Citrix 6.2SP1 - snapshot error - unpause operation
Hello,
Is anyone using Citrix'a 6.2SP1 noticed a problem with blocking the VDI
during making snapshot'a?
VDI disk during snapshot is marked as paused and virtual machine can not
use it.
It looks like the process tapdisk (mapping VDI disk to the virtual machine)
was destroyed and at this point the system/hypervizor can not perform the
operation 'unpause'.
We reported the matter to the Citrix forum but topic is dead :-(
Details can be found under the link:
http://discussions.citrix.com/topic/350486-snapshot-error-unpause-operation/#
entry1812789
If anyone would have any tips would be grateful.

Hello,
recently again the situation is repeated. These errors themselves ...
We have added a tap-ctl to monitoring as suggested by Radek.
We have the following observations:
- one of the disks has changed status
pid = 19919 minor = 16, state = 0
args=vhd:/dev/VG_XenStorage-6df30603-5815-133c-4218-3d49cfca0561/VHD-88291650-4138-403d-9263-973343891a78
pid = 19919 minor = 16, state = 0x2a
args=vhd:/dev/VG_XenStorage-6df30603-5815-133c-4218-3d49cfca0561/VHD-88291650-4138-403d-9263-973343891a78
- two other drives has disappeared and tap-ctl does not show them any more.
Is there anyone able to interpret these behaviors when performing a
snapshot?

Tomku, try to run "tap-ctl list" command before you do the snapshot and when it gets stuck.
What's the difference?
You should see your VDI open and probbaly paused for some short time but it should return to normal state after max few seconds.
Radek.

Tomku, try to run "tap-ctl list" command before you do the snapshot and when it gets stuck.

You should see your VDI open and probbaly paused for some short time but it should return to normal state after max few seconds.
