Freebsd zfs backup script

I went with ECC RAM because scary cosmic radiation (and because the FreeNAS community convinced me ECC was an absolute requirement). The RAM is also registered/buffered because the DIMM size is so large. See this interesting article on more information on ZFS and the supposed dire need for ECC RAM. 64GB is on the high side, but 32GB is the next step down and that would have been cutting it close. When I eventually fill the last 8 HDD bays in my chassis, I shouldn’t have to upgrade my RAM. RAM: Samsung M393A2G40DB0-CPB (4x16GB, 64GB total) – This is one of the SuperMicro-recommended RAM models for the X10SRL-F motherboard; all the other models are really hard to find.

I measured the wood strip to be a very tight fit and zip-tied it to the fans to secure it in place. You can see this wood strip in the 3rd and 4th pictures in the section above. I even cut out little divots where the zip ties cross the top of the wood strip to be extra cautious. Air was flowing from the CPU side of the HDD fan wall back over the top of the fans rather than coming through the HDD trays, so I cut a long ~3/4” thick strip of wood to block the space between the top of the fans and the chassis lid.

While my preferred setup would be PostgreSQL, and Nginx, the majority of the documentation is based on the recommended setup. As of now there is no ‘official’ documentation for Nginx. It would be nice to see these options better supported in the future.

Conf with the new names. I know MFSBSD has something like this, but a polished up hybrid of the two should likely be part of the base system if something is not already availableThis would be a great “Junior Job”, if say, a viewer wanted to get started with their first FreeBSD patchMog: A different take on the Unix tool catDo you abuse cat to view files. To start with we have tabs, because when you (the user) backspace over a tab you want the cursor to jump all the way back, not just move back one space. Couple of notes before you start installing new packages and expecting wayland to “just work”First, this does require that you have working DRM from the kernel side. 1 “Eclectic Eagle”, based on FreeBSD 11 ReleasedWhy you should start programming on UNIXOpenSMTPD Mail FilteringFeedback/Questions Zane – Databases and Jails Mohammad – USB Install Chuck – Updating Jails David – Lumina / LXQtSend questions, comments, show ideas/topics, or stories you want mentioned on the show to [email protected] Each operation has a match command and an action command. Next, not all desktops will “just work”. C in the ttydisc_rubchar functionPS: If you want to see the kernel’s handling of backspace in action, you usually can’t test it at your shell prompt, because you’re almost certainly using a shell that supports command line editing and readline and so on. Nvidia with modesetting should be supported. Use ifconfig_=”” settings in rc. The FreeBSD code for this is in sys/kern/tty_ttydisc. Other kernels don’t seem to bother with this optimization. Txtmog is a tool for actually viewing files, and it adds quite a few nice featuresSyntax highlight scriptsPrint a hex dump of binary filesShow details of image filesPerform objdump on executablesList a directorymog reads the $HOME/. Did you know cat is meant for concatenating files, meaning: cat part1 part2 part3 > wholething. Beastie BitsFaces of FreeBSD 2017: Joseph KongOPNsense 17. When you hit backspace, the kernel tty line discipline rubs out your previous character by printing (in the simple case) Ctrl-H, a space, and then another Ctrl-H. Then we have the case when you quoted a control character while entering it, eg by typing Ctrl-V Ctrl-H; this causes the kernel to print the Ctrl-H instead of acting on it, and it prints it as the two character sequence ^H. Of course just backing up one character is not always the correct way of erasing input, and that’s when it gets complicated for the kernel. You may need to grab experimental Weston for compositor. A reasonably useful config file is generated when you first run it. So how is it doing that. When you hit backspace to erase that, of course you want both (printed) characters to be rubbed out, not just the ‘H’. The answer turns out to be basically what you’d expect, although the actual implementation rapidly gets complex. KDE / Gnome (And Lumina) and friends will grow Wayland support in the future, so don’t expect to just fire up $whatever and have it all work out of box. For us on the TrueOS side we are interested as well, since we want to port Lumina over to Wayland soon(ish)Happy Experimenting. So the kernel needs to keep track of that and rub out two characters instead of just one. For each file you give to mog it will test each match command in turn, when one matches it will perform the action. My usual way to see what the kernel is doing is to run ‘cat >/dev/null’ and then type away. This is brand new functionality for FreeBSD, and the maintainers will want to hear your results. Command line editing requires taking over input processing from the kernel, and so such shells are handling everything themselves. This raises an interesting question, because when you’re typing something into a Unix system and hit your backspace key, Unix sure erases the last character that you entered. First of all, (And I was wondering how they would deal with this) it has landed in the “graphics” category, since Wayland is the Anti-X11, putting it in x11/ didn’t make a lot of sense. The kernel has a certain amount of code to work out what column it thinks you’re on and then back up an appropriate number of spaces with Ctrl-Hs. Create /usr/local/etc/ifmap in the following format: 01:23:45:67:89:ab eth0
01:23:45:67:89:ac eth1That’s it. And you thought the backspace key would be simpleFreeBSD ports now have WaylandWe’ve discussed the pending Wayland work, but we wanted to point you today to the ports which are in mainline FreeBSD ports tree now. You’ll want to grab TrueOS or build from Matt Macy’s FreeBSD branches on GitHub before testing on any kind of modern Intel GPU. How Unix erases things when you type a backspace while entering textYesterday I mentioned in passing that printing a DEL character doesn’t actually erase anything. Mogrc config file which describes a series of operations it can do in an ordered manner. Chris then provides an example, from IllumOS, of the kernel trying to deal with multibyte charactersFreeBSD also handles backspacing a space specially, because you don’t need to actually rub that out with a ‘b b’ sequence; you can just print a plain b.

