I am having a hard-time reproducing this. I made six LV's:
[root@tst011 ~]# lvs
LV VG Attr LSize Origin Snap% Move Log
Copy% Convert
LogVol00 VolGroup00 -wi-ao 17.56G
LogVol01 VolGroup00 -wi-ao 5.81G
data-1.ext3 XenGroup -wi-ao 10.00G
data-2.ext3 XenGroup owi-ao 10.00G
data-2.ext3-snapshot XenGroup swi-a- 1.00G data-2.ext3 2.41
data-3.ext3 XenGroup -wi-a- 10.00G
scratch-1.ext3 XenGroup -wi-ao 10.00G
scratch-2.ext3 XenGroup -wi-ao 10.00G
scratch-3.ext3 XenGroup -wi-a- 10.00G
[root@tst011 ~]#
Where each scratch-X/data-X was prepared with 'mkfs.ext3'
And ran two guests, where each guest configuration looks as so:
kernel="/mnt/lab/latest/vmlinuz"
ramdisk="/mnt/lab/latest/initramfs.cpio.gz"
extra="console=hvc0 debug"
memory=768
vcpus=4
on_crash="preserve"
#vif = [ 'mac=00:0f:4b:00:00:68, bridge=switch' ]
vfb = [ 'vnc=1, vnclisten=0.0.0.0,vncunused=1']
disk = [ 'phy:/dev/XenGroup/scratch-1.ext3,xvda,w',
'phy:/dev/XenGroup/data-1.ext3,xvdb,w']
(the other is using -2 obviously).
And each guest is running 'mount /dev/xvda /mnt-1;(cd /mnt-1;fio
iometer-file-access-server)'
to produce I/Os on the xvdb/xvda disks.
As those guests are chugging along, I ran your script with:
root 6250 4438 0 10:12 pts/4 00:00:00 /bin/sh ./lvm-test.sh loop 100
1G 5
(I tried 100 1G 0)
and so far it is running.... how long should I wait until I hit this problem?
This is on CentOS 5.5 and also on Fedora Core 13. Dom0 and DomU are all x86_64.
Dom0 is:
commit 892d2f052e979cf1916647c752b94cf62ec1c6dc
Merge: 35e2e28... 376faec...
Author: Jeremy Fitzhardinge <jeremy.fitzhardinge@xxxxxxxxxx>
Date: Fri Feb 11 13:31:03 2011 -0800
Merge commit 'v2.6.32.28' into xen/next-2.6.32
(plus one patch I just posted - but that is to fix the serial console, so
it is not relevant to this problem).
DomU is 2.6.38 kernel, but I can swap over to the same as Dom0..
Attached is the script I am using.
