I am using your How-to - How To Set Up Software RAID1 On A Running System (Incl. GRUB2 Configuration) (Ubuntu 10.04) I am having a bit different configuration as used in the howto i have the following partitions Code: Device Boot Start End Blocks Id System /dev/sda1 * 1 2432 19530752 83 Linux /dev/sda2 2432 30402 224665601 5 Extended /dev/sda5 2432 3648 9764864 83 Linux /dev/sda6 3648 6687 24413184 83 Linux /dev/sda7 29915 30402 3906560 82 Linux swap / Solaris /dev/sda8 6687 9727 24413184 83 Linux /dev/sda9 9727 29915 162157568 83 Linux Code: sudo df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 19G 2.3G 16G 13% / none 493M 228K 492M 1% /dev none 497M 0 497M 0% /dev/shm none 497M 76K 497M 1% /var/run none 497M 0 497M 0% /var/lock none 497M 0 497M 0% /lib/init/rw /dev/sda8 23G 173M 22G 1% /tmp /dev/sda9 153G 22G 124G 15% /home /dev/sda5 9.2G 150M 8.6G 2% /usr/local /dev/sda6 23G 181M 22G 1% /var/log & also the partition type is ext3 instead of ext4 as used in howto. I dont know what is going wrong. After completing first 2 pages, when i rebooted the system, it is unable to mount all the partitions - /home, /var/log, /usr/local, /tmp Please suggest what can be done or where am I going wrong?
hey, thanks for ur reply I successfully installed software raid on my system. all thanks to howtoforge.com I was doing some mistake in mapping that's why I was getting that problem. Thanks though
You should also take the time to correctly label each partition type in the MBR so that the kernel can autodetect the RAID partitions: Code: [eric@openfiler ~]$ sudo fdisk -l /dev/sda /dev/sdb 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 / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00062e7f Device Boot Start End Blocks Id System /dev/sda1 * 63 208844 104391 83 Linux /dev/sda2 208845 8225279 4008217+ 83 Linux [COLOR="SeaGreen"]/dev/sda3 8225280 1953525167 972649944 fd Linux raid autodetect[/COLOR] 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 / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00043aa0 Device Boot Start End Blocks Id System /dev/sdb1 63 208844 104391 83 Linux /dev/sdb2 208845 8225279 4008217+ 82 Linux swap / Solaris [COLOR="SeaGreen"]/dev/sdb3 8225280 1953525167 972649944 fd Linux raid autodetect[/COLOR] [eric@openfiler ~]$ sudo cat /proc/mdstat Personalities : [raid1] md0 : active raid1 [COLOR="SeaGreen"]sda3[0] sdb3[1][/COLOR] 972648784 blocks super 1.2 [2/2] [UU]
