Hi,
I have a Debian jessie server with an LSI SAS controller using the
mpt3sas driver.
Under the Debian jessie amd64 kernel (linux-image-3.16.0-4-amd64
3.16.36-1+deb8u2) running under Xen, I cannot put the system's
storage under heavy load without receiving a bunch of "swiotlb
buffer is full" kernel error messages and severely degraded
performance. Sometimes the system panics and reboots itself.
These problems do not happen if booting the kernel on bare metal.
With a bit of searching I found someone having a similar issue with
the Debian jessie kernel (though 686 and several versions back) and
the tg3 driver:
https://lists.debian.org/debian-kernel/2015/05/msg00307.html
They mention that suggestions on this list led them to compile a
kernel with NEED_DMA_MAP_STATE set.
I already seem to have that set:
$ grep NEED_DMA /boot/config-3.16.0-4-amd64
CONFIG_NEED_DMA_MAP_STATE=y
Is there something similar that I could try?
The machine has two SSDs in an md RAID-10 and two spinning disks in
another RAID-10. I can induce the situation within a few seconds by
telling mdadm to check both of those arrays at the same time. i.e.:
# /usr/share/mdadm/checkarray /dev/md4 # Spinny disks
# /usr/share/mdadm/checkarray /dev/md5 # SSDs
I expect to see 200,000K/sec (my set maximum) checking rate reported
in /proc/mdstat for md5, and about 98,000K/sec for md4. This happens
on bare metal.
Under Xen, it starts off well but then the kernel errors appear
within a few seconds; md4's speed drops to ~90,000K/sec and md5's
drops right down to just ~100K/sec. If the machine doesn't do a
kernel panic and reset itself very soon, it becomes unusably slow
anyway.
I can also trigger it with fio if I run jobs against filesystems on
both arrays at once.
Some logs appended at the end of this email.
Would it be useful for me to show you a "dmesg" and "xl dmesg"?
Shall I try a kernel and/or hypervisor from testing?
Thanks,
Andy
