ceph的数据存储之路(8) -----pg 的数据恢复过程

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 2016-10-26 更新start—————————————————————————————————————— 感谢 大水牛提出的疑问：对与本文中第二节，OSD恢复时常用的基本概念解析中对acting和up集合的描述问题，在研究ceph之初的时候我也不太懂acting和up集合的区别，然后查看资料从博客 http://blog.csdn.net/changtao381/article/details/49125817 引用了这部分概念的解释，也感谢这位博主的努力和付出。在这里面对acting和up集合的解释确实出现了一点点的小纰漏。这里更正一下。 当@大水牛这位大神提出了对acting和up集合的质疑，然后我去查找了之前自己在分析ceph时抓取的一些log，去分析一下 acting和up集合。 log抓取的时机：杀掉一个osd.0进程,再重新启动这个进程，然后分析他的log，在这个log里加了一些日志供分析。截取部分日志如下： 7fba68b79700 10 osd.0 pg_epoch: 27 pg[0.0( v 9'2 (0'0,9'2] local-les=26 n=1 ec=1 les/c 26/26 24/25/24) [2,1]/[2,1,0] r=2 lpr=25 pi=22-24/2 luod

问题 I'm working on building the twitter clone app in Hartl's Rails Tutorial. I cloned my git repo (https://github.com/stewartmccoy/rails_tutorial) and put code on to my personal computer, which had previously been on my work computer. So, my developer environment might be slightly different than what's specified in my Gemfile. My environment: Mac OS 10.6.8 Rails 3.2.13 ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-darwin10.8.0] * LOCAL GEMS * actionmailer (3.2.13, 3.2.11, 3.2.1) actionpack

Can't connect to PostgreSQL database on Heroku using Ruby - could not translate host name

由 孤街浪徒 提交于 2019-12-12 08:42:09
问题 I'm using Ruby (not Rails) and connecting a PostgreSQL database. I've been trying to get set up on Heroku, but I'm having problems starting the application. Running the application locally works fine. My local .env looks like: postgres://DATABASE_URL=localhost And the Ruby connect to connect to the database looks like: @@db = PGconn.open(:hostaddr => ENV['DATABASE_URL'], :dbname => '(dbname)', :password => '(password)') When I push to Heroku the app crashes on that line, and writes this error

How pg-promise handles multiple clients in the same app

由 左心房为你撑大大i 提交于 2019-12-11 21:51:43
问题 I am creating code using just the pg module, where I have a general function for executing queries. This function can create a client on the spot if it doesn't take an already existing client as an argument. Or it can use an already existing client to execute a query. So I can call this function like (pseudocode) const {Client} = require('pg'); const clientobj = {user:...} generalQuery(text, params, client){ if !client{client = new Client(clientobj);} client.query(text , params) client.end();
