Good day, I'm trying to set up a software raid on Debian Wheezy 7.5 as described in this howto (with modifications suggested for Wheezy in the comments): http://www.howtoforge.com/how-to-se...ystem-incl-grub2-configuration-debian-squeeze The problem is that during step 8 - Preparing GRUB2 (Part 2), when I take a look at /boot/grub/grub.cfg, I see the following: Code: ### BEGIN /etc/grub.d/10_linux ### menuentry 'Debian GNU/Linux, with Linux 3.2.0-4-amd64' --class debian --class gnu-linux --class gnu --class os { load_video insmod gzio insmod raid insmod mdraid1x insmod part_msdos insmod part_msdos insmod ext2 set root='(mduuid/55008a4d218d5938c13b2cda87565b7e)' search --no-floppy --fs-uuid --set=root da150210-2441-4610-ae1b-48e489b129df echo 'Loading Linux 3.2.0-4-amd64 ...' linux /vmlinuz-3.2.0-4-amd64 root=/dev/md2 ro quiet echo 'Loading initial ramdisk ...' initrd /initrd.img-3.2.0-4-amd64 } There are 2 things that seem wrong to me. Firstly, the "insmod part_msdos" line is repeated 2 times. Secondly, and more importantly, the "set root" statement shows mduuid instead of (md/0). It appears that grub is not heeding that this line: Code: GRUB_DISABLE_LINUX_UUID="true" is uncommented in /etc/default/grub (I tried it both with and without quotes around "true", and of course running "update-grub" afterwards). After extensive reading, I have found the the cause is perhaps this line that gets generated: Code: search --no-floppy --fs-uuid --set=root da150210-2441-4610-ae1b-48e489b129df The only solution that I was able to find was to manually change /etc/grub.d/10_linux and /usr/lib/grub/grub-mkconfig_lib - but of course this means that these files will have to be manually changed after each update. So, my questions are: 1. Is it possible to make grub generate labels instead of uuids without hacking the above files? 2. If I decide for go for uuids instead of labels, what do I need to change? Only /etc/fstab and "set root" statement in /etc/grub.d/09_swraid1_setup? Nothing else? At the moment here's my situation. /etc/fstab: Code: /dev/md2 / ext4 errors=remount-ro 0 1 /dev/md0 /boot ext4 defaults 0 2 /dev/md1 none swap sw 0 0 /dev/sr0 /media/cdrom0 udf,iso9660 user,noauto 0 0 /dev/sdc1 /media/usb0 auto rw,user,noauto 0 0 Code: root@server1:/etc# df -h Filesystem Size Used Avail Use% Mounted on rootfs 887G 872M 841G 1% / udev 10M 0 10M 0% /dev tmpfs 1.6G 320K 1.6G 1% /run /dev/md2 887G 872M 841G 1% / tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 9.1G 0 9.1G 0% /run/shm /dev/md0 938M 35M 856M 4% /boot Code: root@server1:/etc# mount sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime) proc on /proc type proc (rw,nosuid,nodev,noexec,relatime) udev on /dev type devtmpfs (rw,relatime,size=10240k,nr_inodes=2054732,mode=755) devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000) tmpfs on /run type tmpfs (rw,nosuid,noexec,relatime,size=1645036k,mode=755) /dev/md2 on / type ext4 (rw,relatime,errors=remount-ro,user_xattr,barrier=1,data=ordered) tmpfs on /run/lock type tmpfs (rw,nosuid,nodev,noexec,relatime,size=5120k) tmpfs on /run/shm type tmpfs (rw,nosuid,nodev,noexec,relatime,size=9536840k) /dev/md0 on /boot type ext4 (rw,relatime,user_xattr,barrier=1,data=ordered) rpc_pipefs on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw,relatime) Code: root@server1:/etc# fdisk -l Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00020869 Device Boot Start End Blocks Id System /dev/sda1 * 2048 1953791 975872 fd Linux raid autodetect /dev/sda2 1953792 64454655 31250432 fd Linux raid autodetect /dev/sda3 64454656 1953523711 944534528 fd Linux raid autodetect Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdb1 * 2048 1953791 975872 fd Linux raid autodetect /dev/sdb2 1953792 64454655 31250432 fd Linux raid autodetect /dev/sdb3 64454656 1953523711 944534528 fd Linux raid autodetect Disk /dev/md0: 998 MB, 998703104 bytes 2 heads, 4 sectors/track, 243824 cylinders, total 1950592 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Disk /dev/md0 doesn't contain a valid partition table Disk /dev/md1: 32.0 GB, 31983534080 bytes 2 heads, 4 sectors/track, 7808480 cylinders, total 62467840 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Disk /dev/md1 doesn't contain a valid partition table Disk /dev/md2: 967.1 GB, 967068942336 bytes 2 heads, 4 sectors/track, 236100816 cylinders, total 1888806528 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Disk /dev/md2 doesn't contain a valid partition table Code: root@server1:/etc# cat /proc/mdstat Personalities : [raid1] md2 : active raid1 sda3[2] sdb3[1] 944403264 blocks super 1.2 [2/2] [UU] md1 : active raid1 sda2[2] sdb2[1] 31233920 blocks super 1.2 [2/2] [UU] md0 : active raid1 sda1[2] sdb1[1] 975296 blocks super 1.2 [2/2] [UU] unused devices: <none> I'll greatly appreciate your help!
