Timeout error, disk gone

Timeout error, disk gone

[Matthias Urlichs]

Does anybody have an idea what this could mean:

> ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen
> ata2.00: (BMDMA stat 0x61)
> ata2.00: tag 0 cmd 0x35 Emask 0x4 stat 0x40 err 0x0 (timeout)
> ata2: port failed to respond (30sec)
> ata2: Soft resetting port
> ATA: abnormal status 0xD0 on port 0x30C7

The disk didn't react any more until I cycled the power.
SMART state doesn't admit that anything could amiss.

Transient glitch? Major ugliness? For the time being I have not re-added
the thing to my RAID, but the three other disks in it are the exact same
model...

What model and what firmware ? There are some problem firmware releases
around with older SATA drives

Samsung SP2004C, firmware version unknown -- how do I find out?

It is all right to hold a conversation, but you should let go of it now
and then.

Please post the result of 'lspci -nn' and full boot log.  Samsung
firmwares tend to be pretty good but I've seen earlier ones occasionally
lock up after certain PHY events.  Removing power and reapplying puts it
back into sane state.

Oh and I'm pretty sure it was the drive which locked up.  If you connect
the harddrive to different working port without removing power, the same
timeouts happen while the original port detects and works fine with
another hotplugged drive.  And for the record, among the earlier SATA
drives, samsung ones were definitely in the better group.

Also, please include full log of failure.  Thanks.

Not this one, as reported in my earlier mail -- unless you redefine "sane".

I'll try to elucidate something from it after it's replaced.

When the polls are overwhelmingly unfavorable, (a) ridicule and dismiss them
or (b) stress the volatility of public opinion.

Its in the identify data, however I'm not aware of any problem Samsung
drives in reports so far.

Looks like a hardware problem. After a hard powerdown got it
recognizable again, it now manages to have a read speed of 1/2 MB/sec --
as opposed to its three brethren which are approx. 111 times faster.
