Server Becomes Slows and Unresponsive


Recommended Posts

I recently upgraded to rc8a and was unable to get the network working so I can had to use what someone else linked: http://lime-technology.com/forum/index.php?topic=22615.0 https://dl.dropbox.com/u/49442039/unraid-rc8a-media-tree-2.zip I'm not really asking for help to resolve my current issues but I'm wondering if it would be possible to format my flash drive and set up a "stable" beta/rc.  If I did this would it be able to bring it up with the same /mnt/user/ that exists right now?  And if so what would be the latest and most stable version of unraid to install that would maintain my files?

Decided I'd check my disks since I noticed some errors on my last parity sync, so finally managed to get the array to stop and get a clean shutdown and noticed some irregularities on the smart report on my parity disk, any thoughts?

After looking at the Reallocated sector count, Current pending sector count, Current pending sector count and Offline Uncorrectable count, if it were my server, I would either shutdown the server completely or not permit any application to write to the array until I had replaced that parity drive and had rebuilt parity!

Thanks, thats what I was afraid of.  I decided to run reports on all my drives and they are all showing the same values, I'm assuming I need to replace them all after rebuilding the parity drive?

You are looking at the wrong columns in the table.  You should be looking at the Raw_value at the extreme right of each line.

 

By the way, if you look up S.M.A.R.T. on Wikipedia, you will find a description of what everything is all about.  In fact, it provides you with a listing of Attributes that are important in determining the health of a drive..

These values are fine. The VALUE of the entries is 200 (perfect) if the VALUEs drop to the TRESH number (0) then the drive has failed. Most of the RAW values have meaning only to the manufacturers. The Reallocated_Sector_Ct and Current_Pending_Sector RAW values indicate bad or questionable sectors. UnRAID requires that there be zero Pending sectors in order to operate correctly. UDMA_CRC_Error_Count results from a bad, loose, or poorly routed SATA cable (too close to a power line), or a bad SATA port or card. As long as Reallocated_Sector_Ct (and UDMA_CRC_Error_Count) are not increasing then the drive (and drive connection) is fine.

 

Only the parity drive needs to be replaced.
