CentOS

Hi all,

So first of all I am a little new to CentOS as have always stuck with openSUSE before

I have been having some problems and wondering if anybody can help me but first I will describe my system. I am currently running CentOS 7 on a virtual Hyper-V machine and it has Plex running on it. My plan is to put this on a computer I have with a RAID 5 setup but before I do that I want to prove I can do everything I want to before investing more money. So now to the problems:

1) The first problem is more with Plex but there forums seem to not be able to help. The problem is when I am watching a video on a firestick streaming from the server it stops every 5-15 minutes giving me a message saying following:

Playback has stopped because the connection to the Plex Media Server has been lost. Please ensure the server is available and retry.

When I click retry it works again straight away. If I watch how much the load progress is I can see that in the first 10 seconds it loads a large chunk and then starts loading very slowly (loads less than a minute per minute of watching) so it eventually catches up and gives me the message again. I just don't understand why it is able to do a large chunk in seconds but then it slows by so much. Does anybody have any ideas?

2) The second problem came when I was putting more videos on the server via ftp. Previously there has been no problems ftping anything to the server but now when I start to upload files to the server it stops at a random percent (the percent changes each time I try with the same file). I have tried multiple files and nothing is being uploaded. I have tried having the firewall completely off in case any of the ports had reverted and that didn't help either. Interestingly I am able to download from it with no problems. Its just the upload side. I have checked the disk space and still plenty of room.

3) Which brings me onto my third problem. When I checked disk space I noticed I had used up more than I realised (still had 4 GB left thought so plenty for above). So I decided to allocate more disk space to it using Hyper V. I moved the disk space from ~40GB to 100GB. When I booted the server back up I went into fdisk and deleted sda2 created a new partition using all the available sectors. Rebooted the server and then ran following command:

pvresize /dev/sda2

However disk space has not increased.

Hope someone is able to help me as just can not get what is happening.

Thanks In Advance

Pvresize will resize the PV. You should now have freespace showing up in the VG if you run `vgs` and then you need to need to resize the LV used for the filesystem you want to adjust. Use lvresize -r to resize the filesystem at the same time.

For the rest, that sounds like a network problem. Check your logs for errors and post details of the hardware involved.

Thanks for the quick response I have run that now and looks good. Interestingly I thought I would run another check on whether I could upload to the server and now I can? I don't understand why this would suddenly work? At one point I even cleared 13 GB of space up by deleting multiple files and it wouldn't even let me upload a 350MB file. I did multiple reboots as well so no idea why? I will now check if problem 1 still exists. If it does what is the best logs for checking for network problems, thanks.
