是不是磁盘出现了坏道？

Chowroc

有一个系统的日志 /var/log/messages 中反复出现如下的记录，我怀疑是不是磁盘出现了坏道：

哪位经验丰富，能否给点提示？

谢谢

我的硬盘坏的时候，和这个错误差不多。。。硬盘别再用了，赶快抢救吧。。

我想也是 :thank

但是看看这个系统，做了 raid5 的，但是基本上每次如果进行大量数据传输的时候就出问题：
Mar 27 09:14:24 four-cpus kernel: EXT3-fs error (device sdb1): ext3_new_block: Allocating block in system zone - block = 418611201
Mar 27 09:14:24 four-cpus kernel: Aborting journal on device sdb1.

Mar 27 14:46:47 four-cpus kernel: EXT3-fs error (device sdb1): ext3_remount: Abort forced by user

然后 sdb1 就变成只读文件系统了。:ask

还是觉得是硬盘的问题，或者控制器的问题，你的 RAID 5 是 内核的，还是卡的？

我这里用 RAID5，似乎没见过这个问题，不过我也没用 ext3，用的是 reiserfs。如果允许，试试  reiserfs，我想我的数据传输也不小，不过我没碰到这个问题。
