Your start script may be calling for a specific path rather than a relative
path in your JRE.
Also try using OpenJDK instead of Oracle Java. Do a text search in your
source code for that path.

A tiny bit of history for those that may not have been around then.
Richard Stallman started the FSF and the whole open source movement because
he could not fix printing issues due to closed source drivers.

You will ultimately have problems with a corrupted file system with ext4,
almost guaranteed. Xfs is a much more robust file system but if you do not
trust it, then try zfs or btrfs.

run sar with a time argument, such as 'sar -B 5' for a report every 5

The disks are in an LVM volume group, the logical volumes are specified as

Do 'dpkg --list' to see what is installed.
Make a list of things you want to remove, i.e. 'dpkg --list | grep

Then use 'dpkg deinstall' or 'dpkg -r' for each package you want to remove,

Most times to repair a system partition, you will need to boot from a USB

You can simply check the condition with 'sudo fsck /dev/sda1'.

In your case it would be

The CSV library will handle different delimiters, quoted fields, and

In my experience, using lvm2 to mirror your disks should work for you and
be the easiest to recover since each disk has a copy of the vg
description, then vgscan will find your configuration for you. Skip using
md unless you need multipath access to a device.

Do not use EXT4, it will cause you problems down the road. Use xfs
instead, it has higher reliability and better performance.

The steps involved are pvcreate, vgscan, vgcreate, and lvcreate. The

If you are going with LVM you really do not need mdadm. On the other hand
if you build a mirror with mdadm you do not need LVM for just the mirror
