Hi, My solaris storage hangs. I login to the console and there is messages[1] display on the console. I can''t login into the console and seems the IO is totally blocked. The system is solaris 10u8 on Dell R710 with disk array Dell MD3000. 2 HBA cable connect the server and MD3000. The symptom is random. It is very appreciated if any one can help me out. Regards, Ding [1] Aug 16

According to various posts the LSI SAS3081E-R seems to work well with OpenSolaris. But I''ve got pretty chilled-out from my recent problems with Areca-1680''s. Could anyone please confirm that the LSI SAS3081E-R works well ? Is hotplug supported ? Anything else I should know before buying one of these cards ? Thanks, Arnaud

Hi. I'm using Debian. Is this a Redhat-only list, or is it only hosted by RedHat? I recently changed my filing systems over to ext3, but deliberately left the forced boot check parameters alone so my system checks after 20 mounts. I notice that the fsck takes a good ten times longer than under ext2, to perform the cleanly unmounted check. (On the occasion where I did unmount dirtily, the

Hi, I am seeing a >10x as slow performance when trying to complete a "send/receive" from an Outlook 2010 client to Dovecot via IMAP, but only when the LAN is fully loaded with other traffic, EG file copying. It seems the problem is when outlook is trying to identify folders that have changed since last "send/receive" thus traversing the hierachy. Observations: -

OK, I have made a little search about this "problem" that apparently occurs only on Windows platform... (but I am sure most of you are already aware of it): the slow down is due to the adoption of a different algorithm for pow in mingw 3.x. This is motivated by some other changes in mingw. Here is a quote of Danny Smith that did this change: >When mingw changed default FPU settings

The move to memcached_client 1.6.5 in Rails 2.3 seems to have made the Rails cache about 10x slower. Since that''s the opposite effect I would expect, I was hoping somebody would explain where I''m misreading these numbers? I noticed my fragment caching was slow -- it shouldn''t take 2ms just to read a 2k string from a localhost memcached server: Cached fragment hit:

I am bumping this thread because I too have the same question ... can I put modern 3TB disks (hitachi deskstars) into an old x4500 ? If not, would the x4540 accept them ? -- This message posted from opensolaris.org

Hello everyone, As one of the steps of improving my ZFS home fileserver (snv_134) I wanted to replace a 1TB disk with a newer one of the same vendor/model/size because this new one has 64MB cache vs. 16MB in the previous one. The removed disk will be use for backups, so I thought it''s better off to have a 64MB cache disk in the on-line pool than in the backup set sitting off-line all

Hi, I have OpenSolaris on an Amd64 Asus-A8NE with 2gig of Rams and 4x320 gig sata drives in raidz1. With dd, I can write at quasi disk maximum speed of 80meg each for a total of 250meg/s if I have no Xsession at all (only console tty). But as soon as I have an Xsession running, the write speed drops to about 120MB/s. Its even worse if I have a VBoxHeadless running with an idle win2k3 inside. It

I have been reading about software raid. I configured my first software raid system about a month ago. I have 4 500 Gig drives configured in RAID 5 configuration with a total of 1.5TB. Currently I configured the complete individual drivers as software raid, then created a /dev/md0 with the drives I then created a /file_storage partition on /dev/md0. I created my /boot / and swap partitions on

Hi all, I am trying to plot the fitted trajectories for each individual from an individual growth model (fit with a linear mixed effects model in lme). How can I plot each person's trajectory in the *same* panel, along with the mean-level trajectory? Below is an image of a plot similar to what I'm trying to create (from: http://jpepsy.oxfordjournals.org/content/31/10/1002/F6.large.jpg):

Hi, I am seeing that doc = index[''mykey''] index.update ''mykey'', doc is about 10 times slower than doc = Document.new doc[''id''] = ''mykey'' index << doc It looks like #update is _much_ slower that #<<. Is it as expected? Sergei. -- Posted via http://www.ruby-forum.com/.

We have some code that uses REXML, that when executed outside of Rails as a standalone rb file, runs fine. Once we run the code inside of Rails, it is dog slow. I know REXML is slow, buggy, sucks, etc., but my question is what cause the performance to degrade like that. Thanks. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google

Is Samba typically slower sending files than receiving? I have seen this both at home and at work. Sometimes the throughput is 1/2 when I copy files from Samba than when I copy to Samba (From WinNT and Win95/98) The Players -------------------------------------------------------------------------------------- I have been playing with the options for three days. I have an NT server that is old.

hi folks, we had a nice old compaq Prosignia300 server - Pentium75 but nice architecture. It won't serve as a workstation but from what I read of linux and samba it should have done very well as a server on our win95 network. However, after setting all the win95 boxes up with tcp/ip to see the samba server, and copying all our medical databases across, we found that the response time

Hi, On a vista pc we run Syncrosvn client to check out svn repositories to a samba share. It works but on Vista this takes much longer than on windows xP. Checkout or status check on local disk work normally. (tried the same on a different vista pc, same problem..) To troubleshoot this I created a smaller test SVN repository to make it easier to read network captures. (I made a svn repository
