It's better than nothing, but sometimes not by a whole lot.
one server that's got two bad sectors, which SMART reports. I've followed the instructions on how to make the log messages go away, and
<snip>
No joy - it's a plain SATA drive, the root drive on a server we use for backups. ext3, and no, I'm not going to change filesystem types.... The real thing is why does SMART ignore the results of badblocks (for those who aren't sure, that's invoked when you do fsck -c), and for that matter, why the drive (Seagate ST3170811AS) doesn't automagically
relocate those
blocks.
Auto relocation happens ONLY when writing to foobar sectors. The drive WILL NOT relocate sectors that you are reading from because it cannot trust the content.
SMART reports the number of sectors that have been reallocated. That means, the drive was writing to a sector, found out it was unreliable and decided to remap that sector. It is not abnormal for drives to develop _a few_ bad sectors over the years.
Agreed. And these two bad sectors developed many months ago, and the number is not increasing, so I'm not really worried about them; all I want is to make the irritating messages in the logfiles go, and stay, away.
