if statement – How to ask for batch file user input with a timeout – Stack Overflow

Where is the Chrome settings file? – Super User

Posted by jpluimers on 2019/05/13

[WayBack] Where is the Chrome settings file? – Super User, on various platforms as a folder named Default under:

In Windows: %LocalAppData%\Google\Chrome\User Data\
In OS X: ~/Library/Application Support/Google/Chrome/
In Linux: ~/.config/google-chrome/

The easiest way to find out the actual location is by browsing to chrome://version/ as per [WayBack] google chrome – Disabling “Sign In ” tab on startup – Super User. There the entry Profile Path will show the actual profile location.

Inside that path is a JSON file called preferences which you can edit if Chrome is closed (since Chrome will overwrite it regularly when active).

A few entries I saw are interesting:

  • Restoring the session on startup: 
        "session": {
      "restore_on_startup": 1
    },
  • While running 
        "exit_type": "Crashed",
    "exited_cleanly": true,
  • After closing 
        "exit_type": "Normal",
    "exited_cleanly": true,

A trick to restore the session after you quite Chrome is to replace "exited_cleanly":true with "exited_cleanly":false in the Preferences file.

command line – How to access a usb flash drive from the terminal? – Ask Ubuntu

Posted by jpluimers on 2019/05/13

Based on [WayBack] command line – How to access a usb flash drive from the terminal? – Ask Ubuntu

Figure out the device:

  • lsblk
  • sudo blkid
  • sudo fdisk -l

Mount the device (assuming it is /dev/sdb1):

  • sudo mount /dev/sdb1 /media/usb
  • pmount /dev/sdb1
  • udisksctl mount -b /dev/sdb1

Unmounting and eject is in [WayBack] Linux (Ubuntu): safely remove USB flash disk via command line – Stack Overflow

When Ctrl-Click in a Windows VMware Fusion VM does right-click, when you thought you turned that off

Posted by jpluimers on 2019/05/10

A while ago, I was surprised that in a Windows VM running under VMware Fusion, the Ctrl-Click performed a right click, despite me having changed the configuration:

I was wrong, as I had forgotten I assigned the “Windows 8 Profile” tot hat VM (as it was running Windows 8.1), which had the Secondary Button still mapped to the Control+Primary Button:

vmware Fusion/Workstation/ – How can you boot from CD? – Super User

Posted by jpluimers on 2019/05/10

Basically the boot delay during startup is so short that usually you cannot even choose the boot device.

Solution: edit the .vmx configuration file for the Virtual Machine, then change this value:

bios.bootDelay = "15000"

VMFS metadata files

Posted by jpluimers on 2019/05/09

For my own ference:

disk space under VMFS-3 is organized according to four resource types. They are : blocks, sub-blocks, pointer blocks, and file descriptors. Resources are grouped into clusters, which form cluster groups. Every resource type is administered by one or a number of system files. Lets have a look at what those abbreviated file names stand for:

  • fbb.sf = file block bitmap.sf
  • fdc.sf = file descriptor cluster.sf
  • pbc.sf = pointer block cluster.sf
  • sbc.sf = sub-block cluster.sf
  • vh.sf = volume header.sfs
  • dd.sf = scsi device description.sf

The VMFS-5 uses one more system file:

  • pb2.sf = pointer block 2.sf

ESXi: console commands to digging through your hba/disk/datastore configuration

Posted by jpluimers on 2019/05/07

Two posts with interesting commands to help digging through your hba/disk/datastore configurations from the console:

One day I will write a script that – per datastore – lists all the devices related to it including their HBA and LUN.

For that, I will likely need these references:

For now this works:

  • Get the list of data stores (note the Device Name column has the NAA_ID you need below):
    esxcli storage vmfs extent list
  • Get the path information to find HBA, Channel, Target and LUN:
    esxcli storage core path list --device NAA_ID
  • Get the list of HBAs:
    esxcli storage core adapter list
  • Get device details (including Model and Revision):
    esxcli storage core device list --device NAA_ID

The example below (with most important output bolded) shows a drive connected to a SAS3008 based controller which storcli cannot access (nor MegaCli), but MegaRAID Storage Manager (MSM) can.

MSM allowed me to find the serial number of the drive by the Target Transport Details value 4433221106000000 as being on Slot number 6 (which seems to indicate Target numbers are 1-based whereas LUN is 0-based).

# esxcli storage vmfs extent list

BorgBackup – Deduplicating archiver with compression and authenticated encryption

Posted by jpluimers on 2019/05/06

On my research list:

Borg

Deduplicating archiver
with compression and encryption

BorgBackup (short: Borg) gives you:

  • Space efficient storage of backups.
  • Secure, authenticated encryption.
  • Compression: LZ4, zlib, LZMA.
  • Mountable backups with FUSE.
  • Easy installation on multiple platforms: Linux, macOS, BSD, …
  • Free software (BSD license).
  • Backed by a large and active open source community.

Trying to temporarily lower the ESXi acceptance level when installing VIBs

Posted by jpluimers on 2019/05/06

This is an interesting question at [WayBack] How can I lower the ESXI acceptance level when a forced install has been done? – Server Fault.

The default level on ESXi 6.5 is this:

# esxcli software acceptance get
PartnerSupported

Since I had ghettoVCB installed with the -f option, installing any PartnerSupported VIB would result in this error:

 [DependencyError]
 VIB virtuallyGhetto_bootbank_ghettoVCB_1.0.0-0.0.0 violates extensibility rule checks: ['(line 24: col 0) Element vib failed to validate content']
 VIB virtuallyGhetto_bootbank_ghettoVCB_1.0.0-0.0.0's acceptance level is community, which is not compliant with the ImageProfile acceptance level partner
 To change the host acceptance level, use the 'esxcli software acceptance set' command.
 Please refer to the log file for more details.

This fails:

# esxcli software acceptance set --level=CommunitySupported
[AcceptanceConfigError]
Unable to set acceptance level of community due to installed VIBs virtuallyGhetto_bootbank_ghettoVCB_1.0.0-0.0.0 having a lower acceptance level.
Please refer to the log file for more details.

The workaround is to uninstall virtuallyGhetto_bootbank_ghettoVCB_1.0.0-0.0.0, then install thePartnerSupportedVIB, then re-install ghettoVCB with the --force option or with lowered acceptance level:

  1. Remove the ghettoVCB installation: esxcli software vib remove -n ghettoVCB
  2. Perform the steps that ghettoVBC install prevented (install a non-community VIB, upgrade your ESXi system, etc)
  3. Reinstall the ghettoVCB by either:
