into /etc/issue at all - it's a
message for users. Maybe you mean /etc/SuSE-release? (Which is the
default one here as well).

HTH,

Tino.
