I initiated a parity check before I was planning to add another drive to the unRAID server, but it never finished the parity check and noticed a strange error in the syslog file. After this the media is not available but I can access the flash drive. I have search the forum for this but I have only found one post with it but that post was never answered. Everything was running fine before. I restarted the machine and got to 64% done with the parity check with only 2 hours to go, then it spiked to 15 days to finished, then I noticed the kernel bug again.
I am on unRAID v4.5.6
I am attaching the complete syslog and below is the specific issue I am seeing:
