Hi list, I googled around but couldn''t find anything on whether someone has good or bad experiences with the Caviar *Blue* drives? I saw in the archives Caviar Blacks are *not* recommended for ZFS arrays (excluding apparently RE3 and RE4?). Specifically I''m looking to buy Western Digital Caviar Blue WD10EALS 1TB drives [1]. Does anyone have any experience with these drives? If

Hi, I am trying to replicate Engle and Manganelli's paper Conditional Autoregressive Value at Risk (CAViaR) by Regression Quantiles. I have the Matlab code which I cannot get to work as I have never used Matlab before, does anyone know if there is the same code available to estimate the CAViaR models in R? Thanks, Shane -- View this message in context:

Mr./Ms. Thank your help I need the code of quantile regression - estimation of CAViaR, would do you like to help me! regards, tangyong school of managemnet ,fuzhou university, China [[alternative HTML version deleted]]

How is it possible to estimate the conditional autoregressive Value-at-Risk model qantile_t(tau)=a0+a1*qantile_(t-1)(tau)+a2*abs(r_(t-1)) see http://www.faculty.ucr.edu/~taelee/paper/BLSpaper1.pdf (page 10)) of Engle & Manganelli in R? The qantile_(t-1)(tau)-term causes headache. Kind regards, Jaci -- "Ein Herz f?r Kinder" - Ihre Spende hilft! Aktion: www.deutschlandsegelt.de

I believe I've posted before about one of the speed issues we were having, of backups taking many, many hours that should *not* take that long. My manager and I finally nailed it down to the h/d itself. Identical boxes, and he tried a backup of one system which took under two hours, while the same regular one rand nearly six. I'd been googling on and off for weeks, and this morning, ran

I know that this has been well-discussed already, but it''s been a few months - WD caviars with mpt/mpt_sas generating lots of retryable read errors, spitting out lots of beloved " Log info 31080000 received for target" messages, and just generally not working right. (SM 836EL1 and 836TQ chassis - though I have several variations on theme depending on date of purchase: 836EL2...

Hello, Having a problem with software RAID that is driving me crazy. Here's the details: 1. CentOS 6.2 x86_64 install from the minimal iso (via pxeboot). 2. Reasonably good PC hardware (i.e. not budget, but not server grade either) with a pair of 1TB Western Digital SATA3 Drives. 3. Drives are plugged into the SATA3 ports on the mainboard (both drives and cables say they can do 6Gb/s). 4.

This is a bit long-winded, but I wanted to share some info .... Regarding my earlier message about a possible race condition with mdadm, I have been doing all sorts of poking around with the boot process. Thanks to a tip from Steven Yellin at Stanford, I found where to add a delay in the rc.sysinit script, which invokes mdadm to assemble the arrays. Unfortunately it didn't help, so it

Like many others, I am looking to put together a SOHO NAS based on ZFS/CIFS. The plan is 6 x 1TB drives in RAIDZ2 configuration, driven via mobo with 6 SATA ports. I''ve read most, if not all, of the threads here, as well as sbredon''s excellent article on building a home NAS, yet I still have a number of unanswered questions. I was leaning heavily towards the M2N-E for a while,

Hello again. Do any of you have one of the 'new' HDDs with 4kB Sectors currently in use? I would upgrade to the 4kB disks but I don't know if this might be problematic as I intend to use ZFS w/ RAIDz or at least a classic RAID6. How might this affect performance under 5.5 and how do I go about setting up the alignment of the partitions I use? Kind regards Dawid Horace

Good day. Thanks in advance for any help. I have a Tyan S2895 (Thunder K8WE) with 2 275 Opterons and the latest (1.02) bios. It appears to have an nVidia nForce SATA chipset which connects to a 250gb WD Caviar SATA drive. Using the CentOS 4 update 2 x86_64 DVD, the install is peachy until half-way through the "performing post install configuration" bit. Then it hangs forever. I

So, I have a client that has an internal use application that needs an ancient version of libc5.? That's not a typo; libc5.? Before the server that ran it died about a year and a half ago (said server was an AMD K6-2/450 with a 6GB Western Digital Caviar drive that had been spinning nearly continuously for almost 20 years!) it was running on Red Hat Linux 5.2.? The last version of CentOS

Hi people, I am building a cheap remote rsync backup server using a software raid 5 array of 4 500GB disks. What I have available on the market is: 1.

If y'all remember the problem I posted a while back, with a 3TB drive for userspace loosing it on a server, and spitting DRDY errors, but which work on everything else. Well, enough research, and conversation, and I may have found the problem: it's a Caviar Green, meant for a desktop, and the controller in the server has issues, because it uses TLER:

Mandrake Linux 9.0 here: I installed alsa-utils from CD1 with MCC:Software Install: in /var/log/syslog these error messages appeared (SEE BELOW): "XT3-fs error (device ide0(3,2)): ext3_new_block: Allocating block in system zone - block = 294914" Then I rebooted (because I wanted to boot in runlevel 3 to see whether I could play sound..., not relevant here). Error bootmessages appeared

I installed R project 1.9.0 on Windows XP. The installation went well. Then, I rebooted. Next, I clicked the icon under Programs in the Start menu and received this error, "Fatal Error: Invalid HOMEDRIVE". I clicked OK to the error message. The program does not start. I went to a DOS prompt and did "echo %HOMEDRIVE%" and it returned "C:". This letter is a valid

Greetings, out of fun and to investigate claims about alleged bgfsck resource hogging (which I could not reproduce) posted to news:de.comp.os.unix.bsd, I pressed the reset button on a live FreeBSD 5-STABLE system. Upon reboot, fsck -p complained about an unexpected softupdates inconsistency on the / file system and put me into single user mode, the manual fsck / then asked me to agree to