Early examples include the Oracle Exadata Database Machine X2-8, and the first Oracle Exalogic Elastic Cloud, both introduced in late 2010. Oracle’s SPARC-based systems are some of the most scalable, reliable, and secure products available today. Sun’s prized software portfolio has continued to develop as well, with new releases of Oracle Solaris, MySQL, and the recent introduction of Java 7. During 2011, Oracle introduced the SPARC SuperCluster T4-4, a general-purpose, engineered system with Oracle Solaris that delivered record-breaking performance on a series of enterprise benchmarks. Oracle acquired Sun Microsystems in 2010, and since that time Oracle’s hardware and software engineers have worked side-by-side to build fully integrated systems and optimized solutions designed to achieve performance levels that are unmatched in the industry. Oracle invests in innovation by designing hardware and software systems that are engineered to work together.

Rear Fans: Noctua NF-R8 PWM – As I mentioned above, the stock chassis fans are super loud. I was able to use the hot-swap fan caddies that came with the chassis, but I have it bypassing the hot-swap plug mechanism that SuperMicro built in. These Noctua 80mm fans fit perfectly in their place.

The next day, when server is back online, the script will successfully create another daily snapshot pool_0/[email protected] but will not be able to successfully send it to backup because pool_0/[email protected] is missing. To recover from this problem I’ll need to manually perform an incremental zfs send using pool_0/[email protected] and pool_0/[email protected]:. Now say that the script was not able to create pool_0/[email protected] on server because it was offline for some reason. Consequently, it was not able to successfully replicated this snapshot to backup.

Recently, I replaced one of the Windows fileservers at $dayjob with a Debian-based Samba server. 1, dated April 23 2015), most, if not all of the stability problems I had with earlier versions are gone. For the data storage, I chose ZFS on Linux. I have been running ZFS on Linux on my backup servers for a while now, and it seems that with the latest release (0.

Drive activity information is carried over the SAS cable and all my fans are connected directly to the motherboard. The SuperMicro backplanes have a ton of jumpers and connectors for stuff like I2C connectors, activity LEDs, and PWM fans, but I didn’t use any of those. If you’re interested, check the backplane manual on the SuperMicro website for more information on all the jumpers and connectors. Some of the screws are a little tough to access (especially the bottom one closest to the PSUs), but they all came out easily enough with some persistence. With the fan wall gone, swapping out the EOL backplane (which came pre-installed in my chassis) for the new version I purchased was pretty easy. There are 6x Molex 4-pin power connectors that plug into the backplane to provide power to all the drives.
