Dear R Helpers, First, I apologize for asking for help on the first of my topics. I have been looking at the posts and pages for apply, tapply etc, and I know that the solution to this must be ridiculously easy, but I just can't seem to get my brain around it. If I want to produce a set of tables for all the variables in my data, how can I do that without having to type them into the table

I am playing with a USR (us robotics) USB modem model 5637. in the past I used internal modems and had no issues. One this unit I plugged it in, dmesg says its recogized. I did "ln -s /dev/ttyACM0 /dev/ttyS4" this works. I then did "cu -l /dev/ttyS4" type "AT" and I get OK... looking good. When I "ATDT my number" I get a connection at 1200 baud (which I

It is some time that I using AirMail3 with wine. I have the latest version of Wine but after I configure the Ports from ttyR0 to ttyR7 and running AirMail3 this application is not able to comunicate using the equivalent COM1 .... COM4 ports. I'm not sure if Wine is converting correctly ttyR0 to COM1 and so forth. The result is that for the Hurricane season I can NOT use E-Mail under

Hey all, I''m not sure if this is a ZFS bug or a hardware issue I''m having - any pointers would be great! Following contents include: - high-level info about my system - my first thought to debugging this - stack trace - format output - zpool status output - dmesg output High-Level Info About My System --------------------------------------------- - fresh

Hi all Having managed ZFS for about two years, I want to post a wishlist. INCLUDED IN ZFS - Mirror existing single-drive filesystem, as in ''zfs attach'' - RAIDz-stuff - single and hopefully multiple-parity RAID configuration with block-level checksumming - Background scrub/fsck - Pool-like management with multiple RAIDs/mirrors (VDEVs) - Autogrow as in ZFS autoexpand NOT

Hi, Anyone tried netcell products on Centos 3 or 4? They claim driverless operation under WinXP, but in linux the only doc that is related with CentOS would be the Fedora core 2 (http://www.netcell.com/support/Fedora_Core2_readme.txt) and requires a kernel rebuild. I'd like to know if it would be possible to install CentOS directly on drives on such a card, without needing a build

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 This seems to be an old problem, but I haven't found much about it. SuSE mentions "hwprobe=-pci" but, as far as I know, CentOS doesn't use it. This does stop the machine from booting (mounting /) quite a few times. Logs: SCSI subsystem initialized sym0: <895> rev 0x2 at pci 0000:00:13.0 irq 177 sym0: Symbios NVRAM, ID 7,

I'm using Wine 1.0 on Puppy Linux 3.01 I wrote an application for windows which uses serial communication and I like to use this on linux. Every thing works well, but if I set unsuitable communication parameters (e.g. different baudrates for sender/receiver) wine shows no framing or parity errors. Is there any solution ?

I''m really glad the JSON changes got in, many thanks to all involved, committers and contributors alike :). But there''s still one feature that''s missing to achieve feature parity between the JSON and XML encoding/conversion. And that is the abililty to say in your controller: @authors = Author.find(:all) render :json => @authors.to_json(:only => :name)

Hi, I posted in the Solaris install forum as well about the fileserver I''m building for media files but wanted to ask more specific questions about zfs here. The setup is 8x500GB SATAII drives to start and down the road another 4x750 SATAII drives, the machine will mostly be doing reads and streaming data over GigaE. -I''m under the impression that ZFS+(ZFS2) is similar to

Hey Guys, I have some questions?regarding?a new home server I am going to build in the hopefully very near future (ASAP, I just need to finish planning everything and this is the penultimate?hurdle), I will be creating a software RAID... Lets say I have three drives "knocking" around which are all 1TB SATA II drives but each made by a different manufacturer. I am going to guess that

All, I have a question about calculating the value for the -E stride option to mke2fs. The mke2fs man page says stride=stripe-size Configure the filesystem for a RAID array with stripe-size filesystem blocks per stripe. So stride = size of stripe/blocksize. The size of a stripe is the RAID chunk size * the number of drives in the RAID. My question: are parity disks

Hi, I have a small question about the depth of scrub in a raidz/2/3 configuration. I''m quite sure scrub does not check spares or unused areas of the disks (it could check if the disks detects any errors there). But what about the parity? Obviously it has to be checked, but I can''t find any indications for it in the literature. The man page only states that the data is being

Hi there, i''m building a small NAS with 5x1TB Disks. The disks contains at the moment some data, ntfs as the fs and aren''t a raid. Now my im wondering if its possible to add the parity later. So that i add step by step one disk to the pool. And when i add the last disk, i enable the parity. (i have only one another 1 tb disk to backup the files) Thank you for you replies and

I''m trying to get maybe 200 MB/sec over NFS for large movie files (need large capacity to hold all of them). Are there any rules of thumb on how much RAM is needed to handle this (probably RAIDZ for all the disks) with zfs, and how large a server should be used? The throughput required is not so large, so I am thinking an X4100 M2 or X4150 should be plenty. This message posted from

I want to create native types (despite that fact that apparently nobody wants to) to manage a variety of resources under a common namespace. However, I can''t seem to get the namespacing going right. With a defined type, I can do this: define backup_ninja::config(blah, baz) { ... } But that''s not much use to me, as a defined type just isn''t going to cut the mustard
