How to locate a bad block on disk reported by SMART?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi list,

I'm getting this e-mail daily, since a few days:

The following warning/error was logged by the smartd daemon:

Device: /dev/hda, 1 Currently unreadable (pending) sectors

For details see host's SYSLOG (default: /var/log/messages).

You can also use the smartctl utility for further investigation.
No additional email messages about this problem will be sent.

From /var/log/messages, I can read this:
Feb 1 00:20:38 home smartd[3612]: Device: /dev/hda, 1 Currently unreadable (pending) sectors

... and from and early SYSLOG (named messages.1), this:
Jan 25 19:11:28 home kernel: hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
Jan 25 19:11:28 home kernel: hda: dma_intr: error=0x40 { UncorrectableError }, LBAsect=33336872, sector=33336872
Jan 25 19:11:28 home kernel: ide: failed opcode was: unknown
Jan 25 19:11:28 home kernel: end_request: I/O error, dev hda, sector 33336872
Jan 25 19:11:29 home kernel: hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
Jan 25 19:11:29 home kernel: hda: dma_intr: error=0x40 { UncorrectableError }, LBAsect=33336872, sector=33336872
Jan 25 19:11:29 home kernel: ide: failed opcode was: unknown
Jan 25 19:11:29 home kernel: end_request: I/O error, dev hda, sector 33336872
Jan 25 19:11:29 home kernel: Buffer I/O error on device dm-0, logical block 1581163

I remember getting and error that day doing a massive copy of a bounch of files from one filesystem to another. But I moved so many things that I don't know for sure which filesystem has the bad block.

I've been trying Google to find how to deal with this issue, and I've
found this document:
http://smartmontools.sourceforge.net/BadBlockHowTo.txt
which explains how to find the sector, the i-node and the file, and how
to write zeros to it (to force the hardware to mark the sector as bad).
But I couldn't figure out how to find which is the faulty partition.
Besides, My root and home partitions are on LVM, and I don't want to
mess up any metadata... I mean, I don't know if the low level approach
described there applies flowesly to a partition into a LVM volume.

Could anybody help me sorting this out?

TIA,

--
Mariano
