kernel: blk_cloned_rq_check_limits: over max segments limit., Device Mapper Multipath, iBFT, iSCSI COMSTAR
Hi,
WARNING: Long post ahead
I have an issue when starting multipathd. The kernel complains about "blk_cloned_rq_check_limits:
over max segments limit".
The server in question is configured for KVM hosting. It boots via iBFT to an iSCSI volume. Target
is COMSTAR and underlying that is a ZFS volume (100GB). The server also has two infiniband cards
providing four (4) more paths over SRP

Comstar and ESXi
Hello all,
I am running an OpenSolaris server running 06/09. I installed comstar and enabled it. I have an ESXi 4.0 server connecting to Comstar via iscsi on its own switch. (There are two esxi servers), both of which do this regardless of whether one is on or off. The error I see is on esxi "Lost connectivity to storage device

Upgrading a volume from iscsitgt to COMSTAR
Hi, I have a zfs volume that''s exported via iscsi for my wife''s Mac to
use for Time Machine.
I''ve just built a new machine to house my "big" pool, and installed
build 129 on it. I''d like to start using COMSTAR for exporting the
iscsi targets, rather than the older iscsi infrastructure.
I''ve seen quite a few tutorials on how to use

Making a zvol unavailable to iSCSI trips up ZFS
I''ve been experimenting with a two system setup in snv_134 where each
system exports a zvol via COMSTAR iSCSI. One system imports both its
own zvol and the one from the other system and puts them together in
a ZFS mirror.
I manually faulted the zvol on one system by physically removing some
drives. What I expect to happen is that ZFS will fault the zvol pool
and the iSCSI stack will

COMSTAR iscsi DTrace Probes -
The earlier post with the Dtrace probes definition (sent on April 23) was only to solicit feedback from all prospective users of iSCSI DTrace probes. I will follow up shortly with an updated document requesting approval from the community.

Ubuntu iSCSI install to COMSTAR zfs volume Howto
I apologize if this has been covered before. I have not seen a blow-by-blow installation guide for Ubuntu onto an iSCSI target.
The install guides I have seen assume that you can make a target visible to all, which is a problem if you want multiple iSCSI installations on the same COMSTAR target. During install Ubuntu generates three random initiators and you have to deal with them to get things

Migrating ZFS/data pool to new pool on the same system
Can anyone confirm my action plan is the proper way to do this? The reason I''m doing this is I want to create 2xraidz2 pools instead of expanding my current 2xraidz1 pool. So I''ll create a 1xraidz2 vdev, migrate my current 2xraidz1 pool over, destroy that pool and then add it as a 1xraidz2 vdev to the new pool.
I''m running b130, sharing both with CIFS and ISCSI (not

dedicated ZIL/L2ARC
We are looking into the possibility of adding a dedicated ZIL and/or L2ARC devices to our pool. We are looking into getting 4 ? 32GB Intel X25-E SSD drives. Would this be a good solution to slow write speeds? We are currently sharing out different slices of the pool to windows servers using comstar and fibrechannel. We are currently getting around 300MB/sec performance with 70-100% disk busy.

(preview) Whitepaper - ZFS Pools Explained - feedback welcome
Hello list,
while following this list for more then 1 year, I feel that this list was a great way to get insights into ZFS. Thank you all for contributing.
Over the last month''s I was writing a little "whitepaper" trying to consolidate the knowledge collected here. It has now reached a "beta" state and I would like to share the result with you. I call it

Resizing ZFS block devices and sbdadm
sbdadm can be used with a regular ZFS file or a ZFS block device.
Is there an advatage to using a ZFS block device and exporting it to comstar via sbdadm as opposed to using a file and exporting it? (e.g. performance or manageability?)
Also- let''s say you have a 5G block device called pool/test
You can resize it by doing:
zfs set volsize=10G pool/test
However if the device was already

opensolaris COMSTAR io stats
Hi all,
Using "old" way of sharing volumes over iscsi in zfs (zfs set
shareiscsi=on) i can see i/o stats per iscsi volume running a command
iscsitadm show stats -I 1 volume.
However i couldn''t find something similar in new framework,comstar.
Probably i''m missing something, so if anyone has some tips please share
it :)
Thanks in advance,

[LLVMdev] successfully bootstraped on a i686-linux-gnu
Hi,
I recently bootstrapped gcc4 frontend on a i686-linux-gnu too.
As I notice, if the llvm "tools-only " was build with srcdir != objdir ,
the building of llvm-gcc4-1.7.source encountered mistakes of unable to find some header files.
So I just edited llvm-gcc4-1.7.source/gcc/Makefile.in and a line like this:
INCLUDES += -I$(LLVMOBJDIR)/include
With this change, the building errors
