[Solved]disk DSBL, ok after rebuild, happened multiple times

Hi,

 

unRAID Version: 4.7

 

For the 2nd time yesterday one of my disks had the red ball and was marked as disabled. checking the syslog I saw that a write failed. The first time it happened a few weeks ago, I checked all connections and re-added the same drive and rebuilt parity. Checking smart values everything looked ok. Working great since then, now I have the same problem. The problem seem to relate to the install of a SuperMicro AOC-SASLP-MV8 to add more drives. Currently I have 4 drives connected to this controller but both times it was the same drive, drive 7.

 

In the syslog I see some weird stuff, that I cant really identify. It looks like the SuperMicro has a problem, but why only every few weeks? Ps: I replaced the serial ATA breakout cable with a new one already.

 

Additional hardware info:

Mobo: ASUS M4A78T-M

PSU: CORSAIR CMPSU-400CX 400W

CPU: AMD Sempron 140

Memory: 8GB Kingston ValueRAM DDR3 133 (PC3 10600)

9 2T drives plus 1 spare online, plus 160GB cache drive

 

any help appreciated, rebuilt currently in progress and array is up :)

Hi,

 

yes, rebuilding finishes without a problem and now all drives are green and happy again.

 

Here is the smart report of the drive

I thought about the PSU. But with no problems whatsoever during multiple parity checks and this rebuilt, it doesn't seem probable. MyMain - smart view doesnt show anything except green.

 

Update: just tried spinning up and down all drives while writing a large file to the disk to see if there is any impact, but no problem

and it happened again ... :( I guess I am going to try a bigger PSU. Maybe with the additional card, drives and memory 400W isnt simply sufficient. I see the seasonics get good reviews. would a SeaSonic X Series X650 Gold be sufficient and work with my Mobo: ASUS M4A78T-M in a cooler master centurion 590?

noticed, that I never resolved this topic. So, better late than never: I'm happy to report, that the new PSU: SeaSonic X Series X650 Gold did the trick. No problem since! :)

 

 

ps: strangely I can't modify the original post. no 'modify' option. Obviously I could change this reply but not the orig. So mods fell free to add [solved] to the title. cheers
