Our data server internet link returned this morning at 10:00 UTC (3:00am PDT). It was offline for just over 24 hours, so many connections will be dropped as the servers try to catch up.
2005年5月8日
我们的数据服务器的互联网链接今晨10:00 UTC(3:00am PDT)恢复正常了。它刚好离线超过24小时,由于连接用户过多,许多连接将无法连接服务器。

Due to some network reconfiguring on our subnet here at the lab, the database server shut itself down fearing there was a power outage. It went offline around 01:00 UTC, but is back up now.

由于我们的实验室重新设置子网,数据库服务器已经关闭,以防突然断线。它将大约于01:00 UTC离线,但现在正在备份中。

We are switching the http://setiathome.berkeley.edu/ URL to point here. The SETI@home Classic web site has been moved to http://seticlassic.ssl.berkeley.edu.

我们已经将http://setiathome.berkeley.edu/指向了本网站。传统SETI@home的网站地址已经改为http://seticlassic.ssl.berkeley.edu

The file server containing the upload/download storage hung last evening. We had to power cycle it today to bring it back. It is now back up and the RAID is resync'ing. When this is complete we will bring scheduling and data service back on line.
2005年6月4日
昨晚存储上传/下载文件的文件服务器挂了。我们已经把服务器重启好了。目前正在备份和重新同步。完成后我们会把调度和数据服务器重开。

Update: the scheduling and data servers are back on line. Service may be a bit slow for a while.

调度和数据服务器已经恢复正常。短期内速度可能会慢一些。

We are back online after recovering from a file server crash. We will receive an OS revision soon that should prevent this from happening again. In the meantime we are refraining from doing snapshots (a backup method) on the file server as active snapshots seem to be part of the problem.
2005年6月9日
文件服务器崩溃了,刚刚才恢复正常。为了防止此类事件再度发生,不久我们将安装一个修正版操作系统。同时我们发现频繁给文件服务器做快照(一种备分方法)似乎是导致问题出现的一个因素。

Outage Notice. We will be having an outage tomorrow for a full database backup. This will begin at 17:00 UTC and may last up to 3 hours. The new scheduling server should make clearing the backlog go quicker after the outage.

明天17:00(UTC时间)将有三个小时暂停服务,以进行一次完整的数据库备份。之后,新调度服务器将能够更快的清理后台日志。

We are back online after the backup. By virtue of the new scheduling server we are seeing no post-outage connection drops.

停机备份之后,服务器已经恢复正常工作。由于采用了新的调度服务器,以后应该不会再有连接丢失的情况了。

相关的Technical News:

June 14, 2005 - 19:00 UTC

Yesterday we fixed a bug in the scheduler that caused the fastcgi processes to die after running for a while. Immediately this helped the current backlog, as we removed the extra overhead of continually restarting the cgi processes. Last night the schedulers caught up from all the outages this weekend and we have been operating smoothly all morning.

And then some actual improvement before disaster strikes: As predicted in the previous technical news item, we just upgraded the BOINC scheduling system. Originally both the scheduler and the upload/download functionality were on the same server. This morning we configured the SETI@home classic master science database server to be the new BOINC scheduler while leaving the actual file upload/download on its current server. As the DNS changes slowly take effect both systems are acting as schedulers, but eventually there will be a clean split.

之前seti on boinc的调度和上传/下载服务是在同一台服务器上的,现在项目组将seti classic的主科学数据库服务器重新配置成了seti on boinc的调度服务器,而上传/下载仍保留在原来的服务器上。
