Disk showed up briefly as "unformatted" and Error during Parity check

Featured Replies

Last night, I upgraded to version 4.3.1 from 4.3.beta6

 

Everything went fine, UNRAID started without any problems.

 

Then, I finally implemented the custom timezone feature and did a "reboot" of UNRAID. When it came back up, the last disk that I added a Smasung 750 GB disk, showed up as "unformatted". This is a brand new disk and I had replaced an old disk with this new one. During that replace, UNRAID did a rebuild and re-created data on this disk (I do not remember it going through a format process).

 

That worried me and I decided to restart the array.I stopped it and started it and this time the disk showed up the way it was before. Anyway, I decided to do a parity check again and then went to sleep. When I woke up, it had completed, but showed that there was one error during parity check.

 

I went through the syslog, but did not see any thing that would be cause to worry, but, I am not sure. Can someone take a look and see if everythings OK and If I need to do some preventive action.

 

I have attached the syslog and a screenshot of the main page. I have also run "smartctl -a" on the disks and if needed I can attach them.

 

Thanks,

This is normal, there is no need to format a disk when it is being used to replace an existing disk since the contents (and the formatting) of the existing disk will bring over the formatting.

You are probably just fine.  I would do another parity check just to be sure it is not a disk that is acting up.  Then another set of smartctl on the disks will show if the process is detecting any bad sectors.

Thanks! I will do what you have suggest tonight and keep you posted on the results.

See this post.  There are several reports like yours, of a drive unexpectedly showing as Unformatted, and a shutdown and restart seemed to clear it up.

 

You either have exceptionally good cooling, or a faulty temp sensor on the CPU, or an incompatible sensor driver.  The CPU temp shows as -269C in the line below!

Tower kernel: ACPI: Thermal Zone [THRM] (-269 C)

I'm curious what kind of cooler you have on that CPU!  It's not an important issue, but it might be interesting on your next reboot to check the BIOS menus for a PC Health menu that shows the CPU temp.

 

The parity error occurs very early in the check, so was probably due to the one drive appearing temporarily to be unformatted.  Should be harmless.

Robj,

 

I do not have any special CPU cooler. I used the one that I got when I bought the intel CPU.

It's OK, just my poor attempt to be facetious.  You would need a very expensive liquid nitrogen or better cooler to achieve -269C.

-279C would even be more impressive.  I think if that happens you'll actually go back in time.

I re-ran the parity check and it came back successful without any errors.

 

I also re-ran smartctl on my 3 disks. The 300 GB (seagate) one seems to have high read and seek error rate, but the document on SMART says that these values may be high for Seagate disks. I haven't had any problem with the disk.

 

ID# ATTRIBUTE_NAME          FLAG    VALUE WORST THRESH TYPE      UPDATED  WHEN_FAILED RAW_VALUE

  1 Raw_Read_Error_Rate    0x000f  102  094  006    Pre-fail  Always      -      76601297

7 Seek_Error_Rate        0x000f  086  060  030    Pre-fail  Always      -      467332648

 

At this time, I think this was just a one time occurrence and will just ignore it and continue.

 

Thanks!
