Can you explain me with an example Answer Use dpkg to install an. You want to install Ubuntu on your Windows computer, dont you The thing is, youre not 100 certain, yet. Fortunately, there are many ways in which you can try. Replacing A Failed Hard Drive In A Software RAID1 Array. Replacing A Failed Hard Drive In A Software RAID1 Array. This guide shows how to remove a failed hard drive from a Linux RAID1 array software RAID, and how to add a new hard disk to the RAID1 array without losing data. NOTE There is a new version of this tutorial available that uses gdisk instead of sfdisk to support GPT partitions. Preliminary Note. In this example I have two hard drives, devsda and devsdb, with the partitions devsda. RAID1 array devmd. RAID1 array devmd. How Do I Tell If A Hard Disk Has Failed If a disk has failed, you will probably find a lot of error messages in the log files, e. You can also runcat procmdstatand instead of the string UU you will see U if you have a degraded RAID1 array. Removing The Failed Disk. To remove devsdb, we will mark devsdb. RAID arrays devmd. Do It Yourself Program Fan Kits. First we mark devsdb. The output ofcat procmdstatshould look like this server. Personalities  linear multipath raid. F2. 44. 18. 68. 8 blocks 21 Umd. UUunused devices lt none Then we remove devsdb. The output should be like this server. Andcat procmdstatshould show this server. Personalities  linear multipath raid. Umd. 1  active raid. UUunused devices lt none Now we do the same steps again for devsdb. Proteus Vsm For Pic 16 there. Personalities  linear multipath raid. Umd. 1  active raid.

Uunused devices lt none Then power down the system shutdown h nowand replace the old devsdb hard drive with a new one it must have at least the same size as the old one if its only a few MB smaller than the old one then rebuilding the arrays will fail. Adding The New Hard Disk. After you have changed the hard disk devsdb, boot the system. The first thing we must do now is to create the exact same partitioning as on devsda. We can do this with one simple command sfdisk d devsda sfdisk devsdb. You can runfdisk lto check if both hard drives have the same partitioning now. Next we add devsdb. Now both arays devmd. Runcat procmdstatto see when its finished. During the synchronization the output will look like this server. Personalities  linear multipath raid. U.   recovery   9. Ksecmd. 1  active raid.
