Why we should use Jenkins instead of windows task scheduler

Posted on by

Jenkins provide a lot of utilities that we do not have it on windows task scheduler

  1. Integrated logging system : instead of writing log ourself, jenkins provide a integrated log system
  2. Succeed/Failing email notification : in task scheduler, we have to write a script to send email ourself ( i.e. using PowerShell, etc. ).
  3. Progress tracking via web-based : no need to remote desktop
  4. Manual trigger the job : no need to remote desktop

[ubuntu] wrong fs type, bad option, bad superblock

Problem : mount error

 $ sudo mount -a

mount: wrong fs type, bad option, bad superblock on Downloads,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so
# dmesg | tail

sf_read_super_aux err=-22

Solution

Need symbolic link

/sbin/mount.vboxsf -> /usr/lib/VBoxGuestAdditions/mount.vboxsf

 $ sudo ln -s /usr/lib/VBoxGuestAdditions/mount.vboxsf /sbin/mount.vboxsf
