I accidentally pushed the computer and it shut down (power cord moved), and after booting it again the online resync continued. the problem is that the rebuilt array is corrupted. most of the data is fine, but every several MB there is an error (which doesn't look like being caused by a crash), effectively invalidating all data on the drive (about 7TB, mainly HD video) I do monthly scans, so the redundancy syndromes should have been up-to-date, the array is made of 8 disks, the setup is ext4 on lvm on mdraid is there anything to solve this? or at least ideas what happened?
