Hi, I got a problem to recover data from Fedora core 1 hosts when
hard drives fail. I know that the disks fail because there are error messages
like the following logged in /var/log/messages. ….. arc144: Apr 24 12:52:53 arc144
kernel: hda: dma_intr: status=0x51 { DriveReady SeekComplete Error } arc144: Apr 24 12:52:53 arc144
kernel: hda: dma_intr: error=0x40 { UncorrectableError }, LBAsect=90186647,
sector=52432952 arc144: Apr 24 12:52:53 arc144 kernel: end_request: I/O
error, dev 03:0b (hda), sector 52432952 ….. My question is: How to figure out the file|directory
occupying the failed sector|LBAsect? If I can figure it out then I can skipped
the files|directories since the failed files will sometimes bring the failed
drive to completely inaccessible status on Fedora Core 1 hosts, which is quite
different from my former Redhat 8.0. Another questions is, what is the exact difference between
LABsect and sector in the above message? Can I find any helpful&complete
info on ext2|ext3 internals? At least related to disk space allocation. Any suggestions are greatly appreciated. Thanks. --Guolin Cheng |
