October 8, 20178 yr Hi, having Big trouble here... My server started going crazy last week so I returned parity disk to seller and replaced with new one,. After setting the new disk everything seem fine, started parity check and finished OK, then after a few hours I had problems with this disk: same results, parity data errors, disk in read only mode and array stopped.

October 9, 20178 yr FYI you posted on the wrong forum, this one is for bug reports, in the future use the general support forum. Now for your actual problem, please post the complete diagnostics (Tools -> Diagnostics), it includes much more info, like SMART reports, etc.
October 9, 20178 yr Author So anyone can put this post to the right place ? Thanks. In the meantime, here's other data... towerfu_backup-diagnostics-20171009-1840.zip towerfu_backup-smart-20171009-1838.zip Edited October 9, 20178 yr by ffurlanut
October 9, 20178 yr SMART for parity disk looks fine but there are already 7 UDMA CRC errors, these suggest a bad SATA cable, replace it and re-sync parity. Before or after that, do it before if you need to access your data, you also need to check file system on disk1 (md1): https://wiki.lime-technology.com/Check_Disk_Filesystems#Drives_formatted_with_ReiserFS_using_unRAID_v5_or_later
