I’ve released a new version of nemulator. Check it out at http://nemulator.com. I have a bunch of servers connected to Nexus 5020s (running NX-OS 4.0(1a)N2(1)) constantly reporting CRC errors on their NICs. CRC errors are reported on the Nexuses’ egress ports, but ingress ports are clean. What’s happening is pretty interesting. The N5k considers packets with an ‘invalid’ EtherType to be bad. If it were [...] With the capabilities that ZFS brings to the table, I’m beginning to think that OpenSolaris just might make a better CIFS server than Windows. Sun has built CIFS support into the kernel, which helps with some of the interoperability challenges faced with Samba in a mixed Windows/*nix environment. Here’s how to set it [...] The Page Up/Down, Home, and End keys don’t work out of the box. Very annoying when you’re trying to scroll through a man page. Fortunately, it’s an easy fix. Export the existing terminfo description: james@opensolaris:~# env TERMINFO=/usr/share/lib/terminfo /bin/infocmp xterm > /tmp/xterm.ti Add the missing key definitions: james@opensolaris:~# echo ‘\tknp=\\E[6~, kpp=\\E[5~, kend=\\EOF, khome=\\EOH,' >> /tmp/xterm.ti Compile the file: james@opensolaris:~# env TERMINFO=/tmp /bin/tic [...] During the install, OpenSolaris creates a ZFS pool, called rpool, and installs to it. Let’s set up two hard drives for redundancy (i.e., RAID-1). Before (note that rpool consists of a single drive): james@opensolaris:~# zpool status NAME [...] One of the primary functions of the server is to host my collection of DVDs/Blu-rays for streaming to a Windows Media Center PC. That said, I need a lot of disk space. It’s predecessor had 6.75TB of disk space; this one will have 16TB. Here’s the hardware list: Lian Li PC-A71F case My existing Linux server, which I use for file storage, email, and web hosting, ran out of disk space. Driven by a desire to play with ZFS, I decided that its replacement would run OpenSolaris. This is the first in a series of posts detailing the build and what I’ve learned along the way. |
