Package: grub-pc Version: 1.98+20100804-14+squeeze1 Severity: important Tags: squeeze
This computer (Sun Thumper X4500) can only boot from two of its 48 disks, which are identified as /dev/sdy and /dev/sdac Both disks are identical and have been partitioned in exactly the same way. Then those partitions have been made into several software RAID 1 devices (md0 through md5). Root partition is md0. These are /proc/mdstat contents for that RAID device: =============== md0 : active raid1 sdac1[0] sdy1[1] 19534912 blocks [2/2] [UU] =============== If I try to install grub in the /dev/sdy disk I get some errors (I don't know if they are important or what do they mean), but apparently the process works: =============== kilimanjaro:~# grub-install /dev/sdy error: found two disks with the number 21. error: superfluous RAID member (14 found). error: found two disks with the number 21. error: superfluous RAID member (14 found). error: found two disks with the number 21. error: superfluous RAID member (14 found). error: found two disks with the number 21. error: superfluous RAID member (14 found). error: found two disks with the number 21. error: superfluous RAID member (14 found). Installation finished. No error reported =============== if I try the same with /dev/sdac, it doesn't work: =============== kilimanjaro:~# grub-install /dev/sdac error: found two disks with the number 21. error: superfluous RAID member (14 found). error: found two disks with the number 21. error: superfluous RAID member (14 found). error: found two disks with the number 21. error: superfluous RAID member (14 found). error: found two disks with the number 21. error: superfluous RAID member (14 found). error: found two disks with the number 21. error: superfluous RAID member (14 found). /usr/sbin/grub-setup: warn: Attempting to install GRUB to a partitionless disk. This is a BAD idea.. /usr/sbin/grub-setup: error: embedding is not possible, but this is required when the root device is on a RAID array or LVM volume. ================ But /dev/sdac and /dev/sdy are both partitioned, and exactly in the same way: ================ kilimanjaro:~# fdisk -l /dev/sdy Disk /dev/sdy: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00055a02 Device Boot Start End Blocks Id System /dev/sdy1 1 2432 19535008+ fd Linux raid autodetect /dev/sdy2 2433 60801 468848992+ 5 Extended /dev/sdy5 2433 4864 19535008+ fd Linux raid autodetect /dev/sdy6 4865 7296 19535008+ fd Linux raid autodetect /dev/sdy7 7297 8269 7815591 fd Linux raid autodetect /dev/sdy8 8270 15564 58597056 fd Linux raid autodetect /dev/sdy9 15565 60801 363366171 fd Linux raid autodetect kilimanjaro:~# fdisk -l /dev/sdac Disk /dev/sdac: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00050f0c Device Boot Start End Blocks Id System /dev/sdac1 1 2432 19535008+ fd Linux raid autodetect /dev/sdac2 2433 60801 468848992+ 5 Extended /dev/sdac5 2433 4864 19535008+ fd Linux raid autodetect /dev/sdac6 4865 7296 19535008+ fd Linux raid autodetect /dev/sdac7 7297 8269 7815591 fd Linux raid autodetect /dev/sdac8 8270 15564 58597056 fd Linux raid autodetect /dev/sdac9 15565 60801 363366171 fd Linux raid autodetect kilimanjaro:~# ========================== I suspect that grub-setup, as called by grub-install, is trying to install on another disk (maybe /dev/sda, since it may have chopped the last letter of the drive name, and the error would make sense since /dev/sda has no partitions and is in fact part of a RAID 5 device). But I have no idea about how to test for this without breaking anything.
