Hey all,
I am sort of at a loss at the moment, and I was hoping that someone might be
able to shed some light on things. I am new to the concept of AOE, so please
bear with me.
# uname -a
Linux springfield.umtri.private 2.6.26-2-sparc64-smp #1 SMP Tue Jan 12 23:43:53
UTC 2010 sparc64 GNU/Linux
So here is the setup
I have a SunFire 280R connected to two SCSI StorEdge a1000's. The two a1000's
are bundled together with LVM, and I created a 5 GB partition (ext3) on them to
test with. I "export" that partition using the following.
# vbladed 0 0 eth0 /dev/virt-vol/dom0
which works fine, my client (CentOS 5.4) is able to see the partition and mount
it. However when I try to write to e0.0 from the client I get the following in
my server logs:
Feb 18 09:44:32 vmdisk kernel: [ 3072.474371] aoe: AoE v74 initialised.
<--- modprobe aoe
Feb 18 09:45:56 vmdisk vbladed: pid 8275: e0.0, 10485760 sectors O_RDWR <---

Feb 18 09:47:37 vmdisk kernel: [ 3257.653765] strbuf_flush: ctx flush timeout

matchreg[8000000000000001] ctx[4d]
Some writes to e0.0 do work. but they are rather slow. I tried doing an rsync
-av /usr /mnt/e0.0 and it got stuck in the middle somewhere, I killed the rsync
and
saw those types of message on the server (strbuf_flush....) continue to fill
up the server log for over an hour.
Any ideas?
Thanks,
Nathaniel
