LogicMonitor in containers

 If your LogicMonitor collector container fails to start with:

/usr/local/logicmonitor/agent/bin/logicmonitor-agent: 32: Syntax error : ")" unexpected

...allocate it more memory (e.g. from 2G to 4G).

You're welcome.  We, however, will not get the last 2 hours back.

Recovering from a Failure / SMART ERROR RAID 1 situation

The situation

You have an DL380 or similar. Your first disk has failed.  Your second disk is in SMART ERROR.

What next?

The hardware

You will need:
  • a USB adapter for mounting your disk on Windows
  • the failed disks

The software

You will need
  • Windows 10/11
  • Windows Subsystem for Linux installed

The process

  1. Attach the disk to USB via the adapter
    • If the disk is Windows-compatible, you can use freeware disk recovery tools to go from here.  Do not follow the following steps.
    • If the disk is Linux-compatible, proceed to the next step
  2. Start Disk Manager to ensure that you are able to see the disk partition
  3. Start an elevated PowerShell prompt
  4. Type:
    • wmic diskdrive list brief
  5. Note the drive that you want to mount
  6. Type (e.g.)
    •  wsl --mount \\.\PHYSICALDRIVE2
  7. If you receive an error:
    • The disk \\.\PHYSICALDRIVE2 was attached from WSL2, but failed to mount (error code: -22). For more details, run 'dmesg' inside WSL2.
    • ... then you likely have a different file system to EXT4.
  8. Enter WSL with:
    • wsl --system
  9. Look at the dmesg output by typing:
    • dmesg
  10. Look for the following (or similar):
    • [224440.126973] EXT4-fs (sde): VFS: Can't find ext4 filesystem
    • [224440.127932] ERROR: Mount:2528: mount(/dev/sde, /share/PHYSICALDRIVE2, ext4, 0x0, ) failed
  11. Note the disk, in this case "sde"
  12. Make a data directories for each partition:
    • mkdir /data1
    • mkdir /data2
    • mkdir /data3
    • ...
  13. Mount each partition - the command will fail when there are no more partitions to mount:
    • mount -t xfs /dev/sde1 /data1
    • mount -t xfs /dev/sde2 /data2
    • mount -t xfs /dev/sde3 /data3
    • ...
  14. Now copy the data off to your home directory using the rsync command (cp has issues with large files)
    • Install rsync with:
      • yum install rsync
    • Have progress bars on your file copy with (e.g.):
      • rsync --progress /data1/110/disk.0 .
  15. When you are finished, remember to unmount the partitions:
    1. umount /data1
    2. umount /data2
    3. umount /data3
    4. ...
  16. You can now unplug the drive.

New York drivers: the most important people in the world

New York drivers are the most important people in the world.  I know this because I have had to isolate with COVID in a hotel room fourteen stories above Hell's Kitchen.

When someone displeases a driver in New York, they will hold their horn down for the whole time that they can still see the vehicle that has offended them.  This is often over a minute.

Fortunately, no-one else in the whole of New York can possibly matter, because this happens at all times of day and night. 

Thanks goodness that drivers have let everyone within four blocks in this densely packed city know that they have witnessed an example of bad driving, whilst being perfect themselves.

I look forward to leaving this nightmarish hellhole and only returning when it has been pedestrianised.

    Undead LogicMonitor Devices / Resources

     Do you have seemingly dead LogicMonitor devices, with skull and crossbones, just because you have written your own DataSources, have applied "NoPing" to system.categories so the usual Host Status DataSource Group doesn't appear?

    Simply add the following lines to your DataSource's Groovy collection script (not active discovery) and viola: they're undead.

    import com.santaba.agent.live.LiveHostSet
    LiveHostSet.getInstance().flag(hostProps.get("system.deviceId").toInteger())

    Unless...

    Building healthy relationships is not an obligation. Single serve makes you happy now. Change is difficult and hard work.  The status quo is easier. Taking them for what they can afford, and get rich quick.

    This is failure.

    • Communicate openly and effectively.
    • Be who you are.
    • Celebrate them being them.
    • Deserve and give respect.
    • Connect, don't expect.
    • Keep confidences.
    • Expect better.
    • Listen completely and properly.
    • Ask for feedback.
    • Trust.
    • Respond to concerns.
    • Keep promises.
    • Apologise when appropriate.
    • Don't hide.

    Everyone.  Not just the good ones.  Everyone.

    Long term relationships are the only ones with value. Your value to the world is the change you bring.  What you bring to others is how they value you.

    But don't do this for those that respect you.  Do this for everyone.

    Those that you benefit may be there when you retire, but the list of those that you love, just for being them...  THIS is success.
