I can observer similar things from time to time, other commands also
hung like 'zpool status' of 'zfs list', etc. sometimes it takes dozen
minutes sometimes even hours after they complete...

If you can take a crash dump while it is hung and make it available, we can 
take a look.

[zfs-discuss] zfs list hangs if zfs send is killed (leaving zfs receive process)

2007-07-13 Thread David Smith 
I was in the process of doing a large zfs send | zfs receive when I decided 
that I wanted to terminate the the zfs send process. I killed it, but the zfs 
receive doesn't want to die... In the meantime my zfs list command just hangs.

Here is the tail end of the truss output from a truss zfs list:

Let me know if something else is needed to figure out what is going on.

The system is an x4600 running Solaris 10, with a fairly recent patch set.

Well, the zfs receive process finally died, and now my zfs list works just fine.

If there is a better way to capture what is going on, please let me know and I 
can duplicate the hang.
