Hi, I am in serious trouble with RAID1 device. Last week we found it was in read only mode, I've stopped and tried to reassemble it with no success. dmesg recorded this error [7013959.352607] buffer_io_error: 7 callbacks suppressed [7013959.352612] Buffer I/O error on dev md126, logical block 927915504, async page read [7013959.352945] EXT4-fs (md126): unable to read superblock We've found one of the drive with various damaged sectors so we removed both and created two images first ( using ddrescue -d -M -r 10 ). We've set up two loopback devices (using losetup --partscan --find --show) and would like to recover as much as possible. Should I try to reassemble the raid with something like mdadm --assemble --verbose /dev/md0 --level=1 --raid-devices=2 /dev/loop18 /dev/loop19 Any other hints? Thanks in advance /raffaele
