ladlo Posted April 3, 2020 Share Posted April 3, 2020 (edited) Hello!, I've been using unRaid from a few years ago and replaced two failed drives before, everithing went smoothly. A few days ago my parity drive failed, bought a replacement (4Tb seagate ironwolf), succesfully precleared it, and started the sync/rebuild... Now I've got an 25 days estimation till completion. I've searched "slow rebuild" in the forums, but all solutions seemed related to slow drives... How can identify if one of my drives is causing this extreme slowdown?. Should i try to stop and reboot the system? I don't know if that can be dangerous since the rebuild has started... In previous rebuilds invested eight, sixteen hours on the worst case, but this is freaking me a little since my data is already unprotected... The diagnostics are attached to this post, thank you in advance for any feedback and sorry for my horrible english tower-diagnostics-20200403-1719.zip Edited April 3, 2020 by ladlo Quote Link to comment
JorgeB Posted April 3, 2020 Share Posted April 3, 2020 According to the diags it's completely stalled, there's an ATA error for disk1, and it's not reporting SMART data, power down, check/replace cables on disk1 and try again. 1 Quote Link to comment
ladlo Posted April 3, 2020 Author Share Posted April 3, 2020 Thank you very much johnnie.black ! Re-seated cables, rebooted and it now marks 9-10h for the rebuild. Still got a warning about one 2tb drive though... Could it "inherited" be from the previous fault state? Attached the diagnostics from this fresh boot tower-diagnostics-20200403-1800.zip Quote Link to comment
JorgeB Posted April 3, 2020 Share Posted April 3, 2020 With a little luck parity sync will finish without error, but disk1 should be then replaced ASAP. 1 Quote Link to comment
ladlo Posted April 3, 2020 Author Share Posted April 3, 2020 I'll keep my fingers crossed and follow your advice, I'll replace the drive as soon as posible... probably replace all the SATA cables in the system too for good measure. Quote Link to comment

ladlo Posted April 4, 2020 Author Share Posted April 4, 2020 Parity finished withouth error, lots of thanks for the help. Now doing a extended SMART Test and a few preclear rounds on a 3Tb drive to replace the Toshiba. All drives marked healthy on the dashboard though. Is that normal?, only asking in order to do SMART tests regularly if that screen is a simplification of the health state... Quote Link to comment

ladlo Posted April 4, 2020 Author Share Posted April 4, 2020 The extended SMART test ended withouth error... The diags for the system and the smart test are attached,and the seek error rate returned to 100 value vs 67 threshold... tower-diagnostics-20200404-1016.zip tower-smart-20200404-1020.zip Quote Link to comment

Yep, everything looking fine at the moment, you might hold on on the replacement for now, just keep an eye on it, but it it happens again I would replace it. 1 Quote Link to comment
