Qiou Posted December 10, 2021 Share Posted December 10, 2021 Hey fellow Unraiders I've bough 3*12TB in order to replace my 1*4TB and 1*3TB drives Now the setup is 1*12TB as parity (already in place and set up) 2*12TB cleared and added to the array 1*3TB and 1*4TB which are already in place Now it's time to move files between disks in order to be able to remove the previous disks I know the question may have been asked abnout how to transfer files between disk (and not Shares). I've found multiple answer but not a clear one of a recent one I found Unbalance quite reliable in the past, I'm planning to use it, but today transfer speed are really slow, like 9-12MB/s I've disabled parity to help with preventing writing to it, I'll redo the parity once done Any suggestions ? Thanks in advance Quote Link to comment
trurl Posted December 10, 2021 Share Posted December 10, 2021 It would have made a lot more sense to just replace the smaller disks with the larger, one at a time, and let it rebuild. 24 minutes ago, Qiou said: transfer speed are really slow, like 9-12MB/s I've disabled parity to help with preventing writing to it attach diagnostics to your NEXT post in this thread.

Qiou Posted December 10, 2021 Author Share Posted December 10, 2021 (edited) @trurl I've attached diagnostics here kirito-diagnostics-20211210-2120.zip So I can rebuild the drives onto larger ones ? That could work for me, I'll move files back, rebuild the parity and find out how to rebuild on a new drive Edited December 10, 2021 by Qiou Quote Link to comment
Qiou Posted December 10, 2021 Author Share Posted December 10, 2021 Another useful info: One of the three 12TB drives is performing way faster than the 2 others. I may have it a limitation of my motherboard ? I'll let the parity rebuild on this drive first and get back on why the 2 others are performing way slower Quote Link to comment
trurl Posted December 10, 2021 Share Posted December 10, 2021 Disk1 is CMR and disk2 is SMR, which can perform slower than CMR. Not obvious about the others without looking up the models since their SMART report doesn't specify. Quote Link to comment
Qiou Posted December 10, 2021 Author Share Posted December 10, 2021 Other models are Western Digital White Label 12TB, freshed shucked from 3 My Book units (identical) Quote Link to comment
Qiou Posted December 11, 2021 Author Share Posted December 11, 2021 @trurl It's been now 24h and my array only managed to rebuild 1.59TB of Parity, despite numerous run at 110/120MB/s the days before I don't see any errors on disk Smart results, cables are the same as before, the parity checks on 12/09 and 12/10 were both on the 12TB drive Only change I had to do was cutting the 3.3V rail to power the 12TB drives, because they refused to boot otherwise Quote Link to comment
Qiou Posted December 12, 2021 Author Share Posted December 12, 2021 I think I've found the culprit here: root@Kirito:~# dd if=/dev/sdc of=/dev/null bs=4k status=progress 3133599744 bytes (3.1 GB, 2.9 GiB) copied, 16 s, 196 MB/s^C 802639+0 records in 802638+0 records out 3287605248 bytes (3.3 GB, 3.1 GiB) copied, 16.7633 s, 196 MB/s root@Kirito:~# dd if=/dev/sdb of=/dev/null bs=4k status=progress 275914752 bytes (276 MB, 263 MiB) copied, 15 s, 18.8 MB/s^C 67394+0 records in 67393+0 records out 276041728 bytes (276 MB, 263 MiB) copied, 15.1245 s, 18.3 MB/s root@Kirito:~# dd if=/dev/sdd of=/dev/null bs=4k status=progress 4916891648 bytes (4.9 GB, 4.6 GiB) copied, 16 s, 307 MB/s^C 1204285+0 records in 1204284+0 records out 4932747264 bytes (4.9 GB, 4.6 GiB) copied, 16.0833 s, 307 MB/s sdb is my 3TB drive, maybe it's becoming to fail, unsure why now though new diagnotics attached kirito-diagnostics-20211212-0315.zip Quote Link to comment
trurl Posted December 12, 2021 Share Posted December 12, 2021 SMART for that disk looks OK but it hasn't had extended test done recently. You might need to disable spindown on the disk to get extended test to complete. Quote Link to comment
