Re: [OmniOS-discuss] possible bug

[Dan McDonald]

Which OmniOS are you running?  Cat /etc/release and look at uname -v. Let's 
first make sure you're up to date.

Also, when it hangs, take a kernel dump  -  "reboot -d" and share the system 
dump.

Thanks,
Dan

[OmniOS-discuss] possible bug

[Hildebrandt, Bill]

Over the past few weeks, I have had 3 separate occurrences where my 
OmniOS/Napp-it NAS stops responding to NFS and CIFS.  The first time was during 
the week of the ZFS corruption bug announcement.  The system and it's 
replicated storage were both scrubbed and zdb analyzed, and nothing looked 
wrong.  I rebuilt the NAS from scratch with updated patches and imported the 
pool.  Same thing happened three days later, and now today, eight days later.  
Each time, a reboot is performed to bring it back.  All services appear to be 
running.  The odd thing is that an "ls -l" hangs on every mountpoint.  Has 
anyone heard of this issue?  Since I am not OmniOS savvy, is there anything I 
can capture while in that state that could help debug it?

Thanks,
Bill

Re: [OmniOS-discuss] possible bug

[Schweiss, Chip]

I've seen issues like this when you run out of NFS locks.   NFSv3 in
Illumos is really slow at releasing locks.

On all my NFS servers I do:

sharectl set -p lockd_listen_backlog=256 nfs
sharectl set -p lockd_servers=2048 nfs

Everywhere I can, I use NFSv4 instead of v3.   It handles lock much better.
