John,

I'm not aware whether or not your question has been answered. If not,
please send output of `pciconf -lv'.

It was a hardware problem - nothing that a new motherboard couldn't fix.

Can you give us the output from "dmesg" after a verbose boot, and also 
the output of "pciconf -l"?  Are the network interfaces on board, or 
on a separate card?


Gavin


Doh!

Turns out to be a hardware problem - when checking the jumpers I 
discovered a transistor on the MB next to the failed nic that is too hot 
to touch - new MB is on the way from Silicon Mechanics (who by the way 
are great to deal with)


With hardware today I see so few dead components that I stopped checking 
the obvious first.

It's a home server and the storage is near-line photo archives (I'm a
professional photographer) that's also backed up on REV cartridges.  I
don't need the performance of a multi thousand dollar server box just
the storage capacity to host up to a terabyte of images.  If I really
needed the performace I'd build somthing with SCSI or SATA drives but I
just need capacity.

Currently the box has:

IDE 80 GB main disk (root usr var tmp swap )
1x250GB FW 400 - scratch storage
2x300GB FW 400 in a gstripe set - storage for BackupPC which covers the
desktop boxes.
2x500GB FW 800 (on a separate FW800 controller) - this is going to be
the photo archive in a gvinum mirror set.
Then I have 4xUSB250GB drives that are not really doing anyting right
now and I may build into a RAID5 for future expansion.

Up to a point - beware of geom_mirror with USB and FireWire disks - it's
temperamental at best and with my FireWire drives simple won't work
reliably (panic during boot if a rebuild is needed and unrecoverable
errors during rebuilds).  I've just re-done the mirror set on my box
with gvinum and so far it's looking good - it boots ok and rebuild is a
lot faster.

This on a 5-STABLE box with a FW800 card a 2x LaCie 500GB bigger disk
extreme external FW drives.

If this works for my next trick I'll try RAID5 with 4x250gb usb drives.

gmirror rebuild speed limited by value of HZ?

[John Pettitt]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
 

I've noticed that gmirror seems to rebuild disks by copying 128K every
clock tick (or about 12.8 MB/sec on a 100HZ box) - changing HZ to 1000
resulted in my system being limited by the underlying disk controller
speed (~ 30MB/sec between FW800 drives on the same 32 bit controller)
does anybody know if this behavior was intentional ?

Get a copy of memtest86 (see http://www.memtest86.com/ for a bootable
ISO) - it'sd a stand along memory diagnostic that ahppens to put a
reasonable load on the cpu too - with some luck it will show up the
problem and they won't be able to blame BSD (plus it's a good tool to
have anyway).

I'm seeing a similar symptom but only with gstripe and only on usb disks
(the same drives on Firewire work fine) - I can reproduce it (all be it
slowly) by dumping a big file system and restoring it to a gstripe pair
of usb drives - it will will after up to 2 hours.   Unfortunately the
machine is a semi-production server so I have to time my test window - I
have built a DDB/KDB kernel for it and sometime this week I'll try and
get a trace.

USB disk hang - 5.4PRE - gstripe

[John Pettitt]

I just upgraded a box to 5.4PRE and started experiencing regular system
hangs at exactly 1AM - I traced it to BackupPC which was starting it's
run at that time backing up to a gstripe set made from two 300GB USB disks.

The first thing I assumed was that something in Samba or perl didn't
like the 5.4 upgrade so I rebuilt my entire ports tree (portupgrade -fa)
to be sure I had no old libs.  It still fails.

Next I moved the two drives out of their USB housings and put them on
the IDE controller (disconnecting the CD burner to make space).  It's
working fine like that (all be it with disks hanging out the side of the
machine).

So it looks like USB is the culprit.  A few data points:

1) It worked fine on 5.3
2) Motherboard is an Intel D845GVSR with a Celeron D 2.9Ghz and 512Mb Ram
3) USB disk interfaces are from a couple of WD external drives (although
the drives are in fact Maxtor because I upgraded them WD boxes)
4) A single WD250GB disk also on USB seems to work fine  it's only the
stripe set that has a problem
5) When it fails the entire disk system locks (including IDE) but the
machines keeps running until each process locks as it needs to talk to
the disk
6) No meaningful syslog log entries

Any ideas?

Strange lockups - 5.4 PRERELEASE / BackupPC/ Samba3

[John Pettitt]

My home server has been freezing at 1AM every night for the last three
days - this tracks with the upgrade from 5.3 to 5.4 PRE - The only cron
job running at that time is BackupPC which uses samba3 (smbclient)  to
backup windows systems.

Does anybody know of anything in samba3 or perl 5.8 (BackupPC is a set
of perl scripts) that might be causing a lockup.  I've got nothing
unusual in syslog.

Right now I'm rebuilding perl and samba under 5.4 in case there is some
weird library thing between the 5.3 and 5.4 that is causing this - we'll
see tonight if it works.

HZ=1000 has causes a lot of problems for Linux boxes where the system no
longer keeps accurate time because of lost clock interrupts under high
load (video playback seem to be the favorite) - see the ntp lists for
extensive discussion.Is this change really worth the hassle?
