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.

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

Does anyone know if there is support in Java for creating holes in a sparse file (like one can do via fcntl(F_FREESP) in C)? Would like to avoid writing JNI code if there is already support for this somewhere in the JDK. Chuck

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? Would

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

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

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

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

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

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

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

Hello zfs-discuss, I''m writing a script to do automatically snapshots and destroy old one. I think it would be great to add to zfs destroy another option so only snapshots can be destroyed. Something like: zfs destroy -s SNAPSHOT so if something other than snapshot is provided as an argument zfs destroy wouldn''t actually destroy it. That way it would

I just had a quick play with gzip compression on a filesystem and the result was the machine grinding to a halt while copying some large (.wav) files to it from another filesystem in the same pool. The system became very unresponsive, taking several seconds to echo keystrokes. The box is a maxed out AMD QuadFX, so it should have plenty of grunt for this. Comments? Ian

if you have N processes reading the same file sequentially (where file size is much greater than physical memory) from the same starting position, should I expect that all N processes finish in the same time as if it were a single process? In other words, if you have one process that reads blocks from a file, is it "free" (meaning no additional total I/O cost) to have another process
