I've managed to boot up using systemrescuecd and I've managed to get the RAID1 boot (/dev/md0) partition to mount. I've also looked at the RAID5 swap partition that I had forgotten about and that looks fine. The problem is with the main RAID5 device /dev/md2 which should consist of 5 partitions over 5 drives, one of which is dead and disconnected. However, when I try to use this device it will not mount, and when I look at it, it says that only 2 of the 5 devices are available. How do I get it back to using all 4 partitions? root@sysresccd /root % mdadm --detail /dev/md2 /dev/md2: Version : 0.90 Creation Time : Fri Aug 29 12:29:18 2008 Raid Level : raid5 Used Dev Size : 483492096 (461.09 GiB 495.10 GB) Raid Devices : 5 Total Devices : 2 Preferred Minor : 2 Persistence : Superblock is persistent Update Time : Thu May 13 20:27:51 2010 State : active, degraded, Not Started Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 Layout : left-symmetric Chunk Size : 256K UUID : 549f851d:f698831d:8e1f38fa:6d8d3a6f Events : 0.553056 Number Major Minor RaidDevice State 0 0 0 0 removed 1 0 0 1 removed 2 0 0 2 removed 3 8 34 3 active sync /dev/sdc2 4 8 50 4 active sync /dev/sdd2 root@sysresccd /root % -- Gary Stainburn This email does not contain private or confidential material as it may be snooped on by interested government parties for unknown and undisclosed purposes - Regulation of Investigatory Powers Act, 2000 -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
