November 18, 20205 yr Community Expert Your syslog shows that you are getting lots of read errors on disk2 and it is regularly re-setting. It is not clear to me disk2 has dropped offline or has some other sort of problem (e.g. cabling).
November 18, 20205 yr Community Expert Replace it, if you need to recover data and since parity isn't valid best bet is to use ddrescue.
