March 2, 20197 yr I noticed my unraid OS version was a bit old so I went to update it, however, there was no button available to update the OS in the listed plug-ins so after a little searching I found the URL to upgrade to 6.6.7, which seemed to go OK. But then it asked me to reboot to complete the update. I shut down the array and rebooted. After the reboot I got quite a few drives resulting in CRC Errors. They were working fine before under the old OS? I have 5 data drives, one parity, and one cache drive. The cache drive resulted in 1 CRC Error. One data drive resulted in 12 UDMA CRC Errors and another data drive resulted in 194 UDMA CRC Errors. What do people typically do in these situations? Should I just monitor the drives to see if the CRC Errors increase or is critical enough to replace these drives now? Again, the odd thing is that all of these drives reported no issues on the former version of unraid so this came as a surprise.
March 2, 20197 yr Older Unraid releases, pre 6.4 IIRC, didn't monitor CRC errors, now it does, just acknowledge current values and as long as they don't keep increasing you're fine, if they do it's likely a bad SATA cable.
