sbap Posted February 27 Share Posted February 27 (edited) I have an array with 4 drive 1 Parity with 8TB and 3 data drives with 4TB. I stopped the array, shut down the server, replaced the 1 of the data drives with a 8TB drive. I started the array, which started the rebuild process, checking 24 hours later it was only at 33% the speed was under 100KB/sec. I tried different thing, pausing and starting the rebuild process. When Cancelling it and rebooting the system to start again it already starts in with under 100KB/s and the speed is not picking up. attache the the Diagnostic file. What could be the issue? tower_ii-diagnostics-20240227-0722.zip Edited February 27 by sbap attached correct file Quote Link to comment
itimpi Posted February 27 Share Posted February 27 We would need diagnostics taken while you are experiencing the problem. The ones posted look like just after a reboot. Guessing, I would think the most likely issues are the SATA and/or power cabling causing tone o more drives to be continually resetting. Quote Link to comment

JorgeB Posted February 27 Share Posted February 27 Could be an issue with disk2, it's not giving a complete SMART report, post new diags. Quote Link to comment

Even those diagnostics do not seem to be while showing the problem as the last line in the syslog is the parity check stating. Quote Link to comment
Solution sbap Posted February 28 Author Solution Share Posted February 28 In the meantime I replaced the drive with another drive and the data-rebuild went through without issues. I assume an issue with the drive will test it seperatly. Quote Link to comment
