Infortrend

快被盘阵折腾得精疲力尽的delphij和quakelee总算看到了一点曙光——quakelee同学总算在周五晚上把盘阵搞死了。

今天他说盘阵终于进入了调试界面。不管怎么说，困扰我们许久的盘阵的问题，总算是有了一点眉目。不知道台北普安科技(InfoTrend)的工程师是否能看出些端倪并修正firmware。但愿如此，我已经把我的MSN头像换成关公了。

And finally, it happend.

On Monday, one of our server, running FreeBSD, panic’ed with “ffs_clusteralloc: map mismatch”. This message is quite uncommon and should only happen when there is some “event” with the memory or hard disk.

I have suggested our administrator to reboot and do “fsck” on the volume, since it has very small block size and can not be checked background (I have made a change to warn about this to FreeBSD, and was MFC’ed to 5-STABLE so you will get the feature in 5.4-RELEASE). Unfortunatelly, the check is so slow and we start to suspect whether there is some hardware problem.

It seems that if one host is fsck’ing and the other is trying to boot, then the controller will halt. I’m so tired and sick about this!
