Software Raid write various meta data on the drive. Therefor - as I understand the docs - you MUST NOT clone the drive. I use SW Raid on my private servers only, and luckily I had not so much drive failures so far. But SW Raid restored the drive on its own when I tested it a while ago. However, according to my memory, I had created a (empty) partition table. I don't remember if that was necessary or if it just happened. -- Peter Boy https://fedoraproject.org/wiki/User:Pboy pboy@xxxxxxxxxxxxxxxxx Timezone: CET (UTC+1) / CEST (UTC+2) Fedora Server Edition Working Group member Fedora docs team contributor Java developer and enthusiast _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-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/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
