November 17, 20241 yr Four data, One parity drive. Started getting SMART errors on my drives so I am going to replace them all, 4TB to 6TB. Parity went no problem (4 to 6tb), 16 hours and done. Now replacing one of the SMART error data drives and it's currently at 66KB/s so it should be done in about a year. I have switched drives, cables, and SATA ports, the same result: starts fast (100mb/s+) then slows down to a trickle. I obviously can't wait for a year for the drive to rebuild, and I cant replace other drives until this one is done. What can I do besides scrap the data and start all over? Diagnostics attached, would appreciate some help. tower-diagnostics-20241117-1717.zip
November 17, 20241 yr You might try adding the disks as a standalone disk(after preclearing them) and copy data over to them. Then scrap the array, add in the new disks and start building a new parity It also really helps disable docker when building a new drive is that's the way you want to go about it
