Read-only file system hardware fault in RAID

When you are getting errors from a file system like this..   cd /hom-bash: cannot create temp file for here-document: Read-only file system -bash: cannot create temp file for here-document: Read-only file system -bash: cannot create temp file for here-document: Read-only file system You have new mail. Last login: Tue Jun 15 13:16:58 2021 from 188.118.0.104 mktemp: failed to create file via template ‘/tmp/virtualenvwrapper-initialize-hook-XXXXXXXXXX’: Read-only file system touch: cannot touch ‘’: No such file or directory ERROR: virtualenvwrapper could not create a temporary file name. It could be a hardware problem. Due to a hardware fault, you have to replace your server while taking over the hard drives. Furthermore both of my drives are faulty with one of them not even recognised by the system anymore. Mount your hard drive and back up my data and accept the full configuration loss for the server in order for us to replace them. When my server has been booted into our rescue system

Live streaming from video camera to laptop OBS Facebook, Youtube, Twitch, Restream.io RTMP server

I did a live stream a few days ago. I would save and share configuration because it was not immediately obvious how to do it.. Config camera for streaming it will be in Menu something like REC SET and choose AVCHD 1080 / 50i or XAVC S HD but or XAVC S 4K if your network connection can stream it. In my case AVCHD compression was the best choice. First step is getting video input to computer for that you need HDMI cable and a CAM Link This link is very good because all possible cameras will fit in this setup. HDMI is very useful. Next thing we need OBS obsproject.com it will convert and optimize streams for channels. Install it on your computer and configure it like in the screenshot below. Facebook stream get it from your page or account Pay attention! You can use the browser and then choose a cam link there but you can't configure speed and resolution of the stream and can get problems with bandwidth. Maybe that is a good choice to stream webcam but not successful if you want to

Other storage on your Macintosh HD

  If you look at your Mac's storage capacity, part of it will consist of an "Other" bar. At first glance, you can't tell what exactly these files are, which also makes it very difficult to delete them. The 'Other' storage bar can consist of several things. Documents, plug-ins and the cache are stored here. These files are important to keep your Mac running smoothly, but if you're not careful this part can fill up quickly. Especially if you have a MacBook with limited storage capacity, it may sometimes be necessary to slim down the amount with 'Other' storage. To do this you will first need to find the Other category. Here's how you can see how much space is taken up by other storage: Click the Apple logo at the top left of your Mac screen. Choose About This Mac > Storage. You will now see how your Mac storage is composed, including 'Others'   It may take a while before the information is visible. Now that you know how much space the

How do I add an extra / additional hard drive?

The technical support team can add an extra SSD. For installing the drive, we need to shut down your server (downtime ~ 30 min). If as requested we have added the drive to the server and restarted it. You can format the filesystem and add drive to your OS. In this case Ubuntu server. lsblk NVMe (Non-Volatile Memory Express) is a specification for accessing drives through PCI Express; it is tailored to meet the needs of non-volatile memory. For example, the connection via PCIe Gen3 x4 (32 GBit/s) provides five times faster access speed and lower latency than the traditional SATA 3 (6GBit/s) interface. Due to the high degree of parallelism and low energy consumption, they allow users to meet current and future memory needs. mkfs.ext4 -j -L backup /dev/nvme2n1  apt-get install  nvme-cli Getting information about hard drive  nvme list nvme id-ctrl /dev/nvme2n1|egrep "sn |mn " blkid /dev/nvme2n1 /dev/nvme2n1: LABEL="backup" UUID="378cdb81-98c8-44b7-95a2-22bd60a0707b
