Is it possible to use DTrace to display the number of arguments and their types for userland or kernel functions that are not explicitly instrumented or documented by their authors? We''re talking about functions provided by Veritas VxVM/VxFS and the like, and for example, we might want to try tracing I/Os from App => VxFS => VxVM => ssd driver to see where I/Os get aggregated or

...e how the tags are stored, I see that the tables tags & taggable are empty. Yet, the query from w/in the tests seem to return correct results. Is there a caching issue using mysql (v 5.0.26) on Mac OSX? If so, how can I flush the cache? The mysql doc seems to indicate that it uses a special fctl method to flush automatically.

I have two computers: a Linux box which I use as my workstation (day-to-day use) and an OpenBSD box which I designate for server tasks: gateway, firewall, etc. I use rsync to mirror many gigs worth of data from the Linux box (running rsync in daemon mode) to the OpenBSD machine (running an rsync client job nightly). Since the amount of data and the number of files that I mirror is great, most of

We have a 32 GB RAM server running about 14 zones. There are multiple databases, application servers, web servers, and ftp servers running in the various zones.

I have just recently (physically) moved a system with 16 hard drives (for the array) and 1 OS drive; and in doing so, I needed to pull out the 16 drives so that it would be light enough for me to lift. When I plugged the drives back in, initially, it went into a panic-reboot loop. After doing some digging, I deleted the file /etc/zfs/zpool.cache. When I try to import the pool using the zpool

Hi i''m trying to write my first dtrace script apparently i bit off a bit more than i can chew, i want to track io over sockets, i found your socketsize.d that gave me how to track writes, but i''m at a loss how to track reads, frankly i don''t see how your write tracker works because it uses a probe in a function that only takes two arguments but you grab size of write
