无法在ubuntu服务器12.10上挂载大型外部大磁盘(3TB)

Question

当我用message或usb连接外部磁盘时，显示器显示以下消息：

[534.032718] ata3: exception Emask 0x10 ASct 0x0 Serr 0x5840000 action 0xe frozen [534.033063] ata3: irq_stat 0x00000040,connection status changed [534.033403] ata3: SError: { CommWake LinkSeq TrStaTrns DevExch }

[24.360696] ata3: exception Emask 0x10 ASct 0x0 Serr 0x5950000 action 0xe frozen [24.360708] ata3: irq_stat 0x00000040,connection status changed [24.360717] ata3: Serr: {PHYRdyChg CommWake Dispar LinkSeq TrStaTrns DevExch } [30.084024] ata3.00: revalidation failed (errno=-5)

**fdisk可以找到外部磁盘，我使用分离设置。但是使用挂载磁盘显示了以下消息：

message,can't mount disk**

[873.367903] EXT3-fs error (device sdb1): ext3_check_descriptors:Block bitmap for group 320 not in group (block 540385280)! [873.369151] EXT3-fs (sdb1): error group descriptors corrupted mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg|tail or so

Answer 1

我不确定，但也许你对3TB驱动器的4K块有问题。这应该是可能的。我有一个有很多3TB驱动器的存储空间，运行旧的debian压缩程序，但是我有一个3.4.8内核，我很快就会升级到ubuntu12.04LTS。

我查看了ext3 src，并在( http://lxr.free-electrons.com/source/fs/ext3/super.c )中找到了错误消息：

/* Called at mount-time, super-block is locked */
static int ext3_check_descriptors(struct super_block *sb)

所以你的ubuntu看不懂4K设备。看看这里：http://lwn.net/Articles/377895/
