ugh. without seeing all the details, unfound superblocks aren't good. if you were assembling with the wrong metadata format, that'd be unsurprising. but, it sounds like these _were_ working for you at some point. if you're hoping to explore/identify/repair any damage, there's this for a good start, https://raid.wiki.kernel.org/index.php/Recovering_a_damaged_RAID this too, https://wiki.archlinux.org/title/RAID i'd recommend subscribing asking at, https://raid.wiki.kernel.org/index.php/Asking_for_help before guessing. a much better place to ask than here. even with good help from the list, i've had mixed luck with superblock recovery -- best, when able to find multiple clean copies of backup superblocks on the array/drives. -- worst, lost it all given the change in behavior, and the older metadata, i'd consider starting fresh. wiping the array & disks, scanning/mapping bad blocks, reformatting & repartitioning, creating new arrays with lastest metadata, and restoring from backup. if you've still got good harwdare, should be good -- better than the uncertainty. yup, it'll take awhile. but, so might the hunt & repair process. -- _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
