  1. added additional nvme drive now sata array blowing up with udma crc error count

    af22 replied to af22's topic in General Support
    I'm embarrassed to report back that it may have been a loose sata cable. One of the drives (parity2) reached 22,831 udma crc errors and Unraid failed the drive. I went to inspect the cable on that drive and it looked a bit loose. I'm about 12 hours in a parity check and it's been fine.

  3. added additional nvme drive now sata array blowing up with udma crc error count

    I just added an additional 2tb nvme WD Black SN850X to my machine and now my sata array is blowing up with "udma crc error count". I've spent the last 4 days replacing my four 4tb drives with new 12tb drives. Each drive took about 24 hours to finish parity, not a single "udma crc error" appeared. Then I added the new nvme and now i'm getting email alerts. I've read through the posts about "udma crc error count" and they all point to a faulty cable. But i just started getting the error on 4/8 of my drives after adding the nvme and running a parity check. How can a faulty cable affect 4 drives? I've had this machine running for 2.5 years without an issue. Ryzen 5950x on X570 mobo: 1. 12tb - parity1 2. 12tb - parity2 <---- udma crc error count 10011 3. 4tb - disk1 4. 4tb - disk2 <---- udma crc error count 1 5. 4tb - disk3 <---- udma crc error count 1 6. 12tb - disk5 <---- udma crc error count 1 7. 12tb - disk6 8. 4tb - mounted disk nvme1: 2tb samsung 980 pro - cache nvme2: 2tb wd black sn850x - media_cache <---- new drive Could a bad cable on the parity2 drive cause crc errors on the other 3 data disks? My bios is from 2021. Is it possible the new NVME drive is causing compatibility problems and maybe if i update the bios it will help? I can remove the new NVME drive and test again. Wanted to see if i'm missing anything?

    Wouldn't you eventually need to TRIM the ssd's eventually, when the drives start to slow down?

  5. Is it safe to upgrade 1/2 parity drive + 1 data drive at the same time?

    af22 posted a topic in General Support
    I currently want to upgrade 2 of my drives to larger 12tb (parity and data drive). Instead of replacing one drive at a time and letting parity rebuild twice, would it be safe to replace 2 drives at the same time because I have 2 parity drives? Current Array: 1. 4TB Parity1 -> upgrade to 12tb 2. 12TB Parity2 3. 4TB data1 4. 4TB data2 5. 4TB data3 6. 2TB data4 7. 2TB data5 -> upgrade to 12tb
