remove openoffice reinstall libreoffice

About 6 months ago I choose to remove Libreoffice and install Open office. This was a process... things needed to be changed. However after using Open office for the past 6 months, I've learned that Libreoffice has a better interface and looks better on screen. So I wanted to return. Removed Open of...

Re: mysql does not seem to function and has no socket

In order to have a socket, MySQL needs to be started. The dameon for it has not been started. The command: service mysql start must be given. You can verify that it is running my typing: top then press i. You should see mysqld.

Now you won't have the missing socket issue.

Re: WordPress - Error establishing a database connection

I did most things right... but forgot to make sure I had more than just login password for the database. I killed it and reloaded and it's working fine. After turning over every stone... this was the one.

Re: Btrfs vs ZFS mirroring / self healing 2 4TB drives

As always... Grateful to those who provide guidance or suggestions with experience on what they speak. I am clearly out of my realm. I'm unlikely to install a VM . Had all that on Solaris, and it's not in the plan. I don't mind messing around with REAL hardware. Because at the end, I'll likely have ...

Re: Btrfs vs ZFS mirroring / self healing 2 4TB drives

I had several unsuccessful attempts to load Mint 18.2 onto a Btrfs partition . Did not provide a swap or boot partition. That may have been the issue. I prepared the 2nd drive with the same partitions, but have not loaded Mint onto them. Perhaps I should remove the FAT32 and make it Btrfs as well. I...

Re: Btrfs vs ZFS mirroring / self healing 2 4TB drives

Thanks for the additional tips... I knew about reboot... problem is I loose access to the system until I go upstairs and initialize x11vnc again. So reboots come once a day unless I get really anxious to see what's happening. There is a lot to learn about Btrfs, and I suppose reading the manual migh...

Re: Btrfs vs ZFS mirroring / self healing 2 4TB drives

My thanks to all who replied. Unfortunately I think ZFS is out of my league on this project. My machine is an ASUS High End Motherboard with AMD 8350 $ 32GB of RAM. However it is NOT ECC as the motherboard would not support it. I would have to buy a server to get that grade of equipment. And somewhe...

Btrfs vs ZFS mirroring / self healing 2 4TB drives

I'm running Nextcloud, and want DATA INTEGRITY for myself and those who use it. Backups are exceedingly slow when you get 500 GB of storage let alone down the road when others catch on to what they can do. Bought two Toshiba 4TB drives w 64MB of cache... and have spent the last two + days reviewing ...

dd, rsync or Midnight Commander for Nextcloud backup

Over the past 3 days I've investigated methods of backing up my system. The first one I tried was dd. dd was incredibly slow migrating files at aprox 7MB/sec. The next one I tried was rsync which successfully copied 410GB of files in approx 15 hours. After looking at the format of the copied files I...

Re: Fresh install on ZFS ?

Thank you for your response. Very helpful! Since I have a working system already. Perhaps what I should do is to install the two new 4TiB drives... format them for ZFS, then set up mirroring, then move the complete contents of the old drive over to the new ZFS drive pair.. Your thoughts ? I suppose ...
