  1. Re: can i change mount point without data loss ?

    It depends.

    But disks aren't what OSes care about. OSes mount partitions or logical volumes, not "disks", so it could lead to massive data loss of the disk was part of a volume group that was...
  2. Re: Install Ubuntu on three Machines acting like a single Machine

    Only extremely specialized software can be used on a "cluster" in that way. That software would need to be custom created to split up tasks in such a way that different parts of the task can be run...

    Did you setup DNS for the domain?
    Did you setup an MX record for the email server on the domain?
    Did you setup an SFP text record?

  5. Re: Backup script no longer can send files to my Ubuntu server

    Plain FTP? Sending credentials, unencrypted, like that is too scary. Also, it is possible to "pull" backups, so the backup server storage isn't nearly as easily hacked. If you can't switch from...

    [ubuntu] Re: fdisk shows numerous /dev/loop

    A handy alias for df:

    alias dft='df -hT -x squashfs -x tmpfs -x devtmpfs'

    I don't know if it hides loop devices, since I don't use snaps at all, anywhere. It does remove pseudo-file systems...

    [SOLVED] Re: How to convert .mkv to .mp4 with sound?

    Perhaps if you posted the attempted commands, someone would see something wrong?

    Also, the output from mkvinfo would help. MKVs can hold many more types of video and audio than mp4 allows.

    [ubuntu] Re: Western Digital external hard disk_ 2

    That mount isn't the correct command. It is missing the directory where you want it mounted. The mount manpage explains.

    Do you have backups for that data? If not, make some to a new disk. ...
