Hello, i'm sorry to ask this questions but the raid 5 with 4 disk is in big trouble during re-assemble. 2 disks are out of order. I have change a disk of the raid 5 (sde) to growing the raid. But a second disk (sdc) have too many bad sector during the re-assemble, and shutdown the re-assemble. "mdadm --assemble --force /dev/md2 /dev/sd[bcde]1" I have try to correct bad sectors with badblocks, but it's finished by no more spare sectors and the disk still have some bad sector. badblocks -b 512 -o badblocks-sdc.txt -v -n /dev/sdc 1140170000 1140169336 1140169400 1140169401 1140169402 1140169403 1140169404 1140169405 1140169406 1140169407 1140169416 1140169417 1140169418 1140169419 1140169420 1140169421 1140169422 1140169423 For information the mdadm examine return : cat mdadm-exam.txt /dev/sdb: MBR Magic : aa55 Partition[0] : 1953523120 sectors at 2048 (type fd) /dev/sdc: MBR Magic : aa55 Partition[0] : 1953520002 sectors at 63 (type fd) /dev/sdd: MBR Magic : aa55 Partition[0] : 1953520002 sectors at 63 (type fd) /dev/sde: MBR Magic : aa55 Partition[0] : 4294965247 sectors at 2048 (type fd) I have 2 way to solve the issue. The first, is to have special command to pass bad sector during re-assemble as "mdadm --assemble --force /dev/md2 /dev/sd[bcde]1" The second is change the disk sde with the old good one, but some datas have been changed on the raid since i have remove it. But these datas are not important. It's only logs and history activity. What can i do to recover a maximum datas without too many risk?
