My next attempt to clone the disk turned out to be a good move. I could boot the old, working drive and let it run for another day, but whit a 7 year old disk this would be a big risk. Unfortunately I was unable to fix the MBR because the BootRec utility was not able to find the windows instillation.Īt this point it was somewhere around 1 AM, the server in question needed to be working at 7AM so I was beginning to get a little nervous. About one hour later the cloning process was finished. So I booted back in to windows, shrunk the data partition about 100MB, booted back in Clonezilla and started the partition clone. Well that’s not great news, but I could still clone the separate partitions and fix the MBR using the windows installer thumb-drive. Clonezilla to the rescue, or not…Īfter booting from my Clonezilla thumb-drive and walking trough the disk cloning wizard I got an error stating that the disk could not be cloned to the new drive because the new drive is 5MB smaller. Luckily it would be able to clone the old disk to the new disk. bummer, after some googling it became apparent it would not be possible to create a mirror using this combination of disks. Unfortunately Windows disk manager came up with the following error after trying to create a new mirror: “ All disks holding extends for a given volume must have the same sector size, and the sector size must be valid.“. You just replace the defective drive, tell windows to drop the missing drive from the mirror and create a new mirror with the still working drive and the new drive. Normally, swapping a drive is super easy. So I went out, bought a new drive and told my colleagues the system would not be available in the evening. Of course the defective drive needed to be replaced as soon as possible. The server was still running fine, this is why we use RAID 1 in the first place. One Thursday morning I noticed one of the OS disks on the SQL server was showing up as missing in Windows disk manager. whether Software RAID 1 is a good solution for the situation is debatable, but this is not part of the scope for this article. At work, we have a number of servers which use the default windows software RAID implementation to insure OS disk redundancy (RAID 1).
