We've been running 1.1 on about half of our servers for about a week now. Ive mailed before that I was pleasantly surprised by its better use of resources. Here's a graph showing that fact. Server load in the last 10 days. http://uwimages.smugmug.com/photos/286355874_9FNp2-L.png Cor

...w. also, making > enclosure 2" larger than fan will help reduce restriction. he said 'server rack'. thats a probably 6' tall cabinet filled with servers, each of which has likely dozens of high speed fans.

Has anyone come across a device that could cancel out the noise from servers, ie. the fan noise? I have a server rack near my office and would like to see if i can decrease the noise level. It would seem to me that the steady drone of the fans could be cancelled out to a large extent.

...eate a whole bunch of RAID0 1-disk LUNs and expose those. Great.. except that the MD3000i only lets you create 16 LUNs and we have 44 disks total. :) Anyone tried this? I guess our best bet will be to just do all the RAID stuff on the MD3000i and export one LUN to ZFS. Ray [1] http://don.blogs.smugmug.com/2007/10/01/dell-md3000-great-das-db-storage/

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

Preparing to build a small replacement server (initially built in 2005) and normally for the OS I would buy 2x500GB drives and deploy in a RAID 1 configuration. Now we have SSD drives available - does just a single SSD drive offer the same reliability or is there advantage in deploying two in a Raid 1 config? Also, what form factor / interface is best for the SSD OS boot device on a server

Hi, I just installed 2009.06 and found that compression isn''t enabled by default when filesystems are created. Does is make sense to have an RFE open for this? (I''ll open one tonight if need be.) We keep telling people to turn on compression. Are there any situations where turning on compression doesn''t make sense, like rpool/swap? what about rpool/dump? Thanks, ~~sa

I have a 12 disk ZFS+ volume and this morning tried to look at some data on it and the ''ls'' command just hung. So I ran a ''zpool status'' which also proceeded to hang and return no data. I had to leave for work and when I came home the computer had shut down, which is weird. So I started the machine back up and I was able to run a zpool status, it returned

Hi, after a machine has been up for a few days the following command hangs when running `puppet apply` (--debug added to see what was hanging) Service[ntpd](provider=debian): Executing ''/etc/init.d/ntp status'' Running `/etc/init.d/ntp status` works fine when run as root or as myself. Is there any way to figure out what puppet is hanging on? Is it hanging on its next action
