Description Qunfang Zhang 2010-06-18 10:58:04 UTC

Description of problem:


Version-Release number of selected component (if applicable):
kvm-83-164.el5_5.12

How reproducible:
Always

Steps to Reproduce:
1.create a new qcow2 image (vdisk) on nfs server.
#mount -o soft,timeo=1,retrans=1  10.66.91.195:/home/exports /opt
#qemu-img create -f qcow2 /opt/test.qcow2  10G
2.boot an pre-installed kvm guest with the vdisk attached.
/usr/libexec/qemu-kvm -m 2G -smp 2 -drive file=/opt/RHEL5.5-64-qcow2,media=disk,if=ide,index=0,cache=off,werror=stop  -drive file=/opt/test.qcow2,media=disk,if=ide,index=1,cache=off,werror=stop -net nic,model=rtl8139,vlan=0,macaddr=02:00:40:3F:20:4B -net tap,vlan=0,script=/etc/qemu-ifup -uuid 3bcd5af1-9ca7-4975-a88e-9b1e9d378abc -usbdevice tablet -no-hpet -rtc-td-hack -no-kvm-pit-reinjection -monitor stdio -cpu qemu64,+sse2 -balloon none -startdate now -name 161-rhel5.5 -vnc :10 -boot c -notify all
3.create partition and file system on vdb inside kvm guest
  #fdisk /dev/hdb
  #mkfs.ext3 /dev/hdb1
4.#mount /dev/hdb1 /mnt
5.copy a large file to /mnt directory
  #cp /root/RHEL5.4-Server-20090819.0-x86_64-DVD.iso  /mnt 
6.on the nfs server . stop the service
   #service nfs stop
7.on the kvm host. wait the nfs connection time out.
8. start and  stop nfs server for lots of iterations.

Comment 3 RHEL Program Management 2011-01-11 20:27:29 UTC

This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.

Comment 4 RHEL Program Management 2011-01-11 22:52:04 UTC

This request was erroneously denied for the current release of
Red Hat Enterprise Linux.  The error has been fixed and this
request has been re-proposed for the current release.

Comment 6 Ronen Hod 2011-10-31 07:10:07 UTC

Since we didn't find the capacity to fix it for 5.8, it doesn't make sense to continue dragging it to the next version. Closing.
