[smartmontools-support]system/io performance is unbearably bad during long selftest

[David M. <ce...@dm...>]

Hi,

I have one system out of about 20 here that basically 'goes away' during 
the selftest of the drives.  In fact, I/O can be delayed by MINUTES 
during the long selftest.   It does always complete, however, if you are 
patient enough.

I have remote monitoring of the machine, and every time the long 
selftest fires off (Sunday Night/Monday morning) all kinds of 'failures' 
are reported because the services cannot respond in a reasonable time.

System is Centos 4.2.  The IDE interface is amd74xx.  The drives are 
Seagate ST380011A.

Each drive is on it's own channel.

Any ideas?


Thanks,
David
