Hey,

i found the following lines in my logfiles:

Code:
Jan 12 01:12:07 irulan smartd[1815]: Device: /dev/hda, SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 64 to 65
Jan 12 01:12:07 irulan smartd[1815]: Device: /dev/hda, SMART Usage Attribute: 195 Hardware_ECC_Recovered changed from 64 to 65
Jan 12 02:12:07 irulan smartd[1815]: Device: /dev/hdc, SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 58 to 57
Jan 12 02:12:07 irulan smartd[1815]: Device: /dev/hdc, SMART Usage Attribute: 195 Hardware_ECC_Recovered changed from 58 to 57
Jan 12 03:12:07 irulan smartd[1815]: Device: /dev/hda, SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 65 to 64


I tried to find out wether that's good or bad. At the moment i'm still not sure, maybe someone of you can help?

smartctl -A shows:

both harddiscs are the same; here's hdparm -i:

Code:

why udma4 if it could run at udma5? In fact hdc is running in udma5, while hda is running in udma4. I don't know why, in my syslog i got the following:

Code:

no failure so far.. after turning the raid on and mounting it, i get:

Code:

raid1: raid set md0 active with 2 out of 2 mirrors
md: ... autorun DONE.
kjournald starting.  Commit interval 5 seconds
EXT3-fs: mounted filesystem with ordered data mode.
VFS: Mounted root (ext3 filesystem) readonly.

hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
ide: failed opcode was: unknown
hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hda: dma_intr: error=0x84 { DriveStatusError BadCRC }

hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
ide: failed opcode was: unknown
ide0: reset: success
EXT3 FS on hda7, internal journal


so as you can see it's starting with udma5 - at the point while or before mounting hda7 it's disabling DMA and switching to udma4 - if i try to manually change that with hdparm i get the same errors again in dmesg and it's automatically changing again to udma4.

The harddisc(s) are running pretty fine. Anyway. If i go on them with e2fsck (Read only) i get the following:

root partition - hda7
Code:

Pass 1: Checking inodes, blocks, and sizes
Deleted inode 1224228 has zero dtime.  Fix? no

/usr - hda5
Code:

Pass 4: Checking reference counts
Pass 5: Checking group summary information

Fix? no


hdc7 (not in use atm)
Code:

Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
/lost+found not found.  Create? no

Pass 4: Checking reference counts
Pass 5: Checking group summary information
Free blocks count wrong (619015, counted=1070784).
Fix? no

Free inodes count wrong (521339, counted=611636).
Fix? no


i checked the raid device, too, there are no filesystem errors. so i'm not seeing anything 'critical'.

Someone any idea on this? I mean - is the harddisc broken, should i replace it, will the harddisc die in a few weeks (i have that errors now a while and nothing happened), is this behavior correctable and maybe chipset/kernel related... ANY ideas?

smartctl --test=long /dev/hda
Code:

# 1  Extended offline    Completed without error       00%      9158         -
# 2  Extended offline    Aborted by host               90%      9157         -
# 3  Short offline       Completed without error       00%      5208         -


the # 2 is there, because i aborted the check, anyway, as you can see, here's no problem, too.

jfyi

el_angelo mentioned that it could be the chipset. He had similar problems for 2 years and nothing happened. So it could be 'safe' (more or less) to just ignore this "errors"

Anyway.
