Status of a Software RAID under Linux

February 14th, 2010 Category: Linux, Linux Server

You might want to check the rebuild status of your Linux software RAID e.g. after a disc failure or a hard server crash. As you know this might take several hours, depending on the disc size.

In my case mdadm is used to configure the software RAID and mdadm –detail /dev/md1 can be used to show the rebuild status:

[root@hxxxxxxx ~]# mdadm --detail /dev/md1
/dev/md1:
Version : 00.90
Creation Time : Thu Nov  9 18:57:15 2006
Raid Level : raid1
Array Size : 159726144 (152.33 GiB 163.56 GB)
Used Dev Size : 159726144 (152.33 GiB 163.56 GB)
Raid Devices : 2
Total Devices : 2
Preferred Minor : 1
Persistence : Superblock is persistent

Update Time : Sun Feb 14 19:45:21 2010
State : active, resyncing
Active Devices : 2
Working Devices : 2
Failed Devices : 0
Spare Devices : 0

Rebuild Status : 31% complete

UUID : be29700c:083d0c62:67a9c130:e044323b
Events : 0.3626065

Number   Major   Minor   RaidDevice State
0       8        3        0      active sync   /dev/sda3
1       8       19        1      active sync   /dev/sdb3

In my case 31% of the rebuilt process are finished. We still have to wait a little bit..

Wrong Keyboard Layout with VMWare and VNC

February 8th, 2010 Category: VMWare

If you connect to your VMWare Workstation host and connect via VNC (which is a cool feature) you may recognize a wrong keyboard layout. E. g. when you have a German keyboard.

In this case just add a line (for German keyboard) into your virtual machine configuration file (.VMX):

RemoteDisplay.vnc.keymap = "de"

And your keyboard works.

Telnet for Windows 7 & Vista

February 8th, 2010 Category: General

You may have been wondering like me that no telnet command is available in Windows 7 and Vista after a fresh installation. Sometimes it’s still useful.

But it’s still available, only disabled:

  1. Open your control panel
  2. Select programs
  3. Select “Turn windows features on or off” on the left side
  4. Within the box enable [x] Telnet Client

When looking into these disabled windows features, there are features like:

  • Services for NFS
  • Subsystem for UNIX-based applications

Guess I want to check these NFS features…
