Hi, I have a server with a 2 disk Linux Software RAID 1 setup (two 80Gb disks). The first device is /dev/hde and the second is /dev/hdg. The /dev/hde device is ready to fail, as it produces various SMART errors using smartctl and fails on a self-test with: [root@gazelle root]# smartctl -l selftest /dev/hde smartctl version 5.30 Copyright (C) 2002-4 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF READ SMART DATA SECTION === SMART Self-test log structure revision number 1 Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Short offline Completed: read failure 90% 34 0x0463c0ee # 2 Short offline Completed: read failure 90% 1087 0x0425290c # 3 Extended offline Completed: read failure 90% 1072 0x0425290c # 4 Short offline Completed: read failure 90% 1072 0x0425290c # 5 Short offline Completed: read failure 90% 1071 0x0425290c The server is running Fedora Core 1. I have the new 80Gb disk and wish to replace /dev/hde device with the new disk, how do I do this? The following is how I have the mirror setup: # fdisk -l /dev/hde Disk /dev/hde: 80.0 GB, 80026361856 bytes 255 heads, 63 sectors/track, 9729 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hde1 * 1 395 3172806 b Win95 FAT32 /dev/hde2 396 408 104422+ fd Linux raid autodetect /dev/hde3 409 1070 5317515 fd Linux raid autodetect /dev/hde4 1071 9729 69553417+ f Win95 Ext'd (LBA) /dev/hde5 1071 1331 2096451 fd Linux raid autodetect /dev/hde6 1332 1585 2040223+ fd Linux raid autodetect /dev/hde7 1586 1716 1052226 fd Linux raid autodetect /dev/hde8 1717 4327 20972826 fd Linux raid autodetect /dev/hde9 4328 9729 43391533+ fd Linux raid autodetect with /dev/hdg being exactly like above. As soon as I pull out the /dev/hde device, the server won't boot (as grub only resides on /dev/hde), so I also installed grub on /dev/hdg to overcome that problem. But now I'm wondering what I must do to pull out /dev/hde and replace it with the new drive (which doesn't have any partitioning setup) and then force Linux to resync the data on /dev/hdg to the new /dev/hde? Is there some way I have to fail the /dev/hde drive, replace it then put it back on-line? First time I've done this with Software RAID so I'm not sure. Any advice is appreciated. Michael.
