Hi all,

I've got a fairly old system which has been working reliably for a long 
time, and I've become somewhat lazy in maintaining it, but since it's 
still in production, and rather important, I figured it was time for a 
checkup while I'm basically confined.

I have run a raid check, and these are the logs from the system:

[11243683.671268] md: data-check of RAID array md1
[11243683.671305] md: minimum _guaranteed_  speed: 1000 KB/sec/disk.
[11243683.671339] md: using maximum available idle IO bandwidth (but not 
more than 200000 KB/sec) for data-check.
[11243683.671417] md: using 128k window, over a total of 3867693056k.

The rest of the log is included below, but it repeats with errors for 
both sdd and sdf, but all other drives are not mentioned.

Is there a method to determine if this is a HDD error (ie, 2 drives that 
have errors) or a cabling issue (with just these two drives) or some 
strange driver/motherboard issue?

I notice in the output below MD is showing a number of bad blocks on the 
drives, and logs suggest that the drives have run out of "spare" space 
to re-allocate these to.

Is there some test I could run on the drive itself to narrow down the 
issue?

Should I replace one of these drives with the spare?

Is there some method to check the status of the spare to ensure it is 
working properly?

Any other suggestions?

just try by start with the cheapest option: cables

when nothing changes switch where they disks are connected and you will
find out it's the motherboard when suddenly one drive that was completly
fine before has the same issue

from the moment on some software stack is telling you about bad blocks
on drives run fast and replace fast

This disk has a pretty high count of reallocated sectors, plus a lot
of other errors.  I recommend to replace it ASAP.  It is not worth
further investigation - this drive has reached EOL.

This disk also has stored a number of errors, but it does not look
as bad as the first one.  However, there are errors.  I would
replace it as well.

Concur.  Old and worn out.  Personally, I replace when reallocations are 
in the 10 to 20 range.  Once you get past that, they seem to start 
coming much faster.

Disagree.  No reallocations by the drive, just bad block log entries. 
This drive is fine.  The bad block log mis-feature should be turned off 
after failing this drive, zeroing its superblock, and adding back to the 
array (so the bad blocks get reconstructed).

The bad block log mis-feature should never have been merged in its 
current form--it simply prevents redundancy from ever working on problem 
sectors, and cannot distinguish correctable communications problems from 
true underlying uncorrectable sectors.  Which should be left to the 
drive, at least until it runs out of spare sectors.  (And why would you 
keep such a drive anyways?) Bad block logging in MD raid is *Dangerous* 
*Junk*.

Thank you, I'll check if the drive can be replaced by warranty, or else 
check if I have a spare. Otherwise, I may be forced to buy a replacement.

So I have a "spare" drive in the array, what steps should I take to 
"fix" this? Here are the statistics on the spare drive. Maybe it is just 
as bad as the other two anyway, and I should replace all three?

If I can, I assume I would run some commands on the spare to configure 
it to not have any BBL, then add it back to the array, use it to replace 
the existing bad drive?

I assume that the two "good" drives and mdadm output, suggests that I 
have a single "good" copy of all the data on the two good drives:

     Number   Major   Minor   RaidDevice State
        0       8       18        0      active sync set-A /dev/sdb2
        1       8       34        1      active sync set-B /dev/sdc2
        2       8       50        2      active sync set-A /dev/sdd2
        4       8       82        3      active sync set-B /dev/sdf2

        3       8       66        -      spare   /dev/sde2

(Good drives assumed to be sdb and sdc)

Equally, all data is real-time synced to another machine (DRBD), as well 
as being backed up regularly, so I'm not super concerned about the data 
content, but I do want to maximise uptime, and minimise risk to the data 
as it really is rather important (understatement...).

Note, parts were omitted, hopefully I've included the relevant/important

I'll be astonished if you can get a warranty replacement for a drive 
that has 60 *thousand* hours of uptime.

Use the --replace operation of modern mdadm/kernel to get that failing 
drive out right away.  It appears you won't be able to remove the bad 
block misfeature until all devices in the array have an empty log.

Understood.  --replace is your friend.

Bleh.  Replace this one, too.

These two are in astonishingly good condition for their age.

When you've replaced the two bad drives and returned to having a hot 
spare, use --replace again on any drives that still have entries in 
their bad block logs.  The free up drive can than have its superblock 
zeroed and added back as the spare.  Rinse and repeat.

All of the above can be done on the fly, assuming you have hot-swap bays 
for new drives.

When all drives are good, with empty bad block lists, stop the array and 
immediately re-assemble with --update=no-bbl.

Hear hear!  When the drive is saying it's not happy... go get some
more now.  I wouldn't even question the badblocks you're seeing, that
means it's dying.
