Don't know for the whole drive yet (currently running) but when I did a mkraid on a raid5 array using 4 partitions on the same drive the sync thread ended and left the array in degraded mode after a bunch of : May 24 02:05:06 twins kernel: hdd: dma_intr: status=0x51 { DriveReady SeekComplete Error } May 24 02:05:06 twins kernel: hdd: dma_intr: error=0x40 { UncorrectableError }, LBA sect=2097375, sector=2097298 May 24 02:05:06 twins kernel: end_request: I/O error, dev 16:41 (hdd), sector 2097298
Then I tried to zero the offending sectors with a slight margin : [root@twins root]# dd if=/dev/zero of=/dev/hdd1 count=200 bs=512 seek=2097200 dd: writing /dev/hdd1': Erreur d'entrée/sortie 113+0 enregistrements lus. 112+0 enregistrements écrits.
Same error each time, seems sector 2097312 is not my friend.
dd if=/dev/zero of=/dev/hdd bs=<cylinder_size> running.
Too bad lsof doesn't show offsets... I can't tell if dd passed the offending sector :-|
