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

Among other things, I run an http server on my home DSL line (6M/768kbit). The content includes several large image galleries, and when certain crawlers hit our server w/ multiple large image uploads, we end up with large ping time delays - sufficient to disrupt the kids'' on-line gaming. Attempts to control this with robots.txt has not be very successful; Solaris IPQoS appears quite

After the interesting revelations about the X2100 and it''s hot-swap abilities, what are the abilities of the X2200-M2''s disk subsystem, and is ZFS going to tickle any wierdness out of them? -brian -- "The reason I don''t use Gnome: every single other window manager I know of is very powerfully extensible, where you can switch actions to different mouse buttons.

Given a 1.6TB ZFS Z-Raid consisting 6 disks: And a system that does an extreme amount of small /(<20K) /random reads /(more than twice as many reads as writes) / 1) What performance gains, if any does Z-Raid offer over other RAID or Large filesystem configurations? 2) What is any hindrance is Z-Raid to this configuration, given the complete randomness and size of these accesses?

Hello, was use several cad applications and with one of those we have problems using zfs. OS and hardware is SunOS 5.10 Generic_118855-36, Fire X4200, the cad application is catia v4. There are several configuration and data files stored on the server and shared via nfs to solaris and aix clients. The application is crashing on the aix client except the server is sharing those files from a ufs

It wouldn''t be proper to start my first post here without congratulations and thanks to the ZFS team for such an impressive piece of work. Anyway, on to my query. I''ve been trying out ZFS, with a particular focus in reducing latency in a specific application. This application has a fair amount of random writing going on in the background (which, of course, ZFS will make

So after toying around with some stuff a few months back I got bogged down and set this project aside for a while. Time to revisit. <BR><BR> Looking around there still is not a good "these cards/motherboards" work list. the HCL is hardly ever updated, and its far more geared towards business use than hobbyist/home use. So bearing all of that in mind I will need the

Hi All: Why are floating-point operators not supported in D Language? Because they are useless in tracing programs? Regards!

A customer has a zpool where their spectral analysis applications create a ton (millions?) of very small files that are typically 1858 bytes in length. They''re using ZFS because UFS consistently runs out of inodes. I''m assuming that ZFS aggregates these little files into recordsize (128K?) blobs for writes. This seems to go reasonably well amazingly enough. Reads are a

Hi, I''m preparing a personal TPC-H benchmark. The goal is not to measure or optimize the database performance, but to compare ZFS to UFS in similar configurations. At the moment I''m preparing the tests at home. The test setup is as follows: . Solaris snv_37 . 2 x AMD Opteron 252 . 4 GB RAM . 2 x 80 GB ST380817AS . Oracle 10gR2 (small SGA (320m)) The disks also contain the OS

Hi, Can I use DTrace to determine memory status? 1.Total Physical Memory, Used Memory. 2.Total Swap Space and Used Swap Space. I did find few DTrace scripts but had too much in them and I am unable to chop off unwanted lines of code due to lack of knowledge. It will be very helpful if some one can share the piece of code that serves my purpose as mentioned above. Regards, Ramesh. Ramesh

Is there any performance problem with hard links in ZFS? I have a large storage. There will be near 50000 hard links for every file. Is it ok for ZFS? May be some problems with snapshots(every 30 minutes there will be a snapshot creating)? What about difference in speed while working with 50000 hardlinks or 50000 different files? ps: It would be very useful if you give me some links about

I''m putting together a NexentaOS (b65)-based server that has 4 500 GB drives on it. Currently it has two, set up as a ZFS mirror. I''m able to boot Nexenta from it, and it seems to work ok. But, as I''ve learned, the mirror is not properly redundant, and so I can''t just have a drive fail (when I pull one, the OS ends up hanging, and even if I replace it, I have to

Hi all, I am new to Xapian and want to use it with Java. In order to do that I tried to compile the Java bindings. I set XAPIAN_CONFIG and invoked "configure". However "./configure --with-java" exits with an error. Point of failure: checking for jni.h... no checking for jni.h in /usr/lib/jvm/java-1.5.0-sun/include... no checking for jni.h in

I am not a Mac user, but I do use Linux and I would recommend not running R with sudo unless you are an admin ninja. That defensive practice would render the answer to your question moot. It is possible that your problem may have started with inappropriate use of sudo in configuring java, but configuring Java is not on-topic here. -- Sent from my phone. Please excuse my brevity.

Hi Jeff!! I really don?t know if running R CMD javareconf with sudo has posed a problem here, now or in the past. What I know is sometimes it?s the only way to really config it, if I don?t run with sudo, in the end it asks me if I want to overwrite the configuration from root override rw-r--r-- root/admin for /usr/local/Cellar/r/3.4.4/lib/R/etc/Makeconf?

Hi! I?m on macOS 10.13.3 and just installed the new Java 10 using Homebrew Cask. I also have installed R with Homebrew. Everything seems to work fine, however I just get different outputs if I run sudo R CMD javareconf or R CMD javareconf. With sudo I get pointed to Java 9 and without sudo I get pointed to Java 10. I really don?t know why. Without sudo: $ R CMD javareconf

G''day, all, So, I''ve decided to migrate my home server from Linux+swRAID+LVM to Solaris+ZFS, because it seems to hold much better promise for data integrity, which is my primary concern. However, naturally, I decided to do some benchmarks in the process, and I don''t understand why the results are what they are. I though I had a reasonable understanding of ZFS, but now
