You have a disk with S.M.A.R.T problems, serial Z4Z2JY5V. Probably it got dropped by the hard disk controller when you started a preclear session. The only way to be sure is to run Preclear again and, if it fails, share your Diagnostics file here (at Tools menu of your server).

Two other devices dropped offline:

Apr 25 19:47:52 unraid kernel: ata16: SATA link down (SStatus 0 SControl 300)
Apr 25 19:47:57 unraid kernel: ata16: hard resetting link
Apr 25 19:47:58 unraid kernel: ata8: SATA link down (SStatus 0 SControl 300)
Apr 25 19:47:58 unraid kernel: ata8.00: disabled
Apr 25 19:47:58 unraid kernel: ata16: SATA link down (SStatus 0 SControl 300)
Apr 25 19:47:58 unraid kernel: ata16.00: disabled

 

You're using a 6 or 10 port controller that is in fact a 2 port controller with SATA port multipliers, these controllers are a known source of multiple issues, it should be replaced.

An LSI megaRAID controller is not the best option for Unraid, an LSI based HBA would be best, still better than the one you were using before.
