Hello.. I am not sure why the "/" and "/var/tmp" on my server gets used up so quickly day in day out. I am running Litespeed and Cloudlinux on this server. Below are the specs and details. From WHM: uname -a Linux sky.example.com 3.10.0-962.3.2.lve1.5.26.3.el7.x86_64 #1 SMP Wed Aug 14 08:29:59 EDT 2019 x86_64 x86_64 x86_64 GNU/Linux df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 32G 0 32G 0% /dev tmpfs 32G 1.5M 32G 1% /dev/shm tmpfs 32G 915M 31G 3% /run tmpfs 32G 0 32G 0% /sys/fs/cgroup /dev/mapper/centos-root 50G 46G 5.0G 91% / /dev/sda1 497M 283M 214M 57% /boot /dev/mapper/centos-home 850G 121G 729G 15% /home tmpfs 6.3G 0 6.3G 0% /run/user/0 lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 931.5G 0 disk ??sda1 8:1 0 500M 0 part /boot ??sda2 8:2 0 931G 0 part ??centos-root 253:0 0 50G 0 lvm / ??centos-swap 253:1 0 31.4G 0 lvm [SWAP] ??centos-home 253:2 0 849.5G 0 lvm /home cat /etc/fstab # # /etc/fstab # Created by anaconda on Tue Feb 13 02:52:33 2018 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/centos-root / xfs defaults,uquota 0 0 UUID=2409319d-d96c-4f3b-8367-f1bcf430af58 /boot xfs defaul ts 0 0 /dev/mapper/centos-home /home xfs defaults,uquota 0 0 /dev/mapper/centos-swap swap swap defaults 0 0
I tried "yum clean all" and deleting the lshttpd/swap files from /tmp & /var/tmp manually.. but still it goes up after few minutes. Installed tmpwatch and put the cronjob to clear tmp files, still not happy with it. I would need some help in bringing down the /tmp usage as lower as possible. Also, If I move /home to a secondary SSD, can I re-arrange diskspace for "/", "/boot", and "/var/tmp" on current drive? If yes, How can I do it? Thanks in Advance. anybody helping?

  Hello, tmp is used pretty frequently by a lot of the services on your server, including mysql and php. For disk space issues like those you're encountering the best advice I can provide to you would be to contact your service provider or system administrator if you're unsure how to proceed. If you don't have a system administrator you might find one here: You might want to look at the following for the issue you're having with tmp

  I wouldn't recommend this but this is primarily something a system administrator can tell you if it's possible - on some VM systems it is possible to resize but for the most part this is going to be something you need to provision a new server for.

  Thanks.. I asked the DC to install a new SSD with custom and bigger partitions for var & tmp, installed Cpanel and other scripts and moved backup from old drive to SSD. Looks good now :)
