I''m not sure if this is the right place for the question or not, but I''ll throw it out there anyways. Does anyone know, if you create your pool(s) with a system running fishworks, can that pool later be imported by a standard solaris system? IE: If for some reason the head running fishworks were to go away, could I attach the JBOD/disks to a system running snv/mainline solaris/whatever, and import the pool to get at the data? Or is the zfs underneath fishworks proprietar...

How do I query an application to see if it supports any USDT probe points?

Hi, I''m working on some performance analysis with our database and it seems that when the file system (UFS) is mounted with forcedirectio, the IO probe are not triggered when an I/O event occurs. Could you confirm that ? If so, why ? Seb -- This message posted from opensolaris.org

Hi All, I''ve got a problem when I have USDT probes in a static library and in the application code outside of the library. I build the static library containing some USDT probes, glomming everything together (ld -r) before creating the .a file to preserve the probe symbols. This all works fine. I build an application which also has some USDT probes. When I build the application which

This morning we got a fault management message from one of our production servers stating that a fault in one of our pools had been detected and fixed.

Hello, everyone I am a newbie of DTrace and OpenSolaris. Just wondering is it possible to trace every memory read/write of a specific process given the pid? Basically speaking, I want to record the virtual addresses being accessed by the process, using which I will try to do some online analysis. If DTrace does not support this type of instrumentation, will other tools in OpenSolaris help me

This past weekend, but holiday was ruined due to a log device "replacement" gone awry. I posted all about it here: http://jmlittle.blogspot.com/2008/05/problem-with-slogs-how-i-lost.html In a nutshell, an resilver of a single log device with itself, due to the fact one can''t remove a log device from a pool once defined, cause ZFS to fully resilver but then attach the log

Hi all, There''s a dead thread about this back at http://forums.sun.com/thread.jspa?threadID=5075157, but it would be really nice to have support for if/else control flow in actions. Reasons: 1. The ternary operator ?: is already there (though it doesn''t let you do anything with side effects) 2. The user can already write arbitrary and expensive non-cacheable predicates if

Hi, I have used dtrace in the past for diagnosing IO/filesystem related issues. So I am a bit familiar with dtrace scripts Now I want to diagnose performance problems in the java area. May be memory leak etc. The hotspot provider is not present. How can I get them? Does someone have any further advice? regards Hans -- This message posted from opensolaris.org

...e port has been updated in 10.5.3 to fix the issue that caused timer based probes not to fire in the presence of certain untraceable applications. http://blogs.sun.com/ahl/entry/apple_updates_dtrace A big thank you to the folks at Apple for addressing the problem.

Greetings, is there a way to specify probes and other dtrace operations via command line parameters, like " BEGIN { usr_exec=$$1; usr_syscall=$$2; } syscall::usr_syscall:entry /execname == usr_exec && guard++ == 0/ { ... " [this does not work] This would make it possible to create "generic" dtrace scripts. Otherwise, some shellscript with sed-magic would

I''m running OpenSolaris 2008.05 in VirtualBox on a Windows XP host. Playing around with various probes, I found that trying to load any probe associated with bdev_strategy dumps core. I can think of one or two likely and reasonable causes for this, but am assuming it''s undesirable behavior. Anyone know what''s happening here? -- This message posted from

everyone, Just out of curiosity, I did a dtrace -n ''syscall:::entry { @num[execname, probefunc] = count(); }'' and looked at the entries produced by ''rm''. I see everything that rm did, *except* the unlinkat - which is unfortunate because I want to trace which processes have deleted which files. So - does dtrace contain unlinkat as a probe for a system call?

I''d like to prepend TRACE_ to the macro names generated by dtrace -h. For example, change POSTGRESQL_LWLOCK_ACQUIRE(arg0, arg1) to TRACE_POSTGRESQL_LWLOCK_ACQUIRE(arg0, arg1) and still keep postgresql as the provider name. The reason for doing this is to make it clear that the macros are used for (D)tracing. In this particular case, without TRACE_, it appears like the macro is used

Hi: I''m running Indiana (OpenSolaris developer preview) under parallels in OS X 10.5.1. I can consistently get Solaris to hang. Doing a dtrace -n pid\$target::malloc:entry''{@=count()}'' -c ls will consistently hang Solaris. Basically doing anything with PID provider with the -c option seems to hangs Solaris. Only way to recover is to stop and start Parallels desktop.
