you can install linux on it and a desktop and click around but actually starting firefox (well, iceweasel) will make you thrash swap

carry on then posted:that's the one that requires a flatten and reinstall to get the new version, right? They've caught on that people don't want to do that and actually test upgrade paths now. Plus, you can just stick your home directory on a different partition and get all back up to speed in like ten minutes after the reinstall, if you want.

so i've been looking at sensu/influxdb/grafana for monitoring/metrics instead of nagios/munin in tyol2015 does it really expect me to compile rubby c extensions on nodes do i really have to construct my own dashboards instead of bundling something sane by default like munin looks like nagios/munin is still the pro choice, sadly

For a small number of servers graphite backend, seyren or bosun for alerting , grafana for visualisation. If you need to be recording millions of points per minute or need HA Grafana or metrilyx / OpenTSDB / Bosun If they ever get it to work properly influx has graphite support and a better query language but they keep making breaking changes to it because the storage backend doesn't scale and clustering doesn't work.

MALE SHOEGAZE posted:honestly the biggest loss in the event of something bad are private keys. what do you all do about that? Backed up onto a thumb drive with a very very long passphrase. Also, create a 128-bit computer-generated passphrase (use keepass) that you can store on your computer keychain. That way, your long passphrase is never in cleartext and your computer-generated passphrase makes it easy to backup your data yet impossible for anyone to actually try and guess. Unless you pull a debian and screw up your random number generator or something.

If you haven't used time machine, you don't know how easy it is. The interface is seriously magic and is worth the switch to Mac OS alone. What I really wanted to post was the comedy option. Put your home partition on LVM and create snapshots. Your snapshots will maintain a perfect image of what your filesystem was like when the snapshot happened, and the actual snapshots are really really quick. It's like having time machine! For engineers. Once you have a need to track down a specific file version, you will be mounting and unmounting partitions like a pro.

or just use btrfs, snapshotting there is a new world compared to lvm. use btrfs for timemachine on linux.

rhel 7 included btrfs as a "technology preview," which must mean it's stable enough for best-effort support. not exactly a ringing endorsement but still a lot further than reiserfs was ever going to get

the interesting bit is whether chris mason will murder anyone as btrfs reaches maturity p. sure this fs stuff is a 'breeds there a man' sort of situation

using btrfs with a old kernel (3.x) is inadvisable i subscribe to the btrfs mailing list and there are regular bug reports and fixes, including one from today in which a btrfs dev (employee of suse i think) says "fixed in 4.4-rc1, patches tagged for backports to 4.2 and 4.3 but not applied yet" i have had btrfs oddities even in kernel 3.19, and booting the machine with 4.2 magically fixed it

btrfs is a *lot* better than it was even a year ago, but it still has bugs, and if you need fixes for those bugs you will need to be able to run new kernel versions that have those fixes as loving terrible as it is that ubuntu breaks kernel ABI compatibility, i did really like that i could sidestep a btrfs issue by apt-get installing linux-generic-lts-wily, rebooting, and having the same filesystem work perfectly fine under 4.2

But that might not be what you want. Just bind-mount the dir you want hardlinked. e.g. mount --bind dir_i_want_hardlinked newdir
