 |

Hi folks,
I have here one weired pending sector on one of my disks, long and short tests finished successfully several times but the pending sector alert is still reoccuring in log and I'm receiving it in mail every 24h.

Funny thing on it all it that there is no other note in log about the sector number, nor in the selftest results, here is the ouptut of smartctl -a /dev/hda

As you can see all test were successful and no errors were logged at all.

196 Reallocated_Event_Count 0x0032 100 100 000 Old_age Always - 1

In past there was one rellocated sector, sector number was listed in long test result and it was corrected.
Now there is only Current_Pending_Sector and no sector number mentioned at all.
| Code: | 197 Current_Pending_Sector 0x0022 100 100 000 Old_age Always - 1

Was someone dealing with similar issue ? |

As I can see no one knows what does it mean  ok anyway here is some new progress on the disk status.
After a long time there have been found some new pending sectors so here is the smartctl output:

so now I see some sector which seems to be bad, but as we can see on output from fdisk:
| Code: | fdisk -lu /dev/hda
Disk /dev/hda: 164.6 GB, 164696555520 bytes
255 heads, 63 sectors/track, 20023 cylinders, total 321672960 sectors
Units = sectors of 1 * 512 = 512 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/hda1 63 208844 104391 fd Linux raid autodetect
/dev/hda2 208845 321669494 160730325 fd Linux raid autodetect
|
the /dev/hda2 ends on sector 321669494 but the bad sector is 321669951 which seems to be in spare area??
I have there LVM volumes on software raid1 and it doesn't seems that the block is used at all, because not all diskspace is used yet.
I would appreciate any suggestions as it definitely looks very weird
Thanks for replies. |
