similar to: Dtrace provider for the COMSTAR iscsi Target Port Provider - Review Request

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. thanks Priya -------- Original Message -------- Subject: Dtrace provider for the COMSTAR iscsi Target Port Provider - Review Request Date: Thu, 23 Apr

I have added a specification of probes for the fibre channel COMSTAR port provider to the DTrace section of wikis.sun.com. The proposal may be found here: http://wikis.sun.com/display/DTrace/fibre+channel+Provider I welcome feedback regarding this proposal. Thanks, Sam

I would like to request approval of the the DTrace proposal for the COMSTAR iSCSI target port provider. I have updated the specification of the iscsi provider at http://wikis.sun.com/display/DTrace/iscsi+Provider. Your feedback is appreciated. thanks Priya -------------- next part -------------- An embedded and charset-unspecified text was scrubbed... Name: iscsit_dtrace_draftv8.txt URL:

Hi all, again might be a FAQ, but imagine that I have a pool on USB stick, I insert the stick, and how can I figure out what poools are available for ''zpool import'' without knowing their name? zpool list does not seem to be listing those, thanx, Martin

The page describing setting up HVM domains[1] contains an incorrect link for downloading qemu-img. It has a link to http://dlc.sun.com/osol/xen/download/current/qemu-img while it should be http://dlc.sun.com/osol/xen/downloads/current/qemu-img (note the ''s'' on downloads).

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

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 naa.600144f030bc450000004a9806980003. Path vmhba33:C0:T0:L0 is

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

Hi Priya, You did not follow the logic of the pseudo-code. The sink("filename"), sink() pair captures whatever output is generated between the first sink statement and the second sink statement. You need (possibly) to do: sink("C://Users//Priya//Desktop//Attractor analysis_all genes//synaptogenesis//attr.txt") net <- loadNetwork("C://Users//Priya//Desktop//Attractor

Let's try a simple example. > # Create a script file of commands > # Note we must print the results of quantile explicitly > cat("x <- rnorm(50)\nprint(quantile(x))\nstem(x)\n", file="Test.R") > > # Test it by running it to the console > source("Test.R") 0% 25% 50% 75% 100% -2.4736219 -0.7915433

Hi Eric,Thanks for the explanation. Is there a way to save the results automatically after the analysis gets over?. As I recently lost the results, because I didn't save the results. I don't want to run the sink or save command after the analysis is over rather run the command for saving the file before starting to run the analysis, so the file gets saved automatically after the script has

Hi David,Thank you for the example.When I try to use the cat function, I get an error cat(attr<-getAttractors(net, type="asynchronous"))Error in cat(attr <- getAttractors(net, type = "asynchronous")) : argument 1 (type 'pairlist') cannot be handled by 'cat' Please let me know, if I have used the function in right way?. Thank you Priya ?

Hi Eric,I tried as you suggested but I could not find the output in the text file I created (attr.txt) net <- loadNetwork("C://Users//Priya//Desktop//Attractor analysis_all genes//synaptogenesis//regulationof_dopamine_signaling_submodule3.txt")sink("C://Users//Priya//Desktop//Attractor analysis_all genes//synaptogenesis//attr.txt") sink() attr <- getAttractors(net,

I want to list/use the nfs probes but I get the error "dtrace: failed to match nfs*:::: No probe matches description". Is there a way to enable nfs provider probes? My system is running snv_112 (bfu''ed from the gate archive) # dtrace -lP nfs* ID PROVIDER MODULE FUNCTION NAME dtrace: failed to match nfs*:::: No probe matches

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

Some comments: 1. sink() does not return a value. There is on point to set attr <- sink(...). Just give the command sink("C://....etc") 2. to complete the saving to the file you must give a second sink command with no argument: sink() So your code would be (pseudo-code, not actual code) sink( "filename" ) do something that prints output which will be captured by sink

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, Bruno -------------- next part

Hi, Nexenta CP and NexentaStor has integrated COMSTAR with ZFS, which provides 2-3x performance gain over userland SCSI target daemon. I;ve blogged in more detail at http://www.gulecha.org/2009/03/03/nexenta-iscsi-with-comstarzfs-integration/ Cheers, Anil http://www.gulecha.org

Hi,I want the results to be saved automatically in a output text file after the script has finished running. I used the sink function in the following example, but the results file (output.txt) was empty. net <- loadNetwork("C://Users//Priya//Desktop//Attractor analysis_all genes//synaptogenesis//regulationof_dopamine_signaling_submodule3.txt")# First I loaded theinput file for

Hello, I was doing performance testing, validating zvol performance in particularly, and found that zvol write performance to be slow ~35-44MB/s at 1MB blocksize writes. I then tested the underlying zfs file system with the same test and got 121MB/s. Is there any way to fix this? I really would like to have compatible performance between the zfs filesystem and the zfs zvols. # first test is a
