We require the raidtab to be written with tabs instead of spaces. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 Description of problem: When RAID0 or RAID1 is configured on a system, the mkinitrd is expected to include raid modules in initrd and enable autodetection/autoconfiguration of raid devices. Sometimes it fails to include raid*.o modules depending on how /etc/raidtab is written. On AS2.1, mkinitrd checks /etc/raidtab to see what level of raid is used on a system. It is done on line 378, for number in $(grep '^[ ]*raid-level' /etc/raidtab 2>/dev/null | awk '{print $2}' | LC_ALL=C sort -u) ; do In the first argument of grep, characters surrounded by brackets are expected to be [<SPACE><TAB>] but actually it only contains <TAB>. If the 'raid-level' lines in /etc/raidtab is indented with <SPACE>, mkinitrd fails to include the raid module of that level. When components of a raid array are renamed (e.g. /dev/sdd + /dev/sde => /dev/sde + /dev/sdf), the boot procedure fails to reconstruct the raid array. To workaround this, permit <TAB> only in /etc/raidtab. Version-Release number of selected component (if applicable): mkinitrd-3.4.24-0.ia64.4 How reproducible: Always Steps to Reproduce: 1. write /etc/raidtab indented with space 2. start and use raid (on ia64, set raid flag on those partitions with parted) 3. remake initrd 4. reboot with some changes of ordering and position of the components of the array Actual Results: RAID reconfiguration fails. Expected Results: RAID reconfiguration succeeds. Additional info:
