January 7, 20242 yr Community Expert I recently replaced a failing 4TB drive with a 14TB drive (14TB is the size of my parity disk and the largest disk size in my array) and after the rebuild completed it stated that the new drive was unmountable. I have followed the steps of running xfs_repair and am receving the following failure message. Is the data lost? root@unRaidInBlood:~# xfs_repair /dev/md9p1 Phase 1 - find and verify superblock...
