[sheepdog-users] Storage loss due to error

[Vedvyas shanbhogue]

Running a stress test where I have a VDI conneted over ISCSI. I have a
script on the client that copies a 4G .iso file to a new folder in the VDI
and then runs a SHA1 check on the copied .iso and then deletes the .iso.
After a few iterations of this script I sometimes see the storage is lost -
the client times out and aborts. In sheepdog logs I see following messages.
Any suggestions/hints on debugging this failure?
