Neostim Posted April 14, 2018 Share Posted April 14, 2018 I'm on the trial of unRaid, I've got 6 data drives and 1 parity drive, all 2TB or 1TB in size, I'm seeing about 8-19MB/sec on parity creation, currently 2 days and 10 hours to finish. I can't seem to cancel parity to try swapping in a different 2TB drive in case it's the drive, is there any way I could sanity check this drive in unraid to eliminate that as a possibility? SMART status isn't exactly working with my 3Ware 9650SE-24M8 so even if it was having issues I'm not sure I would know. Quote Link to comment

Neostim Posted April 14, 2018 Author Share Posted April 14, 2018 (edited) Reading through this handy diagnostics file I see the following, maybe this is the cause of my issues, read errors on one of the data drives: Apr 14 17:00:44 Tower kernel: 3w-9xxx: scsi5: ERROR: (0x03:0x0202): Drive ECC error:port=19.

Maybe you know this but you will have to set a New Config to remove a drive from the array. Tools - New Config, Retain All, then unassign the disk to be removed. Don't check parity is valid, then start the array to begin parity sync. Quote Link to comment
Neostim Posted April 14, 2018 Author Share Posted April 14, 2018 Thanks! That helped, I've dropped the "bad" disk from the array now, parity still at 8mb/sec currently Quote Link to comment

JorgeB Posted April 15, 2018 Share Posted April 15, 2018 06:00.0 RAID bus controller [0104]: 3ware Inc 9650SE SATA-II RAID PCIe [13c1:1004] (rev 01) This is not a recommended controller and I'm pretty sure other users also had very poor performance with it. Quote Link to comment
