[OmniOS-discuss] ZFS Logical Unit stuck in the offlining state with COMSTAR

[Shvayakov A.]

Hi,

I got a problem - ZFS Logical Unit stuck in the offlining state  with COMSTAR

Conditions to reproduce the problem:

You should to create Logical Unit with COMSTAR

stmfadm create-lu /dev/zvol/rdsk/GIGO/zvol200g
stmfadm add-view 600144F054A281000000513DB9770005

Then I mounted this device on the initiator and began to upload data with dd
During copying, I removed the LU

Intense data upload is a prerequisite for the reproducing of problem

stmfadm delete-lu -k 600144F054A281000000513DB9770005

Logical Unit  stuck in the offlining state

stmfadm list-lu -v
LU Name: 600144F054A281000000513DB9770005

     Operational Status: Offlining
     Provider Name     : sbd
     Alias             : /dev/zvol/rdsk/GIGO/zvol200g
     View Entry Count  : 0
     Data File         : /dev/zvol/rdsk/GIGO/zvol200g
     Meta File         : not set
     Size              : 214748364800
     Block Size        : 512
     Management URL    : not set
     Vendor ID         : SUN
     Product ID        : COMSTAR
     Serial Num        : not set
     Write Protect     : Disabled
     Writeback Cache   : Enabled
     Access State      : Active

As a consequence, it cannot be unloaded from the COMSTAR framework

stmfadm delete-lu 600144F054A281000000513DB9770005
stmfadm: resource busy

Hence the GIGO pool cannot be exported:

zpool export GIGO
cannot export 'GIGO': pool is busy

Resulting in the RSF-1 cluster aborting failover

Now only  reboot...

This bug is present in OpenIndiana too. I tested it.
Support RSF-1 says that this problem is fixed in the Nexentastor
What do you know about it?
Can you fix this bug in OmniOS?

Best regards,
