CentOS release 6.5 (final) on Xorcom Orion VX1000

Post by onifade » 2020/03/18 20:37:46

I bought a video Multipoint control unit MCU Xorcom Orion VX1000 last year Aug2019. After configuration, it worked well with HDD activity lED flashing.
Now, the HDD LED stopped flasshing and booting shows write error : no space left on device.
I could ping the ip of the server but could not open the webapage of the server.
The server runs CentOS release 6.5 (final)
please I need your contributions.

Are you able to login remotely with SSH?
If not, boot from live media and check if any partitions are full.
When you've fixed this, run yum update to get the latest CentOS version.

Yes, one of the partitions is full. Please how do we free the contents of what is taking the space on the partitions. It has 3 partitions, sda1, sda2 (9.9gb and nothing free) and sda4 (19gb with 17gb free ). Because of this, the httpd couldnt start, so we cant even access the server using the GUI. Please any help? Thank you

You have to work out what is using the space before you can fix the problem.

First step is to work out what mount point is /dev/sda2 on and then run e.g. du -m -x --max-depth=1 /mountpoint | sort -n (substituting whatever /dev/sda2 is mounted on for /mountpoint, so if /dev/sda2 is mounted on '/' then use /).

That will give you a list of the top level directories under /mountpoint in MB, sorted by size with the most used at the bottom. Now repeat that command for the subdirectory (so if /var is listed at the bottom, use /var instead of /mountpoint) that uses the most space and keep doing that until you find the bottom level directory that uses all the space.

Now you have to look at the files in there and work out if you need them. If you are unsure if you need them then you could make a backup directory on a filesystem that does still have some space and mv those files to that so that you can move them back if they are required. Don't move anything that's under /usr/bin /usr/lib /lib or anything else that the system depends on to run!

If the space is actually used by a billion tiny or 0 byte files under /tmp then you may need to use something like find /tmp -type f -size 0 -delete (dangerous! Do not run without understanding what it does and what the consequences are) which will delete all 0 byte files in /tmp. If you try to use a wildcard on a directory full of a billion files, you will get an error message about the command length from bash and it won't work which is why you need to use find with the correct arguments to only delete the things that you want to get rid of! Be careful. Also bear in mind that find operates recursively so if you ran that on - for example - /, it would delete all 0 byte files from the entire filesystem everywhere and you almost certainly do not want to do that.
