Extremely slow Drive Rebuild after M1015 Install (<5MB/s)

Featured Replies

Guys, finally installed a new M1015 after having issues with the first one I purchased and everything boots fine. I'm trying to rebuild a red-balled disk and the rebuild is going very slow.  I couldn't rebuild on my old card because the drives would randomly drop from the array.

 

Here's the syslog, I have no idea how to troubleshoot this.

Are you using hotswap bays?

 

I would check the cabling to the drives / bays and the power (your supply could be undersized, getting weak, etc)

  • Author

No hotswap bays. 

 

Would cables suddenly go bad if I've been using them for 4 years without touching it?  The problem is very frustrating, considering that I waited so long to get this adapter card working, lol.  I'll just buy a new set of SATA cables and see if that works.

 

I upgraded the Power Supply fairly recently because I had an issue of drives being dropped.  Once I replaced the Power, everything was fine again until these crop of issues.

 

Syslog attached.  Thanks for all the help (as usual).

Without hotswap bays, the odds of you inadvertently touching them (and knocking them around) are pretty good when you replace the power supply feeds to the drives.

Yes, you're right but I recabled everything after I replaced the Power Supply using the same connectors.

 

I might have a few lying around, I'll try replacing ones that look stressed (some of the 90 degree cables).

To my mind, it still looks like either your breakout cable or the power cable.  But, I don't have an M1015 so I can't say for sure.  I suppose it could be the drive itself.  Whats the smart report look like for SAMSUNG_HD204UI_S2H7JD2ZB04607

smart.txt

Looks good.  No attributes near their threshholds, and no errors logged.  Looks like cable and/or supply

Ok, I'll try swapping cables around.

 

unRAID remembers the drive position via Serial Number, right?  So it won't matter if I swap actual cable positions, correct?  I remember reading somewhere that this is how it works but would like clarification before I remove all SATA cables.

That is correct on 5.x+.  If you swap the breakout on the samsung with another drive we will see if the problem stays with the drive or moves to another one.

This is an old topic, but the issue was the M1015 card I was using, it would begin to slow down after attaching more than 2 drives to it.  This issue occurred on my old build and my new one I setup a year ago (and added the old M1015 2 months ago). Not sure if it was a firmware issue or not, but I'm using a different card now (as of this week, years later) and no longer suffer from this issue. 

Just FYI to anyone who has the same issue.
