| | 3 | This page documents the planned steps for the Kiyoshi disk recovery (see #2828). |
| | 4 | |
| | 5 | * Install debirf image - this will allow us to boot into a debian installation loaded completely in memory giving us full access to all underlying disks |
| | 6 | * After booting into debirf: |
| | 7 | * Prepare the disks so we can access them: |
| | 8 | * Initialize the RAID arrays |
| | 9 | {{{ |
| | 10 | mdadm .... |
| | 11 | }}} |
| | 12 | * Decrypt the RAID arrays |
| | 13 | {{{ |
| | 14 | cryptsetup luksOpen /dev/md1 crypt_md1 |
| | 15 | cryptsetup luksOpen /dev/md2 crypt_md2 |
| | 16 | }}} |
| | 17 | * Scan for logical volumes |
| | 18 | {{{ |
| | 19 | vgscan --mknodes |
| | 20 | vgchange -aly |
| | 21 | }}} |
| | 22 | * Move all logical volumes to sdc2 |
| | 23 | * Find logical volumes with: |
| | 24 | {{{ |
| | 25 | lvs |
| | 26 | }}} |
| | 27 | * Examine to figure out which ones are on which physical volumes |
| | 28 | {{{ |
| | 29 | lvdisplay -m vg_kiyoshi0/<logical-volume-name> |
| | 30 | }}} |
| | 31 | * Move with: |
| | 32 | {{{ |
| | 33 | pvmove --verbose vg_kiyoshi0/<logical-volume-name> <path/to/old/> </dev/sdc> |
| | 34 | }}} |
