Hi,
Now that I've got that 3-day-long, let's-waste-some-time-with-a-
broken-dom0 episode, I can get back to the real problems that are
preventing me from getting any use out of my Xen-based server.
What is happening, basically, is that as soon as some guest
domains get busy, the hard disks go south for the winter.
I know this is not really a Xen issue (at least not directly) but
as the problem only happens in a Xen setup, I thought I'd try to
ask about it here.
The server has four SATA hard disks. It has worked with the same
hardware setup for many months, with processor- and disk-
intensive applications, with no problems. Now, I can start dom0
and guest domains with no problem, and they run fine as long as
they don't try to do a lot. But as soon as they get busy - say,
compiling something - the console shows an endless stream of:
ata1: command 0x35 timeout, stat 0x50 host_stat 0x64
ata2: command 0x25 timeout, stat 0x50 host_stat 0x64
ata4: command 0x35 timeout, stat 0x50 host_stat 0x4
And the system stops responding, until I reset the server or throw
it out the window (well, not yet, but it's coming).
I've seen posts saying that these errors are related to APIC, so
I tried adding "noapic acpi=off" to the dom0 kernel command line.
No change.
If anyone's wondering why ata3 isn't in the list... it's a
different drive - a 250GB WD while 1, 2 and 4 are 400GB Seagates.
Interesting?
Any ideas/suggestions?
Hi,
Are you working with an ICH6 or ICH7 chipset for SATA connections.
If zo. check your BIOS settings (IDE Operation Mode). I've
experienced this before. Somehow the Enhanced Mode setting can
cause troubles. You can have it set to "Enhanced Mode", but need to
make sure only SATA is enabled (not SATA + PATA). After setting
this to SATA, the PATA devices are still accessible and the timeou
problems disappeared for me.
Hope this may help you.
Thanks, Rick, but no luck... my drives are on silicon Image chips,
separate from the IDE controller.
Itai
