Linuxgsm: Check free space on install & whenever required

[UltimateByte]

I saw quite a few people failing to install because of not enough free space.
Would be cool to set some space requirements for all of the servers, warning the user before installing if LGSM thinks there is not enough free space.
@dgibbs64 Please, assign one of us if you want this function.

I wish we could put this as a message :
"You can't even install that game server onto your machine because you're a jerk that has less than X GB free space in 2016. Unless required server files has gone down (which is quite unlikely) since the last time we updated server sizes in LGSM, you won't be able to install it. Do you want to continue anyway ?"

[dgibbs64]

lol. Well there is no way for me to do this as such. If we can catch the steamCMD error code for not enough disk space then we can output the error.

[UltimateByte]

The errors codes are :

Displayed to the user :

Error! App '232250' state is 0x202 after update job.

And in Steam/logs/content_log.txt:

[2016-02-14 16:14:14] AppID 232250 update canceled : Not enough disk space available in "/home/tf2server/serverfiles/steamapps/downloading/232250", 5969 MB needed, 5845 MB available (Not enough disk space)

We could add typical disk space usage into the code for every server, and make a check using :

df -h --block-size=1GB ${rootdir}

Then we could substract the server size to that result, and Warn if needed :

[WARNING] After the installation, you will only have around X GB disk space left on your partition
Continue ? yN

Or if disk space won't be enough :

[WARNING] It seems like you don't have enough disk space to install that server
Available : X GB
Required : XX GB
Continue ? yN

Then, if it encounters the typical steam error, stop the installer with an error

[ERROR] Not enough free space

@dgibbs64 This method would be applied to SteamCMD only, but it would also be great to manage the lack of free space before downloading a new server or file using an archive format, if you get what i suggest. ^^

[dgibbs64]

I like this idea I would like to confirm SteamCMD exit code for this it may be 202 im guessing. however its easy to simulate lack of disk space so this is very possible. I think this will be a feature to add after the current development branch is released

[dgibbs64]

would also like to add a disk check for updates and if the installer fails during install

Warning! SteamCMD did not complete the download, retrying: Attempt 8

I just ran into this error, rather unknowingly. I could not find a proper, simple answer to error 0x202. Eventuelly I stumbled across this issue. Google the error will show you desperate hosters trying to fix it. I think its a minor fix to just put in at least an error message, just my 2 cents. But add this to support pages or make it searchable for users would definately help.

@chriszo111 Since you seem to like wikis, please use ours to provide relevant info.
https://github.com/GameServerManagers/LinuxGSM/wiki/Support#required-information-for-support
Postdetails will help us knowing about your system and possible causes of issues.

[dgibbs64]

Yeah I think we could do with a wiki page with known steam errors. Sadly cable are not the best at this. If there is anyone who wants to research errors and put them together in a nice page that would be great!

[chriszo111]

@dgibbs64 Maybe just add a headline "Known issues" to your wiki similar to Valves Dev wiki and whenever an error pops just add the error code with a small explanation, I don't think this is to much effort. However, my purpose was solely to indicate to it.

[dgibbs64]

@chriszo111 no worry. We will look at doing something like this in the future when someone gets some free time

[exetico]

Any free-time meet by?

[UltimateByte]

Unfortunately, not much.

Some improvements to this relating to SteamCMD. LinuxGSM will now detect if SteamCMD finds a lack of disk space and print a message stating there is not enough disk space available. I believe this will satisfy this issue for most servers (apart from non-steam). I will close this and if we get reports of issues with non-steam servers then we can look at this again

relates to #719
