I have a question related to the configuration of a partition-table in "Foreman". As you can see in the screenshot below, I allocate 200 GB of free space to the /-Directory.
The problem: how can I allocate the rest of free space to this partition? Your answer would really help me out... I'm looking forward!
Thanks and best regards,
You can use a combination of --grow and --maxsize
logvol / --size=1 --grow --name=lv_root --vgname=vg00
or --percent
logvol / --percent=100 --name=lv_root --vgname=vg00
Option --percent can not be used together with the --size and --grow options.

I have Chromium running on an embedded linux ARM system. What would be the best way to reduce its memory usage? I have tried running it with the "--single-process" switch, but that did not help much.
Are there any other command line switches or tips to get chromium to use less memory?
Thank you!
Pass this flags in Arguments to reduce the chromium memory usage
--disable-gpu

Hard links cannot span physical devices. Exactly this statement I read while understanding the concept of hard link in Linux. Can anyone help me to understand this ?
A filename, is a pointer to an inode.
So if you're not on the same drive, it's impossible to link a file, because the inodes belongs to a specific disk

As you can see in the picture why is the last three column is empty
It doesn't have buff/cache because that's (Block IOs) write/read cache which makes sense to have in RAM because RAM is much faster than a block device but your swap is stored on a block device, not RAM, and then you might as well read or write the data to it's actual location.
Available = free + unneeded cache and since cache doesn't exist at all in swap, available also doesn't.

How I can find out how much /tmp space is required by an application. Generally sometime I see /tmp is full and get error saying not able to write to /tmp. So is there any way to find out how much /tmp space is required by an application ?
There is no way. Programs use /tmp on an ad-hoc basis.

I have 6 very big directorys and once a day I would like to check size each of this directories for my monitoring. Now I'm using du -s command but it take many time and significantly slows my server. Is any different better way to do this?
Depending on circumstances you could put those directories on seperate partitions, the "used" size of which you can check very quickly with df.
This, of course, means that the directories are limited to the size of their respective partitions, which could be a pain. Hence the "depending on circumstances".
