really slow parity rebuild

Featured Replies

Hi all,

Had a really not old drive go down today, bit suss, threw another spare drive in just cause I had one and the rebuild speed is really slow (400kb/s). I suspect there is a problem is cabling but dont know how to even start reading the diogs. Attached them below, grateful for any help

Looks more like a controller problem, controllers with SATA port multipliers are not recommended.

  • Author

Sorry not real up with the names of things, you mean the sata port cards?

 

  • Author

The card  you put in the PC-i slots?

 

  • Author

OK so I have taken the new sata card out and started everything back up and the rebuild is happening much faster but now have the #3 disk being 'Unmountable: wrong or no file system" as well as the #1 disk showing the same. #3 was the only 'new' drive. Diogs attached

Yes, and you are still using it in the last diags, see here for some recommended models, only one you've replaced that you should attempt the new rebuild.

ok thanks again for the help

  • Community Expert

Yes, should be.

  • Author

thanks mate, hopefully this has been the root of my problems👍

  • Community Expert

You will likely still have to deal with the unmountable disks, but you want to do that with the new controller, post new diags after array start once you have it.

  • Author

New card put in and I got the disc mounted again but something still not right, I have backups of all the data so don't care about losing anything. Everything just seems to be struggling??

That's a Marvell controller, not the Asmedia linked above, those are not recommended with Unraid, but the problem currently appears limited to disk1, try replacing/swapping cables for that disk.

Um ok, it was the card I linked to but ok?? Not really sure how I'm supposed to tell the difference bot I'll try the cable

The one you have is a Marvel 9215, not Asmedia ASM1064

OK thanks I'll deal with them shortly👍

  • Author

Appreciate the continuing support, must be annoying the crap out of you. Cable doesn't seemed to have done anything. Parity check is still struggling

  • Community Expert

No ATA errors so far, but there are checksum errors, so good idea to run a memtest.

  • Author

Went thru the first pass with no errors, but I'll let it go until after work tomorrow

  • Author

memtest went all ok, I'm not sure but I think it might have been the actual disk itself, started to hear it 'clicking' so replaced it with another older drive that I had laying around and so far the rebuild is sailing along sweet as. Guess I'll find out

  • Community Expert

Looks good for now.

  • Community Expert

That's a SAS expander, it's a good option for many disks but it requires a separate HBA, like an LSI 9211-8i for example.
