May 1, 20233 yr Hey, last month I replaced two of my disks because I was getting errors on them and I thought they were dying. But now, two weeks after the last replacement, I am getting errors on a third disk. So I'm not sure if it's a disk problem anymore. Is it normal to have three disks fail in such a short period? This setup has been working for the last year or two without problems. I have attached the latest diagnostics report after the error. Could someone take a look? Is it a dead disk, or should I be looking at something else, like the PSU, cables, or memory? And is it safe to keep my array stopped in this state or should I turn off the server completely till everything is fixed? Thanks! diagnostics-20230501-1018.zip Edited May 1, 20233 yr by Rhonin
May 1, 20233 yr Community Expert Start by updating the LSI to the latest firmware since the one you are using has known issues, could also be a power/connection issue.
May 3, 20233 yr Author Thanks for the quick help! I updated the LSI to version 20.00.07.00, and I also replaced my old be quiet! PSU with a Corsair RM850. I then successfully rebuilt the affected disk and performed a parity check. However, during the parity check, the "udma crc error count" on another disk increased from 0 to 25. Should I be worried about this? What could be the reason for it? Could it be the SATA connections? I have ordered new SAS to SATA cables that should arrive this weekend, and I plan on replacing them then. Is there anything else that could cause "udma crc errors"? Thank you in advance! diagnostics-20230503-1850.zip
