darkside40 Posted November 26, 2023 Author Share Posted November 26, 2023 Anyone an Idea? Tried to copy down the File normal with mc what failed. But althought the missing drive is not shown as emulated i can play the files which are on the missing drive, which confuses me a little bit. So is there any way i could use the not 100% Parity to correct the nearly dead drive? Quote Link to comment
itimpi Posted November 26, 2023 Share Posted November 26, 2023 According to your screenshot it IS being emulated as the emulated disk has mounted and appears to have plenty of data on it. What makes you think it is not emulated? Quote Link to comment
darkside40 Posted November 26, 2023 Author Share Posted November 26, 2023 Hmm didnt unRaid flagged such disks as emulated in past releases. I know that it is emulated else i couldnt access file which are on the damaged disk. Nevermind i started a rebuild of that disk to another 8TB i have laying around here, although i know there will be some corrupted files on it because the parity i not clean. After that i will take a look on the disabled disk with ddrescue to see which files are affected. Its only media files so no big deal. Hopefully the sync errors are gone after this, because that disk was the cause. Quote Link to comment

darkside40 Posted November 26, 2023 Author Share Posted November 26, 2023 To be honest: no i have not tried that. Quote Link to comment
darkside40 Posted November 28, 2023 Author Share Posted November 28, 2023 Okay it was not the Memory, Cable , PSU etc. it was Disk 3 which was damaged. Ran a non correcting Parity check against the rebuilded drive which ended with zero errors. Any hints how i can check the old HDD for the files which seem to be on the damaged sectors?

JorgeB Posted November 28, 2023 Share Posted November 28, 2023 Only if you are using btrfs/zfs or have pre-existing checksums for all files. Quote Link to comment
darkside40 Posted November 28, 2023 Author Share Posted November 28, 2023 So switching from ReiserFS to XFS wasnt the best choice couple of years ago. Quote Link to comment

XFS is far more resilient to problems after crashes or dodgy hardware (particularly RAM) than BTRFS is and it tends to perform better. With XFS you can install the File Integrity plugin if you want checksums. Quote Link to comment
darkside40 Posted November 28, 2023 Author Share Posted November 28, 2023 (edited) At least it is more resilient if you are notified of Filesystem errors, which unraid lacks of: Yep i think thats the way to go for my. At least checks for the mkv's etc. which ar not backed up. Edited November 28, 2023 by darkside40 Quote Link to comment
