Hi,
i would like to comment congelation system during massive write to disk. There is my testing environment:

HW:
AMD Opteron 1212 2.0GHz 2Core
4GB RAM
MB Supermicro H8SSL-i2
4 x WD 2500YS-01SHB0 RE16
Adaptec AAR-2420SA

SW:
Lenny with proxmox-ve-2.6.32
Code: 
Linux version 2.6.32-1-pve (root@oahu) (gcc version 4.3.2 (Debian 4.3.2-1.1) ) #1 SMP Fri Jan 15 11:37:39 CET 2010 ()

My test procedures:
1. FTP upload big file (4GB disk image) over 1GB LAN
(approx. first 100MB uploaded only)
2. postmark
postmark settings:
Code: 
set number 60000
set transactions 100000
set size 500 153600
set read 4096
set write 4096
set subdirectories 150
When I install proxmox-ve-2.6.18 both procedures run OK.

can you test the 2.6.32 kernel from the pvetest repository?
 
Unfortunately, bad things happened...
after huge of testing:
Code: 
# less /var/log/kern.log
-bash: /usr/bin/less: Input/output error
# dmesg 
-bash: /bin/dmesg: Input/output error
on the console:
Code: 
aacraid: Host adapter abort request (0,0,6,0)
aacraid: Host adapter reset request. SCSI hang ?

I must say that this error occurred after load module w83793 for lm-sensors... :(
Without him seems to be everything all right.
All previous tests (on the kernel 2.6.18.2 and 2.6.32.1) has been done without w83793 module.
