I am looking for an enhancement to multi-thread or parallelize rsync. Are there any plans that would allow one to set a parameter, like 'number_of_threads' and rsync will ship multiple files at the same time?

on Solaris 10 5.10 Generic_118822-23 sun4v sparc SUNW,Sun-Fire-T200 I run #iostat -xn 5 to monitor the IO statistics on SF T2000 server. The system also have a heavy IO load, for some reason iostat donot refresh (no any update). It seems like iostat is calling pause() and stucked there. Also my HBA driver''s interrupt stack trace indicates there is a lot of swtch(), the overall IOPS

Dtrace and Performance Teams, I have the following IO Performance Specific Questions (and I''m already savy with the lockstat and pre-dtrace utilities for performance analysis.. but in need of details regarding specifying IO bottlenecks @ the controller or IO bus..) : **Q.A*> Determining IO Saturation bottlenecks ( */.. beyond service times and kernel contention.. )/ I''m

Hi ! I am using MPXIO for doing multipathing across four HBA''s. Now I need to know how much IO/sec each HBA card is serving. With EMC powerpath installed, we could get this using powermt display every=5. is there any way I can use Dtrace to extract this output ? I guess MPXIO just shows one Device name to the OS so dev__pathname won''t be able to tell me per HBA i/O. Regds,

In order to get more information on IO performance problems I created the script below: #!/usr/sbin/dtrace -s #pragma D option flowindent syscall::*write*:entry /pid == $1 && guard++ == 0/ { self -> ts = timestamp; self->traceme = 1; printf("fd: %d", arg0); } fbt::: /self->traceme/ { /* elapsd =timestamp - self -> ts; printf("

Greetings, We''re trying out a new JBOD here. Multipath (mpxio) is not working, and we could use some feedback and/or troubleshooting advice. The OS is oi151a7, running on an existing server with a 54TB pool of internal drives. I believe the server hardware is not relevant to the JBOD issue, although the internal drives do appear to the OS with multipath device names (despite the fact

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Good day all, I am running CIFS/9000 (which is based on Samba 3.0.22 with, I'm guessing, security and serious bug fixes through 3.0.25 -- it's not all that clear), and running all of this on an HP-UX 11.11 PA-RISC server. The problem I have is when I do a right-click on a mapped printer and ask for the properties, my connected daemon

We had problem using tagged vlans inside domU. Testing shows that this is caused by changing network interfaces in network-bridge script. Following patch should allow to use vlans in guest. Testing scenario: configure vlan network (e.g. vlan 1 on eth0 => eth0.1) start xend create domU and configure same vlan inside it You can see that vlan is still <interface>.<vlan_id>. You can

Hello, with OpenSSH_2.3.0p1 running in HP-UX 11.00 I noticed that the "SD commands" (like "swcopy") produce the following error when being logged in via SSH: ERROR: RPC exception: "Who are you failed (dce / rpc)" 11/29/00 11:20:18 MET Ideas? Regards, Ulrich P.S. Not subscribed to the list

Hi All, Is there a way to tune the zfs prefetch on a per pool basis? I have a customer that is seeing slow performance on a pool the contains multiple tablespaces from an Oracle database, looking at the LUNs associated to that pool they are constantly at 80% - 100% busy. Looking at the output from arcstat for the miss % on data, prefetch and metadata we are getting around 5 - 10 % on data,

Hi!We''re trying to pinpoint our performance issues and we could use all the help to community can provide. We''re running the latest version of Nexenta on a pretty powerful machine (4x Xeon 7550, 256GB RAM, 12x 100GB Samsung SSDs for the cache, 50GB Samsung SSD for the ZIL, 10GbE on a dedicated switch, 11x pairs of 15K HDDs for the pool). We''re connecting a single Linux

Hi, I am adding DTrace probes within NFS v3 client. In my current implementation, I use some tsd_*() functions and kmem_zalloc() function. These functions might be heavy and affect the performance. I want to call this function only when DTrace is running or the DTrace probes are enable. So is there a way to check DTrace is running or DTrace probe is enabled? Regards, Danhua

Hi All, Can I get Dtrace command, which is useful for regular system administration like performance issue. Advance Thanks Muthu -- This message posted from opensolaris.org

Hi Expert I want to use dtrace to monitor the content change of one file. I made following scripts, #!/usr/sbin/dtrace -s inline int MYPID = $1; syscall::write:entry /pid == MYPID/ { tracemem(arg1, arg2); printf("\n"); } It always has an following error bash-3.00$ sudo dumpFIFO.dtrace 3836 dtrace: failed to compile script ./dumpFIFO.dtrace: line 19: tracemem( ) argument #2

I have found that pid provider can not create memcpy:return probe for 64bit process on snv_110. For example, the pid is 10603, I will have following output for dtrace command: #dtrace -n pid10603:libc.so.1:memcpy:return dtrace: invalid probe specifier pid10603:libc.so.1:memcpy:return: probe description pid10603:libc.so.1:memcpy:return does not match any probes This just

I have a number of systems running solaris10 and i see the package and binary for dtrace installed however whenever we try to run anything we get this error dtrace: failed to initialize dtrace: DTrace device not available on system the only system in which i dont have this error is the development server that has the full solaris 10 install while others are minimized, do i need additional

All, With Jon Haslam''s exciting news about the DTrace doc wiki (if you haven''t seen it yet, make your way to http://wikis.sun.com/display/DTrace), and with some of the discussion with the Apple folks, I''m wondering if the time isn''t right for something of a DTrace summit, perhaps as an unconference. The idea here would not be a DTrace user group (though that

Hi All, Is there a simple way to list all currently open file descriptors ? TIA.. Regards, Venkat -- This message posted from opensolaris.org

Hi, all, I''m a newbie on dtrace and the problem I am having is: For processes which have been running for more than a couple of hours, dtrace doesn''t seem to be able to trace(I waited for at least one hour and didn''t see anything happening). However, it works every time for a relatively new process. Any insight or help will be appreciated. This is my machine:
