Coolin72 Posted June 12, 2024 Posted June 12, 2024 (edited) Hello, I am having an issue with one of my array drives showing up as UNMOUNTABLE: UNSUPPORTED OR NO FILE SYSTEM. I plugged in a usb device (Mig Switch Dumper) that may have caused this. I rebooted and skipped parity check only to find some of my data was missing a few days later. I checked the Array and found the error message. I stopped and restarted the array and also rebooted. Here are the diags. Please help Edited June 12, 2024 by Coolin72 Quote
Coolin72 Posted June 12, 2024 Author Posted June 12, 2024 *Update* I ran sudo btrfs scrub start /dev/sdi1 and clicked Y to clear out log tree with the array offline. Result: No mapping for 10376300577106952192-10376300577106968576 Couldn't map the block 10376300577106952192 Couldn't map the block 10376300577106952192 bad tree block 10376300577106952192, bytenr mismatch, want=10376300577106952192, have=0 ERROR: failed to repair root items: Input/output error Started array and the drive is mounted and back online. Looks like clearing the log tree fixed the issue? Quote
